TSIS-2 / SSTP NRHO Demo Sources Sought

TSIS-2 / SSTP NRHO DEMO SOURCES SOUGHT The National Aeronautics and Space Administration (NASA) Kennedy Space Center (KSC) is hereby soliciting information about potential sources for dedicated or rideshare launch services for two separate potential missions: • Total Solar Irradiance Spectral Solar Irradiance 2 (TSIS-2). The TSIS-2 mission will provide absolute measurements of the total solar irradiance (TSI) and spectral solar irradiance (SSI), necessary for accurate scientific models of climate change and solar variability. • Small Spacecraft Technolog
