Live coverage of the SpaceX Falcon 9 rocket countdown and launch from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The Starlink 4-19 mission launched another batch of 53 SpaceX Starlink broadband satellites. follow us twitter.
SpaceX launched the Falcon 9 reusable amplifier from Kennedy Space Center in Florida for the 13th time on Friday, putting 53 Starlink internet satellites into orbit. Panel 39A started at 12:09 EDT (1609 GMT).
Falcon 9 will head northeast of Kennedy to deliver packets from the broadband relay station in an orbit between 144 miles and 209 miles (232 x 337 km) in altitude. The 53 flat satellites are expected to be deployed from Falcon 9’s upper stage approximately 15 minutes after liftoff.
The launch will kick off a busy weekend for SpaceX, with two more Falcon 9 flights on Saturday and Sunday from Vandenberg, Calif., and then from the Cape Canaveral space station, a few miles south of the St. Kennedy.
On Friday’s mission, SpaceX will launch 2,706 Starlink internet satellites, including prototypes and test units that are no longer in use, nearly an area larger than any other fleet of spacecraft. Friday’s debut will mark SpaceX’s 48th mission primarily dedicated to putting the Starlink Internet satellites into orbit.
The SpaceX launch team will be stationed in the firing room at the Kennedy launch control center and will begin loading engines of ultra-cold condensed oil and liquid oxygen onto the 229-foot (70-meter) Falcon 9 spacecraft at 35 minutes T-minus on Friday. .
Helium pressure will also flow into the rocket during the last half hour of the countdown. In the last seven minutes before takeoff, the Falcon 9 Merlin’s main engines will be thermally conditioned for flight in a procedure known as “chilldown”. Falcon 9’s guidance and security systems will also be configured to take off at 12:08:50
After liftoff, the 229-foot (70 m) Falcon 9 rocket will direct 1.7 million pounds of thrust – produced by nine Merlin engines – to control in the Northeast Atlantic.
The missile will exceed the speed of sound by about a minute and then shut off all nine main engines two and a half minutes after takeoff. The afterburner will fire from the Falcon 9’s upper stage, then fire from the cold gas steering engines and retractable titanium grille fins to help guide the vehicle back into the atmosphere.
Inhibitory firing will delay the projectile’s landing aboard the drone ship “A Shortfall of Gravitas” by approximately 400 miles (650 kilometers) after approximately eight and a half minutes of takeoff.
Friday’s volatile afterburner stage – number B1060 – will set a new record for becoming the most flying member of SpaceX’s reusable rocket fleet. It was first launched on June 30, 2020 with the launch of a US Army GPS Navigation Satellite and flew again in September and October 2020 on Starlink missions.
It was launched six times in 2021 using the Türksat 5A geostationary communications satellite, four Starlink missions and the small SpaceX Transporter 2 satellite mission. The debut on Friday will be the fourth flight in 2022, all flights are dedicated to the Starlink network.
SpaceX has qualified Falcon 9 afterburners for at least 15 missions, down from the previous lifespan of ten flights for each Falcon 9 first stage.
The first landing on Friday’s mission will take place just before the Falcon 9’s stage two engine shuts down to put the Starlink satellites into orbit. Spacecraft 53, built by SpaceX in Redmond, Washington, is scheduled to deploy at T+ plus 15 minutes and 26 seconds.
Retention rails will launch from the Starlink payload, allowing packaged satellites to fly freely from Falcon 9’s upper stage into orbit. 53, the spacecraft will rotate and power the solar panels through automatic activation steps and then use krypton-powered ion engines to maneuver into its operational orbit.
The Falcon 9 guidance computer is designed to place satellites in an elliptical orbit between 144 and 209 miles high, with an orbit inclination of 53.2 degrees to the equator. The satellites will use the onboard thrust to do the rest of the work to achieve a circular orbit of 540 kilometers above Earth.
Friday’s launch will be the first to put Starlink satellites into a low-altitude elliptical transfer orbit since February, when aerodynamic drag from the solar storm caused nearly 40 Starlink satellites to re-enter the atmosphere shortly after launch. Since then, all SpaceX Starlink launches have included two upper-stage engine torches to ascend to a higher orbit for spacecraft placement.
Starlink satellites will fly Friday’s mission in one of five orbital “shells” used in the SpaceX global network. Once in operational orbit, the satellites will enter commercial service and begin transmitting broadband signals to consumers who will be able to purchase the Starlink service and connect to the network via a SpaceX-provided ground station.
