CAPE CANAVERAL, Fla. — A SpaceX Falcon 9 rocket lit up the predawn sky early this morning (March 11) because it carried a brand new batch of 60 Starlink web satellites into orbit, earlier than nailing its touchdown on a floating platform at sea.
The 2-stage Falcon 9 booster lifted off from Area Launch Advanced 40 right here at Cape Canaveral Area Pressure Station at three:13 a.m. EST (0813 GMT). About eight.5 minutes later, the rocket’s reusable first stage returned to Earth for its sixth touchdown, touching down on certainly one of SpaceX’s drone ships. The floating platform, referred to as “Simply Learn the Directions,” was stationed out within the Atlantic Ocean, about 400 miles (630 kilometers) downrange.
It was a transparent night time in Florida for the mission’s second try. The launch was initially deliberate to happen on Monday night time (March 9) however was pushed again so SpaceX may conduct extra prelaunch checkouts. Climate forecasters on the U.S. Area Pressure’s 45th Climate Squadron predicted a 90% likelihood of favorable circumstances for launch this morning, and Mom Nature delivered.

This newest liftoff marked SpaceX’s seventh mission of 2021 and the corporate’s 21st 60-satellite Starlink launch total. It starred one of many higher identified Falcon 9 first phases within the fleet — B1058.
Emblazoned with a now-sooty NASA worm brand, B1058 is the booster that delivered two NASA astronauts to the Worldwide Area Station (ISS) in Could of final yr, returning orbital human spaceflight to U.S. soil with SpaceX’s Demo-2 mission.
The veteran launcher additionally delivered a cargo Dragon spacecraft to the ISS, a communications satellite tv for pc for South Korea’s navy and the most satellites ever launched on a single mission (Transporter-1). At this time, B1058 carried its second stack of Starlink satellites.
The predawn spectacle marked the 110th total flight of a Falcon 9 rocket and the 56th reflight of a Falcon 9 first stage. It was the sixth mission for this specific booster, and SpaceX set a brand new document for quickest turnaround time for a rocket with this many flights beneath its belt.
B1058 final flew on Jan. 24, and it blasted off once more from the identical launch pad this morning, simply 45 days later; the earlier document for such a veteran booster was 59 days.
SpaceX depends closely on its fleet of veteran rockets, which have enabled the corporate to maintain up with its launch ambitions. Nevertheless, SpaceX has all the time pressured that, whereas booster restoration is helpful, the principle purpose of every mission is to efficiently ship the payload to area.
The corporate recovered a primary stage for the primary time in 2015, when a Falcon 9 booster touched down on terra firma at one of many firm’s Florida touchdown pads. Ever since, SpaceX has been striving to higher perceive the restoration course of and the way a lot put on and tear every launch places on the rocket.
With every restoration try, the corporate has been in a position to refine its course of and cut back occasions between flights. SpaceX founder and CEO Elon Musk has stated that his long-term imaginative and prescient includes rockets that resemble airplanes, within the sense that they raise off, land, refuel and raise off once more briefly order.
Musk has stated, for instance, purpose of SpaceX is to launch, land, after which launch and land the identical rocket once more inside 24 hours — a milestone that has not but been reached.
Whereas SpaceX makes touchdown rockets look simple, a latest anomaly exhibits that it is not all the time a slam dunk. On Feb. 15, the corporate broke a 24-booster restoration streak when a Falcon 9 first stage, designated B1059, failed to land on a drone ship within the Atlantic Ocean after launching a distinct batch of Starlink satellites into orbit.
The mishap was attributed to “warmth injury,” with firm officers elaborating on that in a latest teleconference. Benji Reed, SpaceX’s senior director for human spaceflight, stated that one of many booster’s protecting engine covers failed, permitting sizzling gases from the engine to leak into locations it wasn’t purported to, inflicting an engine to shut down during flight. This shutdown finally brought about the rocket to overlook its mark on the drone ship.

