SpaceX has set the stage for a record-breaking Starship booster static fire after the rocket completed a complex fueling test and launch rehearsal earlier this week.

On January 25th, a tower the size of a skyscraper activated a pair of giant mechanical arms to disassemble the largest rocket ever built. The arms carefully grabbed Starship using hard points under its flaps and lifted the 50-meter-tall second stage and spacecraft off of Super Heavy Booster 7. Nicknamed Mechazilla, the robot lowered the hundred-ton (~220,000+ lbs) vehicle hundreds of feet onto a waiting stand and eventually let go. On January 26th, SpaceX transported Ship 24 back to its Starbase, Texas factory for finishing touches.

Booster 7 remained installed on Starbase’s donut-shaped orbital launch mount, which uses clamps and umbilicals to hold Starship in place and power, fuel, and pressurize Super Heavy. In theory, the next time Booster 7 leaves that launch mount, it will do so under its own power. But first, SpaceX must ensure that that unprecedented power can be controlled (and survived).

This, unfortunately, is far from the first iteration of this story. SpaceX has been seemingly close to the milestone at many points over the last year and a half. In September 2021, for example, CEO Elon Musk reported that Super Heavy Booster 4 would attempt the first static fire on Starbase’s orbital launch mount later that month. Eleven months later, Super Heavy Booster 7 gave the OLM its inaugural static fire test – albeit with just one of its 33 engines.

In the months following that static fire, Booster 7 completed another single-engine test, a two-engine test, a seven-engine test, a fourteen-engine test, and a long-duration eleven-engine test. All of that slow and steady testing has been fairly successful and caused no major damage to the rocket or pad. But five months after it began, SpaceX has never ignited more than 14 – 42% – of Super Heavy’s 33 Raptor engines at once. That must change before SpaceX can gain enough confidence in Starship for (and convince the FAA to license) an orbital launch attempt.

During Super Heavy B7’s 14-engine static fire, the booster could have produced up to 3220 tons (7.1 million pounds) of thrust. When it ignites all 33 available engines for the first time, its maximum thrust could leap to 7590 tons (16.7 million pounds), beating the next most powerful rocket in history – the Soviet N1 – by nearly 60%. In other words, SpaceX will be attempting something unprecedented in rocketry. Success is far from guaranteed and the worst possible failure mode could almost entirely destroy Starship’s only finished orbital launch site, explaining SpaceX’s unusual caution.

On January 23rd, Ship 24 and Booster 7 completed Starship’s first full wet dress rehearsal (a fueling and launch rehearsal test) on the first try – an extremely impressive achievement for any rocket, let alone the largest in history. With that combined test out of the way, the only unprecedented test standing between Starship and its first orbital launch attempt is a 33-engine Super Heavy static fire.

To reduce risk, Ship 24 was removed from Booster 7. Back at the factory, SpaceX needs to close a few gaps left in its heat shield, and will likely also conduct careful inspections to ensure that the Starship is ready for flight. Unburdened of Ship 24, Booster 7 may finally be on the cusp of the most challenging ground test in Starship and SpaceX history. SpaceX has scheduled 12-hour road closures that could be used for that purpose as early as January 30th, 31st, and February 1st.

Those road closures could be used for Ship 25 static fire testing instead of or in addition to Booster 7. The Super Heavy is also missing an important hydraulic power unit (HPU) that was removed before the wet dress rehearsal. It’s unclear if static fire testing can be conducted without that HPU (one of two), why it was removed, or how long replacing it will take, adding more uncertainty. Nonetheless, it still appears that SpaceX is no more than a few weeks away from Starship’s first 33-engine static fire attempt.

Tesla flexed the new features of the Model Y L with a dedicated media event at the company’s Diner on Santa Monica Boulevard in Los Angeles.

The Model Y L is the extended-wheelbase version of the all-electric crossover, which has been voted the best-selling car in the world on three occasions. The vehicle is already rolling off production lines at Gigafactory Texas, and first deliveries are slated to take place later this year.

Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990

Teslarati was invited to the event, but due to some scheduling conflicts, we could not make it to Los Angeles. Instead, we will have our hands on a media unit sometime in August, so we’ll be able to spend some more extended time with the Model Y L.

However, plenty of those who made it to LA shared some cool features that set the Model Y L apart from the Model Y.

