Northrop Grumman launches robotic spacecraft for satellite servicing missions

The MRV and three Mission Extension Pods (MEPs) launched as part of Northrop Grumman’s effort to expand satellite servicing capabilities and enable additional in-space operations. The spacecraft incorporates robotic systems developed through a partnership with the Defense Advanced Research Projects Agency (DARPA) and the U.S. Naval Research Laboratory.

Key Highlights

  • The MRV features two articulated robotic arms and specialized tools for comprehensive satellite servicing tasks.
  • It includes Mission Extension Pods (MEPs) for propulsion augmentation, extending satellite operational life and maneuverability.
  • The spacecraft supports future on-orbit refueling with its Passive Refueling Module (PRM), enabling additional mission capabilities.

CAPE CANAVERAL, Fla. - Northrop Grumman has launched its Mission Robotic Vehicle (MRV), an autonomous spacecraft designed to perform on-orbit satellite servicing, inspection, relocation, repair, upgrades, and life-extension missions.

The spacecraft builds on Northrop Grumman’s experience with Mission Extension Vehicles (MEVs), which have provided satellite life-extension services for commercial communications spacecraft in geosynchronous orbit. The company’s two MEVs have docked with three commercial communications satellites and provided more than 10 years of combined mission extension services.

MRV background

The MRV uses rendezvous, proximity operations, and docking technologies to approach and connect with client satellites. The spacecraft is designed for servicing missions in geosynchronous orbit, where many commercial and government communications satellites operate.

The three MEPs launched with the MRV are designed for installation on client satellites, where they will provide propulsion augmentation to extend spacecraft operational life and enable additional maneuvering capability. The smaller-form-factor modules build on MEV technology and are intended to provide a lower-cost life-extension option for a broader range of spacecraft.

The spacecraft also carries the Passive Refueling Module (PRM), a Space Force-approved refueling interface standard designed to enable future on-orbit refueling operations. The capability could allow future servicing spacecraft to receive propellant in orbit and perform additional maneuvering missions.

The MRV includes onboard processing capabilities intended to support future advanced autonomy and artificial intelligence-enabled operations. The system is designed to provide additional flexibility for future robotic servicing missions as autonomous spacecraft technologies mature.

Northrop Grumman developed mission-enabling thermal control products and electronics used to support MRV operations, including systems that control the spacecraft’s robotic arms and electric propulsion thruster units.

On-orbit servicing capabilities are becoming an area of interest for commercial and defense space organizations seeking to extend spacecraft lifetimes, improve operational flexibility, and reduce dependence on replacing satellites at the end of their missions.
