Laser Interferometer Space Antenna (LISA) Frequency Reference System (FRS) Flight RFP

Description: NASA's Goddard Space Flight Center issued an active presolicitation for the design, fabrication, qualification, and delivery of flight Frequency Reference System hardware for the LISA mission, comprising three flight models and one flight spare. Each unit combines an optical reference cavity and frequency-locking electronics, with deliveries scheduled between February 2029 and May 2030 and minimal post-delivery support. NASA intends to issue a sole-source contract to BAE Systems Space & Mission Systems Inc.; interested organizations may submit capability and qualification information by September 19, 2026, at 4:30 PM EDT, and this is a procurement notice rather than a grant.
