SpaceX successfully deployed 60 more Starlink Internet satellites into orbit on Saturday, continuing record launching caddies while engineers will assess concerns with the Falcon 9 rocket engine delaying other missions, including the International Space Station’s next crew flight.
The Star0 Starlink satellites exploded from pad at 0 at Cape Canaveral Air Force Station on Saturday morning: 31:31:33:44. The mission was delayed from Thursday to give engineers on the upper stage of the Falcon 9 rocket time to evaluate the camera mera problem.
The nine-kerosene-powered Merlin 1D engine delivered a 229-foot-tall (70-meter) launch into the sky on an accidental route north of Cape Canaveral.
The first phase of the rocket shut down its engines and separated from the mission by a minute, while a controlled descent began at a pinpoint landing on a floating platform, parked about 400 miles (630 kilometers) northeast of the launch site.
The touchdown came just moments before landing completed a third trip to space and designated a reusable Falcon 9 booster for the B1060 – and 60 Starlink satellites in the upper stage of the rocket into orbit of initial parking.
The Falcon 9’s two-piece payload didn’t try to catch the ferries as they fell back to Earth under a parachute. At the company’s most recent launch on October 18, one of SpaceX’s Fair Recovery ships damaged the nasal cone structure by mesh.
Instead, SpaceX dispatched a boat from its fleet to receive observations, innovations and ferring structures for potential use in future flights from the Atlantic Ocean.
Following the shores of the Atlantic Ocean, Europe, and the Middle East, the Falcon 9’s upper stage briefly injected its single engine at 44 degrees in a near circular orbit at an altitude of about 170 miles (275 kilometers). ) With a 53 degree inclination towards the equator.
All 60 satellites flattened on top of the Falcon 9 rocket for launch were separated from the phase above EDT (1634 GMT) at 12:34 p.m. Flat-panel satellites in the live video feed from the rocket were reverberating from the scene as it flew south of Tasmania.
SpaceX’s Falcon 9 rocket took off from Cad Canaveral at 11:30 a.m. EDT (1531 GMT) with 60 more Starlink Internet satellites orbiting through the clouds in the autumn sky.

The satellites built by SpaceX in Reshmond, Washington, were expected to orbit at an operational altitude of more than 100 miles (50 ar0 kilometers) and begin moving their krypton ion thrusters at an operational altitude of 1 mile (505050 kilometers). Other Starlink relay stations, to beam broadband Internet signals in the most populous world.
SpaceX plans to launch an initial block of about 1,500 Starlink satellites in orbit 341 miles above Earth. Founded by billionaire Elon Musk, the company has regulatory approval from the Federal Communications Commission to operate a fleet of 12,000 small Starlink broadband stations operating in low-band, Ka-band and V-band frequencies.
There are also initial plans for a large fleet of 30,000 additional Starlink satellites, but a network of that size has not been authorized by the FCC.
SpaceX says the Starlink network – designed for low-latency Internet service – is still in its infancy, and engineers continue to test the system to collect delayed data and speed tests. In a Oct. 13 filing with the FCC, SpaceX said it has begun beta testing of the Starlink network in several U.S. states, and is providing Internet connectivity to previously vulnerable students in rural areas.
On September 28, the Washington Military Department announced that it was using the Starlink Internet service because emergency responders and residents of Malden, Malden, had recovered from a forest fire that destroyed much of the city.
Earlier this month, Washington government officials said the Hoh Tribe was starting to use the Starlink service. SpaceX said it has recently installed about 20 private homes on the Starlink Ground Terminal and Ho Tribe reservations on the administrative building.
The list of Starlink satellites maintained by Jonathan McDowell, a global astronomer who monitors global spaceflight activity, indicates that 53 of the Starlink satellites have deorbited since their launch, mainly tests launched last year. Two other satellites have failed and another 20 have stopped maneuvering, leaving about 820 spacecraft likely to remain operational, according to McDowell.
Since Oct 6, SpaceX has shot 180 Starlink satellites into orbit on three dedicated Falcon 9 rocket missions. It has more satellites than the entire constellation powered by the planet, which has the second largest fleet of spacecraft in orbit.
As of this week, Planet had about 150 active skysets and Dove Earth-imaging satellites in its fleet, a company spokesman said.
SpaceX continues to launch Starlink while engine issue delays another mission
Three Starlink missions were launched on the Falcon 9 rocket this month, as SpaceX delayed the study of the issue with Merlin engines in other launches that led to the U.S. launch. The Falcon 9 countdown was canceled by the Army’s GPS navigation satellite.
Elon Musk, founder and CEO of SpaceX, tweeted after the abortion that the countdown had stopped after T-minus 2 seconds, referring to equipment used on the rocket’s nine Merlin first-stage main engines, “unexpected pressure increase in turbomachine gas generator”. The gas generators on the Merlin 1D engine run the turbopumps of the engines.
NASA announced on October 10 that SpaceX’s first operational crew would delay the Dragon Flight from the Kennedy Space Center to the International Space Station’s flight engineers from October 31 to mid-November to give them time to study and resolve the engine issue. .
Kathy Luders, head of NASA’s Human Spaceflight Programs, tweeted on October 21 that the space agency was making “a lot of good progress” on testing the SpaceX engine. Understand the unpredictable behavior observed during a recent non-NASA launch. “
As for SpaceX, it is too early to report a conclusion at this time The test continues to validate what is believed to be the most credible reason, ”Luders tweeted.
He wrote that SpaceX is replacing an engine on the Falcon 9 rocket assigned to the Crew-Dragon mission – known as Crew-1 – and an engine on the Falcon 9 booster, which will be launched next month by the Vandenberg Air Force to launch a US-European ocean satellite satellite. Has been designated for. Base, California.
The engines are changing the behavior displayed during their ground testing which was similar to the “early start behavior” recorded during the canceled GPS launch on Oct. 201.
The launch of the Sentinel-6 Michael Freelich oceanographic satellite is scheduled to take place on November 10 from California, Luders said.
“We are still working for Crew-1 for the beginning of mid-November,” he added. “We need a few days between Sentinel-6 and Crew-1 to complete data reviews and check performance. Most importantly, we will fly all our missions when we are ready.
The Crew-1 mission will unveil four astronauts to embark on a six-month voyage to the International Space Station. It follows a two-man crew dragon test flight that began in May0 and completed the first orbital flight of astronauts from U.S. soil since the astronauts retired in 2001, with a successful return to Earth on August.
16 Oct Qt. In a press briefing, the NASA manager said that NASA, U.S. Engineers from Space Force and SpaceX are jointly investigating the engine problem that arose during the October 2 countdown.
“I can tell you that an incredible amount of data has been taken into account to include members of our commercial crew program, including the upcoming Falcon Flight,” said Tim Dunn, NASA’s launch director for the Sentinel-6 Michael Freelich mission.
In addition to testing at Cape Canaveral’s launch base, SpaceX removed engines from the Falcon 9 rocket for GPS missions and returned to the company’s testing facility in McGregor, Texas for detailed testing and reviews.
“We’ve learned a lot,” Dunn said. “Depending on the engine installed on the various rockets we will have some hardware effects going forward. The GPS mission is clearly affected. The NASA Crew-1 mission is affected. At Sentinel-6, we are looking for engines that are in our first phase. We’re working on what we have to do, but today we have a way forward that allows us to do what we need riverwork and still maintain the November 10 launch date. “
