SpaceX CEO Elon Musk says that there is a “slight error” with the current design of Starship’s forward flaps, necessitating a few small but visible changes on future prototypes of the spacecraft.

Measuring 9m (30 ft) wide and approximately 50m (~165 ft) from tip to tail, Starship is the combined upper stage, spacecraft, tanker, and lander of a two-stage, fully-reusable rocket with the same name. While SpaceX has a long ways to go to achieve it, the company’s ambition is for Starship and its Super Heavy booster to be the most easily and quickly reusable spacecraft and rocket booster ever built, nominally enabling the same-day reuse of both.

Beyond a Space Shuttle-style heat shield of blankets and ceramic tiles, the Starship upper stage is meant to achieve that reusability by descending through the atmosphere and landing unlike any other spacecraft, plane, or rocket ever flown. Instead of flying, gliding, or knifing through the atmosphere nose or tail-first, Starship freefalls perpendicular to the ground for the last few dozen kilometers (~10-20 mi) before aggressively flipping into a vertical orientation at the last second and landing propulsively on its tail. Now, according to Elon Musk, two of the four ‘flaps’ that largely make that exotic maneuver possible are set for a small but significant redesign.

Over the course of five suborbital test flights of full-scale Starship prototypes completed between December 2020 and May 2021, SpaceX took that exotic landing concept from the drawing board and subscale wind tunnel testing to reality. Though four of those five tests ended in destruction, their respective Starship prototypes really only failed in the last 15-30 seconds of test flights that were more than six minutes long.

After reaching an apogee of 10-12.5 km (~6.2-7.8 mi) over the course of some four and a half minutes, all five Starship prototypes successfully shut down their Raptor engines, tipped over onto their bellies, and then used a combination of small pressurized gas thrusters and four large flaps to stably fall back to Earth. Much like a skydiver can tweak their body, arms, and legs to control their orientation and attitude, Starship uses two pairs of forward and aft flaps to achieve a very similar level of control.

Thanks to Starship’s significant surface area and relatively low mass shortly before landing, that unprecedented freefall-style descent naturally slows the rocket to just 100-200 mph (~50-100 m/s) while simultaneously allowing SpaceX to avoid the massive complexity and added mass of structural wings or fins like those on the Space Shuttle. Further, whereas the Shuttle used its wings to glide (albeit like a brick) and land on very long runways, Starship is designed to use three of its six Raptor engines to flip into a vertical orientation and land much like SpaceX’s own spectacularly successful Falcon boosters.

During the actual process of reentry, in which Starship uses a heat shield made up of ~15,000 ceramic tiles to slow from orbital (Mach 25 or ~7.5 km/s) to subsonic speeds, those same flaps also come in useful to control the vehicle’s angle of attack and thus the degree of extreme heating experienced. According to Musk, to improve the moment arm (i.e. leverage or, all else equal, torque) of Starship’s forward flaps and reduce or remove undesirable aerodynamic characteristics, SpaceX is going to shrink those forward flaps further, move them closer together and more towards the tip of Starship’s nose, and angle them toward the ship’s leeward side (back).

Apparently, those relatively minor changes mean that a portion of Starship’s forward flaps will no longer be directly subjected to reentry heating, potentially allowing SpaceX to entirely remove static “aerocovers” that wrap around the ship’s flaps to prevent superheated plasma and gas from reaching sensitive components. Ironically, SpaceX’s thermal protection team completed the installation of heat shield tiles on one of those forward flap aerocovers for the first time ever just a few days ago – a structure and portion of heat shield that will apparently no longer be needed on future Starships.

For now, though, it looks like Ship 20 will attempt Starship’s first orbital launch with its now-outdated forward flaps. Depending on how far along Ship 21 production is, the next prototype could feasibly sport that new flap design.

Tesla CEO Elon Musk’s $1 trillion pay package hits first adversity from proxy firm

ISS said the size of the pay package will enable Musk to have access to “extraordinarily high pay opportunities over the next ten years,” and it will have an impact on future packages because it will “reduce the board’s ability to meaningfully adjust future pay levels.”

Tesla CEO Elon Musk’s $1 trillion pay package, which was proposed by the company last month, has hit its first bit of adversity from proxy advisory firm Institutional Shareholder Services (ISS).

Musk has called the firm “ISIS,” a play on its name relating it to the terrorist organization, in the past.

