Network Extension for User Continuity and Sustainability (NEXUS) Ka-Band Backward-Compatible Relay Broad Agency Announcement (BAA) NextSTEP-3 Appendix E - Draft Solicitation

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 (end-to-end must include: space, ground, launch, integration, and operations elements) that i
