December 2, 2022 NASA Delivers First Flight Hardware to ESA for Lunar Pathfinder 12/02/2022 NASA delivered the first flight hardware for the Lunar Pathfinder mission to ESA (European Space Agency), which formally accepted the instrument on Nov. 4. NASA's Goddard Space Flight Center in Greenbelt, Maryland, developed the instrument, a laser retroreflector array, which will test new navigation techniques for lunar missions. NASA and ESA plan to launch Lunar Pathfinder via a future Commercial Lunar Payload Services delivery. In addition to testing navigation capabilities, Lunar Pathfinder will operate as a commercial communications relay satellite and provide communications services for exploration missions on the lunar surface. The Lunar Pathfinder mission is led by Surrey Satellite Technology Ltd (SSTL), and ESA arranged for the mission to provide communications services to NASA. NASA Space Geodesy Project Manager Stephen Merkowitz, along with teams from ESA and SSTL, completed inspections when the laser retroreflector array arrived at SSTL's facility in Guildford, U.K., where it will be installed in the satellite.
