SpaceX aborts launch of GPS Space Force satellite with 2 seconds to go

Posted on

SpaceX aborted a scheduled launch of a US military GPS satellite on Friday night with just about two seconds left in the countdown. The launch was scheduled for a 15-minute window that opened at 6:43 p.m. PT. All appeared to be proceeding smoothly, until two seconds before launch. SpaceX was just starting the engine ignition sequence when it stopped the clock.

“Standing down from tonight’s launch attempt of GPS III-4,” SpaceX tweeted a few minutes before 7 p.m. PT, though it didn’t say whether a ground or flight vehicle issue was to blame. The next launch window opens at 6:39 p.m. PT Saturday, SpaceX said. 

SpaceX and the US Space Force are getting along famously. Friday’s attempted launch in Florida follows a Space Force Falcon 9 launch in June

Once Elon Musk’s company does launch the GPS satellite, it’ll attempt to land the Falcon 9’s first stage on a drone ship in the Atlantic Ocean. The spacecraft is scheduled to deploy about 90 minutes after liftoff.

SpaceX hosted a livestream of Friday’s launch, which you can watch below to see how events unfolded.

The GPS III Space Vehicle (SV) 04 is the fourth in a series of GPS satellites operated by the US Space Force, the newest branch of the military. It’ll join a larger satellite constellation already in orbit.

SpaceX aborted a scheduled launch of a US military GPS satellite from Florida on Friday night with just about two seconds left in the countdown. The launch was scheduled for a 15-minute window that opened at 6:43 p.m. PT, with the weather forecast at 70% favorable for liftoff. All appeared to be proceeding smoothly, until two seconds before launch. SpaceX was just starting the engine ignition sequence when it stopped the clock.

Watch live tonight! SpaceX to launch advanced GPS III SV04 navigation satellite

Posted on

SpaceX is now targeting a Friday, Oct. 2, to launch for its next GPS navigation satellite mission for the U.S. military. Liftoff is set for 9:43 p.m. EDT (0143 Oct. 3 GMT)

A SpaceX Falcon 9 rocket will launch the GPS III SV04 satellite for the U.S. Space Force and Air Force  from Space Launch Complex 40 at the Cape Canaveral Air Force Station in Florida.

SpaceX is targeting Friday, October 2, for a Falcon 9 launch of the GPS III Space Vehicle 04 mission from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station in Florida. The 15-minute launch window opens at 9:43 p.m. EDT, or 01:43 UTC on October 3.

Following stage separation, SpaceX will land Falcon 9’s first stage on the “Just Read the Instructions” droneship, which will be stationed in the Atlantic Ocean. The spacecraft will deploy approximately 1 hour and 29 minutes after liftoff.

Last week, the United States Space Force’s Space and Missile Systems Center (SMC) announced an agreement with SpaceX to launch previously flown boosters on future National Security Space Launch (NSSL) missions.

You can watch the launch webcast here, starting about 15 minutes before liftoff.

Tonight:  Cygnus NG-14 cargo ship for NASA

On Friday, Oct. 2, a Northrop Grumman Cygnus cargo ship carrying nearly 4 tons of NASA cargo will launch toward the International Space Station from the agency’s Wallops Flight Facility on Wallops Island, Virginia. 

A Northrop Grumman-built Antares rocket will launch the Cygnus spacecraft on the CRS-14 (or NG-14) mission from Pad OA at Wallops at 9:16 p.m. EDT (0116 GMT). The mission has been delayed from Sept. 29 due to bad weather. NASA’s webcast will begin at 9 p.m. EDT (0100 GMT).
