PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth the costs and expenses payable by us in connection with the sale of the securities being registered hereby.

As permitted by Section 102 of the DGCL, we have adopted provisions in our certificate of incorporation that limit or eliminate the personal liability of our directors for monetary damages for a breach of their fiduciary duty of care as a director, except for liability for:

These limitations of liability do not affect the availability of equitable remedies such as injunctive relief or rescission.

Our Second Amended and Restated Certificate of Incorporation also authorizes us to indemnify our officers, directors and other agents to the fullest extent permitted under Delaware law. As permitted by the DGCL, our Second Amended and Restated Certificate of Incorporation provides that we may indemnify, and advance expenses to, to the fullest extent permitted by law, any person who was or is a party to or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that the person is or was a director, officer, employee or agent of us, or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise.

We have also entered into separate indemnification agreements with our directors and officers that may be broader than the specific indemnification provisions contained in the DGCL.

represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in this registration statement.

Provided , however, that the undertakings set forth in paragraphs (a)(1)(i) and (a)(1)(ii) and (a)(1)(iii) above do not apply if the registration statement is on Form S-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statements or is contained in a form of prospectus filed pursuant to Rule 424(b) that is a part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided , however , that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser: (i) any preliminary prospectus

II-3

or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424; (ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant; (iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and (iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that: (i) for purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of the registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of the registration statement as of the time it was declared effective; and (ii) for the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) The undersigned registrant hereby undertakes that for the purpose of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(d) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is therefore unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933, and will be governed by the final adjudication of such issue.

(e) The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the Trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the SEC under Section 305(b)(2) of the Trust Indenture Act.

Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have examined the registration statement on Form S-3 (the “Form S-3”) filed by Astra Space, Inc., a Delaware corporation (the “Company”), with the Securities and Exchange Commission (the “Commission”) on May 2, 2023, under the Securities Act of 1933, as amended (the “Securities Act”), as amended by the Pre-Effective Amendment No. 1 to the Form S-3, filed with the Commission on May 4, 2023 (“Amendment No. 1”), and as further amended by Pre-Effective Amendment No. 2 to the Form S-3, filed with the Commission on May 8, 2023 (“Amendment No. 2,” and, together with the Form S-3 and Amendment No. 1, the “Registration Statement”). This opinion supersedes our opinion dated May 2, 2023, and previously filed as Exhibit 5.1 to the Form S-3. The Registration Statement relates to the proposed offer and sale from time to time pursuant to Rule 415 under the Securities Act of up to an aggregate offering price of $100,000,000 of (i) one or more series of debt securities of the Company, which may be either senior, senior subordinated or subordinated debt securities (the “Debt Securities”), (ii) shares of the Company’s preferred stock, par value $0.0001 per share (the “Preferred Stock”), (iii) shares of the Company’s Class A common stock, par value $0.0001 per share (the “Common Stock”), (iv) debt warrants to purchase Debt Securities (the “Debt Warrants”) and equity warrants to purchase Preferred Stock or Common Stock (the “Equity Warrants” and together with the Debt Warrants, the “Warrants”), (v) rights to purchase shares of Common Stock (the “Rights”), and (vi) units consisting of two or more of the Securities (as defined below) (the “Units”). The Debt Securities, Preferred Stock, Common Stock, Warrants, Rights and Units are collectively referred to herein as the “Securities.” The Debt Securities and Preferred Stock may be exchangeable for or convertible into other Securities of the Company, including Common Stock or Preferred Stock.

The Securities may be offered and sold from time to time by the Company as set forth in the Registration Statement, the prospectus contained within the Registration Statement (the “Prospectus”), and one or more supplements to the Prospectus (each, a “Prospectus Supplement”). The Debt Securities may be issued pursuant to an indenture by and between the Company and a financial institution to be identified therein as trustee in the form included as Exhibit 4.6 to the Registration Statement, as such indenture may be supplemented from time to time (the “Indenture”). The Warrants may be issued under one or more warrant agreements (each, a “Warrant Agreement”) by and between the Company and a bank or trust company to be identified therein as warrant agent. The Rights may be issued under one or more rights agreements in a form to be filed and incorporated into the Registration Statement (each, a “Rights Agreement”) to be entered into by and between the Company and a bank, trust company or other financial institution to be identified therein as rights agent. The Units may be issued under one or more unit agreements (each, a “Unit Agreement”) between the Company and a third party to be identified therein as unit agent. The Indenture, each Warrant Agreement, each Rights Agreement and each Unit Agreement are herein collectively called the “Agreements.”

This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement, the Prospectus or any Prospectus Supplement.

In rendering the opinions set forth below, we have examined and relied upon the Registration Statement, the Prospectus, the Company’s Second Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, as currently in effect, and the originals or copies certified to our satisfaction of such records, documents, certificates, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinion expressed below. Based upon the foregoing and subject to the limitations, assumptions, exceptions and qualifications expressed herein, it is our opinion that, as of the date hereof, with respect to each of the matters set forth in Paragraphs 1 through 6 below:

1. With respect to shares of Common Stock, when the issuance of Common Stock has been duly authorized by all necessary corporate action of the Company, upon issuance, delivery and payment therefor (not less than the par value of the Common Stock) in the manner contemplated by the Registration Statement, the Prospectus and related Prospectus Supplement(s) and in accordance with the applicable definitive purchase, underwriting or similar agreement approved by the board of directors or upon conversion or exercise of any other Security in accordance with its terms, such shares of Common Stock will be validly issued, fully paid and nonassessable.
