After waiting more than a week for good weather, SpaceX launched a Falcon 9 rocket Wednesday from Cape Canaveral with 60 more satellites for the company’s Starlink Internet network, continuing to build out a fleet of fleet of orbiting broadband relay stations that could eventually number in the thousands.
The 229-foot-tall (70-meter) Falcon 9 rocket fired up at 9:06:49 a.m. EST (1406:49 GMT) Wednesday and climbed away from from Cape Canaveral’s Complex 40 launch pad. An incandescent flame from the rocket’s nine Merlin 1D main engines — collectively generating 1.7 million pounds of thrust — trailed more than 20 stories behind the launcher.
A roar from the Falcon 9’s engines reached spectators a few seconds later as the rocket arced toward the northeast into clear skies over Florida’s Space Coast.
The liftoff Wednesday came after a series of weather delays since last week. After performing a standard pre-launch test-firing of the rocket, SpaceX pushed back the launch from Jan. 21 to Jan. 24, then to Monday, Jan. 27, to wait for improved weather conditions in the Atlantic Ocean, where SpaceX stationed ships to retrieve the first stage and payload fairing from the Falcon 9 rocket.
SpaceX scrubbed a launch attempt Monday due to strong upper level winds, then bypassed a launch opportunity Tuesday, again wait for better weather in the downrange recovery area.
Weather conditions at Cape Canaveral appeared ideal for a launch Wednesday, and SpaceX’s 80th Falcon 9 flight put on a spectacular show.
Two-and-a-half minutes after liftoff, the rocket’s first stage shut down its engines and dropped away from the Falcon 9’s second stage. Seconds later, the upper stage’s single Merlin engine — modified with an enlarged nozzle for better performance in space — ignited to accelerate the 60 Starlink satellites into orbit.
The Falcon 9 jettisoned its clamshell-like payload fairing nearly three-and-a-half minutes into the mission.
Flying tail first, the rocket’s first stage booster reignited three of its nine engines to guide it toward SpaceX’s drone ship “Of Course I Still Love You” positioned around 400 miles (630 kilometers) northeast of Cape Canaveral. A final landing burn using the center engine slowed the booster for a controlled vertical touchdown on the football field-sized barge, marking the 49th time SpaceX has recovered one of its rockets intact.
The booster flown Wednesday was making its third trip to space, following successful launches and landings in March 2019 and June 2019 on flights carrying SpaceX’s Crew Dragon spacecraft and Canada’s Radarsat Constellation Mission. With Wednesday’s mission, the booster has launched from all three of SpaceX’s active launch pads in Florida and California.
The two halves of the Falcon 9’s payload shroud used cold gas thrusters to maneuver into the proper orientation for descent, then unfurled parafoils for a gentle fall toward the Atlantic Ocean. SpaceX’s two fast-moving fairing recovery boats — named “Ms. Tree and “Ms. Chief” — tried to catch both halves of the Falcon 9’s aerodynamic fairing.
SpaceX confirmed Ms. Tree caught one side of the shroud in a giant net. Ms. Chief, equipped with a similar net, failed to snag the other half of the fairing before it fell into the sea, but teams were expected to pull the hardware from the ocean for inspections and refurbishment.
