Description of Organization and Business Operations	OSPREY TECHNOLOGY ACQUISITION CORP. NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2020 NOTE 1—DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS Osprey Technology Acquisition Corp. (the “Company”) was incorporated in Delaware as a blank check company under the name “Osprey Acquisition Corp. II” on June 15, 2018. The Company changed its name to “Osprey Energy Acquisition Corp. II” on September 27, 2018 and then to “Osprey Technology Acquisition Corp.” on June 17, 2019. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company has generated no revenues to date and it does not expect that it will generate operating revenues until it consummates an initial business combination at the earliest. Although the Company may pursue an acquisition opportunity in any business or industry, it intends to focus on opportunities in the technology sector, particularly companies pursuing a Software-as-a-Service The Company has one subsidiary, Osprey Technology Merger Sub, Inc., a direct wholly owned subsidiary of the Company incorporated in Delaware on February 16, 2021. (“Merger Sub”) (see Note 13). As of December 31, 2020, the Company had not commenced operations. All activity through December 31, 2020 relates to the Company’s formation, the initial public offering (the “Initial Public Offering”), which is described below which is described below, identifying a target company for a Business Combination, activities in connection with the proposed acquisition of BlackSky Holdings, Inc., a Delaware corporation (“ BlackSky The registration statements for the Company’s Initial Public Offering were declared effective on October 31, 2019. On November 5, 2019, the Company consummated the Initial Public Offering of 27,500,000 units (the “Units” and, with respect to the shares of Class A common stock included in the Units sold, the “Public Shares”), at $10.00 per Unit, generating gross proceeds of $275,000,000, which is described in Note 5. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 7,500,000 warrants (the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant in a private placement to Osprey Sponsor II, LLC (the “Sponsor”), generating gross proceeds of $7,500,000, which is described in Note 6. Following the closing of the Initial Public Offering on November 5, 2019, an amount of $275,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”) and invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 On November 11, 2019, the underwriters notified the Company of their intention to exercise their over-allotment option in full on November 13, 2019. As such, on November 13, 2019, the Company consummated the sale of an additional 4,125,000 Units, at $10.00 per Unit, and the sale of an additional 825,000 Private Placement Warrants, at $1.00 per Private Placement Warrant, generating total gross proceeds of $42,075,000. A total of $41,250,000 of the net proceeds was deposited into the Trust Account, bringing the aggregate proceeds deposited in the Trust Account to $316,250,000. Transaction costs for the Initial Public Offering amounted to $18,047,876 consisting of $6,325,000 of underwriting fees, $11,068,750 of deferred underwriting fees and $654,126 of other offering costs. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The Company’s initial Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (excluding the deferred underwriting fees and taxes payable on income earned on the Trust Account) at the time of the signing an agreement to enter into a Business Combination. The Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company will provide its holders of the outstanding Public Shares (the “public stockholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The public stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then on deposit in the Trust Account ($10.00 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its franchise and income tax obligations). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. The Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the outstanding shares voted are voted in favor of the Business Combination. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation, conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (the “SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem Public Shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the Company’s Sponsor has agreed to vote its Founder Shares (as defined below in Note 6) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. Notwithstanding the foregoing, if the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Company’s Amended and Restated Certificate of Incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Public Shares, without the prior consent of the Company. The Sponsor and the Company’s officers and directors have agreed (a) to waive their redemption rights with respect to their Founder Shares and Public Shares held by them in connection with the completion of a