SpaceX’s upgraded Super Heavy booster sails through first major test

Published

on

SpaceX’s first upgraded 33-engine Super Heavy booster appears to have passed a crucial test with surprising ease, boding well for a smooth qualification process.

Attempting that test so early on did not appear to be SpaceX’s initial plan. Instead, shortly before Super Heavy Booster 4’s third and likely final removal from Starbase’s ‘orbital launch mount’ (OLM) on March 24th, SpaceX transported a massive structural test stand from a Starbase storage yard to the orbital launch site (OLS), where technicians have focused on modifying nearby ground systems to support apparent structural testing of Super Heavy Booster 7. As of March 31st, all available evidence suggested that SpaceX was preparing that stand to verify Booster 7’s mechanical strength and simulate the major stresses it might experience before investing a significant amount of time and resources in qualification testing.

However, SpaceX appeared to change its plans at the last minute.

Instead of starting with structural testing, after a brief two-day pause, SpaceX rolled Super Heavy B7 into place and craned the giant booster onto the orbital launch mount on April 2nd. On April 3rd, the launch mount’s “quick disconnect” device connected Super Heavy to the pad’s ground systems. On April 4th, just two days after its installation on the OLM, Super Heavy B7 kicked off the first in a series of qualification tests that will determine when or if the booster ultimately supports Starship’s first orbital launch attempt.

If testing goes perfectly, SpaceX CEO Elon Musk recently stated that Starship and Super Heavy – likely Ship 24 and Booster 7 – could be ready for an inaugural orbital launch attempt as early as May 2022. SpaceX appears to have leaped headfirst into Super Heavy Booster 7 qualification testing in a move that significantly increases the likelihood of meeting that extremely ambitious schedule. Normally, with a first-of-its-kind prototype debuting multiple significant design changes, SpaceX would start slow, possibly beginning with a basic pneumatic proof test to verify structural integrity at flight pressures – about 6.5-8.5 bar (95-125 psi) – with benign nitrogen gas before calling it a day.

With Booster 7, SpaceX likely still performed a quick pneumatic proof but then immediately proceeded into a full-scale cryogenic proof test. With Super Heavy B4, for example, SpaceX performed several increasingly ambitious cryogenic proof tests, filling the booster more and more each attempt but never actually topping it off. On Booster 7’s very first day of testing and first cryogenic proof attempt, SpaceX fully loaded the upgraded Super Heavy with a cryogenic fluid (likely liquid nitrogen) in just two hours – all with no significant unplanned holds (pauses).

In those two hours, SpaceX likely loaded Super Heavy B7’s liquid methane (LCH4) and oxygen (LOx) tanks with roughly 3400 metric tons (~7.5M lb) of liquid nitrogen (LN2) – not far off what Super Heavy would actually weigh at liftoff. At the peak of the test, Booster 7 was almost entirely covered in a thin layer of ice produced as the cryogenic liquid inside its tanks froze water vapor in the humid South Texas air onto its skin – an effect that effectively turns uninsulated cryogenic rockets into giant fill gauges. On top of running into no apparent issues, Super Heavy B7’s first cryogenic proof is also the first time any Super Heavy prototype has been fully filled during testing – an important milestone for any rocket prototype, let alone the largest rocket booster ever built.

Completing a full cryogenic proof test on its first try makes Booster 7 fairly unique among all Starship prototypes – not just Super Heavies. The contrast with Booster 4, which barely completed a handful of partial cryogenic proof tests in more than half a year spent at Starbase’s orbital launch site, is also extremely encouraging, suggesting that Booster 7 won’t be sitting inactive for months at a time.

Still, cryogenic proofing is just one of several important tests Booster 7 needs to complete. Even if the first test was nearly perfect and SpaceX doesn’t attempt one or several more cryoproofs with higher tank pressures or other tweaked variables, Super Heavy B7 needs to complete wet dress rehearsal testing (WDR) with flammable LCH4/LOx propellant and demonstrate autogenous pressurization (using heated propellant gas to pressure its tanks). At some point, SpaceX will also need to install a full 33 Raptor V2 engines on the booster and seal off the whole engine section and each Raptor with a heat shield.

Depending on how many Raptor V2 engines are available, SpaceX could begin static fire testing with just a few engines installed and shielded and then install the rest of the engines and heat shield later on. On the other hand, performing static fires without a full heat shield could risk damaging unprotected cabling or other subsystems, in which case wet dress rehearsal testing would likely follow immediately after cryoproofing and before engine or shield installation. After being skipped over, the structural test stand may also factor into Booster 7 qualification sometime before engine installation.

All told, plenty of uncertainty remains, but Super Heavy B7’s auspicious start suggests that the Booster 4 experience is far from a template and that SpaceX is much less interested in wasting time this time around.

Elon Musk hints Tesla investors will be rewarded heavily

“Hold onto your Tesla stock. It’s going to be worth a lot, I think. That’s my bet,” Musk said.

Elon Musk recently hinted that he believes Tesla investors will be rewarded heavily if they continue to hold onto their shares, and he reiterated that in a new interview that the company released on its social accounts this week.

