About this opportunity
NASA Goddard Space Center seeks industry information on capabilities, interest, and options for a Phase A study of the Geostationary extReme UltraViolet Imager (GRUVI), a solar observing instrument for a future NOAA space weather mission, with responses due December 3, 2026. No set-aside is used. The notice is a Request for Information, not a request for proposals, and no proposals are to be submitted.
The government anticipates multiple awards for the Formulation/Risk reduction phase. The Phase A study runs nine months from kickoff, with kickoff within two weeks of award, a midterm review at 4.5 months, a final study review at 8.5 months, and final report delivery at nine months. The government plans a fixed-price contract and may authorize priced or unpriced options to add scope. The SOW describes a contractor-proposed pre-priced option for six additional months of study. Following Phase A, the government anticipates moving directly to a System Requirements Review about one month after Implementation contract award, targeted for Q4 FY 28, with flight hardware delivery and Pre-Ship Review in Q4 FY 31 and launch readiness in Q3 FY 32. The RFI also assesses contractor capability to manufacture the instrument. The government states that the required capabilities are not currently within the NASA/NOAA workforce and plans to identify them in house in the future.
The sensor must resolve coronal holes, filaments, prominences, active regions, coronal mass ejections, and X10 Class solar flares for National Weather Service and NOAA Space Weather Prediction Center forecasts. The draft requirements specification cites scene coverage from 0 to 1.5 solar radii, spatial resolution of 5 arcseconds or better, a 39.4 kg mass limit, a 25 cm envelope per axis, SpaceWire interface with CCSDS packet protocols, and 2.5 arcsecond pointing knowledge at 3-sigma. The specification contains numerous TBD and TBR values. The study assumes one Engineering Development Unit, one flight unit, no Government-furnished equipment, and a Class C sensor classification. The requirement for the number of spectral bands is open, and bands will be selected for sensitivity to different plasma temperatures.
Notice text
THIS IS NOT A REQUEST FOR PROPOSAL. NO PROPOSALS ARE TO BE SUBMITTED IN RESPONSE TO THIS NOTICE.
This RFI seeks information from industry regarding capabilities, interest, and options for providing a solar observing Space Weather (SW) Next Geostationary extReme UltraViolet Imager (GRUVI) Instrument for a future operational NOAA Space weather mission that can resolve solar features, including coronal holes, filaments and prominences, active regions, coronal mass ejections (CMEs), and X10 Class solar flares which will be used by the National Weather Service and the NOAA Space Weather Predication Center to generate and provide Space Weather forecasts and alerts. Solar GRUVI imagery will provide comprehensive situational awareness of the inner solar corona. Although there is no requirement for the number of GRUVI spectral bands, bands will be selected that are sensitive to different plasma temperatures within the range specified for feature and phenomenological discrimination. It is anticipated that at the conclusion of this Phase A study any industry partner will be prepared to enter directly into a System Requirements Review (SRR), approximately one month after Implementation contract award, followed by a Preliminary Design Review (PDR).
The capabilities required to perform this Phase A Study for the GRUVI instrument are not currently within the NASA/NOAA workforce, thus the government requires contractor support to perform this study. It is the plan that in the future the capabilities being sought by the RFI will be identified in house, which would allow the government to leverage using our own work force. In addition this RFI will allow the Government to assess contractor capability to manufacture the GRUVI instrument.
The Government anticipates multiple awards for the Formulation/Risk reduction phase of the contract. Further, since this is planned to be a fixed price contract the government may authorize the use of priced, or unpriced option to add additional scope or extend the period of performance should the RFI result in the formation of the contract for the GRUVI instrument. The only unique attribute is that the Government will consider a pre-priced option proposed by a contractor to retire additional implementation risk.
All responses, comments and/or questions shall be submitted electronically via email to Kelly Lytton at kelly.r.lytton@nasa.gov no later than 5:00pm EDT December 3, 2026.
