Photos: Atlas 5 rocket aims for International Space Station

Watch as Russian cosmonaut Alexey Ovchinin and NASA astronaut Nick Hague launch aboard a Soyuz rocket bound for the International Space Station but a Soyuz booster failure cut short their ascent into orbit.

The launch from Cape Canaveral of a top secret spy satellite for the U.S. government was aborted at the last moment early Saturday as its United Launch Alliance Delta 4-Heavy rocket ignited three main engines, a dramatic cutoff of the countdown that will delay the mission by at least one week.

NASA has announced the nine finalists for the name of the space agency’s next Mars rover — scheduled for launch in July — and invited the public to vote on the candidates before making a final selection in the coming months.
