Watch the Falcon 9 launch from pad 39A

Russia is delaying the return to Earth of three space station crew members by about a month in the wake of the failure of a Russian Progress supply ship that spun out of control moments after reaching orbit April 28. Launch of three fresh crew members also will be delayed, from May 26 to late July.

Russian ground crews are readying a robotic Progress cargo freighter for launch Thursday on an expedited trek to the International Space Station that should take less than three-and-a-half hours from liftoff to docking, cutting in half the normal transit time.

Russian engineers have a “really, really good idea” about what went wrong during a Soyuz launch to the International Space Station Oct. 11, forcing the ship’s two-man crew to carry out an emergency abort, NASA Administrator Jim Bridenstine said Tuesday. He added that he expects the Russians to resume piloted Soyuz flights in December.
