For the fourth time this month, SpaceX has launched a Falcon 9 rocket from Florida’s Space Coast with another 60 Starlink internet satellites. Liftoff of the Falcon 9 from pad 40 at Cape Canaveral Space Force Station occurred at 4:28 a.m. EDT (0828 GMT) Wednesday. The Falcon 9’s booster landed on an offshore drone ship.
Russian commander Sergey Ryzhikov, flight engineer Sergey Kud-Sverchkov, and NASA astronaut Kate Rubins climbed into their Soyuz landing craft and undocked from the International Space Station at 9:34 p.m. EDT Friday (0134 GMT Saturday). The trio touched down on the barren steppes of Kazakhstan at 12:56 a.m. EDT (0456 GMT) to wrap up six months in orbit.
The satellite awaiting launch early Saturday from California aboard the final flight of the venerable Delta 2 rocket should allow scientists to more precisely track changes in our planet’s ice sheets, using six green laser beams to chart the height and slope of polar ice and glaciers, providing a key input into climate change research.
