European Space Agency proposes lunar satellites

BERLIN — The European Space Agency presented a vision Thursday to put satellites in orbit around the moon that would facilitate future missions to Earth’s closest neighbor.

The plan, dubbed “Moonlight,” would see ESA offer communications and navigation services to any country that wants to carry out lunar exploration missions.

By relying on services provided from lunar orbit, space agencies would be able to design their moon landers without the need for cumbersome communications and navigation devices on board. This would free up space to carry other cargo, making each launch more cost effective, said Paul Verhoef, ESA’s director of navigation.

The project builds on one of the agency’s strengths: launching satellites to provide services to third parties. ESA has a fleet of observation satellites in orbit around Earth that supply weather, climate and other data to public and commercial companies.

It also has a constellation of navigation satellites, known as Galileo, that provide highly accurate global positioning data to rival the U.S.-based GPS system.

But it also highlights the European agency’s weakness: ESA lacks any ambitious moon exploration programs of its own.
