"NASA's $1 Billion Plan: Designing a Space-Tug to Retire and Bring Back the International Space Station"

NASA is seeking design proposals for a $1 billion space-tug, officially referred to as the U.S. Deorbit Vehicle, to safely take the aging International Space Station (ISS) out of orbit. The spacecraft will be focused on the final deorbit activity and must function on its first flight with redundancy and anomaly recovery capability. Industry members have until November 17 to submit their proposals. NASA plans to use commercial space stations for its low orbit efforts post-ISS.
