Solicitation Number: NNH20ZDA013L

NASA’s Science Mission Directorate seeks commercial and non-commercial organizations that may be interested in partnering with scientific instrument providers for the fabrication, assembly, and testing of scientific instruments for a potential Geospace Dynamics Constellation mission. NASA particularly encourages interested organizations that have expertise with the production of spaceflight instruments but that do not regularly engage with the heliophysics community to respond to the Request for Information: Partnering for Production of Spaceflight Scientific Instruments for Geospace Dynamics Constellation (GDC).


The GDC mission concept has a science focus on the coupled ionosphere-thermosphere system and is envisioned as a spacecraft constellation (6-12 observatories) orbiting Earth at an altitude of 350-400 km with orbital inclinations of >80 degrees. GDC’s science objectives and launch readiness date would require the production of flight units on a forward-leaning schedule and significant calibration efforts on the ground and in flight.


For science missions like GDC, NASA conducts an open competition for science investigations that include the delivery of flight hardware for accommodation on the spacecraft. NASA expects that the science community will be interested in proposing a combination of in situ instruments (e.g., neutral particle instrument, charged particle instrument, magnetometer) and remote sensing instruments (e.g., RF receivers, optical sensors, active sounders).

RFI responses must be submitted through the NASA Solicitation and Proposal Integrated Review and Evaluation System (NSPIRES). Information submitted via this RFI will be made public on the Science Office for Mission Assessment website (SOMA, at NASA Langley Research Center) for optional use by the science community planning for a potential GDC mission. The SOMA website may be found at
