SpaceX almost ready to launch NASA asteroid impact spacecraft
Update: The NASA official quoted saying that the DART spacecraft had arrived at Vandenberg on September 27th appears to have been incorrect and may have accidentally confused the arrival of an “advance team” with the arrival of the spacecraft itself.
Science communicator and author David Brown was reportedly on-site on September 29th to watch as the DART spacecraft was carefully packaged for the journey from Maryland’s Johns Hopkins University to its California launch site, obviously making a VSFB arrival two days prior impossible. Nevertheless, now stowed inside an environmentally-controlled shipping container, DART should still arrive at Vandenberg within the next week or two.
Revealed as a side note during live coverage of the space agency’s successful Landsat-9 launch, NASA says that the Double Asteroid Redirect Test (DART) spacecraft has arrived at Vandenberg Space Force Base (VSFB) ahead of a SpaceX Falcon 9 launch less than two months from now.
Weighing around 690 kg (~1500 lb) at liftoff, NASA confirmed that the DART spacecraft and its Italian-built LICIACube smallsat companion are on track to launch out of SpaceX’s VSFB SLC-4E pad on a Falcon 9 rocket no earlier than (NET) November 23rd, 2021. Carrying its small passenger, DART will then make a beeline for binary asteroid pair Didymos and Dimorphos. Respectively measuring around 800 and 170 meters across, DART will ultimately target the smaller of the pair and accelerate to an impact velocity of ~6.6 km/s (4 mi/s or Mach 19).
DART will then rely on a built-in telescope and closed-loop targeting software to home in on and smash into Dimorphos, ultimately using the tiny asteroid system as a sort of sandbox to test theories of asteroid redirection that might one day help humans prevent catastrophic impacts with Earth.
Originally targeted to launch in June 2021 when NASA awarded SpaceX the $69M launch contract (now up to $73M after two small changes) in April 2019, DART has slipped approximately five months in the 2.5 years since when a few minor technical issues arose late in development. Impressively, almost none of those delays appear to have been caused by the COVID-19 pandemic, which cannot be said for a number of other NASA, US military, and commercial satellites and launches.
Set to cost a total of ~$250M including launch services, DART’s main purpose is to determine how exactly an asteroid behaves when impacted by a high-velocity spacecraft. Whereas depictions of asteroid “redirection” in popular science fiction tend to lean towards the “send an arsenal of nuclear bombs” approach, the reality is that bombing most asteroids and comets large enough to threaten the surface of Earth would add uncertainty more than it would mitigate the threat.
Given how little is actually known about the physical characteristics of asteroids, attacking one with a bomb could simply separate a killer asteroid into any number of smaller, still-deadly asteroids – now spread into a shotgun-like pattern of undetectable fragments instead of one large, visible object. Instead, most modern science on the matter now believes that the best route to redirection is a combination of early detection and a (relatively) low-energy impact. A bit like the concept of the butterfly effect, a relatively gentle impact (still akin to 2.5 tons of TNT with DART) years or decades in advance could drastically change the trajectory of the threatening asteroid or comet, causing it to miss Earth. DART won’t directly prevent an asteroid from impacting Earth but hitting the asteroid moon of a larger asteroid should effectively magnify the effect the tiny impact has on its orbital characteristics.
DART will also serve as a technology demonstration, debuting both satellite-class roll-out solar arrays and NASA’s self-developed NEXT-C electric propulsion system. With any luck, it will also help scientifically prove that humans could use a similar approach to save ourselves from a catastrophic space impact event years or decades from now.

