Video: Change of command aboard International Space Station

A NASA instrument built to help astronomers learn about the structure and behavior of neutron stars, super-dense stellar skeletons left behind by massive explosions, has been mounted to an observation post outside the International Space Station after delivery aboard a SpaceX supply ship earlier this month.

The vehicle launched on a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station on Saturday, April 11, at 7:41 a.m. EDT (1141 UTC). Capture by the space station’s Canadarm2 is happened on Monday, April 13, at 12:19 pm CT (1:19 pm ET / 1719 UTC).

Russian ground controllers decided Tuesday to delay the docking of a Progress supply freighter to the International Space Station until Thursday after telemetry signals indicated two radar navigation antennas may not have deployed following the ship’s launch from Kazakhstan.
