Behind the Scenes: DART High Gain Antenna

(feat. Matthew Bray)

Building a spacecraft requires the coordinated efforts of various teams and individuals who all play an important role in getting a mission off the ground. As NASA's Double Asteroid Redirection Test (DART) undergoes integration and testing at the Johns Hopkins Applied Physics Lab (APL) in Laurel, Maryland, hear from various team members with diverse roles on the first ever planetary defense test mission.

Matthew Bray is the designer and lead engineer for the DART High Gain Antenna (HGA), following the antenna from concept to prototype, flight fabrication, and testing. The DART HGA is a wideband Radial Line Slot Array (RLSA) that forms a narrow beam, allowing high throughput images to be downloaded from DART's DRACO instrument as the spacecraft approaches the Didymos asteroid system. Watch Matthew and his team install the HGA onto the DART spacecraft.
