SpaceX attempts second Falcon fairing drop test with a helicopter and Mr. Steven

(Pauline Acalin)

Following a few days of rest in port, SpaceX fairing recovery vessel Mr. Steven has continued a likely campaign of controlled drop tests with a second fairing recovery attempt, using a helicopter, spotter plane, and support vessel to pick up a Falcon fairing and drop it, theoretically allowing it to paraglide into Mr. Steven’s net.

While it’s nearly impossible to determine what happened without line-of-sight visual confirmation or an official announcement from SpaceX, it appears that Mr. Steven kicked off real catch attempts on October 11th, evidenced by his close interaction with a Blackhawk helicopter over the course of an hour or so. Another similar attempt occurred today, October 17th, and culminated with Mr. Steven returning once more to Port of San Pedro with the same test-focused fairing half on board, albeit not resting in his retracted net.

After October 11th’s testing was completed, Mr. Steven returned to Port of San Pedro. On October 13th, he was docked at SpaceX’s Berth 240 facilities with net lowered and the test fairing half wrapped up on the docks, preventing confirmation of whether he carried the fairing half back from the testing region. A mid-sized barge also recently appeared at Berth 240 with a distinct Falcon fairing cradle onboard, perhaps explaining the presence of a tugboat (named Sir Richard) a few miles away from where this test campaign has been stationed – a barge would offer a flat, safe surface for a helicopter to hover over and pick up an unwieldy object such as a payload fairing.

Nearly identical to the October 11th test, Mr. Steven, tug Sir Richard, a Cessna chase plane, and a Blackhawk helicopter all converged around 100 miles southwest of Port of Los Angeles around 2pm PDT on October 17th prior to beginning recovery test operations. Mr. Steven and the tug Sir Richard – likely towing a barge being temporarily used to move a fairing half – arrived several hours beforehand at the test’s planned location.

 

Eventually, a UH-60A Blackhawk helicopter – the same helicopter used on October 11 – lifted off from Catalina Island’s Avalon airport, taking about half an hour to reach Mr. Steven and Sir Richard. Once there, the helicopter very distinctly slowed down, eventually hovering just ~20 feet off the surface of the ocean, if not outright landing or perching on the aforementioned barge under the tug’s control. After several minutes in that state, the Blackhawk lifted off and immediately began climbing, reaching a peak of ~11,000 ft before (presumably) dropping its fairing payload and immediately diving down to follow its descent.

It’s undoubtedly an imperfect fit, but the helicopter appeared to follow Mr. Steven very closely over the course of the recovery attempt, sticking just a ~1500 ft or less above and a few hundred feet beside him as he raced to catch the falling fairing half. In fact, at least as a very rough approximation, the helicopter’s descent may be useful to judge the fairing’s behavior while gliding: taking ~14 minutes to travel descend 11,000ft and travel perhaps 2 miles (~10,500ft) horizontally, the fairing would dropped at a reasonable 13.1 feet per second (~4 m/s) once its parafoil opened and seemed to travel approximately one foot forward for every one foot down, also known as a 1:1 glide slope ratio.

Depending on wind conditions, parafoils can nominally be expected to achieve average glide slope ratios between 0 (high winds; falling like a literal rock) and 4 (no winds; almost as good as a bad airplane), meaning that Falcon fairings – judging from tangential data gathered from the helicopter following its descent – fly much like a parafoil, which is to say not great but better than a brick. The trick with parafoil control – which includes tweaking angles of attack and glide slope – lies more in the art of trading forward velocity for vertical velocity (or vice versa) at key moments. Assuming their control mechanisms have enough authority, paragliding fairings could ‘flare’ as they near Mr. Steven’s net, essentially angling upwards to briefly hover before dropping quickly, maybe giving the boat enough time to swoop in and place its net just beneath it.

In this way, a parafoil’s flexible, inflated wing (airfoil, to be precise) can allow it to maneuver quite a lot like a bird, at least more so than most other methods of flying humans have access to. Time will tell if SpaceX is having any luck perfecting the guidance and recovery of Falcon fairings, particularly with this campaign of under-the-radar drop tests. Even if Mr. Steven returns with a fairing half resting in his net, it will be more than a little ambiguous if it was placed there or he caught it, and any certainty will rely on official confirmation from SpaceX itself.

Elon Musk teases Tesla Roadster unveiling once again

Published

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.

A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”

Musk agreed:

The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.

It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:

“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”

The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.

However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.

For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”

We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor

Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.

Published

Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”

The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.

SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.

Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.

Tesla wins three-year standoff against Sweden’s IF Metall union

Sweden’s IF Metall union has announced that it is ending all protests against Tesla, effective immediately.

The union said in a statement this morning:

“There seems to be no limits to the length Tesla would go to keep unions out of their operations. Unfortunately, they have managed to pay their way out in Sweden. At least that has given the former IF Metall members more money in their pocket, but the insecurity of not having a union or a collective agreement still remains.”

IF Metall has been after Tesla in Sweden for the past three years, attempting to push unionized operations into its factories. Tesla, on the other hand, has given its employees the chance to unionize in various markets. However, the organization says that Tesla has “bought out all of its striking members.”

“Today, we end our industrial action against Tesla. We do so because it can no longer have an effect – not because our principles have changed,” a written statement said.

Over the past three years, IF Metall has definitely been a thorn in the side of Tesla and its operations in Sweden. The primary strike started in October 2023, when IF Metall members at Tesla’s Swedish Service Centers refused to work.

IF Metall chair to Elon Musk: “Give us a chance” as Tesla Sweden strike hits 2 years

Strikes extended to blockades and work stoppages at non-Tesla-owned repair shops that service Teslas. This limited and stopped anything related to warranties, transport damage, and other work on Teslas ending, eliminating work arounds for customers.

Sympathy strikes followed, as postal workers, dock workers, electricians, and other tradesmen stopped working. Add in lawsuits and other pressures, and you get the full scope of what strategies the union has used against Tesla over the past several years.

But now, it’s all over.

“We will continue to defend the right of workers to organize. We will continue to fight for collective bargaining. And we will continue to stand in solidarity with workers and trade unions facing similar challenges elsewhere – just as you have stood with us,” IF Metall said.