Business Combination and (b) not to propose an amendment to the Company’s Amended and Restated Certificate of Incorporation (a) that would modify the substance or timing of the Company’s obligation to allow redemption in connection with a Business Combination or to redeem 100% of its Public Shares if the Company does not complete a Business Combination or (b) with respect to any other provision relating to stockholders’ rights or pre-initial The Company will have until November 5, 2021 to consummate a Business Combination (the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share The Sponsor has agreed to waive its liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Sponsor or any of the Company’s officers, directors or any of their affiliates acquires Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 8) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Initial Public Offering price per Unit ($10.00). In order to protect the amounts held in the Trust Account, Mr. Jonathan Cohen, the Company’s Co-Chairman, Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, Mr. Jonathan Cohen will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that Mr. Jonathan Cohen will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Risks and Uncertainties Management continues to evaluate the impact of the COVID-19

Prior Period Adjustment [Abstract]
Restatement Of Previously Issued Financial Statements	NOTE 2 — RESTATEMENT OF PREVIOUSLY ISSUED FINANCIAL STATEMENTS The Company previously accounted for its outstanding Public Warrants (as defined in Note 4) and Private Placement Warrants issued in connection with its Initial Public Offering as components of equity instead of as derivative liabilities. The warrant agreement governing the warrants includes a provision that provides for potential changes to the settlement amounts dependent upon the characteristics of the holder of the warrant. In addition, the warrant agreement includes a provision that in the event of a tender or exchange offer made to and accepted by holders of more than 50% of the outstanding shares of a single class of common shares, all holders of the warrants would be entitled to receive cash for their warrants (the “tender offer provision”). In connection with the audit of the Company’s financial statements for the year ended December 31, 2020, the Company’s management further evaluated the warrants under Accounting Standards Codification (“ASC”) Subtopic 815-40, Section 815-40-15 Section 815-40-15, Section 815-40-15 fixed-for-fixed Section 815-40-25. As a result of the above, the Company should have classified the warrants as derivative liabilities in its previously issued financial statements. Under this accounting treatment, the Company is required to measure the fair value of the warrants at the end of each reporting period and recognize changes in the fair value from the prior period in the Company’s operating results for the current period ( S The Company’s accounting for the warrants as components of equity instead of as derivative liabilities did not have any effect on the Company’s previously reported operating expenses or cash.

Liquidation And Going Concern Disclosure [Abstract]
Liquidity and Going Concern	NOTE 3—LIQUIDITY AND GOING CONCERN As of December 31, 2020, the Company had $399,516 in its operating bank accounts, $318,041,728 in marketable securities held in the Trust Account to be used for a Business Combination or to repurchase or redeem its Public Shares in connection therewith and a working capital deficit of $1,627,973, which excludes franchise taxes payable of $40,050 and prepaid income taxes of $255,364. As of December 31, 2020, approximately $1,792,000 of the amount on deposit in the Trust Account represented interest income and unrealized gains, which is available to pay the Company’s tax obligations, if any. Until the consummation of a Business Combination, the Company will be using the funds not held in the Trust Account for identifying and evaluating target businesses, performing due diligence on prospective target businesses, traveling to and from the offices, plants or similar location of prospective target businesses or their representatives or owners, reviewing corporate documents and material agreements of prospective target businesses and structuring, negotiating and completing a Business Combination. The Company will need to raise additional capital through loans or additional investments from its Sponsor, an affiliate of the Sponsor, or its officers or directors. The Company’s officers, directors and Sponsor, or their affiliates, may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. These conditions raise substantial doubt about the Company’s ability to continue as a going concern through November 5, 2021, which is the date the Company is required to cease all operations except for the purpose of winding up if it has not completed a Business Combination. These financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.

