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!

Elon Musk reveals when SpaceX will perform first-ever Starship catch

“Starship catch is probably flight 13 to 15, depending on how well V3 flights go,” Musk said.

Elon Musk revealed when SpaceX would perform the first-ever catch attempt of Starship, its massive rocket that will one day take life to other planets.

On Tuesday, Starship aced its tenth test flight as SpaceX was able to complete each of its mission objectives, including a splashdown of the Super Heavy Booster in the Gulf, the deployment of eight Starlink simulators, and another splashdown of the ship in the Indian Ocean.

It was the first launch that featured a payload deployment:

SpaceX Starship Flight 10 was so successful, it’s breaking the anti-Musk narrative

SpaceX was transparent that it would not attempt to catch the Super Heavy Booster, something it has done on three previous occasions: Flight 5 on October 13, 2024, Flight 7 on January 16, and Flight 8 on March 6.

This time, it was not attempting to do so. However, there are bigger plans for the future, and Musk detailed them in a recent post on X, where he discussed SpaceX’s plans to catch Starship, which would be a monumental accomplishment.

Musk said the most likely opportunities for SpaceX to catch Starship itself would be Flight 13, Flight 14, and Flight 15, but it depends on “how well the V3 flights go.”

The Starship launched with Flight 10 was a V2, which is the same size as the subsequent V3 rocket but has a smaller payload-to-orbit rating and is less powerful in terms of initial thrust and booster thrust. Musk said there is only one more V2 rocket left to launch.

V3 will be the version flown through 2026, as V4, which will be the most capable Starship build SpaceX manufactures, is likely to be the first company ship to carry humans to space.

Musk said that SpaceX planned to “hopefully” attempt a catch of Starship in 2025. However, it appears that this will likely be pushed back to 2026 due to timing.

SpaceX will take Starship catch one step further very soon, Elon Musk confirms

SpaceX would need to launch the 11th and 12th test flights by the end of the year in order to get to Musk’s expected first catch attempt of Flight 13. It’s not unheard of, but the company will need to accelerate its launch rate as it has only had three test flights this year.

Tesla Robotaxi rival Waymo confirms massive fleet expansion in Bay Area

New data from the California Public Utilities Commission (CPUC) said Waymo had 1,429 vehicles operating in California, and 875 of them were “associated with a terminal in San Francisco,” according to The SF Examiner.

Tesla Robotaxi rival Waymo has confirmed that it has expanded its fleet of driverless ride-sharing vehicles in the Bay Area of California massively since its last public disclosure.

It is perhaps one of the most important metrics in the race for autonomous supremacy, along with overall service area. Tesla has seemed to focus on the latter, while expanding its fleet slowly to maintain safety.

Waymo, on the other hand, is bringing its fleet size across the country to significant levels. In March, it told The SF Examiner that there were over 300 Waymos in service in the San Francisco area, which was not a significant increase from the 250 vehicles on the road it reported in August 2023.

In May, the company said in a press release that it had more than 1,500 self-driving Waymos operating nationwide. More than 600 were in the San Francisco area.

However, new data from the California Public Utilities Commission (CPUC) said Waymo had 1,429 vehicles operating in California, and 875 of them were “associated with a terminal in San Francisco,” according to The SF Examiner.

CPUC data from March 2025 indicated that there were a total of 1,087 Waymo vehicles in California, with 762 located in San Francisco. Some were test vehicles, others were deployed to operate as ride-sharing vehicles.

The company’s August update also said that it deploys more than 2,000 commercial vehicles in the United States. That number was 1,500 in May. There are also roughly 400 in Phoenix and 500 in Los Angeles.

While Waymo has done a good job of expanding its fleet, it has also been able to expand its footprint in the various cities it is operating in.

Most recently, it grew its geofence in Austin, Texas, to 90 square miles. This outpaced Tesla for a short period before the company expanded its Robotaxi service area earlier this week to roughly 170 square miles.

Tesla has launched its Full Self-Driving suite in a new region, marking a significant step in the company’s progress to expand its driver assistance suite on a global scale.

It is also the first time Tesla has launched FSD in a right-hand-drive market.

Today, Tesla launched Full Self-Driving in Australia for purchase by car buyers for $10,100, according to Aussie automotive blog Man of Many, which tried out the suite earlier this week.

Previously, Basic and Enhanced Autopilot suites were available, but the FSD capability now adds Traffic Light and Stop Sign Control, along with all the features of the previous two Autopilot suites.

It is the first time Tesla has launched the suite by name in a region outside of North America. In China, Tesla has “City Autopilot,” as it was not permitted to use the Full Self-Driving label for regulatory reasons.

However, Tesla still lists Full Self-Driving (Supervised) as available in the U.S., Canada, China, Mexico, and Puerto Rico.

The company teased the launch of the suite in Australia earlier this week, and it appeared to have been released to select media members in the region earlier this week:

The rollout of Full Self-Driving in the Australian market will occur in stages, as Model 3 and Model Y vehicles with Hardware 4 will receive the first batch of FSD rollouts in the region.

TechAU also reported that “the initial deployment of FSDs in Australia will roll out to a select number of people outside the company, these people are being invited into Tesla’s Early Access Program.”

Additionally, the company reportedly said it is “very close” to unlocking FSD in customer cars:

Each new Tesla sold will also come with a 30-day free trial of the suite.

Australia is the sixth country to officially have Full Self-Driving available to them, following the United States, Canada, China, Mexico, and Puerto Rico.

Here’s the first look at the suite operating in Australia:
