NASA’s Mars Curiosity rover recently detected a high amount of methane in the planet’s surface air, a gas that’s often found as a byproduct of microbes. The team behind the mission is now running follow-up experiments over the weekend, the results of which are expected by Monday, according to an internal email obtained by The New York Times. Scientists working on other Mars missions, to include the Mars Express and ExoMars Trace Gas Orbiters, are also working with Curiosity’s team to verify the data and determine what the broader implications could mean.

The discovery of significant amounts of methane on the Martian surface may indicate recent life on the planet due to the way the gas interacts with sunlight and other chemicals, as also noted in the Times’ report. Any methane produced would only survive a few centuries, so amounts measurable today point to more recent emissions, or more specifically, ‘recent’ in terms of the huge time frames involved in planetary evolution.

Spikes in methane gas have been detected on Mars before, but the current readings demonstrate some of the highest levels indicated. Specifically, 21 methane parts per billion (ppb) were detected this week by Curiosity verses the 7 ppb detected in a 2013 spike and 1 ppb detected when the rover initially arrived on the red planet. The highest reading thus far was found in 2009 at 45 ppb using the NASA Infrared Telescope Facility and the telescopes at the W.M. Keck Observatory in Hawaii.

The presence of methane on Mars has been a bit of a mystery as readings dedicated to the gas have varied in major ways. While telescopes and rovers have indicated its presence on the planet numerous times, results from the European Space Agency’s ExoMars Trace Gas Orbiter in December last year showed no sign of methane even down to 50 parts per trillion. This in itself could also be a positive indicator, though, albeit initially confusing. Variations in surface-level readings that stand in contrast to orbit-based atmospheric readings could be evidence that the methane is coming from the ground rather than space-faring visitors like comets.

Other theories that would explain the presence of methane without current biological life include geological processes. Cold Martian temperatures could mean that methane produced much earlier in the planet’s timeline was simply trapped in ice and is being released periodically by geological activity. Data analysis by Curiosity’s team earlier this year found a seasonal cycle of methane release near Mars’s Gale Crater which is full of ice and thought to be a dried lake bed.

Regardless of the source, the detection of methane on Mars indicates some sort of geological or biological activity. Earth itself is full of life in the most interesting places, to include inside very deep layers of ocean sediment, and we can likely look forward to exciting discoveries from our red neighbor no matter what’s ultimately determined about its methane source.

Elon Musk

Tesla Phone? Not quite, but close: analyst

For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.

It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.

Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.

The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.

Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.

The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.

SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.

There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.

The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.

Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.

The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.

On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.

It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:

“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.

It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something

There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.

Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.

Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.

Here are the full release notes for the suite:

  • Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
  • Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
  • Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
  • Introduced parking, unparking, and reversing capabilities.
  • Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
  • Speed Profiles are now available at all times, to further customize driving style preference.

These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.

He added:

“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”

Tesla will continue to roll out the v14 Lite suite more widely in the coming weeks, the company said.
