SpaceX Starship prototype kicks off gauntlet of tests for the fifth time

Hours after a successful Falcon 9 launch, a SpaceX Starship prototype has kicked off a challenging gauntlet of tests for the fifth time in hopes of becoming the first to take flight.

Five days after the ~30m (~100 ft) tall steel rocket was transported from the factory to the launch pad, SpaceX has fully integrated it with a brand new launch mount – built from scratch after operator error caused Starship SN4 to explode and destroy the prior mount. Assembled and outfitted with great haste, the new mount was completed just a day or two before Starship SN5 was moved to the pad and installed on top of it.

Triggered by a quick disconnect umbilical panel fuel leak that effectively caused a bomb-like fuel-air explosion, Starship SN4’s May 29th demise occurred shortly after a Raptor static fire test that was likely one of the last hurdles standing between SpaceX and the first full-scale Starship flight test. That fated static fire itself occurred a single day after SpaceX crossed a major regulatory milestone with an official FAA launch license for an effectively unlimited number of suborbital Starship flights. Now transformed into a pile of scorched scrap metal, Starship SN4 has passed the torch to Starship SN5.

Effectively identical to the gauntlet of tests Starship SN4 completed in the weeks prior to its destruction, Starship SN5 has kicked off its own test campaign with an ambient pressure test – a low-risk method of checking a pressure vessel for leaks. Starship SN5 apparently passed that first test without issue and SpaceX is now in the midst of loading the rocket tank section with cryogenic liquid nitrogen as a chemically neutral and nonexplosive stand-in for live liquid oxygen and methane propellant. (SN4 serves as a perfect illustration of why initial cryo proof tests are performed with LN2 instead of real propellant.)

SN4 was actually the first full-scale Starship prototype to survive a full cryogenic proof test, achieving 7.5 bar (~110 psi), so SN5’s success is far from guaranteed. Still, given SpaceX’s iterative, clockwork-like approach to development means that it’s far more likely than not that Starship SN5 will pass all the tests that its predecessor did – and then some.

If Starship SN5’s cryo proof is successful, SpaceX has a few options available. Depending on the level of confidence in SN5, SpaceX could proceed directly into installing a single Raptor engine on the rocket’s triple-engine thrust structure and move on to wet dress rehearsals (WDRs) with methane and oxygen propellant. If a more cautious approach is preferred, SpaceX could perform a WDR or two before installing a Raptor engine. Either way, once the WDR phase is complete, Starship SN5 can begin live Raptor engine testing, starting with turbopump prime and preburner tests and culminating in one or several static fires.

Finally, once preburner and static fires have been completed without issue, SpaceX can begin to seriously prepare SN5 for its inaugural hop test, likely targeting an altitude of ~150m (~500 ft) before landing a few hundred feet from the launch mount. For now, many steps remain in the interim before Starship SN5 is even close to a hop test, but it shouldn’t take long to find out how long we’ll have to wait.

Blue Origin has revealed plans to develop New Glenn 9×4, a “super heavy” rocket designed to deliver 70 metric tons to low-Earth orbit and directly compete with SpaceX’s Starship. 

The announcement followed the company’s successful NG-2 launch on November 13, which deployed NASA’s ESCAPADE (Escape and Plasma Acceleration Dynamics Explorers) Mars mission and landed the first stage.

Upgraded engines and reusability

As noted in a Universe Today report, Blue Origin will roll out upgraded BE-4 engines producing 640,000 lbf each, up from 550,000 lbf, starting with NG-3. This should boost the New Glenn rocket’s total first-stage thrust to 4.5 million pounds. Upper-stage BE-3U engines are expected to improve from 320,000 lbf to 400,000 lbf over the next few flights as well.

“These enhancements will immediately benefit customers already manifested on New Glenn to fly to destinations including low-Earth orbit, the Moon, and beyond. Additional vehicle upgrades include a reusable fairing to support increased flight rates, an updated lower-cost tank design, and a higher-performing and reusable thermal protection system to improve turnaround time,” Blue Origin noted. 

New Glenn “Super Heavy” 9×4

The super-heavy New Glenn 9×4, with nine BE-4s on the booster, four BE-3Us on the upper stage, will feature an 8.7-meter payload fairing. Blue Origin expects New Glenn 9×4 to be capable of transporting 70 metric tons to LEO, 14 tons to GSO, and 20 tons to trans-lunar injection, as noted by the company in a blog post. This is very impressive, as New Glenn 9×4’s capacity exceeds Falcon Heavy, SpaceX’s largest rocket available to consumers today. Falcon Heavy is capable of carrying up to 64 metric tons to low Earth orbit in a fully expendable configuration.

