According to SpaceX CEO Elon Musk, the company’s next major Starhopper flight test is still awaiting FAA approval due to a need for more hazard analysis, presumably required because Starhopper will be traveling much higher than before.

On August 9th, SpaceX completed a routine wet dress rehearsal (WDR) with Starhopper, loading the vehicle with propellant and fluids and replicating a launch countdown up to the point of Raptor ignition. Starhopper remains untethered in a sign that SpaceX doesn’t have plans for a static fire test before the low-fidelity rocket prototype’s next flight milestone. Originally scheduled for August 12th, that milestone – a 200m (650 ft) hop test – has been indefinitely delayed as SpaceX awaits an updated permit from the Federal Aviation Administration (FAA).

The oddity of the apparent difficulty SpaceX is having with the FAA’s experimental permit process is deepened by the fact that Starhopper is already permitted by the FAA and demonstrated its first successful flight just a few weeks ago, on July 25th. On top of the fact that the local Boca Chica and Brownsville, Texas airspace tends to be extremely quiet, it’s unclear what exactly is holding up SpaceX, the FAA, or both in what should otherwise be a relatively streamlined process.

A few weeks ago, after one false start on July 24th, Starhopper performed its first untethered flight ever on July 25th, successfully demonstrating its integrated steel propellant tanks, avionics, software, and Raptor propulsion over the course of 20 or so seconds of flight. Starhopper’s inaugural flight was delayed at least several weeks by a major bug with SpaceX’s next-gen Raptor engine, described by Elon Musk as a problem with a certain frequency of vibration (i.e. mechanical resonance).

According to Musk, said resonance failure mode was effectively solved with unspecified modifications made to the sixth Raptor engine produce (Raptor SN06). That engine became the first to successfully pass SpaceX’s regime of pre-hop static fires in McGregor, Texas around July 10th and was shipped south to Boca Chica and installed on Starhopper scarcely 24 hours later.

Assuming those vibration issues have been completely quashed, Musk has also stated that SpaceX is aiming to produce as many as two Raptor engines per day by the end of 2019. It’s believed that all engines preceding SN06 (SN01-05) were either damaged or destroyed during testing, be that a result of intentional testing-to-destruction or anomalous behavior during certain test regimes. It should be noted that full-scale Raptor is still undoubtedly in development and hardware failure during developmental testing is more predictable and valuable than it might seem. As long as the program can handle it, ‘hardware-rich’ development (i.e. moving fast and breaking things) can be equally – if not more – valuable than an extremely cautious get-it-right-the-first-time approach.

Regardless, once SpaceX’s propulsion engineering team is confident that the more major bugs that plagued early Raptor engines have been alleviated, they will likely give the go-ahead for the engine manufacturing team to begin ramping production rates. Musk believes that SpaceX could be ready for the first test flights of either or both of the company’s orbital Mk1 and Mk1 Starship prototypes as early as mid-September, milestones that will eventually require three sea-level Raptor engines and up to three vacuum Raptor engines per rocket.

Meanwhile, although SpaceX has yet to begin assembling the first Super Heavy booster(s), said boosters will require dozens of Raptor engines each for their first flights. Musk says that SpaceX will start out with something like 20 Raptor engines per booster to minimize losses and disruption in the event of a catastrophic failure, eventually expanding to as many as 35 engines per booster as confidence grows.

For now, Starhopper’s next flight test was scheduled from August 16th through the 18th but has since been tentatively rescheduled to Aug. 19-21. Starhopper will remain grounded until the FAA is satisfied with SpaceX’s updated hazard analyses for the rocket’s 200m flight test.

Blue Origin announces Super-Heavy New Glenn 9×4 to Rival SpaceX Starship

The announcement followed the company’s successful NG-2 launch on November 13.

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.