Musk is one of the most successful CEOs in the modern era and has mammothed competitors on the Forbes Net Worth List over the past year as his holdings in his various companies have continued to swell.

Tesla investors, especially those who have been holding shares for several years, have also felt substantial gains in their portfolios. Over the past five years, the stock is up over 78 percent. Since February 2019, nearly seven years ago to the day, the stock is up over 1,800 percent.

Musk said in the interview:

“Hold onto your Tesla stock. It’s going to be worth a lot, I think. That’s my bet.”

It’s no secret Musk has been extremely bullish on his own companies, but Tesla in particular, because it is publicly traded.

However, the company has so many amazing projects that have an opportunity to revolutionize their respective industries. There is certainly a path to major growth on Wall Street for Tesla through its various future projects, including Optimus, Cybercab, Semi, and Unsupervised FSD.

  • Optimus (Tesla’s humanoid robot): Musk has discussed its potential for tasks like childcare, walking dogs, or assisting elderly parents, positioning it as a massive long-term driver of company value.
  • Cybercab (Tesla’s robotaxi/autonomous ride-hailing vehicle): a fully autonomous vehicle geared specifically for Tesla’s ride-sharing ambitions.
  • Semi (Tesla’s electric truck, with mentions of expansion, like in Europe): brings Tesla into the commercial logistics sector.
  • Unsupervised FSD (Full Self-Driving software achieving full autonomy without human supervision): turns every Tesla owner’s vehicle into a fully-autonomous vehicle upon release

These projects specifically are some of the highest-growth pillars Tesla has ever attempted to develop, especially in Musk’s eyes, as he has said Optimus will be the best-selling product of all-time.

Many analysts agree, but the bullish ones, like Cathie Wood of ARK Invest, are perhaps the one who believes Tesla has incredible potential on Wall Street, predicting a $2,600 price target for 2030, but this is not even including Optimus.

She told Bloomberg last March that she believes that the project will present a potential additive if Tesla can scale faster than anticipated.

Tesla’s new Cybertruck offering has had its delivery date pushed back once again. This is now the second time, and deliveries for the newest orders are now pushed well into 2027.

According to Tesla’s Online Design Studio, the new All-Wheel-Drive Cybertruck will now be delivered in April 2027. Earlier orders are still slated for early this Summer, but orders from here on forward are now officially pushed into next year:

Just three days ago, the initial delivery date of June 2026 was pushed back to early Fall, and now, that date has officially moved to April 2027.

The fact that Tesla has had to push back deliveries once again proves one of two things: either Tesla has slow production plans for the new Cybertruck trim, or demand is off the charts.

Judging by how Tesla is already planning to raise the price based on demand in just a few days, it seems like the company knows it is giving a tremendous deal on this spec of Cybertruck, and units are moving quickly.

That points more toward demand and not necessarily to slower production plans, but it is not confirmed.

Tesla Cybertruck’s newest trim will undergo massive change in ten days, Musk says

Tesla is set to hike the price on March 1, so tomorrow will be the final day to grab the new Cybertruck trim for just $59,990.

It features:

  • Dual Motor AWD w/ est. 325 mi of range
  • Powered tonneau cover
  • Bed outlets (2x 120V + 1x 240V) & Powershare capability
  • Coil springs w/ adaptive damping
  • Heated first-row seats w/ textile material that is easy to clean
  • Steer-by-wire & Four Wheel Steering
  • 6’ x 4’ composite bed
  • Towing capacity of up to 7,500 lbs
  • Powered frunk

Interestingly, the price offering is fairly close to what Tesla unveiled back in late 2019.

Elon Musk has clarified when SpaceX will first attempt to catch Starship’s upper stage with its launch tower. The CEO’s update provides the clearest teaser yet for the spacecraft’s recovery roadmap.

Musk shared the details in recent posts on X. In his initial post, Musk confirmed that Starship V3 Ship 1 (SN1) is headed for ground tests and expressed strong confidence in the updated vehicle design.

“Starship V3 SN1 headed for ground tests. I am highly confident that the V3 design will achieve full reusability,” Musk wrote.

In a follow-up post, Musk addressed when SpaceX would attempt to catch the upper stage using the launch tower’s robotic arms.

“Should note that SpaceX will only try to catch the ship with the tower after two perfect soft landings in the ocean. The risk of the ship breaking up over land needs to be very low,” Musk clarified. 

His remarks suggest that SpaceX is deliberately reducing risk before attempting a tower catch of Starship’s upper stage. Such a milestone would mark a major step towards the full reuse of the Starship system.

SpaceX is currently targeting the first Starship V3 flight of 2026 this coming March. The spacecraft’s V3 iteration is widely viewed as a key milestone in SpaceX’s long-term strategy to make Starship fully reusable. 

Starship V3 features a number of key upgrades over its previous iterations. The vehicle is equipped with SpaceX’s Raptor V3 engines, which are designed to deliver significantly higher thrust than earlier versions while reducing cost and weight.

The V3 design is also expected to be optimized for manufacturability, a critical step if SpaceX intends to scale the spacecraft’s production toward frequent launches for Starlink, lunar missions, and eventually Mars.
