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

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.

Tesla China was able to sell 71,599 vehicles wholesale in June 2025, reversing eight consecutive months of year-over-year declines. The figure marks a 0.83% increase from the 71,599 vehicles sold wholesale in June 2024 and a 16.1% jump compared to the 61,662 vehicles sold wholesale in May. 

Tesla China’s June numbers were released by the China Passenger Car Association (CPCA) on Tuesday.

Tesla China’s June results in focus

Tesla produces both the Model 3 and Model Y at its Shanghai Gigafactory, which serves as the company’s primary vehicle export hub. Earlier this year, Tesla initiated a changeover for its best-selling vehicle, the Model Y, resulting in a drop in vehicle sales during the first and second quarters.

Tesla’s second-quarter China sales totaled 191,720 units including exports. While these numbers represent a 6.8% year-over-year decline for Tesla China, Q2 did show sequential improvement, rising about 11% from Q1 2025, as noted in a CNEV Post report.

For the first half of the year, Tesla sold 364,474 vehicles wholesale. This represents a 14.6% drop compared to the 426,623 units sold wholesale in the first half of 2024.

China’s competitive local EV market

Tesla’s position in China is notable, especially as the new Model Y is gaining ground in the country’s BEV segment. That being said, Tesla is also facing competition from impressive local brands such as Xiaomi, whose new YU7 electric SUV is larger and more affordable than the Model Y. 

The momentum of the YU7 is impressive, as the vehicle was able to secure 200,000 firm orders within three minutes and over 240,000 locked-in orders within 18 hours. Xiaomi’s previous model, the SU7 electric sedan, which is aimed at the Tesla Model 3, also remains popular, with June deliveries surpassing 25,000 units for the ninth straight month.

While China’s EV market is getting more competitive, Tesla’s new Model Y is also ramping its production and deliveries. Needless to say, Tesla China’s results for the remaining two quarters of 2025 will be very interesting.

Tesla reveals it is using AI to make factories more sustainable: here’s how

Tesla is using AI in its Gigafactory Nevada factory to improve HVAC efficiency.

Tesla has revealed in its Extended Impact Report for 2024 that it is using Artificial Intelligence (AI) to enable its factories to be more sustainable. One example it used was its achievement of managing “the majority of the HVAC infrastructure at Gigafactory Nevada is now AI-controlled” last year.

In a commitment to becoming more efficient and making its production as eco-friendly as possible, Tesla has been working for years to find solutions to reduce energy consumption in its factories.

For example, in 2023, Tesla implemented optimization controls in the plastics and paint shops located at Gigafactory Texas, which increased the efficiency of natural gas consumption. Tesla plans to phase out natural gas use across its factories eventually, but for now, it prioritizes work to reduce emissions from that energy source specifically.

It also uses Hygrometric Control Logic for Air Handling Units at Giafactory Berlin, resulting in 17,000 MWh in energy savings each year. At Gigafactory Nevada, Tesla saves 9.5 GWh of energy through the use of N-Methylpyrrolidone refineries when extracting critical raw material.

Perhaps the most interesting way Tesla is conserving energy is through the use of AI at Gigafactory Nevada, as it describes its use of AI to reduce energy demand:

“In 2023, AI Control for HVAC was expanded from Nevada and Texas to now include our Berlin-Brandenburg and Fremont factories. AI Control policy enables HVAC systems within each factory to work together to process sensor data, model factory dynamics, and apply control actions that safely minimize the energy required to support production. In 2024, this system achieved two milestones: the majority of HVAC infrastructure at Gigafactory Nevada is now AI-controlled, reducing fan and thermal energy demand; and the AI algorithm was extended to manage entire chiller plants, creating a closed-loop control system that optimizes both chilled water consumption and the energy required for its generation, all while maintaining factory conditions.”

Tesla utilizes AI Control “primarily on systems that heat or cool critical factory production spaces and equipment.” AI Control communicates with the preexisting standard control logic of each system, and any issues can be resolved by quickly reverting back to standard control. There were none in 2024.

Tesla says that it is utilizing AI to drive impact at its factories, and it has proven to be a valuable tool in reducing energy consumption at one of its facilities.
