Update: For unknown reasons, possibly including technical issues or subpar weather, SpaceX has scrubbed upgraded Starship prototype SN15’s planned Friday launch debut.

Weather is set to significantly improve on Sunday, with good conditions persisting until Tuesday in current forecasts. Barring a weekend launch, the likes of which hasn’t been seen in more than half a year, Starship SN15’s next available launch window will likely be sometime on Monday, May 3rd.

Right in the nick of time for a high-altitude flight test scheduled as early as Friday, April 30th, SpaceX has secured an FAA license to launch Starship prototype SN15 and simultaneously received an FCC permit to operate a Starlink dish installed on the rocket.

The two-month FCC permit is primarily a luxury that will allow SpaceX to experiment with the utility of adding Starlink satellite internet connectivity to an active launch vehicle. The FAA license, however, is an essential requirement for the company to legally attempt its fifth high-altitude Starship launch and landing. While FAA approval is the latest of several promising signs that SpaceX may able to be squeeze in a Starship launch attempt before the weekend, some ambiguity still remains.

As of April 29th, Starship SN15’s launch debut now has an active FAA license, a Temporary Flight Restriction (TFR) to clear airspace, a marine hazard notice to warn maritime operators, and a highway closure all set for Friday, April 30th. The upgraded Starship prototype has also completed two back-to-back Raptor static fires without any apparent issues and without a need to replace one or more of those engines – a first for a multi-engine Starship prototype.

On the other hand, SpaceX has yet to officially confirm plans for a Friday launch attempt on social media or SpaceX.com and the company has yet to distribute evacuation notices to the few residents that still live in Boca Chica Village. Additionally, weather conditions are likely to be poor on Friday and Starship SN15 still hasn’t been outfitted with explosive Flight Termination System (FTS) charges – a step that’s generally been performed 24+ hours before prior Starship launch attempts.

Update: SpaceX began installing Starship SN15’s FTS charges around 11pm CDT on April 29th.

Knowing SpaceX, it’s more likely than not that the company is capable of installing FTS less than 24 hours before a launch attempt, but it’s still a departure from the norm and thus noteworthy. Oddly, SpaceX has once again filed TFRs for apparent launch windows on Saturday and Sunday, though the company hasn’t so much as attempted a basic Starship tanking test on a weekend since well before high-altitude flight tests began five months ago.

As such, if SpaceX is unable to launch Starship SN15 tomorrow, it’s far likelier that the next window will open on Monday, May 3rd. Weather forecasts currently show a ~50% chance of thunderstorms and low visibility on Friday and Saturday, with conditions clearing up for a mostly sunny outlook from Sunday through Tuesday. Stay tuned for updates as SpaceX continues to prepare for what could be the first fully successful high-altitude Starship launch and landing.

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:

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:

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’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 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.
