Watch the Falcon 9 light its engines for a static test fire (members only)

The Russian Soyuz rocket that will carry a three-person crew to the International Space Station Wednesday has arrived on its launch pad at the Baikonur Cosmodrome in Kazakhstan.

Investigators probing the Sept. 1 explosion of a SpaceX Falcon 9 rocket on its launch pad in Florida believe a high-pressure gas tank inside the launcher’s upper stage most likely burst due to the conditions of the helium loaded into it, a finding that could simplify fixes needed before the commercial booster can return to service.

South Korea’s space agency has signed a contract to launch an Earth observation satellite into orbit in 2020 aboard Russia’s Angara rocket, giving the new booster its first commercial customer, International Launch Services announced Monday.
