Terraforming Mars may still be possible after NASA concludes otherwise, scientists say

Published

on

SpaceX’s Elon Musk may imagine a nuclear device acting as an artificial sun on Mars for his long-term terraforming plans, but NASA has ultimately disagreed with his and others’ proposals thus far for the planet. With this in mind, Harvard University scientists have conducted a study using silica aerogel to create regionally terraformed parts of the planet instead. Their results were recently published in Nature Astronomy.

NASA’s message is clear: The amount of carbon dioxide (CO2) that would be required to warm Mars enough to provide the required atmospheric pressure for human survival is not present on the red planet.

“Transforming the inhospitable Martian environment into a place astronauts could explore without life support is not possible without technology well beyond today’s capabilities,” NASA concluded in a press release last year on the topic of making our neighbor into the next Earth. “Our results suggest that there is not enough CO2 (carbon dioxide) remaining on Mars to provide significant greenhouse warming were the gas to be put into the atmosphere; in addition, most of the CO2 gas is not accessible and could not be readily mobilized. As a result, terraforming Mars is not possible using present-day technology.”

The Harvard scientists who published the recent study have instead proposed a way around this problem by exchanging a planet-wide terraforming strategy for a local one. By covering certain areas of the Martian surface with a thin layer of silica aerogel, namely areas with large amounts of water ice, enough sunlight will come through for warming and combine with natural heating processes beneath the surface to create a potentially habitable environment.

“Specifically, we demonstrate via experiments and modelling that under Martian environmental conditions, a 2–3 cm-thick layer of silica aerogel will simultaneously transmit sufficient visible light for photosynthesis, block hazardous ultraviolet radiation and raise temperatures underneath it permanently to above the melting point of water, without the need for any internal heat source,” the study’s abstract detailed.

Once temperatures were adequate, the gases released from the ice in the lakes and regolith (soil) would build up to form a pressurized atmosphere under the aerogel layer. If successful up to that point, microbes and plant life could theoretically survive. “Placing silica aerogel shields over sufficiently ice-rich regions of the Martian surface could therefore allow photosynthetic life to survive there with minimal subsequent intervention,” the scientists suggested. This photosynthetic life would go on to produce oxygen for pickier Earth dwellers to utilize.

In addition to proposing the utilization of silica aerogel’s heat trapping properties, the research team also conducted tests using environmental factors that mimicked those on Mars. Their results thus far indicate that warming beyond the required temperature for liquid water would be readily available to implement as needed under the aerogel. These results are promising, but many more tests and in-situ research will also be necessary to prove the concept further.

While NASA’s findings published last year seem to dash SpaceX’s dream of eventually terraforming Mars (for the full picture, see their transforming coffee mug), this latest effort demonstrates that all options are not yet off the table. Perhaps if the Harvard team’s further studies and tests positively demonstrate the potential of their silica aerogel habitat idea, small regions throughout the planet could resemble Earth’s most ideal places – very similar to Earth itself.

Would these areas be akin to bubble cities and bubble parks? Would the aerogel cover geodesic structures, as is seen in many other Martian colony concepts? Even if all the answers aren’t in yet, the enthusiasm for finding answers is exciting.

Tesla launches its new branded Supercharger for Business with first active station

Published

Tesla has officially launched its first branded Supercharger just months after initiating a new program that allows third-party companies to brand their own charging piles.

The site opened in Land O’ Lakes, Florida, and features eight V4 Supercharging stalls offering up to 325 kW of charging speed. It appears it was purchased by a company called Suncoast Credit Union. This particular branch is located Northeast of Tampa, which is on the Gulf of Mexico.

It features graphics of Florida animals, like alligators:

Tesla launched this program back in September, and it basically was a way to expand its Supercharger presence and also allow companies to pay for the infrastructure. Tesla maintains it. When it announced the “Supercharger for Business,” it said:

“Purchase and install Superchargers at your business. Superchargers are compatible with all electric vehicles, bringing EV drivers to your business by offering convenient, reliable charging.”

The program does a few things. Initially, it expands EV charging infrastructure and makes charging solutions more readily available for drivers. It can also attract people to those businesses specifically.

The chargers can also be branded with any logo that the business chooses, which makes them more personalized and also acts as an advertisement.