That being said, SpaceX’s Starship’s capacity is extremely impressive. As per SpaceX, Starship is designed to be capable of carrying up to 100-150 metric tonnes to orbit in its fully reusable configuration. At its expendable configuration, Starship’s capacity enters unheard-of territory, with SpaceX stating that the vehicle could transport 250 metric tonnes of cargo.

Tesla FSD approved for testing in Nacka, Sweden, though municipality note reveals aggravating detail

Nacka, Sweden, a municipality just a few miles from Stockholm, has given its approval for FSD tests.

Tesla has secured approval for FSD testing in an urban environment in Sweden. As per recent reports from the Tesla community, Nacka, Sweden, a municipality just a few miles from Stockholm, has given its approval for FSD tests. 

A look at the municipality’s note regarding FSD’s approval, however, reveals something quite aggravating. 

FSD testing approval secured

As per Tesla watcher and longtime shareholder Alexander Kristensen, Nacka is governed by the Moderate Party. The shareholder also shared the municipality’s protocol notes regarding approval for FSD’s tests. 

“It is good that Nacka can be a place for test-driving self-driving cars. This is future technology that can both facilitate mobility and make transportation cheaper and more environmentally friendly,” the note read. 

The update was received positively by the Tesla community on social media, as it suggests that the electric vehicle maker is making some legitimate headway in releasing FSD into the region. Sweden has been particularly challenging as well, so securing approval in Nacka is a notable milestone for the company’s efforts.

Aggravating details

A look at the notes from Nacka shows that FSD’s proposed tests still met some opposition from some officials. But while some critics might typically point to safety issues as their reasons for rejecting FSD, those who opposed the system in Nacka openly cited Tesla’s conflict with trade union IF Metall in their arguments. Fortunately, Nacka officials ultimately decided in Tesla’s favor as the company’s issues with the country’s unions are a completely different matter.

“The left-wing opposition (S, Nackalistan, MP and V) voted no to this, referring to the fact that the applicant company Tesla is involved in a labor market conflict and does not want to sign a collective agreement. We believe that this is not an acceptable reason for the municipality to use its authority to interfere in a labor law conflict.

“Signing a collective agreement is not an obligation, and the company has not committed any crime. The municipality should contribute to technological development and progress, not work against the future,” the note read.

Norway’s annual roundup of the best car purchases featured Tesla’s two main sellers this year, with the Model 3 and Model Y securing top positions in their respective segments. 

Despite growing competition from European and Korean brands, both models stood out for their balance of price, performance, and everyday usability. The verdict comes as electric vehicle adoption remained above 95% of new vehicle sales in the country.

Tesla Model 3 strengthens its value position

Among compact EVs, the Tesla Model 3 maintained its position as the best overall buy thanks to its strong blend of performance, efficiency, and updated features. Reviewers noted that every trim offered compelling value, especially with the all-electric sedan’s improved cabin ergonomics and the return of the turn-signal stalk, which was one of the few previous complaints among drivers. 

The Model 3’s mix of long-range capability, low operating costs, and responsive handling has continued to set the benchmark for compact EVs in Norway. While competitors from Hyundai, Volkswagen, and Peugeot have narrowed the gap, Tesla’s price-to-capability ratio has remained difficult to beat in this segment, Motor.no reported.

“The Model 3 clearly offers the best value for money in the compact class, no matter which version you choose. Now it also gets the turn signal lever back. This eliminates one of the few flaws in a driving environment that many believe is the best on the market,” the publication wrote.

Tesla Model Y claims its crown

The Tesla Model Y emerged as Norway’s top family-car purchase this year. The latest refresh introduced improvements in ride quality, styling, and interior materials, allowing the Model Y to deliver a more premium driving experience without a substantial price increase. 

Reviewers praised its spacious cabin, strong safety profile, and practical range, all of which reinforced its appeal for families needing an all-purpose electric crossover. The Model Y remains especially notable given its continued popularity in Norway even as Tesla faces declining sales in other global markets.

“The Model Y is back as the winner in the family class. The upgrade in the new year was even more extensive than expected. It is a slightly more elegant and significantly more comfortable Model Y that solidifies its position as Norway’s best car purchase in the most important class,” the Norwegian motoring publication noted.