Summary Of Significant Accounti

Summary Of Significant Accounting Policies	Dec. 31, 2020
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 4—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the SEC. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging Use of Estimates The preparation of the financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of December 31, 2020 and 2019. Marketable Securities Held in Trust Account At December 31, 2020 and 2019, the assets held in the Trust Account were substantially held in U.S. Treasury Bills. Class A common Stock Subject to Possible Redemption The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Shares Class A common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s Class A common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, Class A common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheets. Deferred Offering Costs Deferred offering costs consist of accounting and legal expenses incurred through the balance sheet date that are directly related to the Initial Public Offering. Deferred offering costs will be allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Upon completion of the Initial Public Offering, offering costs associated with warrant liabilities have been expensed, and presented as non-operating expenses in the statement of operations and offering costs associated with the Class A common stock have been charged to stockholders’ equity. Warrant Liability The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own common shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in Income Taxes The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2020 and 2019. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company may be subject to potential examination by federal, state and city taxing authorities in the areas of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with federal, state and city tax laws. The Company is subject to income tax examinations by major taxing authorities since inception. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. On March 27, 2020, the CARES Act was enacted in response to COVID-19 Net Income (Loss) Per Common Share Net income (loss) per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period. The Company has not considered the effect of the warrants sold in the Initial Public Offering and private placement to purchase an aggregate of 24,137,500 shares in the calculation of diluted loss per share, since the exercise of the warrants are contingent upon the occurrence of future events and the inclusion of such warrants would be anti-dilutive. The Company’s statements of operations includes a presentation of income (loss) per share for common shares subject to possible redemption in a manner similar to the two-class Net income (loss) per share, basic and diluted, for non-redeemable non-redeemable Non-redeemable non-redeemable Non-redeemable non-redeemable The following table reflects the calculation of basic and diluted net income (loss) per common share (in dollars, except per share amounts): Year Ended Year Ended Class A Common stock subject to possible redemption Numerator: Earnings allocable to Class A common stock subject to possible redemption Interest earned on marketable securities held in Trust Account $ 1,492,477 $ 632,256 Unrealized gain (loss) on marketable securities held in Trust Account 2,868 (5,729 ) Less: interest available to be withdrawn for payment of taxes (240,068 ) (186,104 ) Net income attributable to Class A common stock subject to possible redemption $ 1,255,278 $ 440,42 3 Denominator: Weighted Average Class A Common stock subject to possible redemption Basic and diluted weighted average shares outstanding, Class A common stock subject to possible redemption 27,639,376 28,129,383 Basic and diluted net income per share, Class A common stock subject to possible redemption $ 0.05 $ 0.02 Non-Redeemable Numerator: Net Loss minus Net Earnings Net loss $ (15,265,396 ) $ (7,209,680 ) Less: Net income allocable to Class A Common stock subject to possible redemption (1,255,278 ) (440,42 3 ) Non-Redeemable $ (16,520,674 ) $ (7,650,103 ) Denominator: Weighted Average Non-Redeemable Basic and diluted weighted average shares outstanding, Non-redeemable 11,891,874 7,814,396 Basic and diluted net loss per share, Non-redeemable $ (1.39 ) $ (0.98 ) Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on these accounts. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheets, primarily due to their short-term nature. Recent Accounting Standards Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statements.

Each Private Placement Warrant is exercisable to purchase one share of Class A common stock at an exercise price of $11.50. The proceeds from the Private Placement Warrants were added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Warrants will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law), and all underlying securities will expire worthless. At the date of the IPO, the fair value of the Private Placement Warrants was $0.62. The difference between the purchase price of $1 and the fair value at the IPO date of $0.62 was recorded within equity as a contribution in excess of the fair value of the Private Placement Warrants.