Brazil Supreme Court orders Elon Musk and X investigation closed
The decision was issued by Supreme Court Justice Alexandre de Moraes following a recommendation from Brazil’s Prosecutor-General Paulo Gonet.
Brazil’s Supreme Federal Court has ordered the closure of an investigation involving Elon Musk and social media platform X. The inquiry had been pending for about two years and examined whether the platform was used to coordinate attacks against members of the judiciary.
The decision was issued by Supreme Court Justice Alexandre de Moraes following a recommendation from Brazil’s Prosecutor-General Paulo Gonet.
According to a report from Agencia Brasil, the investigation conducted by the Federal Police did not find evidence that X deliberately attempted to attack the judiciary or circumvent court orders.
Prosecutor-General Paulo Gonet concluded that the irregularities identified during the probe did not indicate fraudulent intent.
Justice Moraes accepted the prosecutor’s recommendation and ruled that the investigation should be closed. Under the ruling, the case will remain closed unless new evidence emerges.
The inquiry stemmed from concerns that content on X may have enabled online attacks against Supreme Court justices or violated rulings requiring the suspension of certain accounts under investigation.
Justice Moraes had previously taken several enforcement actions related to the platform during the broader dispute involving social media regulation in Brazil.
These included ordering a nationwide block of the platform, freezing Starlink accounts, and imposing fines on X totaling about $5.2 million. Authorities also froze financial assets linked to X and SpaceX through Starlink to collect unpaid penalties and seized roughly $3.3 million from the companies’ accounts.
Moraes also imposed daily fines of up to R$5 million, about $920,000, for alleged evasion of the X ban and established penalties of R$50,000 per day for VPN users who attempted to bypass the restriction.
Brazil remains an important market for X, with roughly 17 million users, making it one of the platform’s larger user bases globally.
The country is also a major market for Starlink, SpaceX’s satellite internet service, which has surpassed one million subscribers in Brazil.

FCC chair criticizes Amazon over opposition to SpaceX satellite plan
Carr made the remarks in a post on social media platform X.
U.S. Federal Communications Commission (FCC) Chairman Brendan Carr criticized Amazon after the company opposed SpaceX’s proposal to launch a large satellite constellation that could function as an orbital data center network.
Carr made the remarks in a post on social media platform X.
Amazon recently urged the FCC to reject SpaceX’s application to deploy a constellation of up to 1 million low Earth orbit satellites that could serve as artificial intelligence data centers in space.
The company described the proposal as a “lofty ambition rather than a real plan,” arguing that SpaceX had not provided sufficient details about how the system would operate.
Carr responded by pointing to Amazon’s own satellite deployment progress.
“Amazon should focus on the fact that it will fall roughly 1,000 satellites short of meeting its upcoming deployment milestone, rather than spending their time and resources filing petitions against companies that are putting thousands of satellites in orbit,” Carr wrote on X.
Amazon has declined to comment on the statement.
Amazon has been working to deploy its Project Kuiper satellite network, which is intended to compete with SpaceX’s Starlink service. The company has invested more than $10 billion in the program and has launched more than 200 satellites since April of last year.
Amazon has also asked the FCC for a 24-month extension, until July 2028, to meet a requirement to deploy roughly 1,600 satellites by July 2026, as noted in a CNBC report.
SpaceX’s Starlink network currently has nearly 10,000 satellites in orbit and serves roughly 10 million customers. The FCC has also authorized SpaceX to deploy 7,500 additional satellites as the company continues expanding its global satellite internet network.

Tesla Energy gains UK license to sell electricity to homes and businesses
The license was granted to Tesla Energy Ventures Ltd. by UK energy regulator Ofgem after a seven-month review process.
Tesla Energy has received a license to supply electricity in the United Kingdom, opening the door for the company to serve homes and businesses in the country.
The license was granted to Tesla Energy Ventures Ltd. by UK energy regulator Ofgem after a seven-month review process.
According to Ofgem, the license took effect at 6 p.m. local time on Wednesday and applies to Great Britain.
The approval allows Tesla’s energy business to sell electricity directly to customers in the region, as noted in a Bloomberg News report.
Tesla has already expanded similar services in the United States. In Texas, the company offers electricity plans that allow Tesla owners to charge their vehicles at a lower cost while also feeding excess electricity back into the grid.
Tesla already has a sizable presence in the UK market. According to price comparison website U-switch, there are more than 250,000 Tesla electric vehicles in the country and thousands of Tesla home energy storage systems.
Ofgem also noted that Tesla Motors Ltd., a separate entity incorporated in England and Wales, received an electricity generation license in June 2020.
The new UK license arrives as Tesla continues expanding its global energy business.
Last year, Tesla Energy retained the top position in the global battery energy storage system (BESS) integrator market for the second consecutive year. According to Wood Mackenzie’s latest rankings, Tesla held about 15% of global market share in 2024.
The company also maintained a dominant position in North America, where it captured roughly 39% market share in the region.
At the same time, competition in the energy storage sector is increasing. Chinese companies such as Sungrow have been expanding their presence globally, particularly in Europe.
