Live coverage: SpaceX supply ship returns to Earth

Astronaut Christina Koch, launched to the International Space Station in March, marks her 289th day in space Saturday, breaking retired astronaut Peggy Whitson’s world record for the longest single spaceflight by a female.

SpaceX’s first upgraded Falcon 9 “Block 5” rocket was raised vertical at launch pad 39A early Thursday in preparation for liftoff from the Kennedy Space Center, debuting enhancements aimed at making the booster more reusable and more reliable.

A SpaceX Falcon 9 rocket lifted off from Cape Canaveral at 1:50 a.m. EDT (0550 GMT) Sunday with the Telstar 19 VANTAGE communications satellite, a powerhouse spacecraft designed to beam broadband and in-flight WiFi signals across the Americas and the North Atlantic. The rocket’s first stage successfully landed at sea aboard SpaceX’s drone ship.
