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)?

Tesla talks Semi ramp, Optimus, Robotaxi rollout, FSD with Wall Street firm

Published

Tesla (NASDAQ: TSLA) recently talked about a variety of topics with Wall Street firm Piper Sandler, as the firm released a new note on Friday about their meeting with the company’s Investor Relations team.

According to the note from Piper Sandler, Tesla talked in detail about the Semi program, Optimus, and its potential valuation given its capabilities, the rollout of Robotaxi in Austin, and Full Self-Driving progress in the United States.

Tesla Semi Ramp

The Tesla Semi is set to enter mass production in 2026 at a dedicated factory near the company’s Gigafactory in Reno, Nevada.

The Semi has already been in pilot program testing, as Tesla has partnered with a few companies, like Frito-Lay and PepsiCo., to perform regional logistics. It has been met with excellent reviews from drivers, and it has helped give Tesla a good idea of what to expect when it makes its way to more companies in the coming years.

Piper Sandler said that it is evident Tesla is preparing for a “major ramp,” but it is keeping its expectations low:

“We’ve never expected much from this product, but we’d love to be proven wrong (Tesla is clearly prepping for a major ramp).”

Tesla Optimus and its value internally and externally

Optimus has been working in Tesla factories for some time, but its expectations as a product offering outside of the company internally have major implications.

Its role within Tesla factories, for now, is relatively low, but Optimus is still doing things to assist. By this time next year, Piper Sandler said Optimus should have bigger responsibilities:

“By this time in 2026, Optimus should be moving/staging parts within Tesla’s facilities.”

Outside of Tesla, Optimus could be a major beneficiary for companies as it could be a more affordable way to handle tedious tasks and manual labor. The firm believes that if Optimus can work 18-hour shifts, a cost of $100,000 per unit “would be justified.”

Tesla Robotaxi Expansion

The big focus of the firm with Robotaxi was Tesla’s expansion of the geofence in Austin this week. It was substantial, bringing the Robotaxi’s total service area to around 170 square miles, up from the roughly 90 square miles that rival Waymo is offering in the city.

Tesla has doubled its geofence three times since its launch in late June, and it also revealed that its fleet of vehicles has expanded by 50 percent. It did not give a solid number of how many vehicles are operating in the fleet.

Tesla Full Self-Driving v14 launch

Tesla’s Full Self-Driving suite is set to have a fresh version, v14, rolled out in either September or October, and there are some pretty high expectations for it.

CEO Elon Musk said:

“The FSD release in about 6 weeks will be a dramatic gain with a 10X higher parameter count and many other improvements. It’s going through training & testing now. Once we confirm real-world safety of FSD 14, which we think will be amazing, the car will nag you much less.”

There is also some expectation that v14 could be the public release of what Tesla is running in Austin for Robotaxi. The firm confirmed this in their note by stating it “should enable Tesla owners to use software that is on par with Robotaxis in Austin.”

The only real hold up would be regulator skepticism, but Tesla can alleviate this with strong data.

The firm maintained its ‘Overweight’ rating and the $400 price target it holds on the stock.

Tesla starts Full Self-Driving rollout to owners in Australia

“To have this car drive me around Brisbane for an hour, we’re talking in the city, motorway, spaghetti bowl of on-ramps, it handled it so well. It was mind-blowing.”

Tesla has already started rolling out its Full Self-Driving suite to owners in Australia after officially launching the driver assistance suite in the country yesterday.

Earlier this week, Tesla seemed to be moving toward the launch of Full Self-Driving (Supervised) in Australia after numerous media members received early access to test its performance.

Tesla officially launched Full Self-Driving (Supervised) in Australia yesterday. The company told media members who got early access to the suite that the rollout would begin with Hardware 4-equipped Model 3 and Model Y vehicles.

The release would be slow and gradual, with the process performed in stages.

The first stage of the rollout has already begun in Australia:

Tesla is reminding drivers in Australia who are using the suite for the first time that they must not become complacent while FSD is in operation. It is not fully autonomous and still requires the driver to remain attentive to road conditions and the vehicle’s surroundings.

Currently, the suite is only available to purchase outright, and it comes at a cost of $10,100. A subscription model is in the works, similar to the one in the United States, but Tesla has not yet announced its plans or pricing model for this.

Australia is the sixth country to receive Full Self-Driving (Supervised), or at least some version of it, as the United States, Canada, Mexico, China, and Puerto Rico all have access to the suite currently. In China, it is slightly different and is referred to as “City Autopilot” due to regulatory boundaries.

Early reviews of the suite have been very strong, as local media have also had the opportunity to try it, with one journalist saying, To have this car drive me around Brisbane for an hour, we’re talking in the city, motorway, spaghetti bowl of on-ramps, it handled it so well. It was mind-blowing.”

Tesla expands crazy new lease deal for insane savings on used inventory

Tesla was able to work through the hurdles in three states, expanding the deal to New York, New Jersey, and Florida.

Tesla has expanded its new lease deal, offering people insane savings on used inventory.

Last week, we reported on Tesla offering crazy good lease deals on some of its used inventory, as people were able to grab monthly payments for as little as $225 per month with no money down.

There was only one catch: the deal was only available in California and Texas.

However, Tesla has been working hard to get the lease deal expanded, and it finally has. Last night, Tesla’s VP of Finance, Sendil Palani, confirmed the deal had made it to three additional states.

Palani explained that the deal was only available in California and Texas because the leasing process requires working through regulatory hurdles in each state. He said it “involves a nontrivial amount of work,” which makes things more difficult to iron out.

Tesla was able to work through the hurdles in three states, expanding the deal to New York, New Jersey, and Florida. It is currently active in those states, Palani said:

Tesla is really making a concerted effort to push its inventory out the door, and many areas already are running low on both new and pre-owned inventory. It has cut prices on some new inventory, while offering these new lease deals on used vehicles that remain.

It is beneficial to the consumer for obvious reasons: cheaper payments and the ability to get a great deal on a car for no money down. Tesla is also getting rid of vehicles that were once thought to be intended for the Robotaxi fleet, but it appears these older hardware vehicles are no longer in the company’s plans for that purpose.

This is the first time Tesla has offered lease deals on used inventory, as it has only offered an outright purchase option in the past. In an effort to boost deliveries and rid itself of older cars, these lease deals are truly beneficial for both parties. It is only a wonder how long they will last.
