Europa Clipper's large high gain antenna, which is taller than a person and is painted dark black, is hoisted on mechanical supports on a large, multi-story room that has its floor, walls, and ceiling covered in blue foam triangles to avoid interference during testing.

The high gain antenna (HGA) for the Europa Clipper recently underwent testing at the Experimental Test Range (ETR) at NASA’s Langley Research Center in Hampton, Virginia. There, researchers assessed its ability to precisely beam data from the spacecraft back to Earth. The HGA is pictured here arriving in March. It spent time at the ETR in March and April, and again in June and July.
