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.

Recent commentary on social media has highlighted what could very well prove to be The Boring Company’s real disruption.

The analysis was shared by tech watcher Aakash Gupta on social media platform X, where he argued that the real story behind the tunneling startup’s Nashville tunnel project is the company’s targeted $25 million per mile construction cost.

According to Gupta’s breakdown, Nashville’s 2018 light rail proposal was priced at roughly $200 million per mile. New York’s East Side Access project reportedly cost about $3.5 billion per mile, while Los Angeles Metro expansion projects have approached $1 billion per mile.

By comparison, The Boring Company has stated it can construct 13 miles of twin tunnels in the Music City Loop for between $240 million and $300 million total. That implies a cost near $25 million per mile, or roughly a 95% reduction from industry averages cited in the post.

Several technical departures from conventional tunneling allow the Boring Company to lower its costs, from its smaller 12-foot diameter tunnels to its fully electric Prufrock machines that are designed to mine continuously with no personnel inside the tunnel and their capability to “porpoise” for easy launch and retrieval.

Tesla and Space CEO Elon Musk responded to the post on X, stating simply that “Tunnels are so underrated.”

The Boring Company has seen some momentum as of late, with the company recently signing a construction contract in Dubai and the Universal Orlando Loop progressing. Recent reports have also pointed to tunnels potentially being constructed to solve traffic congestion issues near the Giga Nevada area. 

While The Boring Company’s tunnels have so far been used for Loop systems publicly for now, Elon Musk recently noted that the tunneling startup’s underground passages would not be limited only to ride-hailing vehicles.

In a reply to a post on X which discussed the specifications of the Music City Loop, Musk clarified that “any fully autonomous electric cars can use the tunnels.” This suggests that vehicles potentially running systems like FSD Supervised, even if they are not Teslas, could be used in systems like the Music City Loop in the future.

SpaceX IPO could push Elon Musk’s net worth past $1 trillion: Polymarket

The estimates were shared by the official Polymarket Money account on social media platform X.

Recent projections have outlined how a potential $1.75 trillion SpaceX IPO could generate historic returns for early investors. The projections suggest the offering would not only become the largest IPO in history but could also result in unprecedented windfalls for some of the company’s key investors.

The estimates were shared by the official Polymarket Money account on social media platform X.

As noted in a Polymarket Money analysis, Elon Musk invested $100 million into SpaceX in 2002 and currently owns approximately 42% of the company. At a $1.75 trillion valuation following SpaceX’s potential $1.75 trillion IPO, that stake would be worth roughly $735 billion.

Such a figure would dramatically expand Musk’s net worth. When combined with his holdings in Tesla Inc. and other ventures, a public debut at that level could position him as the world’s first trillionaire, depending on market conditions at the time of listing.

The Bloomberg Billionaires Index currently lists Elon Musk with a net worth of $666 billion, though a notable portion of this is tied to his TSLA stock. Tesla currently holds a market cap of $1.51 trillion, and Elon Musk’s currently holds about 13% to 15% of the company’s outstanding common stock.

Founders Fund, co-founded by Peter Thiel, invested $20 million in SpaceX in 2008. Polymarket Money estimates the firm owns between 1.5% and 3% of the private space company. At a $1.75 trillion valuation, that range would translate to approximately $26.25 billion to $52.5 billion in value.

That return would represent one of the most significant venture capital outcomes in modern Silicon Valley history, with a growth of 131,150% to 262,400%.

Alphabet Inc., Google’s parent company, invested $900 million into SpaceX in 2015 and is estimated to hold between 6% and 7% of the private space firm. At the projected IPO valuation, that stake could be worth between $105 billion and $122.5 billion. That’s a growth of 11,566% to 14,455%.

Other major backers highlighted in the post include Fidelity Investments, Baillie Gifford, Valor Equity Partners, Bank of America, and Andreessen Horowitz, each potentially sitting on multibillion-dollar gains.

Tesla has started its first Full Self-Driving (Supervised) road trials in Abu Dhabi under the oversight of the Integrated Transport Centre, also known as Abu Dhabi Mobility. 

The program marks the emirate’s first formal testing framework for Tesla’s supervised autonomous driving technology.

FSD (Supervised) road trials are being conducted with the support of the Smart and Autonomous Systems Council and in coordination with the Legislation Lab at the General Secretariat of the UAE Cabinet.

Dr. Abdulla Hamad AlGhfeli, Acting Director General of the Integrated Transport Centre (Abu Dhabi Mobility), highlighted the agency’s regulatory role in overseeing the FSD (Supervised) tests in a press release

“The supervision of the Integrated Transport Centre (Abu Dhabi Mobility) over the commencement of Tesla’s advanced autonomous driving technology tests reflects its regulatory and legislative role. These tests represent a qualitative step to evaluate the technology’s performance in a real-world operating environment and to collect the necessary data to verify its readiness before any future expansion in usage.

“Through this organized framework, and in cooperation with strategic partners, we seek to achieve a balance between supporting innovation and encouraging the adoption of smart solutions on one hand and ensuring the safety of road users on the other, in line with the emirate’s direction to develop an advanced, safe, and sustainable transport system,” he said. 

Tesla is putting a lot of effort into expanding the rollout of FSD (Supervised) to territories outside in the United States. During a recent interview with Giga Berlin plant manager Andre Thierig, Musk stated that Tesla is looking to secure approval for FSD (Supervised) in the Netherlands this coming March. 

“Tesla has the most advanced real-world AI, and hopefully, it will be approved soon in Europe. We’re told by the authorities that March 20th, it’ll be approved in the Netherlands,’ what I was told. Hopefully, that date remains the same. But I think people in Europe are going to be pretty blown away by how good the Tesla car AI is in being able to drive,” Musk stated.
