Live broadcast of the countdown and launch of the SpaceX Falcon 9 rocket from site 40 at the Cape Canaveral Space Forces station in Florida. The mission is to launch the next batch of SpaceX with 46 Starlink broadband satellites. Text updates will automatically appear below. Follow us Twitter.
Forty-six more Starlink Internet satellites are ready to launch on Monday from Cape Canaveral, where SpaceX teams are counting down to take off the Falcon 9 rocket at 9:44 a.m. EST (14:44 GMT).
You can watch our live broadcast of the launch on this page starting at 8:30 a.m. EST (1:30 p.m. GMT).
The 229-foot (70-meter) Falcon 9 rocket, powered by nine first-degree Merlin engines, will head southeast over the Atlantic to bring 46 Starlink Internet satellites into orbit with an inclination of 53.2 degrees to the equator.
The mission continues to rapidly build the Starlink network, and this launch is poised to increase the total number of Starlink satellites launched to more than 2,100. More than 1,500 satellites are currently operating, transmitting high-speed, low-latency Internet signals worldwide.
SpaceX’s Falcon 9 rocket rolled from its hangar to Site 40 at the Space Forces station at Cape Canaveral last weekend in preparation for the company’s seventh mission this year. This battle is known as Starlink 4-8 in the SpaceX launch schedule.
In a recent report, SpaceX said it has more than 145,000 subscribers in 25 countries for Starlink’s private Internet service.
SpaceX continues to deploy about 4,400 Starlink satellites in five orbital “shells” at several different altitudes and at different inclinations or angles to the equator. The launch on Monday is aimed at an orbital projectile with an inclination of 53.2 degrees and an altitude of 335 miles (540 kilometers).
The Falcon 9 rocket twice launched Merlin’s single top-of-the-range engine to reach an almost circular orbit of 202 miles to 209 miles (325 by 337 kilometers) in altitude. Deployment of 46 satellites is scheduled approximately 63 minutes after takeoff, then the ship will use ion engines to ascend to an altitude of 335 miles.
Monday’s mission is moving fewer Starlink satellites into higher, more circular orbits than Starlink’s recent SpaceX missions. The change was apparently ordered after SpaceX lost 38 Starlink satellites days after launching into lower altitude orbit on February 3rd.
The solar storm caused higher-than-expected levels of atmospheric resistance, causing Starlink satellites to re-enter the atmosphere and burn up before they were able to turn on ion engines and maneuver into their operating orbit.
The first stage of the mission booster on Monday, flight number B1058, flies into its 11th mission. The booster debuted on May 30, 2020 during the launch of the first SpaceX crew mission.
The unmanned spacecraft SpaceX “A Shortfall of Gravitas” is at a station in the Atlantic Ocean near the Bahamas to land a launch vehicle of the first degree.
