NExIS
NASA’s Exploration & In-space Services (NExIS) is ushering in an era of more sustainable, affordable and resilient spaceflight near Earth, the Moon and deep into the solar system through in-space servicing and assembly.
In-Space Servicing, Assembly, and Manufacturing
Robots are poised to make what was once thought to be impossible in space a reality. The In-Space Servicing, Assembly, and Manufacturing (ISAM) is extending the lifespan of satellites, to assembling massive life-seeking telescopes in space, to refueling and repairing spacecraft on journeys to distant locations, the possibilities are endless.
