Live coverage: HTV cargo freighter arrives at space station

An Indian rocket lifted off with two British-built Earth-imaging satellites at 1638 GMT (12:38 p.m. EDT) Sunday — one developed with the financial backing of the UK government to demonstrate radar reconnaissance technology, and another destined for use by a commercial imaging company in Asia.

More photos show the successful liftoff of the United Launch Alliance Atlas 5 rocket flight carrying the Cygnus commercial cargo spacecraft for Orbital ATK and the International Space Station.

The satellite awaiting launch early Saturday from California aboard the final flight of the venerable Delta 2 rocket should allow scientists to more precisely track changes in our planet’s ice sheets, using six green laser beams to chart the height and slope of polar ice and glaciers, providing a key input into climate change research.
