Time-lapse video: The Falcon Heavy goes vertical again

SpaceX engineers have narrowed the cause of last week’s unsuccessful landing of a Falcon 9 rocket booster on a barge in the Atlantic Ocean on a commanding issue with an engine throttle valve, according to Elon Musk, the company’s founder and chief executive.

The Starlink 10-28 mission delivered 28 broadband internet satellites into low Earth orbit. Liftoff of the Falcon 9 rocket from pad 40 at Cape Canaveral Space Force Station at 4:21 a.m. EDT (0821 UTC).

A refurbished SpaceX Crew Dragon spaceship linked up with the International Space Station early Saturday more than 260 miles above Earth, delivering four veteran astronauts to the orbiting research complex and temporarily raising the lab’s crew complement to 11.
