Space weather Observations at L1 (SOL) Series X-ray Irradiance Sensor (XRIS)

Pre-Solicitation Notice for Space weather Observations at Lagrange 1 (SOL) X-ray Irradiance Sensor (XRIS)

The National Aeronautics and Space Administration (NASA)/Goddard Space Flight Center (GSFC) and National Oceanic and Atmospheric Administration (NOAA) plan to issue a Draft Request for Proposal (RFP) for the Space weather Observations at Lagrange 1 (SOL) X-Ray Irradiance Sensor (XRIS) instrument.

SOL is a high priority joint undertaking by NASA and NOAA. Two SOL Observatories will provide NOAA with the continuity of solar wind data, Coronal Mass Ejection (CME) imagery, and the second observatory will provide X-ray irradiance data from the XRIS instrument.
