SpaceX launches 60 extra Starlink satellites on 100th Falcon 9 flight – Spaceflight Now

The 100th flight of a Falcon 9 rocket delivered 60 satellites to orbit for SpaceX’s Starlink community Tuesday night time, including one other constructing block to a deliberate fleet of hundreds of solar-powered space-based relay stations to beam broadband connectivity around the globe.

The profitable mission late Tuesday additionally set a brand new file for SpaceX’s rocket reuse program — one which might be damaged once more inside months if SpaceX maintains its feverish launch cadence. For the primary time, a reusable Falcon 9 booster accomplished its seventh journey to house and again on Tuesday night time’s flight.

The Falcon 9 rocket fired its 9 kerosene-fueled Merlin 1D engines and roared off pad 40 at Cape Canaveral Air pressure Station at 9:13:12 p.m. EST Tuesday (0213:12 GMT Wednesday). The 229-foot-tall (70-meter) launcher darted by means of a damaged cloud layer over the pad and rocketed towards the northeast from Cape Canaveral to line up with the mission’s focused orbital airplane inside the Starlink community.

The rocket’s 15-story first stage booster dropped away from the Falcon 9 higher stage about two-and-a-half after liftoff, setting a course for a managed landing on SpaceX’s drone ship “Of Course I Nonetheless Love You” positioned a number of hundred miles northeast of Cape Canaveral within the Atlantic Ocean,

The booster — designated B1049 in SpaceX’s rocket stock — reignited its heart engine for a braking maneuver simply earlier than landing, then prolonged a touchdown gear earlier than settling onto the deck of the drone ship. The apparently flawless touchdown punctuated the seventh mission of the B1049 car, making it SpaceX’s “fleet chief.”

Elon Musk, SpaceX’s founder and CEO, has mentioned the latest model of the Falcon 9 booster may fly 10 occasions with none main refurbishment, and maybe 100 occasions with periodic overhauls.

Together with its reused first stage booster, the Falcon 9 launched with a recycled clamshell-like payload shroud, half of which flew on two earlier missions. The opposite half of the fairing was a veteran one prior launch.

Two restoration vessels have been dispatched to sea to retrieve the fairing halves from Tuesday night time’s mission after they parachuted again to Earth from house.

Whereas the booster and fairing shells descended again to Earth, the Falcon 9’s higher stage guided the 60 flat-panel Starlink satellites right into a switch orbit inclined 53 levels to the equator. Round 15 minutes after liftoff, the higher stage launched retention rods to permit the stack of 60 spacecraft to fly free from the rocket over the North Atlantic Ocean.

The Falcon 9 aimed to position the satellites into an elliptical orbit ranging between 132 miles (213 kilometers) and 227 miles (366 kilometers). A member of SpaceX’s launch staff confirmed on a mission audio loop that the rocket achieved an on-target orbital insertion.

The launch was beforehand scheduled Saturday night time, then delayed to Sunday, when SpaceX known as off a launch try attributable to considerations about “mission assurance.” SpaceX bypassed a launch alternative Monday attributable to a forecast of poor circumstances within the Falcon 9 booster’s offshore touchdown zone, setting the stage for Tuesday’s countdown.

Tuesday night time’s launch was the 23rd SpaceX mission of 2020, extending the corporate’s file cadence of flights. The earlier file for essentially the most SpaceX launches in a yr was 21 missions in 2018.

The quarter-ton Starlink satellites, constructed by SpaceX in Redmond, Washington, have been anticipated to unfurl power-generating photo voltaic arrays and prime their krypton ion thrusters to start elevating their orbits to an operational altitude of 341 miles (550 kilometers), the place they may be a part of greater than 800 different Starlink relay stations to beam broadband web alerts throughout many of the populated world.

With the launch Sunday, SpaceX has deployed 955 Starlink satellites into orbit.

SpaceX plans to function an preliminary block of round 1,500 Starlink satellites in orbits 341 miles above Earth. The corporate, based by billionaire Elon Musk, has regulatory approval from the Federal Communications Fee to finally subject a fleet of as much as 12,000 small Starlink broadband stations working in Ku-band, Ka-band, and V-band frequencies.

There are additionally preliminary plans for an excellent bigger fleet of 30,000 further Starlink satellites, however a community of that dimension has not been approved by the FCC.

SpaceX says the Starlink community — designed for low-latency web service — has entered a beta testing part in a number of U.S. states and Canada.

“Final month, SpaceX launched its “Higher Than Nothing Beta” take a look at program,” the corporate mentioned in a submit on its web site. “Service invitations have been despatched to a portion of those that requested availability updates on and who stay in serviceable areas. A pair weeks in the past, Canada granted Starlink regulatory approval and final week SpaceX rolled out the service to components of components of southern Canada.”

The “invitation-only” beta testing program is concentrated on testing Starlink connectivity in rural and distant areas within the northern United States and southern Canada, mentioned Kate Tice, a SpaceX engineer who co-hosted the corporate’s launch webcast Tuesday night time.

“As we launch extra satellites, set up extra floor stations, and enhance our networking software program, information pace, latency, and uptime will all enhance dramatically,” Tice mentioned.

SpaceX tasks latency on the Starlink community will fall to round 16 to 19 milliseconds by mid-2019, Tice mentioned.

“At our present tempo, we anticipate to increase our beta in a notable method very early subsequent yr, within the late January-February timeframe,” she mentioned.
