Mars rover to Earth, this red planet has a methane problem
NASA’s Curiosity rover has been exploring an area of Mars called Gale Crater, since landing on the red planet in 2012. It was tasked with assessing the habitability of Mars. What was Mars like in the past? Were the conditions right for life?
Let’s be clear, Curiosity was not equipped with the instruments needed to identify life forms, but it can tell us if conditions were right for life to have survived.
Throughout its time on the red planet, Curiosity has discovered a bit of an enigma: Mars has methane and the abundance changes with the seasons. Big surges of methane can indicate that some sort of biological process is taking place, but that’s not always the case. And it’s not a definitive sign of life.
Methane is a gas produced by one of two methods on Earth: biological and geological. That means that some sort of life form could be producing or perhaps there’s some sort of geological explanation.
This is puzzling to scientists back on Earth because the Martian methane has been detected by ground-based telescopes. But recent orbital data from Mars shows the minuscule amounts of methane are gone.
In fact, the Trace Gas Orbiter (TGO)—a joint European and Russian mission—which launched in 2016 and was designed to sniff-out trace gases, such as methane, says the Martian air is basically methane-free.
But, NASA’s Curiosity rover may have just taken a big step forward in understanding this conundrum.
Curiosity’s detection of methane is nothing new. The six-wheeled rover has detected surges in methane throughout its mission. The most recent occurrence, recorded in June 2019, showed staggeringly high levels of methane—21 ppb (parts per billion). That’s the highest the rover has recorded to date.
Neither TGO nor its counterpart, the Mars Express orbiter, detected any methane at all in June.
TGO has detected minute amounts of methane—around 0.012 ppb—during its first few months of science operations. That’s equivalent to roughly 30 times less than what Curiosity sees. (Mars Express did detect the first methane surge that Curiosity spotted in June 2013.)
Why is there such a discrepancy between ground measurements and orbital data? The Curiosity science team has a few ideas.
First off, there could be some sort of atmospheric process taking place that is scrubbing it out of the atmosphere. Curiosity takes measurements on the ground and detects the methane, while TGO orbits the planet and does not. This means that something happens to it as it travels upwards through the atmosphere.
Another explanation could be atmospheric expansion and contraction. Mars has an atmosphere, albeit an incredibly thin one compared to Earth’s. Every day the heat from the sun causes the atmosphere to expand and contract.
As the atmosphere expands during the day, the methane could become more diffuse. Since Curiosity measure methane at night, when the rover is less busy, it could explain why the methane appears more abundant. That means that the rover is sniffing the atmosphere when its more dense, which means the methane concentration would be greater.
The team plans to take some daytime methane measurements and compare those with orbital data. This will give the team some insights into why the data is so different. Once they have that puzzle solved, they can move onto larger questions, like what generates the methane?
It’s also entirely possible that the gas may have been generated billions of years ago in deep, underground pockets, and it’s just now seeping up through the bedrock. Only time and more measurements can tell.
NASA is sending its next-generation Mars rover to the red planet this July. Dubbed the Mars 2020 rover, the vehicle is a souped-up version of Curiosity. This rover will not only be able to look for biosignatures (or signs of life), it will also bag up samples for a future return to Earth.

SpaceX secures FAA approval for 44 annual Starship launches in Florida
The FAA’s environmental review covers up to 44 launches annually, along with 44 Super Heavy booster landings and 44 upper-stage landings.
SpaceX has received environmental approval from the Federal Aviation Administration (FAA) to conduct up to 44 Starship-Super Heavy launches per year from Kennedy Space Center Launch Complex 39A in Florida.
The decision allows the company to proceed with plans tied to its next-generation launch system and future satellite deployments.
The FAA’s environmental review covers up to 44 launches annually, along with 44 Super Heavy booster landings and 44 upper-stage landings. The approval concludes the agency’s public comment period and outlines required mitigation measures related to noise, emissions, wildlife, and airspace management.
Construction of Starship infrastructure at Launch Complex 39A is nearing completion. The site, previously used for Apollo and space shuttle missions, is transitioning to support Starship operations, as noted in a Florida Today report.
If fully deployed across Kennedy Space Center and nearby Cape Canaveral Space Force Station, Starship activity on the Space Coast could exceed 120 launches annually, excluding tests. Separately, the U.S. Air Force has authorized repurposing Space Launch Complex 37 for potential additional Starship activity, pending further FAA airspace analysis.
The approval supports SpaceX’s long-term strategy, which includes deploying a large constellation of satellites intended to power space-based artificial intelligence data infrastructure. The company has previously indicated that expanded Starship capacity will be central to that effort.
The FAA review identified likely impacts from increased noise, nitrogen oxide emissions, and temporary airspace closures. Commercial flights may experience periodic delays during launch windows. The agency, however, determined these effects would be intermittent and manageable through scheduling, public notification, and worker safety protocols.
Wildlife protections are required under the approval, Florida Today noted. These include lighting controls to protect sea turtles, seasonal monitoring of scrub jays and beach mice, and restrictions on offshore landings to avoid coral reefs and right whale critical habitat. Recovery vessels must also carry trained observers to prevent collisions with protected marine species.

