CAPE CANAVERAL AIR FORCE STATION, Fla. (ULA PR) — The United Launch Alliance (ULA) Atlas V551 rocket carrying the Lockheed Martin-built Advanced Extremely High Frequency 5 (AEHF-5) satellite for the U.S. Air Force Space and Missile Systems Center is delayed, due to an anomaly during component testing at a supplier which has created a cross-over concern. 

Additional time is needed for the team to review the component anomaly and determine if any corrective action is required to the launch vehicle. Launch of the AEHF-5 mission is now targeted for no earlier than Thursday, Aug. 8, 2019.

AEHF satellites provide highly-secure, jam-proof connectivity between U.S. national leadership and deployed military forces. Atlas V rockets successfully launched the first four AEHF satellites in 2010, 2012, 2013 and 2018.

The AEHF-5 launch will mark the 80th Atlas V mission since the inaugural launch in 2002 and the 10th in the 551 configuration. The rocket features a kerosene-fueled common core booster, five solid rocket boosters, the hydrogen-fueled Centaur upper stage and a five-meter-diameter payload fairing.

The ULA Delta IV rocket carrying the GPS III SV02 mission for the U.S. Air Force Space and Missile Systems Center is delayed, due to an anomaly during component testing at a supplier which has created a cross-over concern. 

Upon further evaluation, additional time is needed to replace and retest the component on the launch vehicle. Launch of the GPS III SV02 mission is now targeted for no earlier than Thursday, Aug. 22, 2019.

Five Things to Know About NASA’s Deep Space Atomic Clock

PASADENA, Calif. (NASA/JPL-Caltech PR) — NASA is sending a new technology to space in late June that will change the way we navigate our spacecraft — even how we send astronauts to Mars and beyond. Built by NASA’s Jet Propulsion Laboratory in Pasadena, California, the Deep Space Atomic Clock is a technology demonstration that will help spacecraft navigate autonomously through deep space. No larger than a toaster oven, the instrument will be tested in Earth orbit for one year, with the goal of being ready for future missions to other worlds.
