SpaceX is scheduled to launch a satellite servicing spacecraft to Earth orbit today on the MRV-MEP mission. The vehicle is designed to use robotic arms to help support satellites already operating in space, marking another step in efforts to make satellite fleets last longer.

According to the mission description, the MRV-MEP spacecraft is intended to extend the operational lives of multiple satellites in geostationary orbit. That region is home to many communications and other long-duration spacecraft, so a servicing mission like this could help operators get more use from satellites that are already in place.

The launch is drawing attention because it highlights a growing focus on in-orbit servicing rather than replacing satellites as soon as they near the end of their planned missions. A robotic platform capable of working with several spacecraft could become an important tool for managing valuable hardware in geostationary orbit.

People interested in the mission can follow the launch through live coverage associated with the event. With the spotlight on SpaceX and the MRV-MEP spacecraft, today’s flight is expected to be closely watched by those tracking satellite servicing and orbital technology.
