SpaceX ‘destacks’ Starship and Super Heavy: what’s next?

Published

on

On February 14th, a bit less than four days after the giant rocket was used as a backdrop for CEO Elon Musk’s first Starship presentation in years, SpaceX lifted Starship off of the Super Heavy booster and lowered the upper stage to the ground.

In early August 2021, the same pair – Booster 4 and Ship 20 – were stacked for the first time for what was described as a fit test. After briefly forming the largest rocket ever assembled, the stages were ‘destacked’ about an hour later and would ultimately return to the Starbase factory for finishing touches. Six months, one ship cryoproof, three booster cryoproofs, and three ship static fire tests later, Ship 20 and Booster 4 were once stacked to form a massive 119-meter-tall (390 ft) tall rocket

This time around, Starship S20 was stacked on top of Super Heavy B4 not with a giant crane but with a ‘launch and integration tower’ that had been outfitted with three giant arms in the interim. The tower’s main pair of arms – ‘chopsticks’ – lifted the ~100-ton (~220,000 lb) Starship almost 100 meters off the ground, swung it over Super Heavy, and then carefully lowered the stages until Super Heavy was able to latch on.

On its first true demonstration, the complex process went far smoother than anyone outside of SpaceX expected, taking the tower just four or so hours from the start of the lift to hard mate. On February 10th, shortly before Musk’s Starship update, SpaceX even opened the ‘chopsticks’ to their full breadth, leaving all of Starship S20’s weight on Super Heavy B4 and also demonstrating what the pad will likely look like moments before the first orbital Starship launch.

On February 14th, after about four days fully stacked, the tower arms reattached to Ship 20, detached from Super Heavy, and lowered the Starship back to the ground, where it was eventually installed on a transport stand. Later that night and early the next day, SpaceX then moved the ship to a small concrete pad adjacent to the launch tower that’s believed to be meant for cryogenic proof testing. It’s unclear why SpaceX didn’t tested the fully stacked Starship given that both ship and booster have already completed multiple cryogenic proof tests (or wet dress rehearsals with real propellant) over the last few months.

It’s also unclear what more SpaceX can gain from testing Ship 20 on the ground, short of full-stack operations. On Sunday, February 13th, SpaceX did, however, begin filling the orbital launch site’s fuel tanks with liquid methane (LCH4) for the first time. It’s possible that instead of using Ship 20 to test any aspect of the relatively ancient Starship prototype, SpaceX will use Ship 20 to test the orbital tank farm – particularly the fuel side of the farm, which has yet to be tested. Perhaps after testing those systems on the ground, SpaceX will re-stack Ship 20 and Booster 4 and perform a similar wet dress rehearsal to test the tower’s plumbing, the ship-fueling arm, and the overall structural integrity of the fully-stacked rocket.

SpaceX has test windows tentatively scheduled on February 16th, 17th, and 18th.

Tesla sues former Optimus engineer for stealing trade secrets

Tesla is suing former Optimus engineer Jay Li in federal court after accusing him of stealing trade secrets and using them to enable a startup he founded after he left.

Li is accused of stealing confidential files and using them to help get his company, “Proception,” off to a rocking start. Tesla says the files Li took helped his new startup “shortcut the typical development process” for robot hands, something that took Tesla years to develop and evolve.

The company said in the complaint (via Reuters):

“Through Li’s pilfering, Defendant Proception purportedly achieved in a matter of months what it has taken Tesla over four years, hundreds of employees, and billions of dollars to achieve.”

Li was an employee at Tesla for several years, working on the Optimus sensor team from 2022 to 2024. The company says it utilized and devoted “extraordinary resources” to the development of Optimus, which has come a long way since its unveiling several years ago.

Li allegedly downloaded confidential files related to Optimus’ robotic hand movement research before departing the company. He did not work on the hands at the time. However, he left and swiftly started Proception, as the suit states the company was founded just six days after he left Tesla.

