Live coverage: Soyuz MS-14 docks at space station

NASA has selected a SpaceX Falcon 9 rocket — flying with a reused first stage booster — to launch the Imaging X-ray Polarimetry Explorer mission from pad 39A at the Kennedy Space Center in Florida in April 2021, bypassing Northrop Grumman’s air-launched Pegasus rocket for the task.

SpaceX has delayed liftoff of its next cargo ship bound for the International Space Station until Friday, setting up a one-shot attempt to launch the commercial supply carrier from Cape Canaveral before a potential slip to late December due to high solar angles in orbit.

Russian technicians rolled a Soyuz rocket from its integration hangar to the launch pad in French Guiana on Tuesday morning, positioning the booster to receive two Galileo navigation satellites ahead of liftoff Friday.
