ULA launches 10th WGS comms satellite for U.S. military

Science
March 15 (UPI) -- United Launch Alliance launched a communications satellite for the United States Air Force on Friday evening at 8:26 p.m. EST. ULA's Delta IV rocket had a successful launch and jettisoned its liquid rocket motors on time as it entered the atmosphere. Just a few minutes after liftoff, the first and second stages separated. The rocket's second stage executed a series of engine burns to properly position the payload. After a technical glitch delayed proceedings, ULA released a new liftoff target of 7:52 p.m. Just minutes later, ULA announced a problem with NASA's Tracking and Data Relay Satellite System "will delay liftoff beyond our new ... launch time." The sun is rising over the #DeltaIV with #WGS10 on the launch pad this morning. Liftoff planned for today, March 15 at ...