Proception was gloating about its ability to build robotic hands just five months after the company was founded. Tesla says the hands have “striking similarities” to its own design for Optimus.

The company is looking for monetary damages and a court order that would block Proception from misusing the secrets it accuses Li of taking.

This is not the first suit Tesla has filed over trade secrets and confidential information theft. Recently, it accused German-Canadian dual citizen Klaus Pflugbeil of stealing battery-related secrets. He was arrested and sentenced to two years in prison.

Tesla teases new Model Y seating option potentially coming soon

Tesla appears to be ready to launch the new Model Y seating option in the coming weeks.

Tesla teased a new Model Y seating option earlier this week in a promotional email, potentially hinting that it could introduce an arrangement offered on the legacy version of the vehicle.

Back in 2021, Tesla started offering a seven-seat configuration of the Model Y, and there was a lot of speculation about its orientation and the space it would provide. The two additional seats were truly a tight fit for anyone, even kids, as the space for a third row was extremely limited in the Model Y.

Eventually, Tesla started building the seven-seater with forward-facing seats and very tight legroom dimensions. It was beneficial for some, but many still considered the arrangement to be too confined for their needs.

The company confirmed earlier this year in an interview with Jay Leno that the car would get other configurations, including Rear-Wheel-Drive, which has already launched, a Performance trim, which has been spotted with bumper covers several times this year, and a seven-seat version:

The new seven-seater could be coming soon as well, according to a recent email Tesla sent to customers and fans. In it, Tesla writes:

“Ready for anything with long range seating for up to seven and enough room for everyone’s gear.”

Tesla did have a mysterious Model Y roaming around the Fremont Factory’s test track recently with covered bumpers and what appeared to be strange dimensions.

We thought it might be the compact, affordable model that is set to launch in the first half of the year, but now it seems that the car could have either been the Model Y seven-seater or the Model Y Performance configuration, as they are both expected soon.

We are interested to see if Tesla can squeak out a few more inches of legroom in the new seven-seater, but we’re not holding our breath. Nevertheless, the new Model Y came with quite a few improvements, including suspension changes, acoustic-lined glass for a better cabin experience, and a front and rear bumper redesign, among other things.

There is no doubt it will be a better car than the legacy version.

Tesla Full Self-Driving’s European launch frustrations revealed by Elon Musk

Tesla plans to launch Full Self-Driving in Europe later this year, but regulatory bodies are proving to make it a bigger challenge than it needs to be.

Tesla Full Self-Driving is set to launch in Europe in the future, but the region’s governing bodies are not giving the suite any chance to move forward, according to CEO Elon Musk, who blames the regulatory processes for robbing citizens of a safer mode of travel.

The automaker revealed late last year that it planned to bring Full Self-Driving to Europe sometime in 2025. However, Musk said that the launch of the suite is being continuously prolonged by both individual and European Union officials, dragging their feet with approvals.

In a post on X on Wednesday, Musk said the company is still dealing with and waiting for approvals from both the Dutch government and the EU’s governing officials, giving an indication that some progress has been made, but ultimately, there are still some bodies that are taking their time:

He continued by stating that the delays are “very frustrating” and they “hurt the safety of people in Europe” because of Autopilot’s statistical prowess, which shows it is much safer than human drivers.

Tesla is readying for the launch of a completely driverless Robotaxi platform in the U.S., which is set to occur in the coming days. While the initial rollout of the platform will be reserved for a select few, public rides are slated for June 22, meaning anyone will be able to come to Austin and hail a Tesla Robotaxi through the company’s smartphone app.

The first Robotaxi without a driver was spotted in Austin yesterday and shared on X:

Musk dropped several hints that the Robotaxi launch, which has been rumored for June 12, is imminent. For now, the operation will take place in Austin and will eventually expand, likely to California next, as noted in past reports. The City’s official website confirmed that Tesla gained a license as an Autonomous Vehicle operator in the City of Austin earlier this week.

Tesla applied for a similar license in California earlier this year.
