Intelsat partnered with Northrop Grumman on a second mission in 2021, using MEV-2 to extend the life of Intelsat 10-02.
Intelsat has become the first and only satellite operator to complete a satellite life-extension mission. The Mission Extension Vehicle (MEV) added five years of reliable service and global connectivity to the Intelsat 901 (IS-901) satellite and its customers.
Jean-Luc Froeliger, SVP of Space Systems, Intelsat, said: “The MEV mission proved that in-orbit servicing enhances satellite sustainability and efficiency in space. We were able to provide five additional years of reliable service to our Network, Media and Mobility customers and paved the way for future advancements in satellite servicing.”
The worlds first MEV, developed by Northrop Grumman Corporations Space Logistics LLC, successfully detached from IS-901 after moving the satellite to the graveyard orbit, where the satellite will be decommissioned after nearly 24 years of service. The MEV first docked with IS-901 in February of 2020 nearly 19 years after the satellite was first launched.
Geostationary satellites use propellant to remain at a specific orbital location, relocate to a new location or eventually be moved to a graveyard orbit. The MEV has its own propellant and thrusters that operate independently of the satellite. Through in-orbit docking, the MEV allows Intelsat to extend the life of a satellite by several years when the original propellant of that satellite has been depleted.
Froeliger added: “Using the MEV to extend the life of IS-901 was a great commercial success for our customers, as well as a historic technical achievement. We had to do a rendezvous and approach of two spacecraft moving at 3km per second.”
Following this success, Intelsat partnered with Northrop Grumman on a second mission in 2021, using MEV-2 to extend the life of Intelsat 10-02, a combination that remains operational today. Intelsat continues to seek out and invest in next-generation satellite life-extension projects and other innovation setting the stage for continued advancements and enabling emerging space companies to shape the future of the industry.
