Background: As NASA plans for the retirement of the International Space Station at the end of the decade, the ability of private industry to take on the task of providing routine utilization of low-Earth orbit (LEO) and maintaining a continuous U.S. presence in space is of vital importance to both NASA and U.S. goals. In a multiphase strategy, the Lyndon B. Johnson Space Center's (JSC) Commercial Low-Earth Orbit Development Program (CLDP) is helping to spur the development of new low-Earth orbit space destinations and supporting systems from private industry. These systems may include end-to-end services such as the in-orbit destination, visiting vehicles, and supporting launch vehicles and ground systems. NASA is currently developing requirements for Commercial LEO Destination (CLD) capabilities to safely support operations of NASA astronauts and spaceflight participants in LEO on a commercially owned and operated space system. See the links here for additional information: https://www.nasa.gov/leo-economy/low-earth-orbit-economy/ and NASA's Low Earth Orbit Microgravity Strategy . Purpose: NASA's CLDP is providing an industry update per the attached presentation slides to communicate the CLD's Phase 2 acquisition strategy. Industry is invited to provide input in the form of written questions and/or comments to support NASA's evolving acquisition strategy and enable NASA…
