First sounds of wind on Mars captured by NASA’s Insight Lander

Published

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 analyst claims another vehicle, not Model S and X, should be discontinued

Tesla analyst Gary Black of The Future Fund claims that the company is making a big mistake getting rid of the Model S and Model X. Instead, he believes another vehicle within the company’s lineup should be discontinued: the Cybertruck.

Black divested The Future Fund from all Tesla holdings last year, but he still covers the stock as an analyst as it falls in the technology and autonomy sectors, which he covers.

In a new comment on Thursday, Black said the Cybertruck should be the vehicle Tesla gets rid of due to the negatives it has drawn to the company.

The Cybertruck is also selling in an underwhelming fashion considering the production capacity Tesla has set aside for it. It’s worth noting it is still the best-selling electric pickup on the market, and it has outlasted other EV truck projects as other manufacturers are receding their efforts.

Black said:

IMHO it’s a mistake to keep Tesla Cybertruck which has negative brand equity and sold 10,000 units last year, and discontinue S/X which have strong repeat brand loyalty and together sold 30K units and are highly profitable. Why not discontinue CT and covert S/X to be fully autonomous?”

On Wednesday, CEO Elon Musk confirmed that Tesla planned to transition Model S and Model X production lines at the Fremont Factory to handle manufacturing efforts of the Optimus Gen 3 robot.

Musk said that it was time to wind down the S and X programs “with an honorable discharge,” also noting that the two cars are not major contributors to Tesla’s mission any longer, as its automotive division is more focused on autonomy, which will be handled by Model 3, Model Y, and Cybercab.

The news has drawn conflicting perspectives, with many Tesla fans upset about the decision, especially as it ends the production of the largest car in the company’s lineup. Tesla’s focus is on smaller ride-sharing vehicles, especially as the vast majority of rides consist of two or fewer passengers.

The S and X do not fit in these plans.

Nevertheless, the Cybertruck fits in Tesla’s future plans. Musk said the pickup will be needed for the transportation of local goods. Musk also said Cybertruck would be transitioned to an autonomous line.

SpaceX reportedly discussing merger with xAI ahead of blockbuster IPO

In a groundbreaking new report from Reuters, SpaceX is reportedly discussing merger possibilities with xAI ahead of the space exploration company’s plans to IPO later this year, in what would be a blockbuster move.

The outlet said it would combine rockets and Starlink satellites, as well as the X social media platform and AI project Grok under one roof. The report cites “a person briefed on the matter and two recent company filings seen by Reuters.”

Musk, nor SpaceX or xAI, have commented on the report, so, as of now, it is unconfirmed.

With that being said, the proposed merger would bring shares of xAI in exchange for shares of SpaceX. Both companies were registered in Nevada to expedite the transaction, according to the report.

Tesla announces massive investment into xAI

On January 21, both entities were registered in Nevada. The report continues:

“One of them, a limited liability company, lists SpaceX ​and Bret Johnsen, the company’s chief financial officer, as managing members, while the other lists Johnsen as the company’s only officer, the filings show.”

The source also stated that some xAI executives could be given the option to receive cash in lieu of SpaceX stock. No agreement has been reached, nothing has been signed, and the timing and structure, as well as other important details, have not been finalized.

SpaceX is valued at $800 billion and is the most valuable privately held company, while xAI is valued at $230 billion as of November. SpaceX could be going public later this year, as Musk has said as recently as December that the company would offer its stock publicly.

The plans could help move along plans for large-scale data centers in space, something Musk has discussed on several occasions over the past few months.

At the World Economic Forum last week, Musk said:

“It’s a no-brainer for building solar-powered AI data centers in space, because as I mentioned, it’s also very cold in space. The net effect is that the lowest cost place to put AI will be space and that will be true within two to three years, three at the latest.”

He also said on X that “the most important thing in the next 3-4 years is data centers in space.”

If the report is true and the two companies end up coming together, it would not be the first time Musk’s companies have ended up coming together. He used Tesla stock to purchase SolarCity back in 2016. Last year, X became part of xAI in a share swap.

Tesla hits major milestone with Full Self-Driving subscriptions

Tesla has announced it has hit a major milestone with Full Self-Driving subscriptions, shortly after it said it would exclusively offer the suite without the option to purchase it outright.

Tesla announced on Wednesday during its Q4 Earnings Call for 2025 that it had officially eclipsed the one million subscription mark for its Full Self-Driving suite. This represented a 38 percent increase year-over-year.

This is up from the roughly 800,000 active subscriptions it reported last year. The company has seen significant increases in FSD adoption over the past few years, as in 2021, it reported just 400,000. In 2022, it was up to 500,000 and, one year later, it had eclipsed 600,000.

In mid-January, CEO Elon Musk announced that the company would transition away from giving the option to purchase the Full Self-Driving suite outright, opting for the subscription program exclusively.

Musk said on X:

“Tesla will stop selling FSD after Feb 14. FSD will only be available as a monthly subscription thereafter.”

The move intends to streamline the Full Self-Driving purchase option, and gives Tesla more control over its revenue, and closes off the ability to buy it outright for a bargain when Musk has said its value could be close to $100,000 when it reaches full autonomy.

It also caters to Musk’s newest compensation package. One tranche requires Tesla to achieve 10 million active FSD subscriptions, and now that it has reached one million, it is already seeing some growth.

The strategy that Tesla will use to achieve this lofty goal is still under wraps. The most ideal solution would be to offer a less expensive version of the suite, which is not likely considering the company is increasing its capabilities, and it is becoming more robust.

Tesla is shifting FSD to a subscription-only model, confirms Elon Musk

Currently, Tesla’s FSD subscription price is $99 per month, but Musk said this price will increase, which seems counterintuitive to its goal of increasing the take rate. With that being said, it will be interesting to see what Tesla does to navigate growth while offering a robust FSD suite.
