CAPE CANAVERAL, Fla. — A SpaceX Falcon 9 rocket launched a brand new batch of 60 Starlink web satellites into orbit late Monday (Feb. 15), however failed to stay its touchdown on a floating platform at sea.
The 2-stage Falcon 9 booster, topped with the 60 broadband spacecraft, lifted off from Space Launch Complex 40 here at Cape Canaveral Area Drive Station at 10:59 p.m. EST (0359 GMT on Feb. 16). Roughly 9 minutes later, the rocket’s first stage returned to Earth to aim its sixth touchdown on SpaceX’s drone ship “Of Course I Nonetheless Love You” within the Atlantic Ocean,” however missed its goal.
“It does appear to be we didn’t land our booster on Of Course I Nonetheless Love You tonight,” SpaceX manufacturing engineer Jessica Anderson mentioned throughout stay launch commentary. “It’s unlucky that we didn’t get well this booster however our second stage continues to be on a nominal trajectory.”
SpaceX prefers to get well its Falcon 9 rocket phases for reuse, however the firm has additionally mentioned repeatedly that delivering a flight’s payload to orbit is all the time the first mission.

One in every of SpaceX’s frequent fliers powered this newest Starlink mission into orbit. The booster, dubbed B1059, beforehand ferried two totally different SpaceX Dragon cargo resupply missions to the Worldwide Area Station — CRS-19 in Dec. 2019 and CRS-20 in March of 2020 — a Starlink mission final June, an Earth-observing satellite tv for pc for Argentina (SAOCOM-1B in August 2020), and a spy satellite tv for pc for the usgovernment as a part of the NROL-108 mission in December.
Tonight’s launch was the primary of two deliberate Starlink liftoffs inside every week; one other 60 satellites are scheduled to take flight early as Wednesday (Feb. 17) on a distinct Falcon 9. The short succession is because of the truth that SpaceX just lately needed to shuffle round its deliberate Starlink missions as each climate and hardware-related points offered a little bit of a problem.
This mission, dubbed Starlink 19, moved ahead after SpaceX’s 18th Starlink mission blasted off on Feb. 4. Each flights leapfrogged Starlink 17, which was initially slated to launch on Feb. 1. Scheduled to fly on one in all SpaceX’s two record-setting frequent fliers, B1049, the mission was delayed a number of occasions and is now anticipated to blast off simply after midnight on Feb. 17.
Throughout the preliminary mission planning, SpaceX focused launching two Starlink missions simply hours aside — a primary for the area coast since 1966 when a Gemini rocket was adopted by an Atlas Agena simply 99 minutes later. Finally the twin missions didn’t occur, however in an unprecedented transfer for the period of economic spaceflight, the Jap Vary (the company that oversees launches alongside the East Coast) approved two missions to launch in fast succession.
This can be a feat we may even see occur at a later date, particularly as extra launch suppliers grow to be lively and increasingly launches blast off from Florida. Final 12 months, there have been a file 31 launches for the 12 months, and 2021 may very well be even busier because the 45th Area Wing is getting ready for a minimum of 40 missions.
Double the launches
Initially slated to launch on Sunday night time, SpaceX had to stand down due to poor weather on the launch web site. Thunder storms rolled throughout Florida this previous weekend, stopping the flight from taking off.
Circumstances improved Monday and the Falcon 9 was in a position to fly, marking the fifth launch of the 12 months for SpaceX and enabling the corporate to look ahead to its subsequent mission. One other stack of Starlink satellites is about to blast off from SpaceX’s different Florida launch web site at Pad 39A of NASA’s Kennedy Area Heart right here.
The mission was additionally the 108th flight total for SpaceX’s workhorse Falcon 9. It could have marked the 75th rocket touchdown for the corporate if the Falcon 9 had caught its landing.
To get well 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. Sometimes the drone ships see a lot of the motion because it takes extra gas reserves to land again in land than it does to land at sea.
The model of Falcon 9 we see at this time, is a souped-up model of its predecessors, able to flying a number of occasions with solely minor refurbishments in between. That is attributable to a collection of upgrades Falcon 9 obtained in 2018 — together with a extra strong thermal safety system, titanium grid fins and a extra sturdy interstage — which facilitate reuse.
As such, this fleet of extra succesful rockets has allowed SpaceX to fly extra missions. The corporate launched a file 26 occasions in 2020, with 22 of these flights on veteran rockets.
The corporate goals to surpass that file in 2021, because it hopes to launch a minimum of 40 rockets between its California and Florida launch amenities.
Constructing a megaconstellation
With tonight’s launch success, SpaceX now has greater than 1,000 Starlink satellites into orbit. And there are lots of extra launches coming; SpaceX’s preliminary Starlink constellation will include 1,440 satellites, and the corporate has sought approval for tens of thousands extra.
The corporate launched its large constellation, which outnumber every other constellation at present in orbit, with an overarching purpose of connecting the globe.
To that finish, SpaceX designed a fleet of flat paneled broadband satellites that may fly over the Earth, offering customers throughout the globe with web protection.
Tonight’s flight comes simply days after SpaceX started providing preorders to the general public. Final week, the corporate opened up its web site to potential prospects on a first-come, first-serve foundation whereas the corporate is conducting an in depth worldwide and home beta-testing part.
Potential customers can order gear and join the service, which may take six months or extra to grow to be out there, in accordance with the web site.
SpaceX started its “higher than nothing” beta testing part in 2020, as the corporate let its workers put the burgeoning satellite tv for pc service by way of its paces.
Firm founder and CEO Elon Musk has mentioned there would must be at between 500-800 Starlink satellites in orbit earlier than protection may begin to roll out. As soon as that milestone was achieved, the corporate began testing its new service.
Early studies from workers indicated that the service labored, and even enabled streaming of a number of excessive definition applications on the identical time. Quickly after, SpaceX invited customers to start out testing its service, whereas persevering with to launch increasingly satellites.
The corporate was granted permission to start out rolling out its service to customers within the U.Ok. earlier this 12 months, and even snagged its first Canadian buyer final December.
The Pikangikum First Nation was ready to make use of the service to attach its members, and supply entry to education schemes in addition to telemedicine and extra.

GO Ms. Tree and GO Ms. Chief, SpaceX’s two net-equipped boats are additionally stationed out within the Atlantic. The dynamic duo will get well the rocket’s nostril cone (in any other case generally known as a payload fairing), after the 2 items fall again to Earth.
Geared up with navigation software program and particular parachutes, the 2 halves of the protecting shell will information themselves again to Earth, and probably be scooped out of the water after splashdown.
Often SpaceX does catch the falling fairings in mid air, however that’s dependent upon winds and climate. Restoration efforts are usually introduced by SpaceX 45 minutes after liftoff.
