SpaceX launched a novel — and colossal — business communications satellite into orbit late Saturday and set a brand new launch report for its Falcon 9 rocket on the identical time.
The Falcon 9 launched into orbit from Pad 39A at NASA’s Kennedy House Heart in Florida carrying 34 of SpaceX’s Starlink internet satellites and BlueWalker 3, a prototype satellite constructed by AST SpaceMobile that is billed as the biggest business communications array ever flown in space. Liftoff was at 9:20 p.m. EDT (0120 GMT) on Saturday night time (Sept. 10), with the Falcon 9 booster making some SpaceX historical past when it returned to Earth.

“It is a record-breaking 14th touchdown for this booster,” Jesse Anderson, a SpaceX manufacturing engineering supervisor, mentioned throughout live commentary (opens in new tab).
The mission additionally set just a few different data.
It was SpaceX’s first five-engine-burn mission to deploy payloads in orbit, in addition to the corporate’s heaviest rideshare payload ever. (BlueWalker 3 weighs a whopping 3,300 kilos (1,500 kilograms), Anderson mentioned.)
“One among our most advanced missions,” SpaceX CEO Elon Musk wrote of the flight on Twitter (opens in new tab).
Meet BlueWalker 3 from AST SpaceMobile
Whereas SpaceX’s main aim for Saturday’s launch was so as to add 34 new Starlink satellites to its rising constellation in orbit, AST SpaceMobile’s BlueWalker 3 satellite stood out for each its dimension and bold mission.
The satellite, which is able to measure 693 sq. ft (64 sq. meters) when totally unfolded, is the biggest business antenna array launched into space. Its mission: to check new know-how designed to offer world cellphone service on to customers from space. The aim is to fill in protection gaps and supply seamless high-speed telephone and knowledge service in underserved areas.
“The rationale why our satellite is giant is as a result of in an effort to talk with a low-power, low inner energy telephone, you simply want a big antenna on one aspect with numerous energy, and in order that’s a crucial a part of our infrastructure,” AST SpaceMobile Chief Technique Officer Scott Wisniewski informed House.com in an interview. “We expect that is actually necessary for speaking immediately with regulars handsets, with no change to the handset, with no further burdens on the consumer.”
It will likely be a number of weeks earlier than AST SpaceMobile instructions BlueWalker 3 to deploy its spring-loaded antenna, Wisniewski mentioned. Throughout that point, the corporate will carry out a sequence of well being checks to make sure the satellite is okay, he added.
AST SpaceMobile has partnered with 25 mobile service suppliers, 10 of which is able to take part within the firm’s deliberate six-month shakedown cruise of BlueWalker 3 to check its capabilities throughout six continents all over the world. These companions embody suppliers like Vodaphone, Rakuten Cellular and Orange, and a possible attain of 1.8 million telephone customers, Wisniewski mentioned. Earlier this summer time, the corporate acquired an FCC license to test BlueWalker 3’s service in Texas and Hawaii in america.
As a way to present full protection, AST SpaceMobile will want multiple satellite. “That is the end result of form of the R&D stage of our firm earlier than we go on to manufacturing satellites subsequent yr,” Wisniewski mentioned.
The corporate plans to observe BlueWalker 3 with 5 operational satellites in 2023. It in the end goals to construct a constellation of no less than 100 large satellites to offer full protection.
AST SpaceMobile is not alone in its pursuit of mobile phone protection from space. The corporate Lynk International is engaged on an identical venture and Elon Musk unveiled final month that SpaceX is teaming up with T-Mobile to offer mobile service with its Starlink satellites.
Due to their dimension, AST SpaceMobile’s satellites could also be seen to skywatchers from the bottom and a few astronomers have criticized the plan for its potential influence on telescope observations from the bottom, based on a New Scientist report (opens in new tab). If that criticism sounds acquainted, that is as a result of it is one that’s dogged SpaceX’s own Starlink constellation as soon as that firm started launching dozens of them at a time.
A rocket reuse report as Starlink grows
About 8.5 minutes after launching the BlueWalker 3 and Starlink satellites, the primary stage of SpaceX’s Falcon 9 rocket returned to Earth for a pinpoint touchdown on the corporate’s droneship A Shortfall Of Gravitas within the Atlantic Ocean. The touchdown set a brand new report for the variety of launches for a Falcon 9 booster.
Earlier than Saturday’s flight, the Falcon 9 stage launched eight totally different Starlink missions, in addition to SpaceX’s first astronaut take a look at flight for NASA (referred to as Demo-2) in Could 2020; the ANASIS-2 satellite for South Korea in July 2020; the uncrewed CRS-21 cargo mission to the Worldwide House Station for NASA in December 2020, in addition to the Transporter 1 and Transporter 3 rideshare missions in January 2021 and January 2022, respectively.
When Elon Musk unveiled the workhorse Falcon 9 Block 5 booster in 2018, he mentioned SpaceX’s aim was to fly them no less than 10 occasions. With every subsequent flight, the corporate has pushed its boundaries for rocket reusability as a part of its effort to decrease the price of spaceflight.
Equally, SpaceX has continued to develop the scale of its Starlink constellation, in addition to the variety of nations and areas of protection in recent times. In August, Royal Caribbean announced (opens in new tab) will probably be utilizing Starlink aboard all of its cruise ships by 2023, with SpaceX already providing providers for RVs, boats and houses all over the world.
The corporate has launched greater than 3,200 satellites since 2019, with hundreds extra to come back. SpaceX plans to finish its preliminary constellation with 12,000 Starlinks in orbit and has utilized for permission to spice up that as much as 30,000 satellites.
On Sunday, Sept. 11, SpaceX plans to launch yet one more Starlink mission. That flight, which is able to carry 54 Starlink satellites, is scheduled to launch from House Launch Advanced 40 on the Cape Canaveral Space Force Station in Florida at 10:53 p.m. EDT (0253 GMT). You’ll watch that launch reside on House.com at liftoff time.
Saturday’s launch marked the forty first of the yr for SpaceX. It was the corporate’s 179th launch general.
