OSAM-1, short for On-orbit Servicing, Assembly, and Manufacturing 1, was a NASA technology demonstration spacecraft meant to refuel a satellite that was never designed to be serviced in orbit. Managed by the Goddard Space Flight Center, it was to rendezvous with, grapple and berth the government-owned Landsat 7 and then use a suite of tools to replenish that satellite's hydrazine fuel tank. The spacecraft was built around a bus that Maxar supplied, and Maxar also provided the SPIDER payload, a robotic arm system meant to assemble a Ka-band antenna in orbit from stowed hexagonal pieces. The bus left a Maxar facility in California and reached Goddard in Greenbelt, Maryland on 20 September 2023 so that engineers could integrate the payload and test the spacecraft. NASA announced the cancellation of the mission on 1 March 2024 because of technical, cost and schedule challenges and began an orderly shutdown, so the spacecraft never launched. The project was first known as Restore-L.
