NASA finds more hints of life on Mars in latest Curiosity Rover discovery
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.

Texas lawmakers urge Tesla to delay Austin robotaxi launch to September
The letter urges Tesla to delay its initial robotaxi launch in the interest of public safety.

A group of Democratic lawmakers from Austin is asking Tesla to postpone its planned robotaxi rollout, at least until a new state law governing autonomous vehicles takes effect in September.
The letter, which was sent Wednesday, urges Tesla to delay its initial robotaxi launch in the interest of public safety.
What the lawmakers’ letter says
In their letter, the Democratic lawmakers stated that delaying Tesla’s initial robotaxi launch would build trust in the electric vehicle maker’s autonomous vehicle operations.
“We are formally requesting that Tesla delay autonomous robotaxi operations until the new law takes effect on September 1, 2025. We believe this is in the best interest of both public safety and building public trust in Tesla’s operations,” the letter read.
The lawmakers noted that if Tesla wishes to push through with its planned June 22 launch, the company must provide detailed information explaining its robotaxi service’s initial launch.
New rules kick in September
The new Texas law passed state legislature last month, and it introduces stricter requirements for companies deploying fully self-driving cars.
Current state law allows autonomous vehicle testing without a human driver, as long as vehicles meet basic registration and insurance standards. The updated framework gives state agencies more oversight, including the ability to revoke permits if autonomous vehicles pose safety risks.
It remains to be seen if the Democratic lawmakers’ efforts will bear fruit, especially since Texas is state where Republicans hold the governorship and majorities in both legislative chambers, as noted in a Reuters report.
Elon Musk, for his part, confirmed that Tesla’s initial robotaxi launch for Austin this June will start with a small fleet of Model Y vehicles. He also noted the service would initially operate only in parts of the city the company deems safest.
Tesla has not issued a comment about the Democratic lawmakers’ letter as of writing.

xAI’s Grok 3 partners with Oracle Cloud for corporate AI innovation
Elon Musk’s xAI partners with Oracle to deliver Grok 3 to enterprise users via OCI. The move boosts Grok’s reach.

xAI’s Grok 3 is partnering with Oracle Cloud to deliver its advanced AI model to corporate customers.
Oracle announced its collaboration with xAI earlier this week. The partnership leverages Oracle’s robust infrastructure to offer xAI’s Grok 3, positioning it as a transformative tool for business applications.
“Today, we announced xAI has selected Oracle to offer xAI’s Grok models via OCI Generative AI service for a wide range of use cases and will use OCI’s leading AI infrastructure to train and run inferencing for its next-generation Grok models,” said Clay Magouyrk, Executive Vice President at Oracle Cloud Infrastructure, via LinkedIn.
Oracle’s cost-effective AI capabilities will support xAI’s demanding workloads, enabling faster processing for enterprise users.
Oracle’s Karan Batta told Reuters: “Our goal here is to make sure that we can provide a portfolio of models – we don’t have our own.” Oracle will host Grok 3 alongside models from Meta, Mistral, and Cohere, ensuring corporate data remains secure within existing Oracle protections.
Oracle’s strategy focuses on integrating popular AI models into corporate software, and xAI’s Grok 3 enhances this portfolio. The collaboration expands Grok’s reach to businesses seeking secure, high-performance AI solutions for diverse use cases.
Elon Musk’s xAI launched Grok 3 in February. It competes with models from DeepSeek and OpenAI. Grok 3 is free for all X users, but features are limited. X offers Premium and Premium+ subscribers access to Grok 3’s advanced capabilities like DeepResearch and Think modes. Users who are not paid subscribers have access to Grok 3’s basic features.
Elon Musk’s companies have a longstanding relationship with Oracle. In 2018, Tesla appointed Oracle founder Larry Ellison to its board, a move Wedbush analyst Daniel Ives called a “home run appointment.”
In 2023, Ellison–who is no longer on Tesla’s board but still close with Musk–revealed plans for a Tesla Cybertruck police car.
“Our next-generation police car is coming out very soon,” Ellison said at the 2023 Oracle CloudWorld conference in Las Vegas. “It’s my favorite police car. It’s my favorite car, actually. It’s Elon’s favorite car.”
Grok 3’s integration into Oracle Cloud strengthens xAI’s position in the corporate artificial intelligence market. By combining Oracle’s infrastructure with Grok’s cutting-edge capabilities, this collaboration could redefine enterprise AI adoption, driving innovation across industries.

Tesla Robotaxis are becoming a common sight on Austin’s public roads
Tesla Robotaxi sightings are becoming much more frequent ahead of its launch planned for this month.

Tesla Robotaxis are becoming a common sight on the public roads of Austin, Texas, as yet another test mule has been spotted near the company’s target launch date.
Just over a week ago, the first public sighting of a driverless Tesla Robotaxi was reported. The vehicle was an updated version of the Tesla Model Y, which will be the initial model used in the public deployment of the Robotaxi platform.
Throughout the past week, sightings have been more common, as people in Austin have been looking for the unique decal Tesla is placing on car doors to recognize the driverless vehicles (After all, Robotaxis are not as easy to recognize as driverless vehicles without the LIDAR unit on the roof like Waymo).
Yet another sighting of a Robotaxi was shared on social media today, just two days before CEO Elon Musk’s proposed launch date of June 22:
🚨 Tesla Robotaxis are being spotted all over Austin!
Here’s another spotted within the last hour: https://t.co/79l1RHpL5d pic.twitter.com/bOIlZYgs0U

It is easy to tell that there is nobody in the driver’s seat of this vehicle. Tesla is using its white interior on this particular mule, making it incredibly simple to recognize that no human is controlling the car.
Whether Tesla will still meet the June 22nd deadline remains to be seen, but it is no secret that the company is prioritizing safety ahead of offering public rides.
Tesla will initially roll out the Robotaxi platform in Austin, but it has already started the regulatory process in other areas, specifically California.
The National Highway Traffic Safety Administration (NHTSA) is also helping to streamline the process for companies developing driverless vehicles by giving exemptions to automakers. It will make things much more efficient, benefiting Tesla and other car companies that have similar plans.
Tesla Robotaxi just got a big benefit from the U.S. government
