Draft RFP - Near Earth Orbit Network Program's Sounder for Microwave-Based Applications

THIS IS NOT A REQUEST FOR PROPOSAL. NO PROPOSALS ARE TO BE SUBMITTED IN RESPONSE TO THIS NOTICE.

This notice is issued by the NASA/GSFC to post a Draft RFP to solicit responses from interested parties. This document is for information and planning purposes and to allow industry the opportunity to verify reasonableness and feasibility of the requirement, as well as promote competition.

This Draft RFP is for the Sounder for Microwave-Based Applications (SMBA) requirement. The principal purpose of this requirement is to design, develop, and support the SMBA instruments under the Near Earth Orbit Network (NEON) program.

This presolicitation synopsis is not to be construed as a commitment by the Government, nor will the Government pay for the information submitted in response. The Government may not respond to questions/concerns submitted. The Government will use the information to finalize the RFP as necessary.

All comments or questions shall be submitted electronically via email to Bruce Tsai at Bruce.B.Tsai@nasa.gov no later than 5:00 PM Eastern Time on May 9, 2025. When responding, reference DRFP-NEON-SMBA-2025.

NASA Clause 1852.215-84, Ombudsman, is applicable. The Center Ombudsman for this acquisition can be found at: https://www.hq.nasa.gov/office/procurement/regs/Procurement-Ombuds-Comp-Advocate-Listing.pdf

If a solicitation is released, then it and any additional documents will be available on Sam.gov. It is the offeror's responsibility to monitor this website for the release of the solicitation and amendments (if any). Potential offerors will be responsible for downloading their own copy of the solicitation and amendments, if any.

NASA intends to publicize a listing of respondents to facilitate teaming arrangements. Should your firm desire not to be included in this listing, clearly indicate this desire in your response.

Amendment 1: Virtual Industry Day - Please refer to the document entitled, "Post-DRFP Industry Day.pdf" for instructions

Amendment 2:  1. Attach "SMBA Post-DRFP Industry Day Slides.pdf"; 2. Update the planned release timeframe for the final Request for Proposal to Calendar Year 2025, Quarter 4; and 3.

Amendment 11: 

The National Environmental Satellite, Data, and Information Service (NESDIS) perspective on the go-forward is the following:

1. Multi-phase, Multi-select Acquisition
2. Phase 1
   • Number of contractors: Up to two contractors
   • Period of Performance: Through Engineering Test Unit (ETU) development and environmental testing
   • Scope: Includes long lead items for ETU and Flight Models 1-4; and all associated reviews through Contract Data Requirements List (CDRL) item RE-13: ETU Test Summary Review Package delivery
   • Contract Type: Cost Reimbursement
3. Down-Select for Phase 2
   • Point in time: Occurs at approximately contract authorization to proceed (ATP) plus two years
   •  Evaluation Criteria: Will include Critical Design Review (CDR) package, ETU test data, forward plans, and other related items. However, these evaluation factors are not final and NASA reserves the right to change them at any time, up to and including the date upon which Phase 2 proposals are requested.
4. Phase 2
   • Number of contractors: one contractor
   • Period of Performance: Flight Model 1 forward
   • Contract Type: Fixed Price

The Government procurement team will proceed with this go-forward plan while the leadership chain is briefed. The go-forward plan may change during this process. Changes to the go-forward plan (if any) or contract documents will be posted as soon as they are available.

2. Phase 1
   • Number of contractors: Up to two contractors
   • Period of Performance: Through Engineering Test Unit (ETU) development and environmental testing
   • Scope: Includes long lead items for ETU and Flight Models 1-4; and all associated reviews through Contract Data Requirements List (CDRL) item RE-13: ETU Test Summary Review Package delivery
   • Contract Type: Cost Reimbursement
3. Down-Select for Phase 2
   • Point in time: Occurs at approximately contract authorization to proceed (ATP) plus two years
   •  Evaluation Criteria: Will include Critical Design Review (CDR) package, ETU test data, forward plans, and other related items. However, these evaluation factors are not final and NASA reserves the right to change them at any time, up to and including the date upon which Phase 2 proposals are requested.
4. Phase 2
   • Number of contractors: one contractor
   • Period of Performance: Flight Model 1 forward
   • Contract Type: Fixed Price