The pay package aims to lock in Musk to the CEO role at Tesla for the next decade, as it will only be paid in full if he is able to unlock each tranche based on company growth, which will reward shareholders.

However, the sum is incredibly large and would give Musk the ability to become the first trillionaire in history, based on his holdings. This is precisely why ISS is advising shareholders to vote against the pay plan.

The group said that Musk’s pay package will lock him in, which is the goal of the Board, and it is especially important to do this because of his “track record and vision.”

However, it also said the size of the pay package will enable Musk to have access to “extraordinarily high pay opportunities over the next ten years,” and it will have an impact on future packages because it will “reduce the board’s ability to meaningfully adjust future pay levels.”

The release from ISS called the size of Musk’s pay package “astronomical” and said its design could continue to pay the CEO massive amounts of money for even partially achieving the goals. This could end up in potential dilution for existing investors.

If Musk were to reach all of the tranches, Tesla’s market cap could reach up to $8.5 trillion, which would make it the most valuable company in the world.

Tesla has made its own attempts to woo shareholders into voting for the pay package, which it feels is crucial not only for retaining Musk but also for continuing to create value for shareholders.

Musk has also said he would like to have more ownership control of Tesla, so he would not have as much of an issue with who he calls “activist shareholders.”

Tesla is adding an interesting feature to its center touchscreen in a coming update, according to a noted hacker.

In a recent dissection of coding, Tesla hacker green noticed that the company is bringing in screenshare with Software Update 2025.38. Details on the use case are slim, but he said the feature would export the car screen so it could be viewed remotely.

It would bring up a notification on the screen, along with a four-digit pin that would link the two together:

As previously mentioned, the use case is unclear, but there are some ideas. One of which is for remote support, which is something Apple has used to help resolve issues with its products.

Support staff and employees routinely tap into customers’ screens to help resolve issues, so this could be a way Tesla could also use it.

This seems especially relevant with Robotaxi, as the screen might be a crucial part of resolving customer complaints when there is no employee in the car.

Additionally, it seems as if it will not be exclusive to those owners who have newer vehicles that utilize the AMD chip. Intel will get support with the new feature as well, according to what green has noticed in the coding.

Finally, it could also be used with all sorts of content creation, especially as Full Self-Driving videos and what the vehicle sees in Driver Visualization.

As it is released, Tesla will likely release more information regarding what the screensharing mode will be used for.

For right now, many owners are wondering where it could actually work and what advantages it will offer for owners as well as the company itself.

SpaceX posts Starship booster feat that’s so nutty, it doesn’t even look real

The Super Heavy booster’s feat was so impressive that the whole maneuver almost looked like it was AI-generated.

SpaceX has shared a video of a remarkable feat achieved by Starship’s Super Heavy booster during its 11th flight test.

The Super Heavy booster’s feat was so impressive that the whole maneuver, which was captured on video, almost looked like it was AI-generated.

Super Heavy’s picture perfect hover

As could be seen in the video shared by SpaceX, Starship’s Super Heavy booster, which is nearly 400 feet tall, smoothly returned to Earth and hovered above the Gulf of America for a few seconds before it went for its soft water landing. The booster’s picture-perfect maneuver before splashing down all but capped a near-flawless mission for Starship, which is about to enter its V3 era with Flight 12.

The booster’s balance and stability were so perfect that some users on X joked that the whole thing looked AI-generated. Considering the size of Super Heavy, as well as the fact that the booster was returning from space, the hovering display all but showed that SpaceX is dead serious about keeping its dominant lead in the spaceflight sector.

Starship V2’s curtain call

As noted in a Space.com report, Flight Test 11 achieved every major goal SpaceX had set for the mission, including deploying Starlink mass simulators, relighting Raptor engines in space, and executing a stable reentry for both the Starship Upper Stage and the Super Heavy booster. The feat also marked the second time a Super Heavy booster has been reflown, a milestone in SpaceX’s quest to make the entire Starship system fully reusable.

Starship’s V2 vehicle will now give way to the upgraded Starship V3, which is designed for faster turnaround and higher payload capacity. The Starship program is expected to pursue even more aggressive targets in the coming months as well, with Elon Musk stating on social media platform X that SpaceX will attempt a tower catch for Starship Upper Stage as early as spring 2026.