SpaceX upgraded its Falcon 9 rocket again in 2018, giving the car a collection of enhancements, together with a extra sturdy thermal safety system, titanium grid fins and a extra sturdy interstage, to facilitate reuse. The upgrades enabled the rocket to refly a number of occasions with few refurbishments in between.
The corporate stated that the Falcon 9 we see right this moment might be able to flying a minimal of 10 occasions with little to no refurbishment between flights and as many as 100 occasions total earlier than retirement. However such numbers will not be set in stone. As a substitute, these targets might be extra of a suggestion that adjustments as the corporate refines its refurbishment course of.
SpaceX has two boosters which are near the 10-mission milestone, having flown a document eight occasions, and it is potential we may see one or each of these hit double digits this yr. The corporate has large ambitions for 2021, with a purpose of launching a complete of 40 missions from its California and Florida launch pads.
This morning’s mission marked the 76th SpaceX booster touchdown thus far, and the 19th for “Simply Learn the Directions.”
To get better its returning boosters, SpaceX makes use of two large floating touchdown platforms — “Of Course I Nonetheless Love You” and “Simply Learn the Directions” — along with its touchdown pads, which permit the corporate to launch and land extra rockets. Usually, the drone ships see a lot of the motion, because it takes extra gas reserves to make all of it the way in which again to land than it does to return down at sea.
“Simply Learn the Directions” is the newer of the 2 ships. Initially stationed out in California, the ship was moved to the East Coast in 2020, to assist with the elevated launch cadence.
SpaceX has been planning a 3rd drone ship for a while now, and it is potential that ship would service the West Coast as the corporate goals to extend launches from its amenities at Vandenberg Air Pressure Base in California. There isn’t any anticipated completion date on the third ship, however a latest firm job opening for a drone ship restoration engineer suggests it might be someday within the close to future.
Increasing the megaconstellation
With this morning’s profitable liftoff, SpaceX has now launched greater than 1,200 Starlink satellites into orbit, together with some which are not operational. The corporate has deliberate for its preliminary Starlink constellation to be 1,440 robust however has sought approval for tens of thousands extra. There are various extra launches coming as SpaceX fills out this rising megaconstellation.
The corporate launched its Starlink program with one main purpose: to attach the globe. To that finish, SpaceX designed a fleet of flat-paneled broadband satellites that fly over Earth, offering web protection to customers around the globe.
SpaceX not too long ago began taking preorders for its public rollout. Potential customers may join the service through a web site, pay a deposit after which be notified when protection is obtainable of their space.
The rollout is on a first-come, first-serve foundation whereas the corporate is conducting an in depth worldwide and home beta-testing part. Prematurely of this launch, SpaceX rolled out service to Germany and New Zealand and is working to develop its present service in the UK.
However that is not all. Current filings point out that the corporate is looking for permission to develop its providers to transferring automobiles, together with planes, boats and RVs. In response to Musk, the present Starlink consumer terminals, which facilitate entry to the satellites overhead, are too large to put in cars, so for now, it is focusing on larger automobiles.

Falling fairings
SpaceX’s dynamic fairing-catching boat duo, GO Ms Tree and GO Ms Chief, are nonetheless sidelined, present process upkeep in Florida’s Port Canaveral. As such, SpaceX deployed two of its Dragon restoration vessels, GO Searcher and GO Navigator, to the deliberate restoration web site.
The 2 boats acquired upgrades that enable them to scoop fairing items out of the water. The payload fairing is a clamshell-like piece of designed to guard satellites as their rocket travels by means of the ambiance. SpaceX fairings are composed of two halves. At a delegated level after launch, the 2 items jettison and fall again to Earth.
Traditionally, the payload fairing has been a one-and-done piece of , discarded within the ocean after every mission. However SpaceX has been working to develop its reusability efforts and has had success recovering and reflying fairing items.
For this mission, the lively fairing (the half that has the motors that jettison it from the rocket) has flown as soon as earlier than, and the passive (or different half) has flown twice earlier than. As soon as recovered from the ocean, SpaceX inspects and refurbishes every fairing piece.
Up subsequent for SpaceX is one other Starlink mission, which may launch as quickly as this weekend. The corporate can also be making ready for its subsequent astronaut mission, Crew-2, which is scheduled to launch from NASA’s Kennedy Area Heart in Florida no sooner than April 22.
