After the rocket’s nine Merlin engines pass an automated health check, hold-down clamps will release the Falcon 9 booster for liftoff from Complex 40.


SpaceX’s Falcon 9 rocket is ready for liftoff from Cape Canaveral on Tuesday carrying the U.S. Air Pressure’s subsequent GPS 3-series navigation satellite tv for pc destined for an orbit greater than 12,000 miles above Earth.

The 229-foot-tall (70-meter) rocket is poised for launch from pad 40 at Cape Canaveral Air Pressure Station in Florida at 3:55:48 p.m. EDT (1955:48 GMT) Tuesday on the opening of a 15-minute launch window.

The Lockheed Martin-built GPS Three SV03 satellite tv for pc mounted atop the rocket is the third member of an upgraded technology of GPS navigation spacecraft, that includes higher-power indicators which might be extra resilient to jamming, and extra broadcast frequencies to make the GPS community extra interoperable with different navigation satellite tv for pc fleets.

In contrast to SpaceX’s earlier launch of a GPS payload in 2018, the mission will fly a barely completely different profile to order gas for touchdown of the Falcon 9 booster. Learn our mission preview story for extra data.

The timeline beneath outlines the launch sequence for the Falcon 9 flight with the GPS Three SV03 spacecraft.

See our Mission Standing Middle for particulars on the launch.

T+1:29:14: GPS Three SV03 Separation

The SES 9 satellite separates from the Falcon 9 rocket in an orbit with a predicted high point of about 39,300 kilometers (24,400 miles), a low point of 290 kilometers (180 miles) and an inclination of 28 degrees. Due to the decision to burn the second stage nearly to depletion, there is some slight uncertainty on the orbital parameters based on the exact performance of the launcher.The SES 9 satellite separates from the Falcon 9 rocket in an orbit with a predicted high point of about 39,300 kilometers (24,400 miles), a low point of 290 kilometers (180 miles) and an inclination of 28 degrees.
