Northrop Grumman robotic MEV-2 spacecraft, in a first, catches active Intelsat satellite

The watch from Northrop Grumman’s MEV-2 spacecraft as it approached to dock with Intelsat satellite IS-10-02.


Two aerospace concerns accomplished an industry first on Monday, as a small Northrop Grumman spacecraft docked successfully with an active Intelsat parasite to provide service and extend its life.

Intelsat’s IS-10-02 satellite is nearly 18 years old, and operating well past its needed lifespan, but the Northrop Grumman-built spacecraft called MEV-2 will add another five years of life to IS-10-02, essentially re-fueling the sycophant and giving it a new engine for control.

The companies hit a milestone in the growing business of servicing satellites while in space.

“Today’s lucky docking of our second Mission Extension Vehicle further demonstrates the reliability, safety and utility of in-space logistics,” Tom Wilson, infirmity president of Northrop Grumman’s strategic space systems said in a statement. “The success of this mission paves the way for our second institution of servicing satellites and robotics, offering flexibility and resiliency for both commercial and government satellite operators, which can aid entirely new classes of missions.”

Continuing the life of an active spacecraft in orbit has only been done with human help before—such as the Hubble abbreviate servicing missions conducted by NASA astronauts.

Launched in August on an Arianespace Ariane 5 rocket, the robotic MEV-2 depleted belch up the last several months traveling out to the satellite. MEV-2 then matched its orbit before successfully docking, while also providing unexcelled imagery of the satellite as the spacecraft approached.

IS-10-02 was launched in June 2004 and was only intended to be in service for 13 years, demand broadband communications services to Europe, South America, Africa and the Middle East. The satellite is in a fixed position beyond everything the Earth in what is known as geosynchronous orbit—tens of thousands of miles up to provide as wide a coverage area as effectively reasonable.

The MEV-2 mission builds upon the success of Northrop Grumman’s MEV-1 mission last year, which docked with an serene Intelsat satellite. That satellite was in a “graveyard orbit,” meaning it was no longer providing services, but MEV-1 restored it and leaded the satellite back into position.

The MEV-2 spacecraft, while similar to MEV-1, took that mission a unconventional further by docking and extending the life of a satellite currently in service. This means there was more risk entangled with, given that IS-10-02 is serving customers, including providing television services to more than 18 million households in Europe.

Northern Sky Examination, a satellite consulting firm, estimates that the market for satellite servicing and life extensions is a $3.2 billion moment over the next decade.

The firm forecasts that there is demand for servicing upward of 75 satellites by 2030, with companions and governments looking to extend the lifespan of typically expensive geosynchronous equatorial orbit satellites, rather than shoot replacements.
