SpaceX CEO Elon Musk talks Starship space telescopes, artificial gravity
In his latest batch of tweets, SpaceX CEO Elon Musk says that the company is already thinking about the many potential ways its next-generation Starship launch vehicle could be used in space.
Already, ideas publicly touted by the SpaceX CEO range from using Cargo Starships to clean up space debris with its mouth-like payload bay to a stripped-down, expendable variant of the rocket to rapidly send massive spacecraft throughout the solar system. Now, Musk says that SpaceX has also considered tethering Starships together in space to create a form of artificial gravity for passengers on multi-month journeys between planets, as well as the possibility of turning entire Starships into all-in-one orbital observatories a magnitude more powerful than Hubble.
Apparently invoked during discussions with astrophysicist and Nobel laureate Saul Perlmutter, at least parts of the physics community are already considering the possibilities offered by using Starship as a sort of foundation or spacecraft bus that could carry and operate vast scientific payloads. While Starship has already been officially floated several times as a serious contender for launch services for major future missions, this concept would instead see Starship function as the spacecraft itself.
As of 2021, Starship has yet to reach space or orbit once, but SpaceX isn’t far from that milestone. Eventually, perhaps just a few years from now, Starship will have successfully launched to and operated in orbit dozens or even hundreds of times and become a mature and reliable spacecraft.
At that point, it wouldn’t be out of the question to entrust Starships themselves to serve as long-lasting scientific spacecraft, exploiting a ‘bus’ that could offer abundant power, propulsion, thermal management, navigation, and communications capabilities to any ‘hosted’ payloads. That includes extensively modifying Starships on the ground to create vast space observatories, among numerous other possibilities.
Given Starship’s low production cost, 9-meter (~30 ft) diameter, and nominal ability to deliver at least 100 metric tons (~220,000 lb) of payload to low Earth orbit (LEO), it’s not inconceivable that ships could be outfitted with massive telescopes and scientific instruments. Perhaps more importantly, drastically reduced payload constraints (more than an order of magnitude relative to the Hubble or James Webb telescopes) could allow major innovation in spacecraft/instrument design, radically lowering costs while still improving reliability, redundancy, and performance.
Meanwhile, Musk says that SpaceX has also considered tethering crewed Starships together and spinning them around the center of that tether to create artificial gravity for crewmembers on months-long journeys between Earth, Mars, and other planets. Among fan communities, the tethered gravity concept has been circulating ever since SpaceX first announced Starship in 2016. Loosely researched by NASA and other institutions for decades, no real experimental efforts – save for a single halting test during a 1960s Gemini mission – have ever been pursued.
For Starship, orbital refueling could easily allow SpaceX to cut crewed Earth-Mars transit time to 100 days or less – subjecting astronauts to significantly less time in microgravity than those that crew the International Space Station (ISS). The value proposition of artificial gravity on 3-month cruises is likely substantially less clear-cut given the far-reaching complexity and modifications required to make such a system functional and make Starships compatible.
Regardless, Musk rather cryptically says that SpaceX has considered the concept, though he didn’t elaborate on whether the company ultimately decided to drop the subject or pursue it further.

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.
