Photos: Atlas 5 rocket aims for International Space Station

In a mission marking the end of an era, NASA astronaut and former virus hunter Kate Rubins, using NASA’s last currently contracted seat on a Russian Soyuz spacecraft, blasts off Wednesday with two cosmonaut crewmates on a flight to the International Space Station.

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.

Two U.S. military satellite launches planned for this fall from Cape Canaveral are being delayed to 2018 due to separate factors, the Air Force says.
