NASA Langley Research Center requires continued on-orbit operations for the TEMPO Instrument as a hosted payload on an Intelsat IS-40e spacecraft at 91W longitude, including command relay, data delivery, and end-of-life deactivation. The host contractor must operate the geostationary spacecraft, monitor health and safety, and provide ephemeris data while meeting orbital debris disposal requirements. The government intends to issue a sole source contract to SES Space and Defense, which currently owns and operates the host satellite and ground stations, as no other company is permitted to send commands or decode the data downlink. No budget amount or submission timeline is specified in the description. The location for performance is on-orbit at 91W longitude, with ground stations owned by SES Space and Defense.
