Live coverage: SpaceX launches its fifth Falcon 9 flight of the year

The mission featured the launch of NASA’s largest spacecraft bound on a planetary mission. Liftoff from Launch Complex 39A happened 12:06 p.m. EDT (1606 UTC).

SpaceX launched a prototype Starship rocket Tuesday from its Boca Chica, Texas, flight facility, successfully sending the silver booster up to an altitude of about six miles as planned. But the unpiloted test flight ended with a spectacular explosion when the rocket failed to right itself and slow down enough for a tail-first landing.

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.