Related Party Transactions	NOTE 7—RELATED PARTY TRANSACTIONS Founder Shares In June 2018, the Sponsor purchased 125,000 shares (the “Founder Shares”) of the Company’s Class B common stock for an aggregate price of $25,000. In September 2018, the Company effectuated a 69-for-1 as-converted one-for-one The Sponsor has agreed, subject to certain limited exceptions, not to transfer, assign or sell any of its Founder Shares until the earlier to occur of: (i) one year after the completion of a Business Combination or (ii) the date on which the Company completes a liquidation, merger, capital stock exchange or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of common stock for cash, securities or other property. Notwithstanding the foregoing, if the last sale price of the Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading lock-up. Administrative Support Agreement The Company entered into an agreement whereby, commencing on November 5, 2019, the Company agreed to pay the Sponsor a total of $10,000 per month for office space, utilities and secretarial and administrative support. Upon completion of the Business Combination or the Company’s liquidation, the Company will cease paying these monthly fees. For the year ended December 31, 2020 and 2019, the Company incurred and paid $120,000 and $20,000 in fees for these services, respectively. Promissory Note—Related Party On September 12, 2018, the Company issued an unsecured promissory note to the Sponsor (the “Promissory Note”), pursuant to which the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover expenses related to the Initial Public Offering. The Promissory Note was non-interest Related Party Loans In order to finance transaction costs in connection with a Business Combination, the Sponsor, an affiliate of the Sponsor, or the Company’s officers and directors may, but are not obligated to, loan the Company funds from time to time or at any time, as may be required (“Working Capital Loans”). Each Working Capital Loan would be evidenced by a promissory note. The Working Capital Loans would either be paid upon consummation of a Business Combination, without interest, or, at the holder’s discretion, up to $1,500,000 of the Working Capital Loans may be converted into warrants at a price of $1.00 per warrant. The warrants would be identical to the Private Placement Warrants. In the event that a Business Combination does not close, the Company may use a portion of the proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans.

Commitments	NOTE 8—COMMITMENTS Registration Rights Pursuant to a registration rights agreement entered into on October 31, 2019, the Sponsor and holders of warrants issued upon conversion of Working Capital Loans, if any, will have registration rights to require the Company to register a sale of any of its securities held by them (in the case of the Founder Shares, only after conversion to Class A common stock). These holders will be entitled to make up to three demands, excluding short form registration demands, that the Company register such securities for sale under the Securities Act. In addition, these holders will have “piggy-back” registration rights to include such securities in other registration statements filed by the Company and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act.

Warrant Liability [Abstract]
Warrant Liabilities	NOTE 10—WARRANT LIABILITIES Warrants Once the warrants become exercisable, the Company may redeem the Public Warrants: • in whole and not in part; • at a price of $0.01 per warrant • upon not less than 30 days’ prior written notice of redemption; • if, and only if, the reported last sale price of the Company’s Class A common stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading • If, and only if, there is a current registration statement in effect with respect to the shares of Class A common stock underlying such warrants. The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A common stock issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and be non-redeemable In addition, (x) if the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of shares of Class A common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. Additionally, in no event will the Company be required to net cash settle the warrants. If the Company issues additional shares of Class A common stock or equity-linked securities for capital raising purposes in connection with the closing of a Business Combination at a newly issued price of less than $9.20 per share of Class A common stock (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by them, as applicable, prior to such issuance), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (z) the market value (as defined in the warrant agreement) is below $9.20 per share, the exercise price of the Public Warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the market value and the newly issued price, and the $18.00 per share redemption trigger price described above will be adjusted (to the nearest cent) to be equal to 180% of the higher of the market value and the newly issued price. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with respect to such warrants. Accordingly, the warrants may expire worthless.

Income Tax	NOTE 11 — INCOME TAX The Company’s net deferred tax assets are as follows: December 31, 2020 2019 Deferred tax assets Net operating loss carryforward $ 290,402 $ — Unrealized (gain) loss on marketable securities (7,818 ) 1,361 Total deferred tax assets 282,584 1,361 Valuation Allowance (282,584 ) — Deferred tax assets, net valuation allowance $ — $ 1,361 The income tax provision consists of the following: As of December 31, 2020 2019 Federal Current $ — $ 94,636 Deferred (281,223 ) (1,361 ) State and Local Current — — Deferred — — Change in valuation allowance 282,584 — Income tax provision $ 1,361 $ 93,275 As of December 31, 2020 and 2019, the Company had $1,382,869 and $0 of U.S. federal and state net operating loss carryovers available to offset future taxable income. In assessing the realization of the deferred tax assets, management considers whether it is more likely than not that some portion of all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance. For the year ended December 31, 2020 and 2019, the change in the valuation allowance was $282,584 and $0. A reconciliation of the federal income tax rate to the Company’s effective tax rate is as follows: December 31, December 31, Statutory federal income tax rate 21.0 % 21.0 % State taxes, net of federal tax benefit 0.0 % 0.0 % Change in fair value of warrant liability (19.2 )% (20.7 )% Transaction costs allocable to warrant liabilities 0.0 % (1.7 )% Valuation allowance (1.9 )% 0.0 % Income tax provision (0.1 )% (1.4 )% The Company files income tax returns in the U.S. federal jurisdiction and is subject to examination by the various taxing authorities. The Company’s tax returns since inception remain open to examination by the taxing authorities.

