The oldest Falcon 9 booster in SpaceX’s rocket launch fleet launched another 60 Starlink Internet satellites into space Tuesday with a launch from the historic pad 39A at NASA’s Kennedy Space Center in Florida.

With the launch of 60 satellites on Tuesday, SpaceX has sent 1,565 Starlink spacecraft into orbit to send broadband signals around the world, nearly nine times that of satellites among other companies’ constellations.

The 229-foot-tall (70 m) Falcon 9 rocket climbs from the Florida Space Station and blows through the sunny afternoon sky, flying on rails northeast from the Kennedy Space Center to place the Starlink Broadband Station. Another 60 places entered orbit.

The mission started at 3:01 p.m. EDT (1901 GMT) Tuesday as the Kerosene-powered Merlin 1D booster engine fired 9 to power the 1.2 million pound Falcon 9 launcher from the pad.

The Falcon 9 overtook the speed of sound for about a minute, then turned off the engine first and released the booster about two and a half minutes after the overhaul.

The 15-class booster stage, which assigns the B1049 in SpaceX’s fleet – continues to run towards the heights of the trajectory underneath the base and the non-rotating aerodynamic grid fins to help stabilize the rocket. Back to the atmosphere

The three booster Merlin engines were triggered to ignite the combustion in the inlet and the rocket’s center engine ignited for the landing combustion before the first stage extended outward and landed on the deck of the drone.

Landing about eight and a half minutes after the interstitial overhaul between the ninth voyage to space and the return of this booster, launched in September 2018, this reusable booster is the first step in the process. The oldest work in SpaceX’s inventory and nine launches and landings. Connect other supporters for the largest number of flights in the Falcon 9 fleet.

SpaceX plans to return the drone and Falcon 9 booster to Port Canaveral, Florida, from the recovery area a few hundred miles east of Charleston, South Carolina. The ground crew at Cape Canaveral are expected to inspect and tune the rocket for flight 10.

The Falcon 9’s second stage engine completed two burns to place 60 Starlink satellites in proper orbit for use, about 64 minutes after the top-facing takeoff showed 60 flat-screen satellites. A moon that flies without a rocket at an altitude of 182 miles (293 kilometers) in southern New Zealand.

The 573-pound (260 kg) satellite will be equipped with solar panels that generate power and power on krypton-fueled plasma thrusters to increase its altitude to 341 miles (550 km) to join the fleet. The rest of the star links

Tuesday’s launch marks the 100th successful Falcon 9 or Falcon Heavy mission without flight failures, a long line dating back to June 2015, marking the 91st successful mission. SpaceX’s rocket since the Falcon 9 rocket exploded during pre-flight testing at Cape Canaveral in September 2016, destroying Israeli launchers and communications satellites and damaging SpaceX’s launch pad.

The Starlink satellite is built on a SpaceX assembly line in Redmond, Washington.

The 1,565 Star Link satellites launched today consist of prototypes and failed spacecraft that fell out of orbit and burned down in the atmosphere, said Jonathan McDowell, astronomer and expert in space flight activity tracking. More than 1,400 Starlink satellites are currently in orbit, not counting the 60 spacecraft launched Wednesday night.

The Federal Communications Commission authorized SpaceX to install 12,000 Starlink satellites operating at Ku-band, Ka-band and V-band frequencies and at various altitudes and inclinations in Earth’s low orbit. The satellite is sending low-latency and broadband signals to users who subscribe to the Starlink beta test.

So far, almost all Starlink satellites launched by SpaceX have been operating in a 341 mile high orbit that is tilted 53 degrees to the equator.

“We have access to all over the world. But we don’t have full connections around the world, ”said SpaceX President and Chief Operating Officer Gwynne Shotwell at an industry conference last month. Around the world Then the plan after that was to add satellites to provide additional storage capacity. ”

Tuesday’s launch is the 25th Falcon 9 flight dedicated to hauling a working Starlink satellite known as version 1.0 into orbit and the 28th Falcon overall mission with Starlink payload. On the plane

In April, SpaceX sought FCC approval to operate the Starlink satellites at a lower than originally planned altitude, all between 335 miles (540 kilometers) and 354 miles (570 kilometers). The FCC approved the request. Last month

With commission approval, SpaceX will operate the first 4,408 satellites at an altitude of between 335 miles and 354 miles, rather than flying more than 2,800 of the spacecraft in an orbit that reaches 800 miles or 1,300 kilometers above Earth.

FCC approval allows SpaceX to begin sending Starlink satellites into polar orbit later this year. Polar orbiting satellites will provide complete global coverage of the Starlink network.

The updated Starlink network architecture has 1,584 satellites at an altitude of 341 miles (550 kilometers) and an inclination of 53 degrees, 1,584 satellites at 335 miles (540 kilometers) and an inclination of 53.2 degrees, 720 satellites at 354 miles (570 kilometers) and an altitude. Tilt 70 degrees and 520 satellites at 348 miles (560 kilometers) and a tilt of 97.6 degrees.

SpaceX retains regulatory approval to send more than 7,000 additional Starlink satellites in addition to the 4,408 spacecraft covered in the latest FCC approval.

The next Falcon 9 launch is scheduled for 02:42 AM EDT (0642 GMT) on Sunday from Pad 40 at Cape Canaveral Space Force Station, which features the next set of Starlink internet satellites.

Another Starlink mission is planned in mid-May with the launch of the Falcon 9 from pad 39A.
