Engine failure delays mission

Orbital Sciences Corp. is delaying the launch of its second robotic resupply mission to the International Space Station to investigate the failure of a rocket engine during a test at NASA's Stennis Space Center, Miss. An Aerojet Rocketdyne AJ26, one of two used on Orbital's Antares launch vehicle, failed midway through a test. Orbital Sciences will postpone the June 10 launch of the company's unmanned Cygnus spacecraft. The mission will not launch to the space station before June 17. (Source: space.com, 05/28/14) Previous
