- Submit an Organizational Conflict of Interest (OCI) plan; if an unresolved conflict exists, the offeror can be ineligible.

- List the prime and subcontractors and which parts of the statement of work (SOW) each will do. NASA uses this to judge past performance and to check whether the Small Business Administration (SBA) must rule on size and that the prime does the primary and vital work.
- Provide financial capability disclosure information showing you can do the work at the fixed prices in Section B.
- Have a Commercial and Government Entity (CAGE) code that matches the corporate address submitted with the proposal.
How to submit: NASA's Enterprise File Sharing and Sync Box (EFSS Box), a government-approved cloud file-sharing site. What to include is under Full summary below. Check the solicitation's instructions on SAM.gov.
Things to watch (11)
From the version posted Oct 15, 2026.
- Serious: Eligibility checks can make a firm ineligible. NASA checks the OCI plan, prime and subcontractor listing, Domestic Source Certification and financial capability, and an offeror that can't make them acceptable is ineligible for award.
- Serious: Only one provider continues past CLIN 1. A contract line item number (CLIN) is one priced line of the order. NASA plans two CLIN 1 awards at contract award but one CLIN 2 award after CLIN 1, and CLIN 4 orders are open to CLIN 1 awardees; all proposals are due on the response due date.
- Serious: End-to-end station and transportation pricing. Offers must price the whole service, including crew and cargo transport, so a small business needs a team that covers station, launch and return vehicles.
Show all 11Show fewer
- Worth checking: Very large contract. The Government's maximum is $34.063B, and the work covers building and certifying a crewed space station.
- Worth checking: Past performance volume requested early. Volume III, Past Performance, is requested on November 24, 2026, before the response due date, and your references need to send their information before then too.
- Worth checking: Government Task Agreement requests due October 31, 2026. To use NASA facilities or services, send a Government Task Agreement (GTA) request by October 31, 2026; NASA returns completed GTAs no later than December 1, 2026.
- Worth checking: Team members with $100 million of work count for past performance. Subcontractors and suppliers expected to do $100 million or more of work during the 8-year base period are treated as major team members in the past performance volume.
- Worth checking: Model contract errors can remove an offer. Mistakes or gaps in the Volume V Model Contract can take an offeror out of consideration.
- Worth checking: Launch vehicle insurance amount. The Final RFP lowers Launch Vehicle Category 2 insurance to $200M from $500M in the draft; other insurance amounts were not read.
- Minor: Rated order under the Defense Priorities and Allocations System. The Defense Priorities and Allocations System (DPAS) rating of DO-C9 means the contract must be given priority over unrated orders.
- Minor: Questions were due Oct 21, 2026. Check the amendments for the agency's answers.
