NASA Goddard Space Flight Center is running a Sources Sought / RFI (a request for information, not a solicitation) for GSMO-4, the follow-on to its Goddard Space Mission Operations contract that runs ground systems and mission operations for NASA science missions. NASA wants vendor approaches and rough-order-of-magnitude costs, and is asking about moving from cost-plus-award-fee to firm-fixed-price. Responses are due 2026-10-26.
Watch out for
- Very large, multi-mission scope. The work covers many major NASA missions end to end, so a small business would likely need to partner or respond for a limited scope.
- RFI only, no award. This is market research; responding takes effort and does not obligate NASA or guarantee a solicitation.
it does not obligate the Government in any way
- No cost reimbursement for responding. You pay for your own response, including a 30-page paper with cost estimates.
The Government will not reimburse respondents for any costs associated with responding to this request.
- Q&A sessions favor full-scope vendors. One-on-one Q&A sessions are planned only for vendors who can deliver the full contract scope.