The best part is that the customers do not have to maintain anything about the Supercharger. Tesla still takes care of it and resolves any issues:

“We treat your site like we treat our sites. By providing you with a full-service package that includes network operations, preventative maintenance, and driver support, we’re able to guarantee 97% uptime–the highest in the industry.”

It appears the Superchargers will also appear within the in-car nav during routing, so they’ll be publicly available to anyone who needs to use them. They are still available to all EVs that have worked with Tesla to utilize its infrastructure, and they are not restricted to people who are only visiting the business.

Tesla reveals its Cybertruck light bar installation fix

Tesla has revealed its Cybertruck light bar installation fix after a recall exposed a serious issue with the accessory.

Tesla and the National Highway Traffic Safety Administration (NHTSA) initiated a recall of 6,197 Cybertrucks back in October to resolve an issue with the Cybertruck light bar accessory. It was an issue with the adhesive that was provided by a Romanian company called Hella Romania S.R.L.

Tesla recalls 6,197 Cybertrucks for light bar adhesive issue

The issue was with the primer quality, as the recall report from the NHTSA had stated the light bar had “inadvertently attached to the windshield using the incorrect surface primer.”

Instead of trying to adhere the light bar to the Cybertruck with an adhesive, Tesla is now going to attach it with a bracketing system, which will physically mount it to the vehicle instead of relying on adhesive strips or glue.

Tesla outlines this in its new Service Bulletin, labeled SB-25-90-001, (spotted by Not a Tesla App) where it shows the light bar will be remounted more securely:

The entire process will take a few hours, but it can be completed by the Mobile Service techs, so if you have a Cybertruck that needs a light bar adjustment, it can be done without taking the vehicle to the Service Center for repair.

However, the repair will only happen if there is no delamination or damage present; then Tesla could “retrofit the service-installed optional off-road light bar accessory with a positive mechanical attachment.”

The company said it would repair the light bar at no charge to customers. The light bar issue was one that did not result in any accidents or injuries, according to the NHTSA’s report.

This was the third recall on Cybertruck this year, as one was highlighted in March for exterior trim panels detaching during operation. Another had to do with front parking lights being too bright, which was fixed with an Over-the-Air update last month.

Tesla is already expanding its Rental program aggressively

The program has already launched in a handful of locations, specifically, it has been confined to California for now. However, it does not seem like Tesla has any interest in keeping it restricted to the Golden State.

Tesla is looking to expand its Rental Program aggressively, just weeks after the program was first spotted on its Careers website.

Earlier this month, we reported on Tesla’s intention to launch a crazy new Rental program with cheap daily rates, which would give people in various locations the opportunity to borrow a vehicle in the company’s lineup with some outrageous perks.

Along with the cheap rates that start at about $60 per day, Tesla also provides free Full Self-Driving operation and free Supercharging for the duration of the rental. There are also no limits on mileage or charging, but the terms do not allow the renter to leave the state from which they are renting.

The program has already launched in a handful of locations, specifically, it has been confined to California for now. However, it does not seem like Tesla has any interest in keeping it restricted to the Golden State.

Job postings from Tesla now show it is planning to launch the Rental program in at least three new states: Texas, Tennessee, and Massachusetts.

The jobs specifically are listed as a Rental Readiness Specialist, which lists the following job description:

“The Tesla Rental Program is looking for a Rental Readiness Specialist to work on one of the most progressive vehicle brands in the world. The Rental Readiness Specialist is a key contributor to the Tesla experience by coordinating the receipt of incoming new and used vehicle inventory. This position is responsible for fleet/lot management, movement of vehicles, vehicle readiness, rental invoicing, and customer hand-off. Candidates must have a high level of accountability, and personal satisfaction in doing a great job.”

It also says that those who take the position will have to charge and clean the cars, work with clients on scheduling pickups and drop-offs, and prepare the paperwork necessary to initiate the rental.

The establishment of a Rental program is big for Tesla because it not only gives people the opportunity to experience the vehicles, but it is also a new way to rent a car.

Just as the Tesla purchasing process is more streamlined and more efficient than the traditional car-buying experience, it seems this could be less painful and a new way to borrow a car for a trip instead of using your own.
