Video: Atlas 5 rocket launches space station cargo mission

This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into orbit from Cape Canaveral with the SBIRS GEO Flight 3 satellite for U.S. military infrared reconnaissance. Launch is scheduled for Thursday at 7:46 p.m. EST (0046 GMT).

Two astronauts floated outside the International Space Station early Friday for the first of four planned spacewalks to wrap up a complex multi-year job to replace 48 aging batteries in the lab’s solar power system with 24 more powerful lithium-ion units.

The commercial SpaceX Dragon cargo-delivery craft with the experimental BEAM module — the Bigelow Expandable Activity Module — arrives at the International Space Station two days after launching from Cape Canaveral.