Fair Value Disclosures [Abstract]
Fair value measurements	NOTE 12—FAIR VALUE MEASUREMENTS The Company follows the guidance in ASC 820 for its financial assets and liabilities that are re-measured non-financial re-measured The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities: Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active. Level 3: Unobservable inputs based on the Company’s assessment of the assumptions that market participants would use in pricing the asset or liability. The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis at December 31, 2020 and, 2019, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value: Description Level December 31, December 31, Assets: Marketable securities held in Trust Account 1 $ 318,041,728 $ 316,958,514 Liabilities: Warrant Liability – Public Warrants 1 23,244,375 14,231,250 Warrant Liability – Private Placement Warrants 3 12,487,500 7,575,750 The Warrants were accounted for as liabilities in accordance with ASC 815-40 The Private and Public Warrants were initially valued using a Binomial Lattice Model, which is considered to be a Level 3 fair value measurement. The Binomial Lattice Model’s primary unobservable input utilized in determining the fair value of the Public and Private Warrants is the expected volatility of the common stock. The expected volatility as of the IPO date was derived from observable public warrant pricing on comparable ‘blank-check’ companies without an identified target. The expected volatility as of subsequent valuation dates was implied from the Company’s own public warrant pricing. A Binomial Lattice Model was used in estimating the fair value of the public warrants for periods where no observable traded price were available, using the same expected volatility as was used in measuring the fair value of the Private Warrants. For periods subsequent to the detachment of the warrants from the Units, the close price of the public warrant price was used as the fair value as of each relevant date. The key inputs into the Binomial Lattice Model for the initial measurement of Public Warrants and Private Placement Warrants and subsequent measurement of the Private Place Warrants are as follows: Input November 5, (Initial December 31, March 31, June 30, September 30, December 31, Risk-free interest rate 1.66 % 1.76 % 0.45 % 0.35 % 0.32 % 0.38 % Market price of public stock $ 9.69 9.78 9.72 10.05 10.19 10.47 Dividend Yield 0.0 % 0.0 % 0.0 % 0.0 % 0.0 % 0.0 % Implied volatility 10.7 % 13.8 % 14.4 % 17.9 % 22.1 % 21.8 % Exercise price $ 11.50 11.50 11.50 11.50 11.50 11.50 On November 5, 2019, the Private Placement Warrants and Public Warrants were determined to be $0.62 and $0.61 per warrant for aggregate values of $4.7 million and $8.4 million, respectively. On December 31, 2019, the Private Placement Warrants and Public Warrants were determined to be $0.91 and $0.90 per warrant for aggregate values of $7.6 million and $14.2 million, respectively. On December 31, 2020, the Private Placement Warrants and Public Warrants were determined to be $1.50 and $1.47 per warrant for aggregate values of $12.5 million and $23.2 million, respectively. The following table presents the changes in the fair value of warrant liabilities: Private Public Warrant Fair value as of January 1, 2018 — — — Initial measurement on November 5, 2019 (IPO) 4,650,000 8,387,500 13,037,500 Initial measurement on November 13, 2019 (over-allotment) 511,500 1,258,125 1,769,625 Change in valuation inputs or other assumptions 2,414,250 4,585,625 6,999,875 Fair value as of December 31, 2019 7,575,750 14,231,250 21,807,000 Change in valuation inputs or other assumptions (1,914,750 ) (3,478,750 ) (5,393,000 ) Fair value as of March 31, 2020 5,661,000 10,752,500 16,413,500 Change in valuation inputs or other assumptions 3,163,500 5,850,625 9,014,125 Fair value as of June 30, 2020 8,824,500 16,603,125 25,427,625 Change in valuation inputs or other assumptions 3,080,250 5,534,375 8,614,625 Fair value as of September 30, 2020 11,904,750 22,137,500 34,042,250 