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.

Tesla Full Self-Driving’s newest behavior is the perfect answer to aggressive cars
According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.
Tesla Full Self-Driving appears to have a new behavior that is the perfect answer to aggressive drivers.
According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.
With FSD’s constantly-changing Speed Profiles, it seems as if this solution could help eliminate the need to tinker with driving modes from the person in the driver’s seat. This tends to be one of my biggest complaints from FSD at times.
A video posted on X shows a Tesla on Full Self-Driving pulling over to the shoulder on windy, wet roads after another car seemed to be following it quite aggressively. The car looks to have automatically sensed that the vehicle behind it was in a bit of a hurry, so FSD determined that pulling over and letting it by was the best idea:
Tesla appears to be implementing some sort of feature that will now pull over if someone is tailgating you to let the car by
Really cool feature, definitely get a lot of this from those who think they drive race cars

We can see from the clip that there was no human intervention to pull over to the side, as the driver’s hands are stationary and never interfere with the turn signal stalk.
This can be used to override some of the decisions FSD makes, and is a great way to get things back on track if the semi-autonomous functionality tries to do something that is either unneeded or not included in the routing on the in-car Nav.
FSD tends to move over for faster traffic on the interstate when there are multiple lanes. On two-lane highways, it will pass slower cars using the left lane. When faster traffic is behind a Tesla on FSD, the vehicle will move back over to the right lane, the correct behavior in a scenario like this.
Perhaps one of my biggest complaints at times with Full Self-Driving, especially from version to version, is how much tinkering Tesla does with Speed Profiles. One minute, they’re suitable for driving on local roads, the next, they’re either too fast or too slow.
When they are too slow, most of us just shift up into a faster setting, but at times, even that’s not enough, see below:
What has happened to Mad Max?
At one point it was going 32 in a 35. Traffic ahead had pulled away considerably https://t.co/bjKvaMVTNX pic.twitter.com/aaZSWmLu5v

There are times when it feels like it would be suitable for the car to just pull over and let the vehicle that is traveling behind pass. This, at least up until this point, it appears, was something that required human intervention.
Now, it looks like Tesla is trying to get FSD to a point where it just knows that it should probably get out of the way.

Tesla Megapack powers $1.1B AI data center project in Brazil
By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.
Tesla’s Megapack battery systems will be deployed as part of a 400MW AI data center campus in Uberlândia, Brazil. The initiative is described as one of Latin America’s largest AI infrastructure projects.
The project is being led by RT-One, which confirmed that the facility will integrate Tesla Megapack battery energy storage systems (BESS) as part of a broader industrial alliance that includes Hitachi Energy, Siemens, ABB, HIMOINSA, and Schneider Electric. The project is backed by more than R$6 billion (approximately $1.1 billion) in private capital.
According to RT-One, the data center is designed to operate on 100% renewable energy while also reinforcing regional grid stability.
“Brazil generates abundant energy, particularly from renewable sources such as solar and wind. However, high renewable penetration can create grid stability challenges,” RT-One President Fernando Palamone noted in a post on LinkedIn. “Managing this imbalance is one of the country’s growing infrastructure priorities.”
By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.
“The facility will be capable of absorbing excess electricity when supply is high and providing stabilization services when the grid requires additional support. This approach enhances resilience, improves reliability, and contributes to a more efficient use of renewable generation,” Palamone added.
The model mirrors approaches used in energy-intensive regions such as California and Texas, where large battery systems help manage fluctuations tied to renewable energy generation.
The RT-One President recently visited Tesla’s Megafactory in Lathrop, California, where Megapacks are produced, as part of establishing the partnership. He thanked the Tesla team, including Marcel Dall Pai, Nicholas Reale, and Sean Jones, for supporting the collaboration in his LinkedIn post.

Starlink powers Europe’s first satellite-to-phone service with O2 partnership
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools.
Starlink is now powering Europe’s first commercial satellite-to-smartphone service, as Virgin Media O2 launches a space-based mobile data offering across the UK.
The new O2 Satellite service uses Starlink’s low-Earth orbit network to connect regular smartphones in areas without terrestrial coverage, expanding O2’s reach from 89% to 95% of Britain’s landmass.
Under the rollout, compatible Samsung devices automatically connect to Starlink satellites when users move beyond traditional mobile coverage, according to Reuters.
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools. O2 is pricing the add-on at £3 per month.
By leveraging Starlink’s satellite infrastructure, O2 can deliver connectivity in remote and rural regions without building additional ground towers. The move represents another step in Starlink’s push beyond fixed broadband and into direct-to-device mobile services.
Virgin Media O2 chief executive Lutz Schuler shared his thoughts about the Starlink partnership. “By launching O2 Satellite, we’ve become the first operator in Europe to launch a space-based mobile data service that, overnight, has brought new mobile coverage to an area around two-thirds the size of Wales for the first time,” he said.
Satellite-based mobile connectivity is gaining traction globally. In the U.S., T-Mobile has launched a similar satellite-to-cell offering. Meanwhile, Vodafone has conducted satellite video call tests through its partnership with AST SpaceMobile last year.
For Starlink, the O2 agreement highlights how its network is increasingly being integrated into national telecom systems, enabling standard smartphones to connect directly to satellites without specialized hardware.
