Photos: Atlas 5 rocket aims for International Space Station

The power and propulsion section of Orbital ATK’s next Cygnus supply ship, featuring new solar panel and fuel tank designs, arrived at NASA’s Kennedy Space Center in Florida on Wednesday to be joined with a cargo module for a Dec. 3 launch to the International Space Station.

A European Ariane 5 rocket fired into a gloomy sky Thursday over French Guiana and streaked into space from the tropical launch base with 2.9 million pounds of thrust from two solid rocket boosters and a hydrogen-fueled Vulcain 2 main engine.

A ULA Atlas 5 rocket is set to launch no earlier than 2 p.m. EDT (1800 UTC) on Friday, Oct. 6. It will sent up two prototype satellites for Amazon’s Project Kuiper satellite internet constellation.
