SpaceX set to launch 53 extra Starlink web satellites – Spaceflight Now

SpaceX plans to launch a reusable Falcon 9 booster on Friday for a file thirteenth time from Kennedy House Heart in Florida, carrying 53 extra Starlink web satellites into orbit. Liftoff from Pad 39A is scheduled for 12:08 p.m. EDT (4:08 p.m. GMT).

The Falcon 9 will head northeast of Kennedy to ship the Broadband Relay Stations flat to an orbit between 144 miles and 209 miles in altitude (232 by 337 kilometers). The deployment of the 53 flat satellites from the higher stage of Falcon 9 is deliberate roughly quarter-hour after liftoff.

The launch will kick off a busy weekend for SpaceX, with two extra Falcon 9 flights scheduled for Saturday and Sunday from Vandenberg House Pressure Base in California after which from Cape City House Pressure Station. Canaveral, a couple of miles south of Kennedy House Heart.

With Friday’s mission, SpaceX may have launched 2,706 Starlink web satellites, together with prototypes and take a look at items which might be now not in service, almost an order of magnitude extra spacecraft than another fleet on the planet. spacecraft. Friday’s launch will mark the forty eighth SpaceX mission primarily devoted to carrying Starlink web satellites into orbit.

Stationed inside a firing vary on the Kennedy Launch Management Heart, the SpaceX launch workforce will start loading super-chilled and densified kerosene and liquid oxygen boosters into the 229-meter Falcon 9 automobile. toes excessive (70 meters) at T-minus 35 minutes Friday.

The pressurizing helium can even circulate into the rocket within the final half hour of the countdown. Over the last seven minutes earlier than liftoff, Falcon 9’s Merlin primary engines will probably be thermally conditioned for flight via a process often called “cooling down”. Falcon 9’s vary steerage and security methods can even be configured for launch at 12:08:50 p.m.

After liftoff, the 229-foot-tall (70-meter) Falcon 9 rocket will direct its 1.7 million pound thrust – produced by 9 Merlin engines – to move northeast over the Atlantic Ocean .

The rocket will exceed the velocity of sound in a few minute, then shut down its 9 primary engines two and a half minutes after liftoff. The thruster will exit from Falcon 9’s higher stage, then fireplace pulses from chilly fuel management thrusters and lengthen titanium grid fins to assist carry the automobile again into the environment.

Two brake burns will gradual the rocket to land on the drone ship “A Shortfall of Gravitas” roughly 400 miles (650 kilometers) roughly eight and a half minutes after liftoff.

Friday’s flying booster stage – tail quantity B1060 – will set a brand new file for turning into probably the most flown member of SpaceX’s reusable rocket fleet. It debuted on June 30, 2020, with the launch of a GPS navigation satellite tv for pc for the US army, then flew once more in September and October 2020 on Starlink missions.

It was launched six instances in 2021 with the geostationary communications satellite tv for pc Türksat 5A, 4 Starlink missions and the rideshare mission of SpaceX’s small satellite tv for pc Transporter 2. Friday’s launch would be the booster’s fourth flight of 2022, all flights devoted to the Starlink community.

SpaceX has certified Falcon 9 boosters for at the very least 15 missions, up from the earlier design lifetime of 10 flights for every Falcon 9 first stage.

Friday’s mission first-stage touchdown will happen moments earlier than the Falcon 9’s second-stage engine shuts all the way down to launch the Starlink satellites into orbit. The separation of the 53 spacecraft, constructed by SpaceX in Redmond, Washington, is scheduled for T+plus quarter-hour, 26 seconds.

Retention rods will launch from the Starlink payload stack, permitting flat-packed satellites to fly freely from the Falcon 9 higher stage into orbit. The 53 spacecraft will deploy photo voltaic arrays and undergo automated activation levels, then use krypton-powered ion engines to maneuver into their operational orbit.

The Falcon 9 steerage laptop aimed to deploy the satellites into an elliptical orbit between 144 and 209 miles in altitude, at an orbital inclination of 53.2 levels from the equator. The satellites will use onboard propulsion to do the remainder of the work to succeed in a round orbit 335 miles (540 kilometers) above Earth.

Friday’s launch would be the first to put Starlink satellites in a low-altitude elliptical switch orbit since February, when aerodynamic drag produced by a photo voltaic storm swept almost 40 Starlink satellites into the environment shortly after the launch. launch. Since then, all of SpaceX’s Starlink launches have included two upper-stage engine burns to climb to a better orbit for spacecraft deployment.

Friday’s mission’s Starlink satellites will fly in one in all 5 orbital “shells” utilized in SpaceX’s world web community. After reaching operational orbit, the satellites will enter business service and start transmitting broadband alerts to shoppers, who should purchase Starlink service and hook up with the community with a floor terminal offered by SpaceX.
