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 announced today that it would expand its launch capabilities into a new U.S. state: Louisiana.
Today, SpaceX, in conjunction with the Louisiana Economic Development Office, said that it will establish a new launch facility, which it will call Starbase, Louisiana. It will be located near Vermilion Parish, supporting thousands of launches each year, at least eventually.
CEO Elon Musk commented by stating, “Starbase Louisiana will ultimately have over a dozen launch towers, enabling more than 30 Starship flights per day and making it the biggest launch site on Earth!”

The expansion is SpaceX’s latest move to push its launch cadence to be more frequent than ever. SpaceX said that Starbase, Louisiana, will be built to “support thousands of Starship flights a year,” with the first coming in 2029.
SpaceX announced the new facility in partnership with the Louisiana Economic Development Office as it will bring a major influx of jobs and investments into the area. Currently, it will produce more than 3,000 new jobs in Louisiana, and SpaceX plans to invest at least $100 billion into the entire facility, ensuring that many jobs are created as a result.
Environmental Responsibility
SpaceX acknowledges the impact launches could have on marshlands, local wildlife, and water sources. Here’s how the company plans to help with the issues in Vermilion Parish:
- Restoring the Shoreline: “In Vermilion Parish, the shoreline is eroding between 3.3 and 23 feet per year. We’re partnering with state and federal agencies to expand Louisiana’s Coastal Master Plan and Coastal Wetlands Planning, Protection and Restoration Act projects, including Gulf shoreline protection breakwaters designed to reduce wave energy and slow loss along the Gulf edge.”
- Rebuilding the Marshlands: “In working with the state, we’re planning thousands of acres of marsh creation using beneficial-use placement of dredged material and offshore sediment sources. Restoration will also include interior marsh bank stabilization and rebuilding marsh in remnant canals. These projects can reconnect fragmented wetlands, restore natural buffers against storms, and return habitat that has been lost to erosion and historic canalization.”
- Preserving Coastal Wildlife: “Pecan Island and nearby wetlands are high-value habitat for migratory waterfowl, shorebirds, wading birds, and other coastal wildlife. SpaceX is not developing the full footprint of the land and will preserve wetlands and wildlife habitat. At existing launch sites, waterfowl and other birds continue to use nearby habitat during operations. Working with wildlife agencies, landowners, and conservation groups, SpaceX will support monitoring and management so this habitat stays productive and hunting, fishing, birding, and other recreational activities that are part of this coast’s culture can continue.”
SpaceX shares rose about 2.5 percent on the news.
Tesla Cybertruck trims saw a big price change, at least on two of the three available to consumers, as demand for the all-electric pickup appears to be increasing.
Tesla bumped up its Base All-Wheel-Drive trim level up to $74,990 from $69,990 and the Premium All-Wheel-Drive configuration from $79,990 to $84,990. The Cyberbeast price remains unchanged at $99,990.
🚨 Cybertruck prices went up as Tesla bumped them 7%
– Tesla Cybertruck AWD is now $74,990
– Tesla Cybertruck Premium AWD now $84,990
– Tesla Cyberbeast now $99,990 https://t.co/MYJbaw56GL— TESLARATI (@Teslarati) August 25, 2026
Despite questions of demand for the truck, Tesla is bumping its two least expensive trims up $5,000 to signal that there are plenty of buyers. Although SpaceX has been buying Tesla Cybertruck units to utilize as company vehicles, it is no secret that the Cybertruck is among the most sought-after Tesla models out there.
The issue has always been pricing, at least for the most part. When Tesla initially launched the Cybertruck AWD at $59,990 a few months back, the company stated that price would remain intact for just ten days due to the influx of orders it received.
Cybertruck Sales: Is It the Product or Pricing?
Depending on who you ask, you will likely hear one of two explanations for relatively low Cybertruck sales: either the product itself or the pricing.
Yes, this is the best-selling all-electric pickup on the market. However, there are people who simply hate the look of it, which I understand, but do not agree with. Look is totally subjective, and I love the look of the Cybertruck.
Some people will not buy the Cybertruck because of the look, but I am under the impression that sales would be much better if this truck were priced lower; something that might not be possible considering Tesla’s need to make money on its products. When it was unveiled in 2019, its most expensive trim level was $69,990. Now, the cheapest trim level is more expensive than that.
I would be in a Cybertruck if it were more affordable. I LOVE my Model Y, but Cybertruck is the best vehicle Tesla makes, and it’s not particularly close. Even in the base model, the steer-by-wire, the space, storage, and performance make it more desirable than the Model Y to me. I cannot be the only Tesla owner without a Cybertruck who feels this way.

Tesla Semi factory is getting a celebration nobody expected
Tesla will inaugurate its Nevada Semi factory September 24, five months after production quietly began ramping.
Tesla says it will officially inaugurate its new Semi factory in Nevada next month. The Tesla Semi account posted the announcement on X, sharing a graphic titled “Semi Rollout” with a date of September 24. No further details were given about the format of the event or who would attend.
While Tesla’s dedicated Semi plant in Sparks, adjacent to Gigafactory Nevada, opened back in April, with the first trucks rolling off the high volume line on April 29, the timing for the factory inauguration comes at a surprise. The ribbon cutting event five months into production is a break from how Tesla has usually handled its other factories, where the first truck or car off the line typically served as the milestone moment.

The 1.7 million square foot factory was built as part of a $3.6 billion expansion Tesla announced in early 2023, and it shares a site with the battery cell lines that feed the Semi’s structural pack, a decision meant to remove the supply bottleneck that delayed the truck for years. The plant is designed for 50,000 trucks a year at full ramp. Semi program director Dan Priestley has said production “is now ramping” rather than claiming it has reached scale.
Nine years passed between the Semi’s 2017 unveiling and this stage of production, with the truck slipping from an original 2019 target through hand built pilot units for PepsiCo and a slow build out of the Nevada plant. An inauguration event now gives Tesla a stage to talk up that ramp and reset expectations for how many trucks it can begin delivering at scale.
The September date also lines up with the Semi’s next milestone. Tesla confirmed the truck is heading to Europe with a full unveiling at the IAA Transportation trade show in Hannover, Germany, running September 15 through 20. Between the Nevada event and the Hannover reveal, Tesla has roughly a week and a half in September to make the case that the Semi is now a truck being built and sold on two continents rather than tested in a handful of fleets.
