First sounds of wind on Mars captured by NASA’s Insight Lander
This fresh in from the Elysium Planitia of Mars: the sound of wind from an alien world. On its 10th day as a new resident of the red planet, NASA’s InSight lander’s pressure sensor transmitted air vibration data from its trembling solar panels, representing a steady breeze about 99 million miles away. The combination of photos sent back from the craft with the sound of Martian wind gives Earth residents a unique moment to feel like they’ve joined the craft themselves. “It’s fun to imagine that I’m there,” mused Don Banfield during a JPL media teleconference discussing the recording. Banfield is InSight’s Auxiliary Payload Sensor Subsystem (APSS) Science Lead.
InSight, short for “Interior Exploration using Seismic Investigations, Geodesy and Heat Transport”, launched aboard an Atlas V rocket on May 5, 2018 and successfully landed on the Martian surface on November 26, 2018. The craft is a seismic investigator sent to study the red planet’s core, eventually drilling 10-16 feet down into its crust to gather geographical data. The craft’s landing event was live streamed online for viewers around the world, greeting Earthlings with a photo of its new home’s surface shortly after. It sent back more photos of the surrounding area prior to the wind recording.
The thin CO2 atmosphere on Mars doesn’t translate high sounds well, so the recorded vibrations from InSight’s pressure sensor are low on the audio spectrum, under 50 Hz, thus difficult to hear. However, after the frequency was increased by a factor of 100 (raised two octaves), it became possible to hear what sounds like a steady wind blowing across the regolith. Dust devils tracked in the area moving across the Martian surface had motion consistent with the wind recordings, thus confirming what was being heard by InSight’s scientists.
The way InSight picks up and translates sound is similar to how a human ear works: Air pressure vibrates the eardrum, then that vibration pattern is sent through the inner ear bones to the cochlea which has tiny hairs translating the vibrations into electrical signals sent to the brain. InSight’s solar panels are like its eardrums, the spacecraft structure itself like its inner ear, its instruments like its cochlear, and its electronic box translating and transmitting signals is like brain. The “sounds” we hear from Mars are translated data from wind-caused vibrations.
Ironically enough, wind noise is actually not a particularly desired outcome from InSight’s instruments. According to the scientists participating in NASA’s teleconference discussing the event, the inlet for the pressure sensor was specifically designed to minimize any chatter from air movement. Also, the placement of InSight’s seismographic gear will be based on the best area to reduce input from the lander’s interaction with the vibrations it’s recording, i.e., the lander’s movement from seismic events. It should be noted, though, the Martian wind gracing our human ears for the first time is only a taste of what’s to come from InSight’s instruments.
Once the wind and thermal shield (the white dome in the photos) has been lifted from the lander in a few weeks, all of InSight’s instruments will be exposed to the Martian environment for data collection. For now, the lander’s Earth-based team is first focusing on understanding the area the craft is in to pick the best place to set its instruments. After the main mission begins, however, a full study of Mars’ atmosphere will be underway and we could hear, among other natural events, the sounds of exploding meteors.
While wind may be a unique sound to hear on an alien world, it’s not the first time a NASA craft has entertained our ears and imaginations. Electromagnetic vibrations have been recorded all across our solar system, perhaps the most famous of which originated from the Voyager 1 spacecraft launched in 1977. The data collected from the craft’s radio-capturing instruments has been converted into audio files – you can even find a full album’s worth of the sounds on a variety of streaming sites. Some of the recordings are meditation-worthy, others a touch unnerving. We humans have additionally added some recordings of our own to space via Voyager’s famous “golden record”, the sounds of which are also available for listening online.
If you’re craving a full Martian soundtrack, you’ll be happy to know that NASA’s Mars 2020 rover is planned to provide just that. It will have two microphones on board, one of which will record the actual landing of the rover. Combined with telemetry data and surface photographs, Mars is on its way to its own documentary with inputs completely provided “on-location”. Stay tuned!

