OSAM-1 (On-orbit Servicing, Assembly, and Manufacturing 1) is a US NASA spacecraft designed to test on-orbit refilling of satellites. It was previously known as Restore-L. Originally planned for 2020, its launch is currently planned for no earlier than 2025. Its first objective would be the complex refueling of Landsat 7, an existing satellite launched in 1999. It would involve grasping the satellite with a mechanical arm, gaining access to the satellite's fuel tank by cutting through insulation and wires and unscrewing a bolt, and then attaching a hose to pump in hydrazine fuel. This would be the first refueling of a satellite in space, and a demonstration of the potential to repair the thousands of satellites in orbit and keep them in operation. Because the satellites now in space were n
