SpaceX’s Falcon 9 wins launch of an asteroid-attacking NASA spacecraft

Published

on

Just minutes before SpaceX began fueling Falcon Heavy for its commercial launch debut, NASA announced that the company had won a contract for its Double Asteroid Redirection Test (DART) mission, to be launched by Falcon 9 for the low cost of $69M.

Designed to cost less than $250M total, the DART mission will aim to be as light and fast as possible, using a dedicated Falcon 9 to send the ~600 kg (~1300 lb) spacecraft and its Italian companion cubesat on an ~11 million kilometer (~7M mi) journey to the binary asteroid Didymos. The ultimate purpose of DART is to effectively prove out both technologies and physics that could be used in the future to defend Earth from asteroids known to be on a collision course.

If all goes as planned during DART’s imminent design review milestones and hardware integration, Falcon 9 could launch the spacecraft towards the Didymos asteroid system in June 2021 for an October 2022 arrival. That “arrival” would involve DART impacting Didymos-B – the smaller of the pair at 163 m (535 ft) across – at a relative velocity of more than 6 km/s (3.7 mi/s). Nicknamed Didymoon, Didymos-B effectively orbits Didymos-A. At that speed, the ~600 kg probe will create an impact with the equivalent explosive force of nearly two and a half tons of TNT, the purpose of which is to determine just how much the sheer kinetic energy of impact can modify a small body’s orbit around the main asteroid.

Estimates from the spacecraft’s mission managers expect Didymoon’s orbit to be shifted by about 1% as measured by the time it takes to orbit Didymos-A, from ~11.9 hours to ~11.8 to 12.0 hours. This is a very small change but one that should – in theory – be easily measurable by telescopes on Earth, despite the fact that Didymoon has been estimated to have a mass of approximately 3.5 million metric tons (7.6 billion pounds), approximately seven million times heavier than DART. In short, NASA is going to functionally bomb an asteroid moon to see if humans might be able to use kinetic impactors to gently ‘boop’ threatening space objects off of the offending trajectory years or even decades in advance.

Despite the inherently destructive, single-use nature that DART’s impactor status bestows, current plans thankfully include an Italian cubesat known as LICIACube. The small copassenger will deploy two days before impact to fully exploit the scientific value of DART’s demise with high-quality photos of the event and aftermath. LICIACube will be traveling the same speed and thus won’t be able to enter orbit around the asteroid system, but a European Space Agency (ESA) mission known as Hera plans to do just that in the mid-2020s to better characterize Didymos and the crater (hopefully) made by DART.

Aside from the mission itself, DART serves as a technology demonstration platform for NASA. It will mark the first in-space use of the NASA-built NEXT-C ion thruster and powerpack, as well as the first standalone use of Roll-Out Solar Array (ROSA) deployment mechanism (shown above being tested on the ISS). Even more intriguing is a proposed transformational solar array planned at one point for DART, a flexible combination of advanced solar cells (~33% efficient) and mirror concentrators that could feed a spacecraft five times as much power for a given solar array area and distance from the sun. It’s unclear whether this will make it into DART’s final design but it still appears to be on the table as of January 2019. According to the contracted manufacturer, DART’s solar array will produce ~6.6 kW, while rough estimates suggest that the solar array will have an area of 16 m^2 (170 ft^2). Relative to the simplicity of the deployment mechanism and small size of DART (~600 kg total), this is an incredible amount of accessible power.

Getting to orbit

For NASA’s SpaceX launch contract, the agency will pay just $69M, barely 10% above Falcon 9’s bare-minimum list price of $62M. It’s safe to assume that the timing of the contract award – days after SpaceX abruptly dropped an official protest of ULA winning a ~$150M NASA contract – might not be coincidence. Regardless, SpaceX’s decision to bid so low for a NASA launch does lend some serious credence to the company’s protest that ULA’s contract for the mission – NASA’s LUCY asteroid explorer – was “vastly more [expensive]” than the bid SpaceX submitted.

Weighing just ~600 kg (~1300 lb) wet, DART could end up launching with additional copassengers on Falcon 9, although there is a precedent set by NASA’s ~360 kg TESS and Taiwan’s Formosat-5 for SpaceX giving tiny spacecraft dedicated launches. Additionally, it’s possible that DART will launch on a flight-proven Falcon 9 Block 5 rocket, given the likelihood that NASA will have certified flight-proven SpaceX vehicles for almost any launch by 2021.

Elon Musk’s surprise addition to the X Takeover lineup has fans talking

Elon Musk will join Saturday’s X Takeover at Giga Texas for a live virtual interview.

Elon Musk will join X Takeover at Giga Texas on Saturday for a live virtual interview, according to Sawyer Merritt, who shared the news late Thursday. Musk will not be on stage in Austin. The conversation is set to stream for free on the @teslaownersSV account on X.

Organizers had kept expectations in check. In a September update, Tesla Owners Silicon Valley said Musk had appeared at the event twice before but was not promising a third appearance, even as fans hoped he would walk the Giga Texas grounds in person. A virtual spot matches 2024, when Musk gave a surprise interview of about an hour to the crowd in San Luis Obispo, as Teslarati reported at the time.

This year’s edition is a first in several ways. It is the first X Takeover held outside California and the first at a Tesla facility, with tickets selling out in eight days. Tesla provides the venue, but the event is produced independently by Tesla Owners Silicon Valley. The main event runs from 10 a.m. to 6 p.m. CT, followed by a drone and light show at 9 p.m. Maye Musk is the keynote speaker, Franz von Holzhausen is set for a virtual keynote, and Nicki Minaj is the special guest. Joe Tegtmeyer, whose drone footage Teslarati used to track the Optimus factory steel frame at Giga Texas, is also on the speaker list.

