NASA and SpaceX probably can’t terraform Mars but that doesn’t matter

Published

on

In recent weeks, a great deal of exaggerative noise has been spread wide about the supposed impossibility of making the planet Mars more Earth-like and hospitable, a concept known as terraforming. The reality is quite a bit different, especially within the context of any SpaceX or NASA-driven human outposts or colonization attempts.

Triggered by comparatively reasonable research just published by two experienced planetary scientists, much of the hyperbolic media coverage that followed failed to properly frame the true challenges of terraforming the Red Planet.

The entire limb of Mars captured by ESA’s Mars Express orbiter, June 2017.

Keeping the cart behind the horse

Before anything else, it’s critical to take a step back from the idea of terraforming and consider the simpler facts of any human presence on Mars. First, the rationale for a permanent human presence on Mars is largely independent of the environmental conditions on the planet – it’s a huge help to have basic resources available in situ (on site), but the difficulty of surviving in a given non-Earth environment is immaterial to the human desire to both explore and survive.

Assuming we humans really do want to ensure that a subset of ourselves can independently survive any truly global catastrophe on Earth, be it natural or artificial, we will find a way to do so in even the harshest of environments. Living on Mars would be downright luxurious compared to life aboard the International Space Station, thanks largely to ~1/3rd Earth gravity, accessible natural resources to replenish consumables, an Earthlike day and night cycle, considerably more forgiving temperature extremes, and much more.

 

Despite the inhospitable conditions, human presence aboard the ISS has been uninterrupted for nearly 20 years, even though the average stay per crewmember sits around six months. The ISS also has the luxury of a 90 minute day/night cycle, 100% unfiltered sunlight for peak solar panel efficiency, regular resupply missions from Earth, and an escape route in the event of a catastrophic failure. That escape method (Soyuz capsules docked to the station) has not once been used, aside from a handful of instances where crew boarded their escape vehicles as a cautionary measure during unusually risky space debris events, an absolute non-issue on Mars’ surface.

Put simply: if humans can live in orbit for long periods, they can also survive on Mars with at least the same level of difficulty.

Getting there is the hardest part

By taking natural resources available on Mars (namely water and carbon dioxide) and using them to repopulate the planet’s withered atmosphere, it has long been hoped that the Martian surface might be brought much closer to that of Earth, with a thicker atmosphere translating into familiar air pressure and a far warmer climate. In its current state, humans would always need to wear pressure suits and carry oxygen when traveling beyond their Martian habitats, as Mars’ 0.06 bar atmosphere would be approximately as forgiving as the naked vacuum of space and only moderately warmer.

Terraforming could potentially alleviate those significant points against the Red Planet, although updated research published this year (2018) appears to indicate otherwise. In reality, Jakosky and Edwards’ study simply emphasizes and adds on to what should already have been wildly apparent – making desolate planets Earthlike is almost invariably going to be an unfathomably difficult (but by no means impossible) challenge, and is most likely beyond the reach of present-day humanity.

It also happens to be the case that terraforming as a concept is utterly irrelevant without the means to get to and – more importantly – transport respectable amounts of cargo to the bodies one hopes to one day transform. SpaceX’s BFR transportation system is one such acknowledgment of that problem – the issue with Mars colonization or really any basic human presence at all is not surviving after arrival, but instead actually getting there in the first place and doing so without taking decades or bankrupting entire nations.

Extremely affordable transport to, from, and between orbits happen to be the most unequivocal requirement for both a permanent human presence on other planets and have any hope at all of terraforming them, but it just so happens that the latter is 100% irrelevant and impossible without the former. Let’s seriously worry and argue about terraforming Mars once we can do so from the surface of the Red Planet and focus first on getting there.

Tesla to increase Full Self-Driving subscription price: here’s when

Published

Tesla will increase its Full Self-Driving subscription price, meaning it will eventually be more than the current $99 per month price tag it has right now.

Already stating that the ability to purchase the suite outright will be removed, Tesla CEO Elon Musk said earlier this week that the Full Self-Driving subscription price would increase when its capabilities improve:

“I should also mention that the $99/month for supervised FSD will rise as FSD’s capabilities improve. The massive value jump is when you can be on your phone or sleeping for the entire ride (unsupervised FSD).”

This was an expected change, especially as Tesla has been hinting for some time that it is approaching a feature-complete version of Full Self-Driving that will no longer require driver supervision. However, with the increase, some are concerned that they may be priced out.

