SpaceX has successfully completed a Falcon 9 static fire ahead of Starlink’s first dedicated launch, breaking a practice that dates back to Falcon 9’s last catastrophic failure to date.

That failure occurred in September 2016 around nine minutes before a planned Falcon 9 static fire test, completely destroying the rocket and the Amos-6 communications satellite payload and severely damaging Launch Complex 40 (LC-40). Since that fateful failure, all 42 subsequent Falcon 9 and Falcon Heavy satellite launches have been preceded by static fire tests without a payload fairing attached. This process typically adds 24-48 hours of work to launch operations, an admittedly tiny price to pay to reduce the chances of a rocket failure completely destroying valuable payloads. With Starlink v0.9, SpaceX is making different choices.

When supercool liquid oxygen ruptured a composite overwrapped pressure vessel (COPV) in Falcon 9’s upper stage, the resultant explosion and fire destroyed Falcon 9. Perhaps more importantly, the ~$200M Amos-6 satellite installed atop the rocket effectively ceased to exist, a loss that posed a serious threat to the livelihood of its owner, Spacecom. Posed with a question of whether saving a day or two of schedule was worth the potential destruction of customer payloads, both customers, SpaceX, and their insurers obviously concluded that static fires should be done without payloads aboard the rocket.

The only exceptions since Amos-6 are the launch debuts of Falcon Heavy – with a payload that was effectively disposable and SpaceX-built – and Crew Dragon DM-1, in which Falcon 9’s integration with Dragon’s launch abort system had to be tested as part of the static fire. Every other SpaceX rocket launch since September 2016 has excluded payloads during each routine pre-flight static fire.

SpaceX’s Spacecraft Emporium

Why the change of pace on this launch, then? The answer is simple: for the first time ever, SpaceX is both the sole payload/satellite stakeholder and launch provider, meaning that nearly all of the mission’s risk – and the consequences of failure – rest solely on SpaceX’s shoulders. In other words, SpaceX built and owns the Falcon 9 assigned to the mission, the 60 Starlink test satellites that make up its payload, and the launch complex supporting the mission.

Even then, if Falcon 9 were to fail during an internal SpaceX mission, customer launches could be seriously delayed by both the subsequent failure investigation failure and any potential damage to the launch complex. In short, although an internal mission does offer SpaceX some unique freedoms, it is still in the company’s best interest to treat the launch like any other, even if some customer-oriented corners are likely begging to be cut. Additionally, the loss of SpaceX’s first dedicated payload of 60 Starlink satellites could be a significant setback for the constellation, although it may be less significant than most would assume.

This is not to say that SpaceX won’t take advantage of some of the newfound freedom permitted by Starlink launches. In fact, CEO Elon Musk has stated that one of SpaceX’s 2019 Starlink missions will become the first to reuse a Falcon fairing. Additionally, SpaceX is free to do things that customers might be opposed to but that the company’s own engineers believe to be low-risk. Notably, Starlink missions will be an almost perfect opportunity for SpaceX to flight-prove reusability milestones without having to ask customers to tread outside of their comfort zones.

The sheer scale of SpaceX proposed Starlink constellation – two phases of ~4400 and ~12,000 satellites – means that the company will need all the latent launch capacity it can get over the next 5-10 years, at least until Starship/Super Heavy is able to support internal missions. Extraordinary packing density will help to minimize the number of launches needed, but the fact remains that even an absurd 120 satellites per launch (double Starlink v0.9’s 60) would still require an average of 12 launches per year to finish Starlink before 2030.

In the meantime, thoughts of a dozen or more annual Starlink launches are somewhat premature. SpaceX’s first dedicated Starlink launch (deemed Starlink v0.9) is scheduled to lift off no earlier than 10:30 pm EDT (02:30 UTC), May 15th, and is being treated as an advanced but still intermediary step between the Tintin prototypes and a finalized spacecraft design. Still, in an unprecedented step, SpaceX has built sixty Starlink satellites for the development-focused mission, in stark contrast to the six satellites (still a respectable achievement) competitor OneWeb launched in February 2019 as part of its own flight-test program.

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.
