Refueling demonstration missions

Refueling demonstration missions test and showcase the process of transferring fuel from one spacecraft to another in space. These missions validate techniques and equipment needed for in-orbit refueling, which extends the lifespan of satellites and spacecraft. During the mission, a tanker spacecraft approaches and connects with a target satellite or spacecraft, transferring fuel while both are in orbit. Successfully demonstrating this capability helps ensure safe, efficient, and reliable refueling operations in future space missions, reducing the need for satellite replacement and enabling more sustainable space exploration and operations.
