During tonight’s Falcon 9 launch of Starlink, the second stage engine did not complete its second burn. As a result, the Starlink satellites were deployed into a lower than intended orbit.
SpaceX has made contact with 5 of the satellites so far and is attempting to have them raise orbit using their ion thrusters.
Today's Soyuz launch was aborted at the 20-second mark. The spacecraft and crew remain safe. Teams at Baikonur will provide updates as they make assessments.
