SpaceX Dragon spacecraft returns NASA cargo to Earth after six weeks in space
A SpaceX Cargo Dragon 2 spacecraft has safely returned to Earth after delivering several tons of NASA supplies to the International Space Station (ISS).
A little over six weeks after Falcon 9 launched SpaceX’s 26th Commercial Resupply Services 2 (CRS2) mission for NASA, Dragon departed the ISS on January 9th. Efficiently lowering its orbit with several small Draco thrusters took about 36 hours, and reusable Dragon 2 capsule C211 eventually slowed to the point that it began impacting Earth’s atmosphere. Using its ablative heat shield like a brake pad, Dragon slowed from a velocity of 7.5 kilometers per second (16,800 mph) to about 155 meters per second (~350 mph) before beginning parachute deployment.
At 5:19 am on January 11th, the Dragon capsule gently splashed down off the coast of Tampa, Florida, and was quickly secured by a SpaceX recovery ship. Once onboard, the capsule was opened up, and cargo fresh from orbit was loaded onto a helicopter as quickly as possible. That system – primarily created to rapidly transport astronauts back to NASA medical facilities – also means that scientists can get access to their recovered ISS experiments just a handful of hours after Cargo Dragon splashes down.

Some of the scientific investigations returned by Dragon include:
Deep space radiation protection: A vest designed to protect astronauts from high doses of radiation caused by unpredictable solar particle events is returning to Earth after months of testing. Crew members wore the Astrorad vest while performing daily tasks and provided feedback about how easy it is to put on, how it fits and feels, and the range of motion possible while wearing it. The vest’s developers plan to use that feedback to improve design of the garment, which could provide radiation protection for astronauts on Artemis missions to the Moon.
Air, water, plants: XROOTS used hydroponic (water-based) and aeroponic (air-based) techniques to grow plants without soil or other growth media. Researchers collected video and still images to evaluate growth chambers through the plant life cycle from seed germination through maturity. The plant chambers are returning to Earth for additional analysis. Similar techniques could be used to produce crops for future space missions and to enhance cultivation and food security for the benefit of people on Earth.
Bioprospecting in space: Bioprospecting is the process of identifying plants and animals that may contain substances with potential for use as drugs, biochemicals, and more. Previous studies found that space can cause genetic and physiological changes that could result in microbes yielding such materials. Rhodium Microgravity Bioprospecting-1 studied a way to search for these microbes. The science chambers and temperature logger from the investigation are returning to Earth for further examination.”

SpaceX’s second-generation Cargo Dragon spacecraft is nearly identical to Crew Dragon. Both are made up of two main parts: a reusable capsule and an expendable ‘trunk.’ The Dragon 2 trunk is a tube-like carbon fiber composite structure covered by a skin of curved solar arrays and radiators. It can also hold several tons of unpressurized cargo.
Dragon’s capsule holds a pressure vessel, environmental control systems (ECLSS), all 16 Draco maneuvering thrusters, propellant tanks, docking systems, and an ablative heat shield. In the case of Crew Dragon, the capsule is also outfitted with windows, crew seats, hand control, and SuperDraco launch abort thrusters. Both Cargo and Crew Dragon capsules represent the vast majority of the total spacecraft cost and can be recovered, refurbished, and reflown in as little as four months.
NASA is SpaceX’s only Cargo Dragon customer. January 11th’s recovery marked the completion of CRS2 Spx-26, SpaceX’s 25th successful ISS resupply mission since 2012. After adding more contracts last year, NASA has arrangements for at least nine more Dragon 2 resupply missions stretching into 2026 or 2027. NASA also signed contracts for eight Crew Dragon astronaut launches in 2022 and has nine missions on contract between now and the late 2020s or 2030.
While Falcon 9 infamously failed during the June 2015 launch of CRS-7, every Dragon that has ever reached orbit has been recovered in one piece. Spx-26 was Dragon’s 38th mission overall and 35th consecutively successful recovery from orbit.

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.
