Mars has competition from Venus after new study shows signs of life

Published

on

NASA and SpaceX are simultaneously planning their trips to Mars and the Moon, but a recent study published in Nature Astronomy has brought a different planet into the running for a new near-term exploration mission: Venus.

A team of scientists led by Dr. Jane Graeves of Cardiff University in the UK just announced the discovery of phosphine in the clouds of Venus. This rare molecule is made either industrially or as a byproduct of microbes that live in oxygen-free environments, meaning there’s serious evidence that life may exist on our sister planet.

“This was an experiment made out of pure curiosity, really,” Dr. Graeves detailed to the Royal Astronomical Society. “I thought we’d just be able to rule out extreme scenarios, like the clouds being stuffed full of organisms. When we got the first hints of phosphine in Venus’ spectrum, it was a shock!”

With NASA’s 2020 Mars Rover Perseverance on its way to do some astrobiological science on our red neighbor, this new finding on Venus looks to now have some high-level advocates for prioritized exploration.

“Life on Venus? The discovery of phosphine, a byproduct of anaerobic biology, is the most significant development yet in building the case for life off Earth,” NASA Administrator Jim Bridenstine tweeted about the news shortly after its publication. “About 10 years ago NASA discovered microbial life at 120,000ft in Earth’s upper atmosphere. It’s time to prioritize Venus.”

Planetary scientist Paul Byrne of North Carolina State University echoed this same sentiment in a quote published by The New York Times. “If this planet is active and is producing phosphine, and there is something that’s making it in the Venus atmosphere, then by God almighty, forget this Mars nonsense,” Byrne opined. “We need a lander, an orbiter, we need a program.”

Similar to thinking about Mars’ ancient past being filled with more Earth-like components such as water bodies (or perhaps not), Venus is thought to have been the home to lakes, rivers, and oceans before a runaway greenhouse effect made it into the hellish landscape it is today. This thinking has partly lead to speculation about the possibility of microbes migrating or developing in the clouds of the planet as ‘aerial’ life where temperatures are much more Earth-like, albeit very acidic. “Finding phosphine on Venus was an unexpected bonus! The discovery raises many questions, such as how any organisms could survive. On Earth, some microbes can cope with up to about 5% of acid in their environment – but the clouds of Venus are almost entirely made of acid,” commented team member Dr. Clara Sousa Silva of MIT.

For planetary science enthusiasts, of course, the idea of looking for life or even a new home for humans in the clouds of Venus isn’t new. Astrobiologist David Grinspoon, for one, has been advocating for the planet’s cause for quite some time. “Venus, this planet where I’ve been proposing for decades that there could be a biosphere in the clouds,” he exclaimed in a recent video chat about the discovery. “I mean, Venus is a place we do not associate with extraterrestrial life… It’s so hot, and so dry, the pressure’s so huge…we think life is gonna be anywhere but Venus. But interestingly if you go 30 miles up into the clouds, it’s rather comfortable in the sense that it’s sort of like room temperature [and pressure] in the room you’re in right now.”

The discovery of phosphine on Venus is also exciting for exoplanet hunting endeavors, i.e., looking for signs of life on planets outside our solar system. “It’s very exciting because phosphine is a gas that should not exist in an atmosphere like Venus’,” Grinspoon explained. “It stands out as an anomaly… Not only that, phosphine has been previously suggested as a very good biosignature that we might find on an exoplanet – a gas that’s made by life. It’s not easy to make in non-biological ways.”

A renewed call for Venusian exploration is already ready to be answered by a few scientists and groups, one notable example being startup launch provider Rocket Lab. As a rocket company focused on dedicated missions for small payloads, Rocket Lab stands as a ready and willing partner for any organization looking to gather more data from Venus directly. In fact, CEO Peter Beck already has plans in the works for the planet most symbolically synonymous with romance.

“I’m madly in love with Venus,” Beck said on August 5th this year during a live streamed company update. “I’m working very hard to put together a private mission to go to Venus in 2023… At the very least, I think it’s a needle-mover even for just a private mission to try and go do something interplanetary. That sends a message to the rest of the world that, ‘Hey, look — we can do these things privately.’”

Another notable mission that’s relevant to Beck and Rocket Lab’s goals for small payload missions to interplanetary destinations was the Mars Cube One companions of NASA’s InSight lander launched in 2018. After traveling the the red planet with the lander, the twin cube satellites were able to send back data and a photo of Mars to Earth. This proved that tiny affordable spacecraft could be used for some serious deep-space science. Perhaps one of the biggest discoveries in our solar system of late could be followed up by an itty bitty mission (respectively)?

Starlink Mini 2 arrives with one feature for true off-grid connectivity

Published

SpaceX officially launched the Starlink Mini 2 on November 10, delivering the first portable Starlink terminal designed around independent power.

Invitation-only preorders for select U.S. customers are priced at $999 plus tax, a figure that includes a full year of Roam Unlimited service valued at roughly $2,100. A refundable $100 deposit reserves the kit, with the balance due at shipment, expected to begin in mid-December. Broader availability is listed as coming soon.

The headline feature is the quick-swap 71 Wh battery. Clipped to the rear of the dish without tools, it delivers up to 4.5 hours of connectivity on a single charge.

The 490-gram pack includes its own USB-C port and LED indicators, so users can charge a spare separately and swap it in seconds while staying online. Starlink notes that the terminal can continue operating while the battery charges or run directly from a 60 W USB-C source. The retail box includes one battery, a 60 W USB-C charger, and a 3-meter cable.