Musk’s interview topics have not been revealed, but the backdrop is busy. Tesla doubled its Cybercab fleet in Austin in late September, and last week Musk explained why Robotaxi hours only moved from 10 p.m. to 11 p.m.. Merritt also reported Thursday that Texas DMV records now show 319 registered Cybercabs, up from 169. NHTSA’s deadline for Tesla’s sworn answers on Cybercab certification is October 30, and Tesla reports third quarter earnings on October 21.

Fans who cannot make it to Austin can watch the livestream on X. Musk tends to say more in unscripted settings than he does in prepared remarks, which is the reason this one is worth having open on Saturday.

It’s official: SpaceX takes aim at Verizon, AT&T, and T-Mobile

SpaceX is buying 800 MHz spectrum from Grain to turn Starlink Mobile into a carrier.

SpaceX has agreed to buy a nationwide block of low band wireless spectrum, a deal the company says will let Starlink Mobile operate as a full US carrier rather than a satellite add-on for someone else’s network.

The company announced the agreement on X on Thursday afternoon, saying it will “pave the way for @Starlink to become a major mobile carrier in the US.” The seller is Grain Management, a private investment firm that confirmed in a statement that SpaceX will acquire 100% of its nationwide 800 MHz portfolio. That covers up to 14 MHz of paired spectrum in the 817 to 824 MHz and 862 to 869 MHz bands. Neither side disclosed a price, and the deal still needs FCC approval.

Grain only recently picked up the licenses itself. It bought the portfolio from T-Mobile in a transaction that closed in August, paying cash plus its own 600 MHz spectrum. Rival AST SpaceMobile had been testing satellites on the same bands before SpaceX stepped in.

SpaceX said its 2 GHz spectrum will handle high bandwidth capacity, while the new 800 MHz layer “ensures Starlink Mobile’s signal penetrates through obstacles, such as walls, and can provide service to customers’ devices even when they are in buildings.” The company added that most existing phones already support the band, so customers would not need new hardware to use it.

That 2 GHz spectrum came from SpaceX’s EchoStar acquisition last year, which gave the company exclusive S band rights in the US and global Mobile Satellite Service licenses. The Grain spectrum is different in an important way: it is tailored for service from ground towers, not satellites. SpaceX said that combination would make Starlink Mobile “the first network operator to deploy both satellite and terrestrial spectrum.”

The announcement also follows a key regulatory win. Earlier this week, the FCC approved SpaceX’s plan to deploy 15,000 second generation Starlink Mobile satellites, which the company has said will carry up to 100 times the data density of the current system, as Teslarati previously reported.

Shares of AT&T, Verizon and T-Mobile fell in extended trading after the announcement. T-Mobile is currently SpaceX’s launch partner for Starlink Mobile in the US, which makes its position the most complicated of the three.

SpaceX has not been subtle about its plans. During the company’s August earnings call, President and COO Gwynne Shotwell said she expected Starlink Mobile to win over customers from the major carriers. “I anticipate us to be able to acquire quite a few of their customers because I think our service will be better,” she said, pointing to dead zone coverage and resilience during disasters. Shotwell also described plans for low cost cellular base stations that could pair with existing Starlink dishes.

SpaceX has targeted 2027 for deployment of its next generation Starlink Mobile satellites, with upgraded service expected by the end of that year. The FCC review of the Grain deal now determines when the terrestrial half of that network can come online.

Trump presents Elon Musk with National Medal of Science, calls him “modern-day Thomas Edison”

Elon Musk holds the National Medal of Science alongside President Donald Trump at the “Science: A New Golden Age” summit in Washington on October 8, 2026.

Elon Musk now has the highest honor the U.S. government gives to scientists and engineers. President Donald Trump presented him with the National Medal of Science on Thursday at the White House’s “Science: A New Golden Age” summit, held at the Institute of Peace in Washington, according to the White House.

Trump called Musk a “national treasure” and “our modern-day Thomas Edison.” “Few Americans in history have done more to advance America’s national interest than Elon in one field after another,” the president said. He also described Musk as an “industrial titan, brilliant engineer and one of the greatest technology founders to ever live.”

The official citation credits Musk “for engineering achievements of extraordinary ambition and scale that have pushed the frontiers of space exploration, intelligent systems, communications, and beyond, renewing American technological leadership and opening a new chapter in American manufacturing.” Tesla is not named in it, but “intelligent systems” and “American manufacturing” cover a lot of ground that Tesla and the Terafab chip project occupy.

Google co-founder Sergey Brin, Nvidia CEO Jensen Huang and AMD CEO Lisa Su received the same medal. Microsoft CEO Satya Nadella and Dell Technologies CEO Michael Dell were given the National Medal of Technology and Innovation. It was the first time Trump has handed out either award in his two terms. As Teslarati noted when the list was first reported on Wednesday, the National Science Foundation says 529 people have received the Medal of Science since Congress created it in 1959.


The ceremony closes a loop that opened in 2025, when Musk left DOGE and criticized the “Big Beautiful Bill,” sparking a public feud. Al Jazeera noted that Musk was the largest contributor to Trump’s 2024 campaign, and CNBC reported that all of the honorees have given financially to Trump or Republican causes in some form. The reconciliation has moved quickly in recent weeks. Musk sat at Trump’s left at the September 29 White House AI lunch, was named to help lead the Pentagon’s Project Meridian study on the future of warfare, and adopted the administration’s “super intelligence” wording when he said SpaceXAI will become SpaceXSI.

For Tesla and SpaceX shareholders, the practical question is what the closer relationship means for federal approvals. Tesla’s Robotaxi and Cybercab expansion depends on national autonomy rules, and SpaceX’s Starship and Starlink plans run through the FAA, FCC and NASA. Thursday’s ceremony did not change any of that directly.