Change in valuation inputs or other assumptions 582,750 1,106,875 1,689,625 Fair value as of December 31, 2020 12,487,500 23,244,375 35,731,875 Fair value as of January 1, 2018 $ — $ — $ — Initial measurement on November 5, 2019 4,650,000 8,387,500 13,037,500 Initial measurement on November 13, 2019 (over-allotment) 511,500 1,258,125 1,769,625 Change in valuation inputs or other assumptions 2,414,250 4,585,625 6,999,875 Fair value as of December 31, 2019 7,575,750 14,231,250 21,807,000 Change in valuation inputs or other assumptions 4,911,750 9,013,125 13,924,875 Fair value as of December 31, 2020 $ 12,487,500 $ 23,244,375 $ 35,731,875 Due to the use of quoted prices in an active market (Level 1) to measure the fair value of the Public Warrants, subsequent to initial measurement, the Company had transfers out of Level 3 totaling $9,645,625 during the period from November 11, 2019 through December 31, 2019.

Subsequent Events [Abstract]
Subsequent Events	NOTE 13—SUBSEQUENT EVENTS The Company evaluated subsequent events and transactions that occurred after the balance sheet date up to the date that the financial statements were issued. Based upon this review, other than as described below and in Note 2, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements. On February 17, 2021, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Merger Sub and BlackSky, which provides for, among other things, the merger of Merger Sub with and into BlackSky, with BlackSky continuing as the surviving entity (the “Merger” and, collectively with the other transactions contemplated by the Merger Agreement, the “Transactions”). The Transactions set forth in the Merger Agreement, including the Merger, will constitute a “Business Combination”. Pursuant to the Merger Agreement, the aggregate merger consideration payable to equity holders of BlackSky at closing (the “Total Consideration”) will be paid in a number of shares of newly-issued Class A common stock of the Company, valued at $10.00 per share (the “Company Common Stock”), calculated by dividing (x) $925,000,000, plus (a) the aggregate exercise prices that would be paid to BlackSky if all stock options and all warrants outstanding as of immediately prior to the closing were exercised in full, minus (b) any unfunded amount under BlackSky’s bridge loan, minus (c) the total consideration payable to shares of BlackSky’s Class B common stock, which is equal to the product of (i) the total number of shares of BlackSky’s Class B common stock, par value $0.00001 per share, issued and outstanding as of immediately prior to the effective time of the Merger and (ii) an amount in cash equal to $0.00001 by (y) $10.00. Effective as of the effective time of the Merger and by virtue of the Merger, each option to purchase shares of BlackSky Class A Common Stock (each, a “BlackSky Stock Option”) that is outstanding and unexercised as of immediately prior to the effective time of the Merger will be converted into an option to acquire a number of shares of Company Class A Common Stock equal to the product obtained by multiplying (x) the number of shares of BlackSky Common Stock subject to the applicable BlackSky Stock Option by (y) the Class A Common Exchange Ratio, and will be subject to the same terms and conditions as were applicable to such BlackSky Stock Option (each an “Assumed Company Stock Option”). For purposes of the Merger Agreement, the Class A Common Exchange Ratio equals the quotient of (A) the residual Total Consideration after taking into account the preferred series preference amounts, divided by $10.00, divided by (B) the number of participating shares of BlackSky Common Stock on a fully diluted basis. The exercise price per share of each Assumed Company Stock Option will be equal to the quotient obtained by dividing (x) the exercise price per share applicable to such BlackSky Stock Option by (y) the Class A Common Exchange Ratio. The Transaction will be consummated subject to the deliverables and provisions as further described in the Merger Agreement.