Beyond power, the Mini 2 is thinner at 23.1 mm (versus 38.5 mm on the original Mini) while measuring 263 × 314 mm. With the battery and kickstand attached it weighs 1.6 kg.

Built-in Wi-Fi 6 expands coverage to up to 1,800 square feet, an IP67 rating protects against dust and water, and a standard 1/4-20 tripod thread plus physical power button round out the design. Field of view remains 110 degrees, and the unit retains support for mobile use.

For travelers, campers, and remote workers, the swappable battery removes the longstanding requirement for an external power bank or vehicle outlet that defined the first Mini. Spare packs sold separately further extend runtime, turning the compact terminal into a more self-contained solution.

While the bundled $999 invitation price sits well above the original Mini’s current $149 starting point, the included year of service and genuine untethered operation mark a clear step forward in portable satellite internet.

SpaceX’s $24B Starbase supercomputer plan slipped past a key roadblock

SpaceX wants a Starbase tax break for a $24 billion gas plant and supercomputer campus.

SpaceX is asking its own company town for a tax break on a $24 billion natural gas power plant and supercomputing facility at Starbase, Texas, and the land it picked sits just outside the reach of a data center moratorium that took effect in neighboring Brownsville last week.

A City of Starbase public hearing notice says SpaceX “proposes to construct, own, and operate a gas-fired power plant and super-compute facility” on roughly 444 acres between Boca Chica Boulevard and the Port of Brownsville. The $24 billion figure covers only the initial phases, and the notice leaves room for future expansions. The Starbase City Commission will consider a property tax abatement and a related economic development agreement at a 7 p.m. hearing on December 9. The notice does not disclose the size or length of the abatement, or how much computing capacity the site would hold.

The location has a history. Over the summer, SpaceX asked Brownsville to remove the tract from its city limits and offered $220 million for water and wastewater projects in return. Brownsville approved the move in August, and Starbase later annexed the land. Brownsville’s own 90-day pause on data center applications took effect last week, and had the tract stayed inside the city, the project likely would have needed a different home.

The power side is already in front of state regulators. SpaceX has applied to the Texas Commission on Environmental Quality for air permits covering 35 mobile gas turbines producing roughly 750 megawatts, according to Politico, which also noted that two of the three Starbase commissioners voting on the incentives are SpaceX executives.

Building its own plant lets SpaceX skip the Texas grid. Gov. Greg Abbott paused new data center grid connections in August pending an audit, but a facility that generates its own electricity does not need one. The air permit still has to clear the TCEQ, where Abbott also ordered a halt on data center permits.

The bigger test arrives in January. Governor-elect Gina Hinojosa, who unseated Abbott last week, has said she will block data center approvals until the legislature passes new protections, and she has already asked state officials to hold off on any sale of Boca Chica State Park to SpaceX until she is sworn in. Tesla and SpaceX shares both fell the day after the election, and Musk’s first reaction on X was “Data centers in space looking pretty appealing right now.”

That line points to Starmind, SpaceX’s orbital compute constellation. Musk has said terrestrial compute will be “peanuts compared to orbital compute” and expects monthly orbital deployments to pass ground deployments around the end of 2028, as Teslarati reported. Until then, SpaceX still needs gigawatts on the ground. It ended the third quarter with 1.7 GW of nameplate compute, is targeting 2.5 to 3 GW by the end of this year and wants at least 10 GW more in 2027. Its existing Colossus sites around Memphis already run on gas turbines and face a lawsuit from residents over emissions.

Local reaction is split. The South Texas Environmental Justice Network has announced a protest, citing air quality, water use and energy bills, while some Brownsville residents told the Tribune they welcome the jobs. SpaceX did not respond to the Tribune’s questions about the project.

Tesla extends Cybertruck production as Musk concedes ‘sentimentality’

Tesla CEO Elon Musk announced that the company will extend Cybertruck production slightly to handle its extensive order backlog.

On Wednesday, Musk announced that “In order to work through more of the Cybertruck order backlog, production will be extended through the end of summer 2027.”

Tesla has already attempted to simplify its last months of production for the Cybertruck by eliminating several trim levels and only offering the Cyberbeast, the most expensive trim that starts at $109,990. The other two trim levels, the Cybertruck All-Wheel-Drive and Premium All-Wheel-Drive have both been discontinued.

There has been plenty of backlash against Tesla’s decision to ax the Cybertruck, but the company’s forecast prioritizes Cybercab and autonomy. Factory space at Gigafactory Texas that is not necessary is now being set aside for the Cybercab as the company truly embraces its “transportation-as-a-service” model.

There is still a slim chance the Cybertruck survives. Last evening, Tesla upfitter Unplugged Performance offered to take the Cybertruck line off of Tesla’s hands and continue building it, along with a CyberSUV.

Nevertheless, Tesla seems to be ending the Cybertruck on its terms after what will be a three-and-a-half-year run. It still does not really feel quite real; I think many of us thought the Cybertruck would be around for years to come.

Musk added more detail, stating that while it was not the smartest move, “there must be some room in this world for sentimentality or what’s the point?”

Other EV pickups on the market have experienced a similar fate.

The Ford F-150 Lightning was axed by the Detroit company due to the continued losses the company took from sales. That truck was never profitable, and Ford is still taking a quarterly loss in its EV side. However, things are moving along as it has plans for a mass market EV pickup, which will likely gather some substantial demand if Ford can get it just right.

Perhaps another extension or even a total change of heart might come. Only Musk knows.
