SpaceX on Sunday sent another batch of 53 Starlink internet satellites into orbit aboard a Falcon 9 rocket, the company’s 33rd mission this year and its sixth launch in July. Liftoff took place at 09:38 EDT (1338 GMT) from Platform 39A at NASA’s Kennedy Space Center in Florida.

The Falcon 9 booster has landed on a SpaceX drone parked in the Atlantic Ocean northeast of Cape Canaveral.

The rocket headed northeast from Kennedy Space Center, aiming to send a broadband relay station into orbit between 144 miles and 210 miles (232 x 338 kilometers). About 15 minutes after takeoff, 53 flat-pack satellites were deployed from the upper stages of the Falcon 9.

With Sunday’s mission, called Starlink 4-25, SpaceX launched 2,957 Starlink Internet satellites, including prototypes and test units that are no longer operational. Sunday’s launch is SpaceX’s 53rd mission dedicated primarily to putting the Starlink internet satellite into orbit.

Stationed inside the firing chamber at the Kennedy Launch Control Center, SpaceX’s launch team began loading a very cold, viscous kerosene and liquid oxygen booster into the 229 ft (70 m) Falcon 9 in T-minus 35 minutes.

Compressor helium was also injected into the rocket in the last half hour of the countdown. In the final seven minutes before takeoff, the main engine of the Falcon 9 Merlin is thermally adjusted for flight in a process known as “chilldown”. The Falcon 9 guidance and field protection systems are also configured to launch.

After liftoff, the Falcon 9 rocket tested 1.7 million pounds of thrust – generated by nine Merlin engines – for guidance in the Northeast Atlantic.

The missile exceeded the speed of sound in about a minute, and then shut down its nine main engines two and a half minutes after takeoff. The boost stage is fired from the top stage of the Falcon 9, then pulses from cold gas control thrusters and extended titanium grille fins to help propel the vehicle back into the atmosphere.

Two ballistic burns slowed the missile as it landed on the drone ship “A Shortfall of Gravitas” about 400 miles (650 kilometers) after takeoff of about eight and a half minutes.

The Starlink 4-25 Mission Boost rocket, known as the B1062, has launched on its eighth flight into space. It began with the launch of the US military’s GPS navigation satellite in November 2020, and the entire Inspiration 4 and Axiom-1 crewed missions in September 2021 and in April this year.

Recently, a booster rocket took off with the Egyptian geostationary communications satellite Nilesat 301 on June 8.

The first-stage landing on Sunday’s mission came moments after the Falcon 9’s second-stage engine failed to send the Starlink satellite into orbit. The 53rd spacecraft, built by SpaceX in Redmond, Washington, separated from a Falcon 9 rocket at T+ plus 15 minutes and 24 seconds.

The hold bar is removed from the Starlink payload stack, allowing the flat-pack satellite to fly freely into orbit from the Falcon 9’s upper stage. The spacecraft will rotate and power the solar array through 53 automatic activation stages, then use a Krypton-fueled ion engine to propel it into its operational orbit.

The purpose of the Falcon 9 guidance computer is to position the satellite in an elliptical orbit at an orbital inclination of 53.2° at the equator. The satellite will use the onboard thrust to do the rest of the work to achieve a circular orbit of 335 miles (540 kilometers) above Earth.

The Starlink satellite will fly in one of five orbital “skins” in different directions for SpaceX’s global internet. Once it reaches its operational orbit, the satellite will enter commercial service and begin broadcasting broadband signals to consumers, who can purchase Starlink services and from the network through ground stations provided by SpaceX. can join.

Including the Starlink 4-25 mission on Sunday, SpaceX this month launched six Falcon 9 rockets in just 17 days, deployed 251 Starlink Internet satellites in five flights, while also sending a Dragon cargo capsule to the International Space Station.
