SpaceX aborts Starship launch after Raptors produce too much thrust
Update #3: SpaceX CEO Elon Musk says that Starship prototype SN10 automatically aborted a 2:15 pm CST (UTC-6) launch attempt after the rocket determined that its three Raptor engines were producing too much thrust.
Instead of scrubbing for the day, Musk says that SpaceX will instead increase the flight computer’s thrust limits and try again as early as 4:30 pm CST – still well before today’s window closes at 6:30 pm. SpaceX ended its webcast but will start a second webcast a few minutes prior to the next launch attempt.
Update #2: As of Wednesday morning, SpaceX has officially confirmed that Starship is on track for a third high-altitude launch and ‘bellyflop‘-style landing attempt sometime later today.
As of 11am CST (UTC-6), FAA approval is in hand, weather is encouraging, Starship prototype serial number 10’s (SN10) flaps have been unchained, and SpaceX has cleared the launch site – all signs that the rocket’s launch attempt is imminent. Much like SN8 and SN9 coverage, SpaceX says it will make a public livestream of SN10’s launch available to the public “a few minutes” before liftoff. Stay tuned and follow along with NASASpaceflight’s live coverage in the meantime.
Update: SpaceX has asked Boca Chica Village residents to prepare to evacuate the area as early as Wednesday morning for Starship’s third high-altitude launch and landing attempt.
The odds of things going so wrong that a Starship launch could actually end with a prototype impacting at or near the Village and the handful of non-employee holdouts still residing there are minuscule. However, FAA safety regulations and SpaceX’s contingent launch license mean that evacuations are now a routine part of Starship’s high-altitude flight tests since Starship SN8 took the first step beyond short hops. While undeniably inconvenient for the few remaining residents, today’s evacuation notice – short of an official SpaceX.com confirmation – does serve as the ultimate sign that Starship SN10’s first launch attempt is firmly scheduled on Wednesday, March 3rd.
With FAA approval in hand, weather rapidly improving, and the latest rocket prototype seemingly raring to go, the stars are aligning for SpaceX’s third high-altitude Starship launch and first triple-engine landing attempt.
As of March 1st, publicly-available FAA “temporary flight restrictions” (TFRs) and weather forecasts both agree that SpaceX is currently preparing to launch Starship serial number 10 (SN10) as early as Wednesday afternoon CST (UTC-6), March 3rd. Barring surprises, that gives SpaceX a healthy three-day period to account for any potential technical or weather-related delays.
Originally scheduled as early as the last week of February, unspecified delays pushed Starship SN10’s launch debut schedule into March. In general, the vehicle’s path to flight has been much smoother than Starship SN8 and SN9, both of which ran into hardware bugs and opaque FAA licensing issues. With Starship SN10, the FAA approved SpaceX’s “modified” launch license well before the company was ready for flight – and even before the rocket had attempted its first static fire.
Unlike Starships SN8 and SN9, both of which took anywhere from 6-10 weeks to go from rolling off the factory floor to preparing for their first launch attempts, SN10’s first launch attempt appears likely to occur less than five weeks after the rocket arrived at the launch site. The sequential improvements in efficiency and reliability between those three prototypes is a fundamental part (or goal, at least) of SpaceX’s iterative development process.
Still, Starship SN10’s preflight flow wasn’t completely free of drama and SpaceX ultimately put the rocket through a second triple-Raptor static fire after the first test revealed an issue with one of those engines. SpaceX swapped that faulty engine out in record time and fired up SN10 again less than 48 hours after test #1, seemingly producing more satisfactory results the second time around.
Unlike its predecessors, SN10 will also debut a new triple-engine approach to landing, aiming to increase redundancy and boost the odds of a successful touchdown even if one of the Starship’s three Raptors fail during a last-second flip maneuver. Building on the failures of SN8 and SN9, it’s safe to say that SN10 has the best shot yet at sticking the landing.
TFRs show that two earlier launch windows on Monday and Tuesday (March 1st and 2nd) were canceled, leaving only the Wednesday, March 3rd airspace closure request still open. Wednesday was then backed up with two alternate windows on Thursday and Friday not long after.
Hardware-wise, Starship SN10’s cherry-on-top (an explosives-based flight termination system or FTS) was installed on February 28th. In the event that Starship loses control and strays past a certain point outside of its approved trajectory, that FTS would explode, breaching the rocket’s propellant tank, triggering vehicle breakup, and thus preventing it from harming the local populace. All told, SpaceX confirmation of a Wednesday launch attempt – and another official webcast – should be imminent. Stay tuned!

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.
