Video: Fourth X-37B launch highlights

A SpaceX Dragon cargo ship arrived at the International Space Station Sunday with more than 5,700 pounds of supplies and experiments. The supply ship was captured by the station’s Canadian-built robotic arm at 5:05 a.m. EST (1005 GMT).

Some of America’s most critical surveillance satellites, final members of other spacecraft series and a probe that will touch an asteroid are among 15 rocket flights planned by United Launch Alliance in 2016.

SpaceX’s fifth launch of replacement spacecraft for Iridium’s global voice and data communications network is set for March 29 from Vandenberg Air Force Base in California, a flight that Iridium hopes will signal the start of a brisk pace of West Coast missions to complete deployment of the telecom company’s initial 75-satellite constellation this summer.
