About this opportunity

NASA intends to release a BAA under Next Space Technologies for Exploration Partnerships (NextSTEP-3), Appendix E, for Project NEXUS, Ka-band Backward- Compatible Relay. As the aging Tracking and Data Relay Satellite System (TDRSS) declines, NASA�s objective is to acquire an end-to-end Ka-band relay service, including space, ground, launch, integration, and operations elements, that is backward compatible with legacy TDRSS users for a minimum of fifteen years. This capability is needed to support select on-orbit missions that cannot feasibly modify flight hardware or transition to non-compatible commercial services. To reduce growing continuity risk in the 2029- 2031 timeframe, industry is asked to develop and demonstrate this end-to-end capability. The BAA will be a phased competitive Res...
