SpaceX has launched another group of Starlink satellites – Spaceflight Today

SpaceX launched 60 more Starlink relay internet platforms in orbit on Sunday as the company exploded network testing in Washington state and provided nearly 300 satellites launched since June without spacecraft failures.

Nine Merlin 1D engines fired and fired Falcon 9 rocket off pad 39A at the Kennedy Space Center in Florida at 8:25:57 am EDT (1225: 57 GMT) Sunday, marking Falcon’s 14th mission 9 dedicated to the deployment of satellites for SpaceX’s Starlink broadband network.

Petroleum-fueled engines throttle to produce 1.7 million pounds of thrust, driving the Falcon 9 rocket northeast from Florida Coast Space. Two and a half minutes later, the first stage booster shut down its engines and set off to begin its descent into the SpaceX drone ship “Of course I Still Love You” in the Atlantic.

Merlin’s second-stage single-engine engine ignited to continue the orbit mission, and the two-piece nose cover of the Falcon 9 changed in about three and a half minutes into flight.

The 15-story first stage booster nailed its landing on the SpaceX drone ship about 400 miles (630 kilometers) northeast of Cape Canaveral. This is the sixth space expedition and return for this particular follower – designated B1051 – after its debut on an unmanned Crew Dragon spacecraft flight in March 2019.

At the same time, the top phase of the Falcon 9 delivered 60 Starlink internet satellites in an initial orbit. The upper bouts featured two cutaways, for easier access to the higher frets. The lower bouts featured two cutaways, fore and aft; the lower bouts featured two cutaways, for easier access to the higher frets.

The 60 flat-panel satellites were separated from the rocket at 9:29 am EDT (1329 GMT) to complete SpaceX’s 70th consecutive successful mission. An upper-level camera showed 60 satellites – each with a volume of nearly one-ton tons – flying free on the Falcon 9 over the Indian Ocean.

“Great way to start on a Sunday,” said Andy Tran, a production supervisor at SpaceX who hosted the company’s webcast launch on Sunday.

SpaceX said two fairing recovery ships have caught the same halves of fairing since launching on Sunday as clamshells returned to Earth under parachutes. The net in one of the vessels surrendered while the fairing was fixed in orbit, but SpaceX said the ocean recovery team was OK.

Of the satellites launched on Sunday, SpaceX has placed 835 Starlink broadband relay stations in orbit, including prototypes that will not be used for commercial service. That extended SpaceX’s lead in operating the largest fleet of orbiting satellites.

The new Starlink spacecraft, built by SpaceX in Redmond, Washington, is expected to open solar panels and activate krypton ion thrusters to begin raising their altitude to approximately 341 miles (550 kilometers), which they will start providing broadband service.

SpaceX plans to launch an initial block of approximately 1,500 Starlink satellites in orbit 341 miles above Earth. The company, founded by billionaire Elon Musk, has approved regulation from the Federal Communications Commission to later install a fleet of up to 12,000 small Starlink broadband stations operating at Ku- frequencies. band, Ka-band, and V-band.

There are also preliminary plans for a larger fleet of 30,000 additional Starlink satellites, but a network of that size is not approved by the FCC.

SpaceX says the Starlink network – designed for low-latency internet services – is “in its infancy,” and engineers are constantly testing the system to collect latency data and speed tests. . In an FCC filing dated October 13, SpaceX said it has begun testing the beta of the Starlink network in many US states, and is providing internet connectivity to previously uneducated students in the provinces.

On September 28, the Washington Military Department announced it was using the Starlink internet service as emergency responders and residents in Malden, Washington, recovering from a fire that devastated much of the town.

Earlier this month, Washington government officials said the Hoh Tribe was starting to use the Starlink service. SpaceX recently said that Starlink ground terminals have recently been installed in an administrative building and about 20 private homes on the Hoh Tribe Reservation.

“We’re so far apart,” said Melvinjohn Ashue, vice chairman of the Hoh Tribe. “In the last eight years, I have felt we paddling the river with a spoon and almost no longer getting the internet on reservation.

“It seems like nowhere, SpaceX just came up and only catapulted us into the 21st century,” Ashue said October 7. “Our youth have done online education, participated in the videos. Tele-health will no longer be an issue, as will tele-mental health. “

In an FCC filing last week, SpaceX representatives wrote that the company has successfully launched and operated nearly 300 new Starlink spacecraft since June without fail.

“SpaceX continues to invest in the rapid expansion of the network, including launching up to 120 satellites a month and installing extensive ground-based infrastructure nationwide,” SpaceX told the FCC.

SpaceX appears to be on track to launch more than 120 satellites in October.

The company added 60 satellites to the Starlink network with the launch of Falcon 9 on October 6, and placed another 60 spacecraft Sunday. A Falcon 9 rocket is temporarily scheduled for lift from pad 40 at Cape Canaveral Air Force Station at 12:36 pm EDT (1636 GMT) Wednesday with another horde of Starlink satellites.
