SpaceX Starship Integrated Flight Test 2: What to Expect
After a one-day delay to replace a failed grid fin actuator, SpaceX is now less than 24 hours from the second test flight of Starship. SpaceX will have a 20-minute launch window that opens at 7:00 AM CT (13:00 UTC).
Making this test flight is Ship 25 and Booster 9. Ship 25 is powered by 6 Raptor engines (3 sea level and 3 vacuum), and Booster 9 is powered by 33 Raptor engines.
Booster 9 features many upgrades over the last booster to take flight, including better engine shielding and a switch from hydraulic thrust vector controls to electric TVC. Ship 25 didn’t see as many upgrades as the booster, and not much has been shared of any major changes that were made. One change to both vehicles was the improvement of the Flight Termination System, which took much longer to destroy the rocket than expected during the first test.
Launch Day
T minus 2 hours before the scheduled liftoff, the SpaceX launch director will give the go for propellant loading. This process will begin at t minus 1 hour and 37 minutes, and at this point, Booster 9 will begin loading with both liquid oxygen and liquid methane.
T minus 1 hour and 17 minutes, liquid methane will begin loading onto Ship 25, followed by liquid oxygen 4 minutes later at t minus 1 hour and 13 minutes.
T minus 19 minutes and 40 seconds, the 39 Raptor engines on Booster 9 and Ship 25 will begin chilling to prepare for the extremely cold fuel to flow through and prevent thermal shock to engine hardware.
T minus 10 seconds, the flame deflector installed after the first IFT will begin flowing water.

T minus 3 seconds, Raptor engine ignition begins, and thrust begins to build to allow for liftoff.
LIFT OFF!
T+ 2 seconds, the 2nd Integrated Flight Test should now be officially underway, with Booster 9 thundering away from the orbital launch mount.

T+ 52 seconds, Starship and Booster 9 reach Max Q, the area of maximum dynamic pressure on the vehicle will occur here. If (or most) all Raptor engines on Booster 9 are performing nominally, the vehicle will pass through this fairly quickly.
T+ 2 minutes and 39 seconds, Staging. This will be the first time SpaceX has ever attempted hot staging. Almost all of Booster 9 engines will cut out, and Ship 25 will ignite its Raptor engines to separate from the booster. This is all unknown territory from this point on for SpaceX, as the first test flight did not make it this far. SpaceX has yet to clarify how many Ship 25 engines will ignite during this process.
If all goes well, Booster 9 will begin its flip and boost backburn at t+ 2 minutes and 53 seconds, which will last ~54 seconds. Unlike the Falcon 9, the booster is not designed to perform an entry burn.
T+ 6 minutes and 30 seconds after lift-off, Booster 9 will begin its landing burn for a hopeful soft touchdown in the Gulf of Mexico 18 seconds after landing burn ignition. The planned landing area is ~20 miles (32 km) downrange.
Meanwhile, Ship 25 will continue burning its 6 Raptor engines until t+ 8 minutes and 33 seconds, inserted into a sub-orbital trajectory, and then enter a coast phase until its planned reentry North of the Hawaiian islands.
Landing!
At t+ 1 hour and 17 minutes, Starship will begin feeling the effects of the atmosphere, its first real test for the heatshield. If it survives atmospheric entry, Starship will splash down in the Pacific Ocean at t+ 1 hour and 30 minutes after lift off. SpaceX has said Ship 25 will not attempt a landing burn during this test.
If Starship is able to make it past staging, SpaceX will most likely consider this test a success, but it would be a major accomplishment for Ship 25 to survive entry back through the atmosphere and gather important data for the company.
If you have a chance to make it to South Texas or even the other side of the Rio Grande in Mexico, it’ll be a sight you’ll never forget. If you’re watching from home, SpaceX will begin streaming the launch on X and their website 35 minutes before lift-off.

Tesla FSD’s newest model is coming, and it sounds like ‘the last big piece of the puzzle’
“There’s a model that’s an order of magnitude larger that will be deployed in January or February 2026.”
Tesla Full Self-Driving’s newest model is coming very soon, and from what it sounds like, it could be “the last big piece of the puzzle,” as CEO Elon Musk said in late November.
During the xAI Hackathon on Tuesday, Musk was available for a Q&A session, where he revealed some details about Robotaxi and Tesla’s plans for removing Robotaxi Safety Monitors, and some information on a future FSD model.
While he said Full Self-Driving’s unsupervised capability is “pretty much solved,” and confirmed it will remove Safety Monitors in the next three weeks, questions about the company’s ability to give this FSD version to current owners came to mind.
Musk said a new FSD model is coming in about a month or two that will be an order-of-magnitude larger and will include more reasoning and reinforcement learning.
He said:
“There’s a model that’s an order of magnitude larger that will be deployed in January or February 2026. We’re gonna add a lot of reasoning and RL (reinforcement learning). To get to serious scale, Tesla will probably need to build a giant chip fab. To have a few hundred gigawatts of AI chips per year, I don’t see that capability coming online fast enough, so we will probably have to build a fab.”
NEWS: Elon Musk says FSD Unsupervised is “pretty much solved at this point” and that @Tesla will be launching Robotaxis with no safety monitors in about 3 weeks in Austin, Texas. He also teased a new FSD model is coming in about 1-2 months.