Multi-Row Climate Control

Tesla fitted the Model Y L with full climate control on all three rows on the front screen. It can be adjusted by selecting which row you’d like to modify on the right-hand side of the touch screen:

Better Rear Window Visibility

One of the strangest things about the Model Y, especially the Juniper iteration, is the rear window has extremely limited visibility when looking into the rearview mirror.

Tesla has improved upon this with the Model Y L:

PowerShare will be included

Model Y L will come with PowerShare in North America, with an 11.5kW output to your home. Tesla said it would require Powerwall 3 for operation.

Wireless Charging Pad

There has been some speculation that Tesla would upgrade the wireless charging pads in the United States, but this is not the case.

Tesla owner fixes common feature complaint with crafty DIY retrofit

Tesla confirmed that it does not come with the cooled pads as the Y L in China does. This is because North America has not adopted Qi charging yet.

Thermal Management Improvements

These improvements in the Model Y L were seen with thermal management:

  • Up to 15% faster cabin cooling
  • +23% thermal efficiency gained in hot weather, 7 miles of real-world range gained
  • 8x more solar energy reflection off of glass roof
  • 30% reduction in solar energy entering the cabin

Demand

Tesla said the Model Y L is almost sold out in the U.S. It comes with

  • 1 year of FSD Supervised
  • 1 year of Supercharging
  • 1 year of Premium Connectivity
  • Free exterior paint color, interior, and wheel option at no additional cost

Tesla CEO Elon Musk denies ridiculous Gigafactory Shanghai rumor

Tesla CEO Elon Musk took to his social media platform X on Thursday night to deny a ridiculous rumor regarding the sale of the company’s Chinese vehicle production plant, Gigafactory Shanghai.

On Thursday, the Wall Street Journal, citing sources familiar with the matter, claimed in a scathing new report that Tesla was exploring a potential sale of the entire China business in an effort to help bolster a potential merger between SpaceX and Tesla.

Musk immediately denied the rumor not once but twice, initially calling it “fake news,” and then calling it “absurdly fake news” in a separate post just a few moments later:

The original poster of the Wall Street Journal article that Musk saw deleted the initial post sharing the headline and the rumored sale of Tesla’s China business.

The report seemed absolutely and unequivocally false to begin with; Tesla’s business in China is among the most important pieces of the company’s business. Not only does the factory supply vehicles for the domestic market, but also for various other markets in Asia and Europe.

China is also one of the largest automotive markets in the world, and Tesla has performed well there despite the robust competition.

The speculation regarding a Tesla and SpaceX merger has started to gain steam this year as the space exploration company went public just a month ago. There has been speculation that Musk will bridge all of his companies under one “umbrella company,” and analysts believe this could happen before the end of the decade.

The Tesla and SpaceX merger everyone is talking about is quietly building

This is the latest iteration of Musk’s very evident war on mainstream media. Reports regarding any of Musk’s companies are quick to get the dreaded “false” or “fake news” response from the CEO when they are unfounded.

Tesla AI boss reveals how big Optimus is going to get

Tesla’s Optimus chief corrected himself on X, confirming a staggering 10 million robot production target.

Tesla’s Optimus program has a new number attached to it, after Ashok Elluswamy, the executive who has run the humanoid robot program since June 2025, posted a three word correction on X Thursday, “Correction, 10 million robots.”

The line clarifies the long term annual capacity Tesla is building toward its planned second Optimus production line at Gigafactory Texas, a figure Musk has cited repeatedly since last year’s shareholder meeting.

The scale is worth noting, because ten million robots a year would mean Tesla building more units annually than most countries sell in new cars. Tesla has framed this as a second line, not the first. The buildout is happening in two phases: a roughly one million unit per year line inside Tesla’s Fremont factory, installed on the floor space vacated when Model S and Model X production ended earlier this year, and a much larger dedicated facility under construction at Giga Texas that broke ground on its first steel structure in May. That Texas facility is the one Elluswamy’s correction refers to, and is expected to reach volume production sometime in 2027.

Tesla Optimus project fires up as Musk sees production line progress

Elluswamy took over Optimus from Milan Kovac last summer and has spent the months since talking up the program’s trajectory. Elon Musk has also floated the ten million figure at Tesla’s 2025 shareholder meeting.

Ending Model S and Model X production to make room for the first Optimus line was one of the more consequential manufacturing decisions in the company’s recent history, retiring two flagship vehicles in favor of a robot that has yet to enter mass production. Musk has previously estimated per unit production costs at $20,000 to $25,000 once Tesla reaches a million units a year, though he hasn’t said what that cost looks like at ten times the volume.
