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.
The X-ray Irradiance Sensor (XRIS) instrument will be used to measure the energy power from solar radiation per unit area to detect changes in solar activity, like solar flares, and help predict solar energetic particle events that can penetrate the Earth-s magnetic field. The instrument will monitor X-ray flares that can cause changes in the Earth-s ionosphere such as strong radio bursts that may interfere with radio frequencies and cause problems for satellite communication and navigation systems. Coronal Mass Ejections (CMEs) are sometimes associated with solar flares which can lead to geomagnetic storms.
SOL will procure one (1) flight and one (1) spare XRIS instrument that will provide NOAA with the continuity and resilience of space weather observations for the X-ray irradiance. The X-ray irradiance measurement is a high availability (HAP) product, which is one of the National Weather Service-s highest priorities for space weather observations. The continuation of these observations is essential for space weather predictions and the creation of actionable warnings for the protection of critical infrastructure that includes different sectors in the nation like aviation, commerce, energy, space exploration, and defense. XRIS will fly on the second observatory, SOL-B, which is... - Documents:
