Photos: Atlas 5 rocket aims for International Space Station

An Orbital ATK Cygnus supply ship packed with 3.7 tons of cargo, supplies and experiments rode an Antares rocket into orbit from Virginia’s Eastern Shore on Sunday, setting course on a two-day pursuit of the International Space Station.

Rocket Lab’s next launch from New Zealand, set for Friday, will carry a data recorder to measure the aerothermal environments encountered by the Electron launcher’s first stage during descent back into the atmosphere, information engineers say is crucial to successfully achieving the company’s newly-announced plan to recover and reuse the booster.

Streaking away from Cape Canaveral less than an hour before sunrise Wednesday, an Atlas 5 launcher painted a memorable spectacle in the skies over Florida, catching the first rays of the morning as it rocketed out of the stratosphere with a U.S. Navy communications satellite.