Texas township wants The Boring Company to build it a Loop system
The township’s board unanimously approved an application to The Boring Company’s “Tunnel Vision Challenge.”
The Woodlands Township, Texas, has formally entered The Boring Company’s tunneling sweepstakes.
The township’s board unanimously approved an application to The Boring Company’s “Tunnel Vision Challenge,” which offers up to one mile of tunnel construction at no cost to a selected community.
The Woodlands’ proposal, dubbed “The Current,” features two parallel 12-foot-diameter tunnels beneath the Town Center corridor near The Waterway. Teslas would shuttle passengers between Waterway Square, Cynthia Woods Mitchell Pavilion, Town Green Park and nearby hotels during concerts and large-scale events, as noted in a Chron report.
Township officials framed the tunnel as a solution for the township’s traffic congestion issues. The Pavilion alone hosts more than 60 shows each year and can accommodate crowds of up to 16,500, often straining Lake Robbins Drive and surrounding intersections.
“We know we have traffic impacts and pedestrian movement challenges, especially in the Town Center area,” Chris Nunes, chief operating officer of The Woodlands Township, stated during the meeting.
“The Current” mirrors the Loop system operating beneath the Las Vegas Convention Center, where Tesla vehicles transport passengers through underground tunnels between venues and resorts.
The Boring Company issued its request for proposals (RFP) in mid-January, inviting cities and districts to pitch local uses for its tunneling technology. The Woodlands must submit its application by Feb. 23, though no timeline has been provided for when a winning community will be announced.
Nunes confirmed that the board has authorized a submission for “The Current’s” proposal, though he emphasized that the project is still in its preliminary stages.
“The Woodlands Township Board of Directors has authorized staff to submit an application to The Boring Company, which has issued an RFP for communities interested in leveraging their technology to address community challenges,” he said in a statement.
“The Board believes that an underground tunnel would provide a safe and efficient means to transport people to and from various high-use community amenities in our Town Center.”

Tesla Model Y wins 2026 Drive Car of the Year award in Australia
The Model Y is already Australia’s best-selling EV in 2025 and the tenth best-selling vehicle overall.
The Tesla Model Y has been named 2026 Drive Car of the Year overall winner, taking the top honor after being judged as the vehicle that “moves the game forward the most for Australian new car buyers.”
The Model Y is already Australia’s best-selling EV in 2025 and the tenth best-selling vehicle overall, but the vehicle’s Juniper update strengthened its case with new ownership benefits and expanded software capability.
Drive’s overall award compares category winners and looks at which model most significantly advances the local new car market. In 2026, judges pointed to the Model Y’s five-year warranty and the availability of Full Self-Driving (Supervised) as a monthly subscription as key differentiators.
Priced from AU$58,900 before on-road costs, the all-electric crossover SUV offers a lot of value compared to similarly sized petrol and hybrid rivals. The ability to access Tesla’s Supercharger network across Australia also reduces friction for buyers moving to EV ownership.
Owners can add FSD (Supervised) for AU$149 per month. While it still requires driver oversight, the system expands the vehicle’s advanced driver-assistance capabilities and reflects Tesla’s software-first approach.
“The default choice for a reason. The Tesla Model Y makes the transition to electric both effortless and rewarding,” Drive wrote.
The 2025 Model Y facelift also sharpened the vehicle’s exterior, highlighted by a distinctive rear light bar that gives the crossover SUV a more modern road presence.
Drive described the Model Y as a benchmark for combining practicality, efficiency and technology at an accessible price point. With eligibility for federal Fringe Benefit Tax exemptions through novated leasing, its value proposition has improved for numerous buyers.
For 2026, the Model Y’s combination of range efficiency, charging access and software capability proved decisive. Ultimately, the award all but cements the Model Y’s position as one of the most influential vehicles in Australia’s evolving new-car market today.
