Elon Musk and SpaceX won’t be stopped along the road to Mars
If one is to take anything at all away from Elon Musk’s update to SpaceX’s planetary colonization strategy on September 29, it ought to be the tangible and undeniable progress the company has made with real, Mars-focused hardware development.
To take Musk at his word, the general atmosphere pervading the two relevant programs is one of extreme success and confidence. Raptor, the powerful methane-oxygen rocket engine intended to be the workhorse for any larger launch vehicle, has conducted dozens (42, to be specific) of successful hot fires at SpaceX’s McGregor, Texas testing facilities. These ranged from a handful of seconds all the way to 100 seconds in duration, and Musk made it explicitly clear that the only limiting factor to test duration was the size of the tanks of propellant available to fuel the engine. Of crucial importance is the fact that the engine being tested in Texas is a subscale prototype, and is not representative of the final engine. However, SpaceX has since shrunk the final target for operational Raptors, and this means that the current scale is not far off from the final thrust figure. The prototype Raptor is believed to have a thrust of approximately 1,000 kN (Kilonewtons), with slides from Musk’s 2017 presentation pointing to a full scale thrust of 1700 kN, far closer to becoming real than the 3,000 kN figure given at the 2016 IAC.

Possibly even more significant is the reported success SpaceX has had with the construction and stress testing of a full-scale carbon fiber liquid oxygen tank, which was tested to a very eventful destruction on Washington state’s Puget Sound. Fans closely followed this series of tests, but information was scarce and the general consensus was that the tank had failed unintentionally during those tests. The fact that Musk claimed that the 12 meter diameter tank was “successfully tested” at high pressures, as well as the confidence he expressed about a uniquely capable “carbon fiber matrix”, suggest that SpaceX have leaped over one of biggest potential hurdles of their larger vehicle plans. Carbon fiber propellant tanks have the potential to make rockets significantly lighter and thus more efficient, particularly if no internal liner of metal is needed to ensure the safety of those carbon fiber tanks. One might remember the difficulties SpaceX had with supercool liquid oxygen, culminating in the Amos-6 mishap that saw carbon fiber helium tanks clash with SpaceX’s then-new supercooled propellant procedures.

Through many challenging mistakes, SpaceX has learned the hard way that extra care must be taken when mixing carbon fiber and liquid oxygen. The telltale sign that SpaceX has, however, successfully learned from those mistakes can be found in the company’s aspiration to begin construction of the first BFR cargo ship as early as April of 2018, barely six months from today. Time will tell if they can maintain that aggressive schedule and launch two Mars-bound cargo ships in 2022. The company’s incontrovertible success with the development of Raptor engines and carbon fiber propellant tanks bode extremely well for the future of their planetary colonization efforts.

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.
