Landsat 7

NASA plans the On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1) mission in 2025 to robotically refuel Landsat 7, a satellite that was not designed to be serviced.

Landsat 9 replaces Landsat 7, which was launched in 1999.

Landsat 7, launched in 1999, remains in limited service.

NASA and Maxar Technologies are developing the On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1) mission to robotically refuel the Landsat 7 imaging satellite.

Thermal infrared data is currently rare and is provided only by a few institutional satellites such as Sentinel-3 and Landsat 7/8.

Maxar is building the OSAM-1 satellite to rendezvous with the Landsat 7 spacecraft and refuel it before conducting a series of in-space robotic assembly demonstrations including SPIDER.

OSAM-1 is scheduled for launch in 2024 using a commercial satellite bus provided by Maxar and will rendezvous with and refuel the Landsat 7 spacecraft while demonstrating in-space robotic assembly of an antenna and a boom.

Restore-L’s primary mission is to refuel Landsat 7, an Earth observation satellite launched into a sun-synchronous orbit in April 1999.

NASA’s Restore-L satellite servicing program is being developed by Maxar under a NASA contract to demonstrate refueling of legacy satellites using Landsat-7 as the planned target.

Restore-L will have residual capability after completing its Landsat-7 demonstration, and NASA will determine if and how that residual capability is used.

Maxar is working with NASA on Restore-L, a satellite servicing project scheduled to launch in 2022 to demonstrate refueling of the 20-year-old Landsat-7 satellite.

NASA plans to use Restore-L, based on the SSL-1300 bus, to refuel the almost 20-year-old Landsat-7 satellite.

SSL is working with NASA’s Goddard Space Flight Center to refuel the Landsat 7 Earth-observation satellite.
