NASA's Glenn Research Center is seeking to extend the Space Flight Systems Development and Operations Contract II (SpaceDOC II) for an additional six months, through June 30, 2025. This extension is necessary to continue microgravity research investigations and support critical space flight technology developments while a follow-on contract, SpaceDOC III, is being finalized. The current contractor, ZIN Technologies, Inc., will be engaged on a sole source basis to ensure there is no interruption in mission-critical services and hardware delivery during this transition period. Interested organizations may submit their capabilities and qualifications statements to Matthew Evans at Matthew.T.Evans@nasa.gov by 5:00 PM ET on September 30, 2024, for consideration in this procurement process.
