United Launch Alliance ground crews are putting the final touches on a Delta 4 rocket scheduled for blastoff Friday evening from Cape Canaveral with a U.S. Air Force communications satellite.

Five days after launching from Japan, an HTV supply ship arrived Monday at the International Space Station. Capture of the HTV with the station’s robotic arm occurred at 8:13 a.m. EDT (1213 GMT). It’s the last cargo mission to the space station before the arrival of two NASA astronauts on the first crewed U.S. flight to the orbiting research facility since 2011.

Boeing said Tuesday it is “making excellent progress” toward launching a second unpiloted test flight of its Starliner crew capsule to the International Space Station by the end of this year or in early January, setting the stage for the first Starliner demonstration mission with astronauts in mid-2021.