$99 per month is already a tough ask for some. While Full Self-Driving is definitely worth it just due to the capabilities, not every driver is ready to add potentially 50 percent to their car payment each month to have it.

While Tesla has not revealed any target price for FSD, it does seem that it will go up to at least $150.

Additionally, the ability to purchase the suite outright is also being eliminated on February 14, which gives owners another reason to be slightly concerned about whether they will be able to afford to continue paying for Full Self-Driving in any capacity.

Some owners have requested a tiered program, which would allow people to pay for the capabilities they want at a discounted price.

Unsupervised FSD would be the most expensive, and although the company started removing Autopilot from some vehicles, it seems a Supervised FSD suite would still attract people to pay between $49 and $99 per month, as it is very useful.

Tesla will likely release pricing for the Unsupervised suite when it is available, but price increases could still come to the Supervised version as things improve.

This is not the first time Musk has hinted that the price would change with capability improvements, either. He’s been saying it for some time. In 2020, he even said the value of FSD would “probably be somewhere in excess of $100,000.”

Tesla starts removing outright Full Self-Driving purchase option at time of order

Tesla has chosen to axe the ability to purchase Full Self-Driving outright from a select group of cars just days after CEO Elon Musk announced the company had plans to eliminate that option in February.

The company is making a clear-cut stand that it will fully transition away from the ability to purchase the Full Self-Driving suite outright, a move that has brought differing opinions throughout the Tesla community.

Earlier this week, the company also announced that it will no longer allow buyers to purchase Full Self-Driving outright when ordering a pre-owned vehicle from inventory. Instead, that will be available for $99 per month, the same price that it costs for everyone else.

The ability to buy the suite for $8,000 for a one-time fee at the time of order has been removed:

This is a major move because it is the first time Tesla is eliminating the ability to purchase FSD outright for one flat fee to any of its vehicles, at least at the time of purchase.

It is trying to phase out the outright purchase option as much as it can, preparing people for the subscription-based service it will exclusively offer starting on February 14.

In less than a month, it won’t be available on any vehicle, which has truly driven some serious conversation from Tesla owners throughout the community.

There’s a conflict, because many believe that they will now lose the ability to buy FSD and not pay for it monthly, which is an attractive offer. However, others believe, despite paying $8,000 for FSD, that they will have to pay more money on top of that cost to get the unsupervised suite.

Additionally, CEO Elon Musk said that the FSD suite’s subscription price would increase over time as capabilities increase, which is understandable, but is also quite a conflict for those who spent thousands to have what was once promised to them, and now they may have to pay even more money.

Tesla Robotaxi has a highly-requested hardware feature not available on typical Model Ys

These camera washers are crucial for keeping the operation going, as they are the sole way Teslas operate autonomously. The cameras act as eyes for the car to drive, recognize speed limit and traffic signs, and travel safely.

Tesla Robotaxi has a highly-requested hardware feature that is not available on typical Model Ys that people like you and me bring home after we buy them. The feature is something that many have been wanting for years, especially after the company adopted a vision-only approach to self-driving.

After Tesla launched driverless Robotaxi rides to the public earlier this week in Austin, people have been traveling to the Lone Star State in an effort to hopefully snag a ride from one of the few vehicles in the fleet that are now no longer required to have Safety Monitors present.

BREAKING: Tesla launches public Robotaxi rides in Austin with no Safety Monitor

Although only a few of those completely driverless rides are available, there have been some new things seen on these cars that are additions from regular Model Ys, including the presence of one new feature: camera washers.

With the Model Y, there has been a front camera washer, but the other exterior “eyes” have been void of any solution for this. For now, owners are required to clean them manually.

In Austin, Tesla is doing things differently. It is now utilizing camera washers on the side repeater and rear bumper cameras, which will keep the cameras clean and keep operation as smooth and as uninterrupted as possible:

These camera washers are crucial for keeping the operation going, as they are the sole way Teslas operate autonomously. The cameras act as eyes for the car to drive, recognize speed limit and traffic signs, and travel safely.

This is the first time we are seeing them, so it seems as if Safety Monitors might have been responsible for keeping the lenses clean and unobstructed previously.

However, as Tesla transitions to a fully autonomous self-driving suite and Robotaxi expands to more vehicles in the Robotaxi fleet, it needed to find a way to clean the cameras without any manual intervention, at least for a short period, until they can return for interior and exterior washing.
