Engineers and technicians install a 10-foot (3-meter) high-gain antenna on NASA's Europa Clipper spacecraft on Aug. 14, 2023. The orbiter is being assembled in the clean room of the High Bay 1 clean room of the Spacecraft Assembly Facility at the agency's Jet Propulsion Laboratory, in preparation for launch to Jupiter's moon Europa in October 2024. The precision-engineered dish was attached to the spacecraft in carefully choreographed stages over the course of several hours.

Europa Clipper will need the huge antenna to transmit data hundreds of millions of miles back to Earth. Scientists believe the icy moon Europa harbors a vast internal ocean that may have conditions suitable for supporting life. The spacecraft will fly by the moon about 50 times while its science instruments gather data on the moon's atmosphere, surface, and interior – information that will help scientists learn more about the ocean, the ice crust, and potential plumes that may be venting subsurface water into space.
