SpaceX is ready to make its fifth attempt to launch a Falcon nine rocket carrying the U.S. Air Force’s 1st GPS III.
The latest attempt is slated to happen at 8:51 a.m. Sunday from Cape Canaveral Air Force Station.
SpaceX has made four previous attempts this past week however had to scrub all of them.
The launch was initially set to happen on Dec. 18, but the SpaceX team scrubbed it because of an “out of family reading on first-stage sensors.” The backup launch attempt on Dec. nineteen was also scrubbed so the team may further evaluate the reading.
Weather was to blame for the third launch attempt being scrubbed on Dec. 20. The team also stood down from an attempt on Saturday because of strong upper-level winds.
Once the launch happens, SpaceX says the GPS satellite will be deployed to medium Earth orbit about an hour and fifty six minutes after the rocket lifts off.
The GPS system will deliver positioning, navigation and timing services supporting vital United State. and allied operations worldwide, according to a news release from SpaceX.
The Associated Press reports the satellites will have a stronger military signal that’s harder to jam and will give a new civilian signal compatible with other countries navigation satellites.
