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 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.

Elon Musk told The Economist that artificial intelligence will likely surpass the combined intelligence of every human on Earth within about five years, and that humans may not remain in charge once that happens. In a wide-ranging interview with editor-in-chief Zanny Minton Beddoes, recorded at Giga Texas for the outlet’s Insider series, Musk compared the widening gap between AI and human intelligence to the gap between humans and chimpanzees.
“It’s hard to imagine that the chimpanzee would be in charge,” he said, addressing what happens to human authority once AI moves far beyond us.
Elon Musk reiterates his most optimistic prediction yet with “UHI” forecast
Musk’s timeline stretches out from there. Five years for AI to out-think humanity combined, ten years before humans lose meaningful control, and by 2036, he says, money itself may stop mattering.
Musk notes that if robots and AI produce more goods and services than people could ever consume, currency loses its purpose. He told Beddoes that governments could respond with direct payments, what he called “universal high income,” a term he first used in an X post last August describing a future where “everyone will have the best medical care, food, home, transport and everything else.”
There will be universal high income (not merely basic income).
Everyone will have the best medical care, food, home, transport and everything else.
Sustainable abundance.

He also floated a more surprising prediction that deflation, and not inflation, would become the bigger economic problem, since expanding the supply of goods and services faster than the money supply grows would push prices down rather than up.
None of this is new territory for Musk, who has spent years describing an “age of abundance” built on Optimus and autonomous vehicles. What’s notable is the timing. The interview landed the same week Tesla shares dropped roughly 19 percent following a second quarter earnings report that beat on revenue but missed badly on profit, and as SpaceX stock continues to slide from its post-IPO peak.
Musk’s own net worth has fallen close to $700 billion since mid-June, according to the Bloomberg Billionaires Index, even as he describes a future where personal wealth stops being the point.
Musk did not dodge the risk side of the equation either. He put the odds of AI contributing to human extinction somewhere in the 10 to 20 percent range, then arrived at what he called his “philosophical conclusion” since the technology cannot realistically be stopped and the arguably better response is to keep building it and hope the outcome leans toward abundance rather than catastrophe. “I’ve gone from exhilaration to terror regarding AI,” he told Beddoes, “even intraday.”
Tesla is adding a new “Traction Control Modes” feature to its cars for better handling in any conditions. These features will roll out to the Model 3 and Model Y, the two vehicles in Tesla’s lineup that typically do not have drive modes for various conditions.
Tesla did include this in the Model S and Model X, as well as the Cybertruck.
The new feature will roll out with the 2026 Summer Update, which Tesla announced last week and subsequently started rolling out to some owners today. The Summer Update is the latest iteration of the usual four seasonal releases the company rolls out throughout the year. These releases typically feature some owner-requested features, as well as improvements to things like the Full Self-Driving suite.
Tesla reveals 2026 Summer Update with crazy fixes to Nav and more
This release is no different. Among the changes are improvements to Navigation, new customization options with wraps and how they can be shared and stored, more functionality with the Tesla smartphone app, and new gamification with self-driving.
However, Tesla announced today that it was adding another feature to the Summer Update. Traction Control Modes will now be available with the release
Tesla describes them:
-
“Choose from three updated Traction Control Modes: Auto for normal driving conditions, Slippery Surface for icy or wet roads, Stuck Assist when stuck in snow, mud, or sand. The mode resets to Auto at the start of each drive. To select, go to Controls > Dynamics > Traction Control Mode.”
Tesla’s 2026 Summer Update also includes new Traction Control Modes

— TESLARATI (@Teslarati) July 26, 2026
The use of these modes will help improve a Tesla’s overall performance in less-than-ideal conditions. Typically, these traction control modes monitor wheel speed through sensors and track engine power to adjust responsiveness in various conditions.
These drive modes are not an ultimate solution to all driving conditions; just because there is a “Stuck Assist,” doesn’t mean your Tesla will dig itself out of a foot-and-a-half trench during a blizzard. It is important to remember that some of these scenarios also require some assistance from the driver. For example, driving in sand requires tires to be aired down significantly to increase traction and control.
However, this will be a welcome addition for those who use the Full Self-Driving suite and might not be convinced of its performance in adverse conditions. Some of us prefer to be in control in rain, snow, or ice, which is totally understandable. However, adjusting the Traction Control Mode while utilizing FSD in snow, rain, or ice could increase confidence and overall experience.

Tesla’s Summer Update is already rolling out to some owners, so it should be making its way to most of the fleet over the next several weeks. The Spring Update rolled out at a very conservative pace, so if you don’t have it by the end of August, don’t be too upset. It might just be Tesla’s method.
Just hours after Starship Flight 13 achieved a successful soft splashdown of its upper stage in the Indian Ocean on July 24, Elon Musk announced an ambitious next step for the company’s next launch of the rocket.
“Unless we discover problems after mission data review, SpaceX will attempt to catch the ship with the tower on [the] next flight,” the SpaceX CEO posted on X on Friday.
That “next flight” is expected to be Flight 14. The plan involves returning the Starship upper stage, commonly called the “ship,” to the Starbase launch tower in Texas and catching it mid-air using the same mechanical “chopsticks” arms that have already proven themselves with the Super Heavy booster.

— Elon Musk (@elonmusk) July 25, 2026
A successful catch would mark the first time an orbital-class upper stage has been recovered this way, advancing SpaceX’s goal of full and rapid reusability for the entire vehicle.
SpaceX has already demonstrated the tower-catch technique multiple times with Super Heavy. The first successful catch came on Flight 5 in October 2024, when Booster 12 was plucked from the sky by the Mechazilla arms. Subsequent flights, including those involving Boosters 14 and 15, repeated the feat. Several of those recovered boosters were later inspected, refurbished, and flown again, proving the system’s viability for quick turnaround.

Traditional reusable rockets, such as SpaceX’s own Falcon 9 or Blue Origin’s New Shepard, land on legs either on land or droneships. Rocket Lab has recovered its small Electron first stages by helicopter, but those are far lighter vehicles.
SpaceX Starship just nailed something it’s never done before
The China Academy of Launch Vehicle Technology (CALT), a subsidiary of the China Aerospace Science and Technology Corp. (CASC), completed a catch of its booster on July 10. They are the only entity besides SpaceX to attempt and complete the feat.
Flight 13 provided encouraging data. The ship executed a controlled reentry, flipped, and soft-landed intact in the ocean after deploying Starlink satellites, offering the first clear post-splashdown views of an undamaged heat shield. The Super Heavy booster, meanwhile, experienced a harder splashdown in the Gulf of Mexico.
Musk has previously stressed that ship catches would only follow multiple successful soft ocean landings to minimize risk of debris over land.
If Flight 14 succeeds, SpaceX would take a major stride toward routine, rapid reuse of both stages—critical for lowering launch costs and supporting ambitious plans for lunar and Mars missions. For now, teams are reviewing the Flight 13 data. Should everything check out, the next Starship flight could deliver one of the most spectacular recoveries in aerospace history.
