Live coverage: Falcon 9 disintegrates after launch

SpaceX continued its blistering pace of orbital launches with its ninth and final Starlink launch of August. Liftoff of its Falcon 9 rocket from pad 40 at Cape Canaveral Space Force Station happened at 7:49 a.m. EDT (1149 UTC).

A NASA official said Friday that SpaceX’s Crew Dragon spacecraft could be ready to ferry astronauts Doug Hurley and Bob Behnken to the International Space Station as soon as early March, pending the results from a major demonstration of the ship’s launch abort system this weekend, a pair of parachute drop tests, and space station crew schedules.

The last flight of the single-core variant of United Launch Alliance’s Delta 4 rocket lifted off at 9:06 a.m. EDT (1306 GMT) Thursday from Cape Canaveral Air Force Station, Florida. The 207-foot-tall launcher carried a GPS navigation satellite into orbit for the U.S. Air Force.
