Video: Fourth X-37B launch highlights

A Russian Progress supply ship launched Tuesday from the Baikonur Cosmodrome in Kazakhstan, firing into orbit from a snow-covered pad to haul three tons of fuel, water and equipment to the International Space Station.

A Chinese rocket measuring around 100 feet long that launched earlier this month will likely plunge back into Earth’s atmosphere some time Monday, becoming the most massive object in decades to fall out of orbit in an uncontrolled manner.

The 330-foot-tall mobile service tower is rolled away from the United Launch Alliance Delta 4 rocket at Cape Canaveral’s pad 37B in the hours before the scheduled liftoff. The 9-million-pound gantry was retracted the length of a football field in preparation for launch of the Air Force’s WGS 9 communications satellite into Earth orbit.