It rings back to late November when Musk said that v14.3 “is where the last big piece of the puzzle finally lands.”
With the advancements made through Full Self-Driving v14 and v14.2, there seems to be a greater confidence in solving self-driving completely. Musk has also personally said that driver monitoring has been more relaxed, and looking at your phone won’t prompt as many alerts in the latest v14.2.1.
This is another indication that Tesla is getting closer to allowing people to take their eyes off the road completely.
Along with the Robotaxi program’s success, there is evidence that Tesla could be close to solving FSD. However, it is not perfect. We’ve had our own complaints with FSD, and although we feel it is the best ADAS on the market, it is not, in its current form, able to perform everything needed on roads.
But it is close.
That’s why there is some legitimate belief that Tesla could be releasing a version capable of no supervision in the coming months.
All we can say is, we’ll see.

SpaceX IPO is coming, CEO Elon Musk confirms
However, it appears Musk is ready for SpaceX to go public, as Ars Technica Senior Space Editor Eric Berger wrote an op-ed that indicated he thought SpaceX would go public soon. Musk replied, basically confirming it.
Elon Musk confirmed through a post on X that a SpaceX initial public offering (IPO) is on the way after hinting at it several times earlier this year.
It also comes one day after Bloomberg reported that SpaceX was aiming for a valuation of $1.5 trillion, adding that it wanted to raise $30 billion.
Musk has been transparent for most of the year that he wanted to try to figure out a way to get Tesla shareholders to invest in SpaceX, giving them access to the stock.
He has also recognized the issues of having a public stock, like litigation exposure, quarterly reporting pressures, and other inconveniences.

As usual, Eric is accurate

Berger believes the IPO would help support the need for $30 billion or more in capital needed to fund AI integration projects, such as space-based data centers and lunar satellite factories. Musk confirmed recently that SpaceX “will be doing” data centers in orbit.
AI appears to be a “key part” of SpaceX getting to Musk, Berger also wrote. When writing about whether or not Optimus is a viable project and product for the company, he says that none of that matters. Musk thinks it is, and that’s all that matters.
It seems like Musk has certainly mulled something this big for a very long time, and the idea of taking SpaceX public is not just likely; it is necessary for the company to get to Mars.
The details of when SpaceX will finally hit that public status are not known. Many of the reports that came out over the past few days indicate it would happen in 2026, so sooner rather than later.
But there are a lot of things on Musk’s plate early next year, especially with Cybercab production, the potential launch of Unsupervised Full Self-Driving, and the Roadster unveiling, all planned for Q1.
Tesla has added the 15th automaker to the growing list of companies whose EVs can utilize the Supercharger Network this year, as BMW is the latest company to gain access to the largest charging infrastructure in the world.
BMW became the 15th company in 2025 to gain Tesla Supercharger access, after the company confirmed to its EV owners that they could use any of the more than 25,000 Supercharging stalls in North America.
Welcome @BMW owners.

Newer BMW all-electric cars, like the i4, i5, i7, and iX, are able to utilize Tesla’s V3 and V4 Superchargers. These are the exact model years, via the BMW Blog:
- i4: 2022-2026 model years
- i5: 2024-2025 model years
- 2026 i5 (eDrive40 and xDrive40) after software update in Spring 2026
- i7: 2023-2026 model years
- iX: 2022-2025 model years
- 2026 iX (all versions) after software update in Spring 2026
With the expansion of the companies that gained access in 2025 to the Tesla Supercharger Network, a vast majority of non-Tesla EVs are able to use the charging stalls to gain range in their cars.
So far in 2025, Tesla has enabled Supercharger access to:
- Audi
- BMW
- Genesis
- Honda
- Hyundai
- Jaguar Land Rover
- Kia
- Lucid
- Mercedes-Benz
- Nissan
- Polestar
- Subaru
- Toyota
- Volkswagen
- Volvo
Drivers with BMW EVs who wish to charge at Tesla Superchargers must use an NACS-to-CCS1 adapter. In Q2 2026, BMW plans to release its official adapter, but there are third-party options available in the meantime.
They will also have to use the Tesla App to enable Supercharging access to determine rates and availability. It is a relatively seamless process.
