STP-2 NASA Tech Show

Jill Seubert, deputy principal investigator, from NASA’s Jet Propulsion Laboratory in Pasadena, California, explains the payload during a NASA prelaunch technology TV broadcast for the Space Test Program-2 (STP-2) mission at the agency’s Kennedy Space Center in Florida on June 23, 2019. The new space clock could improve how we navigate on the Moon, to Mars and beyond. The space clock is one of four NASA payloads scheduled to launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A beginning at 11:30 p.m. EDT on June 24, 2019. STP-2 is managed by the U.S. Air Force Space and Missile Systems Center.