Tesla Supercharger access has proven to be a challenge for one company
Interestingly, it seems to be the Volkswagen brand specifically that is having issues with compatibility with Tesla Superchargers. Other brands under the VW umbrella, like Audi and Porsche, have already gained access to the charging network.
Tesla Supercharger access has proven to be quite the challenge for one company, as it continues to delay the date that it will enable its owners to charge at the most expansive network in the world.
Tesla Superchargers have been opening up to other brands for well over a year, and many car companies that are manufacturing electric vehicles now have access to the vast network that has over 70,000 locations worldwide.
Tesla to launch Supercharger access for VW owners later this year
However, one brand has experienced some issues with what it is calling “technical challenges,” specifically failing to enable cross-compatibility between its vehicles and Tesla Superchargers.
Volkswagen has had to delay its ability to enable customers to charge at Superchargers because there have been some difficulties getting things to run smoothly. A report from PCMag cites a quote from a Volkswagen spokesperson who said there are still plans to deliver this year, but there have been some delays:
“Volkswagen looks forward to making it possible for ID. Buzz and ID.4 vehicle owners to gain access to the Tesla NACS Partner Superchargers. The timeline has been delayed by technical challenges, and we ask for customers’ patience. We still expect to deliver access this year.”
Interestingly, it seems to be the Volkswagen brand specifically that is having issues with compatibility with Tesla Superchargers. Other brands under the VW umbrella, like Audi and Porsche, have already gained access to the charging network.
Volkswagen EV owners will need to use an official VW adapter to access the Tesla Supercharger Network once the issues are resolved. It still plans to launch access to its owners later this year, but its spokesperson did not announce any planned timeline.

Tesla Giga Berlin makes big move amid strong sales and demand
“We currently have very good sales figures and have therefore revised our production plans for the third and fourth quarters upwards.”
Tesla is making a big move at its factory in Germany, known as Giga Berlin, as managers at the plant have indicated the company plans to increase its production rate for the remainder of the year.
Giga Berlin is responsible for manufacturing Model Y vehicles for several markets worldwide, including those outside of Europe. It was opened in March 2022, and it recently built its 500,000th Model Y in March and its 100,000th new Model Y just three weeks ago.
Due to some encouraging sales figures in the markets it provides vehicles for, Tesla said it is planning to increase production at the factory for the remainder of the year.
Andrè Thierig, plant manager at Giga Berlin, said to German news outlet DPA on Sunday that market data has encouraged a move to be made regarding the production at the factory:
“We currently have very good sales figures and have therefore revised our production plans for the third and fourth quarters upwards.”
It is interesting to see this kind of narrative from Thierig, especially as data has shown Tesla has struggled in various markets, including Germany, this year.
Sales drops have been reported, but other markets are holding strong, especially those in Northern Europe, such as Norway, where the Model Y saw a nearly 39 percent increase in sales in August compared to the same month the previous year.
Gigafactory Berlin supplies vehicles for other markets, such as Canada, Australia, and New Zealand, which are strategically important to avoid tariffs. It also builds cars for the Middle East.
Thierig reiterated this point during the interview with DPA:
“We supply well over 30 markets and definitely see a positive trend there.”

Tesla analyst says Musk stock buy should send this signal to investors
“With Musk’s (Tesla stock) purchase, combined with the upward momentum for delivery expectations and robotaxi rollout, we are becoming more bullish.”
Tesla CEO Elon Musk purchased roughly $1 billion in Tesla shares on Friday, and analysts are now breaking down the move as the stock is headed upward.
One of them is William Blair analyst Jed Dorsheimer, who said in a new note to investors on Monday that Musk’s move should send a signal of confidence to stock buyers, especially considering the company’s numerous catalysts that currently exist.
Elon Musk just bought $1 billion in Tesla stock, his biggest purchase ever
Dorsheimer said in the note:
“With Musk’s (Tesla stock) purchase, combined with the upward momentum for delivery expectations and robotaxi rollout, we are becoming more bullish. This purchase is Musk’s first buy since 2020. To us, this sends a strong signal of confidence in the most important part of Tesla’s future business, robotaxi.”
Musk putting an additional $1 billion back into the company in the form of more stock ownership is obviously a huge vote of confidence.
He knows more than anyone about the progress Tesla has made and is making on the Robotaxi platform, as well as the company’s ongoing efforts to solve vehicle autonomy. If he’s buying stock, it is more than likely a good sign.
Tesla has continued to expand its Robotaxi platform in a number of ways. The project has gotten bigger in terms of service area, vehicle fleet, and testing population. Tesla has also recently received a permit to test in Nevada, unlocking the potential to expand into a brand-new state for the company.
In the note, Dorsheimer also touched on Musk’s recent pay package, revealing that William Blair recently met with Tesla’s Board of Directors, who gave the firm some more color on the situation:
“We recently participated in a meeting with Tesla’s board of directors to discuss the details of Musk’s performance package. The board is confident of its position in the Delaware case and anticipates a verdict by end of year. It does not expect a similar situation to occur under new Texas jurisdiction. Musk has the board’s full support, and we expect he’ll get more than enough shareholder support for this to pass with flying colors.”
Tesla stock is up over 6 percent so far today, trading at $421.50 at the time of publication.
