Live coverage: Japanese cargo craft arrives at space station

Leveraging progress made to build a human-rated space plane for NASA’s commercial crew program, Sierra Nevada Corp. said this week it has offered a cargo-carrying version of the Dream Chaser spacecraft to resupply the International Space Station beginning in 2018.

Nearly a decade in the making, NASA and SpaceX have set May 27 as the target launch date for the first crewed space mission to launch into orbit from U.S. soil since the retirement of the space shuttle in 2011.

Fifty years to the day after Neil Armstrong stepped onto the surface of the moon, a NASA astronaut, an Italian flight engineer and a Russian commander blasted off from Kazakhstan Saturday aboard a Soyuz spacecraft, chased down the International Space Station and glided in for a picture-perfect docking.
