SpaceX launches Starlink satellites after string of scrubs

Posted on

ORLANDO, Fla., Oct. 6 (UPI) — After repeated delays due to weather and other problems, SpaceX on Tuesday successfully launched a shipment of 60 Starlink communications satellites from Florida.

SpaceX’s Falcon 9 rocket lifted off about 7:30 a.m. EDT from Launch Complex 39A at the Kennedy Space Center. Multiple previous launches had been postponed since Sept. 17.

The flight’s reusable booster landed on a drone ship in the Atlantic Ocean following the launch.

SpaceX founder Elon Musk had tweeted that he would travel to Florida to review the launch following a scrub Friday night he said was due to an “unexpected pressure rise” in a gas generator. The launch was postponed again Monday morning due to rainstorms in the area.

“We will need to make a lot of improvements to have a chance of completing 48 launches next year!” Musk tweeted. “We’re doing a broad review of launch site, propulsion, structures, avionics, range & regulatory constraints this weekend.”

The delays were mirrored by a string of similar scrubs in recent weeks for its main rival, United Launch Alliance, which is trying to send a spy satellite into orbit for the Defense Department.

ULA also has cited weather and mechanical issues with ground systems for the delays that have kept its powerful Delta IV Heavy rocket, carrying the spy satellite, on the launch pad.

“There’s a thousand ways that a launch can go wrong, and only one way it can go right,” Siva Baradvaj, SpaceX space operations engineer, said during a live broadcast for a launch attempt last week.

That attempt was scrubbed due to a sensor reading on ground systems, but Baradvaj noted that the rocket and spacecraft were in good shape.

Tuesday’s launch will ultimately grow the number of Starlink satellites in orbit to well over 700. More have

SpaceX scrubs Starlink satellite launch Thursday due to ground sensor reading

A Falcon 9 blasts off on Aug. 30.

The Falcon 9 rocket booster that sent NASA astronauts to the International Space Station in May is set to get recycled again when SpaceX sends 60 more Starlink satellites to orbit atop its column of fire, but it didn’t happen Thursday as planned. 

The launch, originally scheduled for September, has been postponed multiple times due to weather, including on Monday morning when heavy clouds above Florida’s Cape Canaveral prevented launch at the last second. On Thursday, another launch was scrubbed 18 seconds before blastoff due to an aberrant ground sensor reading. A new target launch date has not yet been announced. 

“All in a day’s work for the launch team. They’ll investigate, diagnose probable cause, fix the problem, and get us ready for the next launch attempt,” SpaceX spacecraft operator Siva Bharadvaj tweeted

Elon Musk’s trademark reusable rocket will be making its third flight when it lifts off from Kennedy Space Center. This specific unit sent astronauts Doug Hurley and Bob Behnken to orbit in May and then launched a South Korean satellite in July. So far, SpaceX has managed to launch and land the same rocket up to six times

When the launch finally gets off the ground, it should be fairly routine. It will be the 13th Starlink mission so far, and SpaceX is planning on dozens more as it grows its broadband mega-constellation.
