Mission Extension Vehicle

It's impossible to revive a satellite. Until it's not.

What is the Mission Extension Vehicle?

The Mission Extension Vehicle-1(MEV-1), the industry’s first satellite life extension vehicle, completed its first docking to a client satellite, Intelsat IS-901 on February 25, 2020. MEV is designed to dock to geostationary satellites whose fuel is nearly depleted. Once connected to its client satellite, MEV uses its own thrusters and fuel supply to extend the satellite’s lifetime. When the customer no longer desires MEV’s service, the spacecraft will undock and move on to the next client satellite.

The second Mission Extension Vehicle (MEV-2) launched August 15, 2020 along with the Northrop Grumman-built Galaxy 30 satellite. MEV-2 will dock with the Intelsat IS-1002 satellite in early 2021.
