Current obstacles

Satellite compatibilityNot all satellites were designed for on-orbit servicing; older designs may not have compatible interfaces.
Cost recoveryServicing must be cheaper than launching new satellites; satellite operators must value life extension sufficiently.

Physics limits

Orbital mechanicsSpacecraft can only operate in accessible orbits; geosynchronous orbit is expensive to reach and requires precise approach and docking.
Thermal constraintsMechanical systems operating in vacuum face extreme temperature variations and outgassing challenges that affect reliability.

How it works

3 parts

Life extension

Fuel transfer and station-keeping

MEVs dock with satellites running low on propellant and use their own thrusters to extend operational life by 5+ years.

Robotic servicing

MRV advanced repairs

The MRV carries a multi-degree-of-freedom arm for inspection, repair, equipment replacement and satellite repositioning.

Debris removal

On-orbit cleanup

The system can grapple and deorbit defunct satellites and debris, reducing collision risk in crowded orbital regions.

About Northrop Grumman

The team behind Mission Extension Vehicles / Mission Robotic Vehicle

Northrop Grumman

YFQ-48A CCA drone, Cygnus resupply, satellite servicing

Northrop Grumman builds defense and space systems: Cygnus cargo resupply for the ISS, the YFQ-48A fighter drone for the USAF, and on-orbit satellite servicing via MEV and MRV spacecraft.

Cygnus XL resupply missions to ISS carry 5 tonnes per flight; 33% more capacity than standard Cygnus.
Mission Robotic Vehicle launched July 2026 with a seven-DOF arm for satellite servicing and debris removal.
YFQ-48A Talon autonomous fighter drone is a CCA contender with 30% faster assembly; first flight Q4 2026.
