OFFICIAL NOTICE CONTENT

Opportunity description

Stored from SAM.gov public data

UPDATE #1 � Amendment #0001 to the RFP was released on October 22, 2026. UPDATE #2 � Amendment #0002 to the RFP was released on October 26, 2026. The National Aeronautics and Space Administration (NASA), Goddard Space Flight Center (GSFC), hereby invites interested parties to review the Final Request for Proposal (FRFP) for the Hydrosphere, Biosphere, and Geophysics (HBG) Support Services II requirement supporting the Earth Sciences Division (ESD) at NASA/GSFC. The principal purpose of this requirement is to provide science research that conceives, develops, and applies space, field-deployed (i.e. airborne and in situ) and laboratory based technologies and observations to address issues of importance to society. These include but are not limited to water resources, land and ocean ecosystems, global and regional sea level change, changes in the Earth�s cryosphere, gravity field, magnetic field, solid Earth, and the terrestrial reference frame. The Statement of Work, Attachment A, describes the scope of the requirement. This contract is for support of a full range of science and research activities across the breadth of the various Laboratories that make up the HBG sub-division: the Cryospheric Sciences, Ocean Ecology, Hydrological Sciences, Biospheric Sciences, and Geodesy and Geophysics Laboratories. This contract is also for support of science, research and computing activities within the Terrestrial Information Systems Laboratory (TISL), also in the ESD. For the purposes of this document and contract the term HBG will be used to encompass all the Laboratories of the HBG sub-division and the TISL. NASA will conduct this acquisition as a small business set-aside. This competitive acquisition was originally contemplated as a Cost-Plus-Fixed-Fee (CPFF), Indefinite-Delivery/Indefinite-Quantity (IDIQ) contract with the ability to issue CPFF task orders. Following further acquisition planning and assessment of the Government's requirements, the contract structure has been modified. The HBG II Draft Request for Proposal (DRFP) posted on April 8, 2025 was issued as an IDIQ CPFF solicitation. As amended, this competitive acquisition will now result in a HYBRID Indefinite Delivery Indefinite Quantity (IDIQ) with the ability to issue Cost Plus Fixed Fee (CPFF) AND Firm- Fixed Price (FFP) task orders. The contract will have an effective ordering period of five years from the contract effective date. Interested offerors are encouraged to review the solicitation and all associated attachments for complete details regarding the requirements and proposal submission instructions. Please see the attached cover letter for additional information.

GOVBIDFIT SCREENING LENS

What deserves attention before you spend bid time

Decision support

These screening signals are generated from the public notice fields stored for this specific opportunity. They are not eligibility findings or predictions; they are prompts for a faster, more disciplined review of the official solicitation.

Active solicitation stage

This record is in a solicitation stage, so submission instructions, evaluation factors, attachments and amendments should be reviewed before a bid/no-bid decision.

Planning window available

The stored response date leaves more than ten days, but amendments and pre-response milestones can shorten the usable preparation window.

No socioeconomic restriction recorded

The current feed does not show a program-specific set-aside restriction. That does not remove other eligibility, responsibility, registration or solicitation-specific requirements.

Classification signal

NAICS 541715 · PSC AJ11 is the recorded classification. Use it as a screening clue, then compare the actual scope and deliverables rather than treating the code alone as proof of fit.

Notice history exists

GovBidFit stores 3 notices tied to this solicitation. Review the notice chain and official SAM.gov history because later postings can change dates, scope or instructions.

Official description stored

GovBidFit stores the source notice text, but its length does not prove the requirements are complete. Review official attachments, clauses, amendments and Q&A before relying on the description.

Public buyer contact available

The source data includes 2 public contracting contacts. Use the solicitation's stated communication rules and deadlines before contacting the buyer.

What this opportunity record tells you

SAM.gov identifies this as a solicitation from NATIONAL AERONAUTICS AND SPACE ADMINISTRATION. The record was posted on October 26, 2026 and currently lists December 4, 2026 as the response deadline.

The listed product or service classification is NAICS 541715 · Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) · PSC AJ11. The set-aside field is Unrestricted. These fields help narrow your search, but they do not replace the full solicitation, amendments, attachments, clauses or eligibility language on the official source.

Before deciding to bid

Read the complete official description and scope. Verify the exact response date, time and time zone on SAM.gov. Confirm NAICS/PSC and every set-aside eligibility requirement. Review attachments, amendments, Q&A and submission instructions. Check place of performance, staffing, insurance, bonding and execution requirements.
