This Schedule 13D relates to the Class A Shares of Constellation Acquisition Corp. I (the "Issuer"). The address of the Issuer's principal executive offices is 200 Park Avenue, 32nd Floor, New York, NY 10166.

**Item 2. Identity and Background**

(a) This Schedule 13D is being filed jointly by Constellation Sponsor LP and Antarctica Endurance Manager, LLC (together, the "Reporting Persons," and each, a "Reporting Person").

(b) The address and principal office of the Reporting Persons is 200 Park Avenue, 32nd Floor, New York, NY 10166.

(c) Antarctica Endurance Manager, LLC is the general partner of Constellation Sponsor LP. Therefore, Antarctica Endurance Manager, LLC may be deemed to have voting and dispositive power over 7,633,750 Class B Shares and 5,466,667 Private Placement Warrants.

(d)-(e) None of the Reporting Persons has, during the last five years: (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors); or (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

(f) The Reporting Persons are incorporated in Delaware.

**Item 3. Source and Amount of Funds or Other Consideration.**

On January 26, 2023, the Issuer entered into an Investment Agreement (the "Investment Agreement") with Constellation Sponsor GmbH & Co. KG, a German limited partnership (the "Former Sponsor"), and Endurance Constellation, LLC, a Delaware limited liability company (the "Investor"), pursuant to which the Investor agreed to contribute to the Former Sponsor an aggregate amount in cash equal up to $3,000,000 (the "Investment Contribution"), which amount will be loaned to the Issuer in accordance with an unsecured promissory note, in consideration for which, the New Sponsor (as defined below) shall issue to the Investor interests in certain equity securities. On January 30, 2023, the Issuer issued the unsecured promissory note in the total principal amount of up to $3,000,000 to the New Sponsor, and the New Sponsor funded the initial principal amount of $450,000.

In connection with the closing of the transactions contemplated by the Investment Agreement, on January 26, 2023, the Former Sponsor underwent a reorganization pursuant to which the limited partners of the Former Sponsor transferred all of their limited partnership interests to Constellation Sponsor LP, a newly formed Delaware limited partnership (the "New Sponsor"). On January 26, 2023, the Former Sponsor was liquidated pursuant to applicable law by the retirement of the general partner of the Former Sponsor (the second to last partner of the Former Sponsor) and all securities held by the Former Sponsor were distributed by operation of law to its sole remaining limited partner, the New Sponsor, following which, on January 30, 2023, in connection with the closing of the Investment Agreement, control of the New Sponsor was transferred to affiliates of Antarctica Capital Partners, LLC, including Antarctica Endurance Manager, LLC.

However, certain of such shares are subject to certain lock-up restrictions as further described in Item 6 below. Except for the foregoing, the Reporting Persons have no plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) and (c) through (j) of Item 4 of Schedule 13D.

(c) Except as set forth in this Section 5(c), including the information set forth in Item 3 hereof, which is incorporated herein by reference, the Reporting Persons have not effected any transaction in Class A Shares during the past sixty days.

Notwithstanding the foregoing, the Letter Agreement provides exceptions pursuant to which the New Sponsor can transfer such shares to certain permitted transferees as further described in the Letter Agreement. Under the Letter Agreement, neither the Private Placement Warrants nor the shares underlying such warrants may be transferred (except to certain permitted transferees) until 30 days after the completion of the initial business combination;

(b) to not propose any amendment to the Issuer's amended and restated memorandum and articles of association that would (A) modify the substance or timing of the Issuer's obligation to redeem Class A Shares if the Issuer does not complete a business combination within the time period set forth in the Issuer's amended and restated memorandum and articles of association or (B) with respect to any other material provisions relating to shareholders' rights or pre-initial business combination activity, unless the Issuer provides its public shareholders with the opportunity to redeem their shares upon approval of any such amendment;

(c) to vote all shares owned by it in favor of any proposed business combination;

(d) to waive, with respect to any of the shares held by it, any redemption rights it may have in connection with (A) the consummation of a business transaction, including, without limitation, any such rights available in the context of a shareholder vote to approve such business transaction or in the context of a tender offer made by the Issuer to purchase the shares and (B) a shareholder vote to approve an amendment to the the Issuer's amended and restated memorandum and articles of association that would (Y) modify the substance or timing of the Issuer's obligation to redeem Class A Shares if the Issuer does not complete a business combination within the time period set forth in the Issuer's amended and restated memorandum and articles of association or (Z) with respect to any other material provisions relating to shareholders' rights or pre-initial business combination activity;

(e) to to waive, with respect to any of the Class B Shares held by it, any redemption rights it may have in connection with the liquidation of the Issuer if a business combination is not completed within the time period set forth in the Issuer's amended and restated memorandum and articles of association; and

(f) that in the event of the liquidation of the Trust Account of the Issuer (as defined in the Letter Agreement), it will indemnify and hold harmless the Issuer against any and all loss, liability, claims, damage and expense whatsoever which the Issuer may become subject as a result of any claim by any third party for services rendered or products sold to the Issuer, or by any prospective target business with which the Issuer has entered into a letter of intent, confidentiality or other similar agreement for a business combination, but only to the extent necessary to ensure that such claims do not reduce the amount of funds in the Trust Account to below (i) $10.00 per public share or (ii) such lesser amount per public share held in the trust account as of the date of the liquidation of the Trust Account, due to reductions in value of the trust assets, less taxes payable; provided that such indemnity shall not apply if such third party or prospective target business executes an agreement waiving any claims against the Trust Account.

This description of the Letter Agreement is qualified in its entirety by reference to the full text of such agreement, a copy of which is filed as an exhibit hereto.