Summary Of Significant Accounting Policies (Policies)	Dec. 31, 2020
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the SEC.
Emerging Growth Company	Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.
Cash and cash Equivalents	Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of December 31, 2020 and 2019.
Marketable Securities Held in Trust Account	Marketable Securities Held in Trust Account At December 31, 2020 and 2019, the assets held in the Trust Account were substantially held in U.S. Treasury Bills.
Common Stock Subject to Possible Redemption	Class A common Stock Subject to Possible Redemption The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Shares Class A common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s Class A common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, Class A common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheets.
Deferred offering costs	Deferred Offering Costs Deferred offering costs consist of accounting and legal expenses incurred through the balance sheet date that are directly related to the Initial Public Offering. Deferred offering costs will be allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Upon completion of the Initial Public Offering, offering costs associated with warrant liabilities have been expensed, and presented as non-operating expenses in the statement of operations and offering costs associated with the Class A common stock have been charged to stockholders’ equity.
Warrant Liability	Warrant Liability The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own common shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in
Income Taxes	Income Taxes The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2020 and 2019. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company may be subject to potential examination by federal, state and city taxing authorities in the areas of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with federal, state and city tax laws. The Company is subject to income tax examinations by major taxing authorities since inception. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. On March 27, 2020, the CARES Act was enacted in response to COVID-19
Net Loss Per Common Share	Net Income (Loss) Per Common Share Net income (loss) per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period. The Company has not considered the effect of the warrants sold in the Initial Public Offering and private placement to purchase an aggregate of 24,137,500 shares in the calculation of diluted loss per share, since the exercise of the warrants are contingent upon the occurrence of future events and the inclusion of such warrants would be anti-dilutive. The Company’s statements of operations includes a presentation of income (loss) per share for common shares subject to possible redemption in a manner similar to the two-class Net income (loss) per share, basic and diluted, for non-redeemable non-redeemable Non-redeemable non-redeemable Non-redeemable non-redeemable The following table reflects the calculation of basic and diluted net income (loss) per common share (in dollars, except per share amounts): Year Ended Year Ended Class A Common stock subject to possible redemption Numerator: Earnings allocable to Class A common stock subject to possible redemption Interest earned on marketable securities held in Trust Account $ 1,492,477 $ 632,256 Unrealized gain (loss) on marketable securities held in Trust Account 2,868 (5,729 ) Less: interest available to be withdrawn for payment of taxes (240,068 ) (186,104 ) Net income attributable to Class A common stock subject to possible redemption $ 1,255,278 $ 440,42 3 Denominator: Weighted Average Class A Common stock subject to possible redemption Basic and diluted weighted average shares outstanding, Class A common stock subject to possible redemption 27,639,376 28,129,383 Basic and diluted net income per share, Class A common stock subject to possible redemption $ 0.05 $ 0.02 Non-Redeemable Numerator: Net Loss minus Net Earnings Net loss $ (15,265,396 ) $ (7,209,680 ) Less: Net income allocable to Class A Common stock subject to possible redemption (1,255,278 ) (440,42 3 ) Non-Redeemable $ (16,520,674 ) $ (7,650,103 ) Denominator: Weighted Average Non-Redeemable Basic and diluted weighted average shares outstanding, Non-redeemable 11,891,874 7,814,396 Basic and diluted net loss per share, Non-redeemable $ (1.39 ) $ (0.98 ) Year Ended Year Ended Less: Net income allocable to Class A Common stock subject to possible redemption (1,255,278 ) (440,423 ) Non-Redeemable $ (16,520,674 ) $ (7,650,103 ) Denominator: Weighted Average Non-Redeemable Basic and diluted weighted average shares outstanding, Non-redeemable 11,891,874 7,814,396 Basic and diluted net loss per share, Non-redeemable $ (1.39 ) $ (0.98 )
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on these accounts.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheets, primarily due to their short-term nature.
Recent Accounting Standards	Recent Accounting Standards Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statements.
