It landed at NASA’s Kennedy Space Center in Florida on Saturday, November 12th at 5:22AM ET, marking its sixth successful mission so far.While the agency is pretty tight-lipped as to what exactly the Boeing-built spaceplane does, it did reveal that it deployed the FalconSat-8 developed by the US Air Force Academy in October 2021.It hosted the Naval Research Laboratory’s photovoltaic radiofrequency antenna module as well, which is designed to convert solar rays into microwave energy and “transmit power to the ground.”The spaceplane, which looks like a smaller version of NASA’s Space Shuttle, first took flight in 2010, and we haven’t learned much about its purpose since.“Since the X-37B’s first launch in 2010, it has shattered records and provided our nation with an unrivaled capability to rapidly test and integrate new space technologies,” Jim Chilton, the senior vice president of Boeing Space and Launch said in a statement.“With the service module added, this was the most we’ve ever carried to orbit on the X-37B and we’re proud to have been able to prove out this new and flexible capability for the government and its industry partners.”"
