SpaceX ready to begin training astronauts for first private spacewalk

SpaceX could conduct the first private spacewalk in history as few as six months from now.

Two members of the “Polaris Program” say that SpaceX could begin training private astronauts for the first private spacewalk in spaceflight history as early as May or June 2022.

Revealed earlier this year, the Polaris Program is a sort of hybridization of orbital spaceflight tourism and technology development and has one primary goal: to “rapidly advance human spaceflight capabilities.” Created in partnership with SpaceX by billionaire and Shift4 Payments founder Jared Isaacman, who also funded and flew on SpaceX’s first private Crew Dragon launch, Polaris aims to pick up where Inspiration4 left off last year.

While it will still be affiliated with and seek to help St. Jude Children’s Research Hospital, the Polaris Program will focus on the development of several crucial technologies that SpaceX will need to accomplish its ultimate goal of spreading humanity throughout our solar system.

One of those crucial technologies is a cheap, reliable, and easy-to-use spacesuit that will allow future SpaceX astronauts to work outside of the safety of their spacecraft in the vacuum of space, and, one day, walk on the surfaces of other planets and moons. For Crew Dragon, SpaceX has already developed an ‘intra-vehicular activity’ or IVA pressure suit that all Dragon astronauts must wear during mission-critical maneuvers. In the event of capsule depressurization, the suits would be able to keep Dragon astronauts alive inside the capsule for at least a few days, supplying them with clean air and maintaining enough pressure to avoid altitude sickness (or worse).

However, because IVA suits generally prioritize unpressurized mobility, the astronauts inside them can do very little when the suits are fully pressurized. At sea level, every person on Earth is subjected to standard atmospheric pressure, which amounts to about 101 kilopascals or 14.5 pounds per square inch. In a spacesuit, the suit itself must maintain a pocket of air at similar pressures, ultimately meaning that the outer skin of a suit must resist the same force. To put that into context, even operating at the absolute minimum pressures that humans can realistically tolerate and use (4-6 psi), simply moving one’s arm in an IVA suit could require hundreds of pounds or kilograms of force.

Even in NASA’s aging extra-vehicular activity (EVA) spacesuits, which feature mechanical joints and other upgrades meant to make movement and life easier inside them, spacewalks are one of the most brutal and exhausting physical activities conceivable, requiring extraordinary levels of near-constant exertion for hours on end. According to comments made to Spaceflight Now by Jared Isaacman and by pilot Scott Poteet in an interview covered by AmericaSpace, SpaceX’s first EVA suit will be quite basic. To some extent, they will be heavily modified versions of SpaceX’s existing IVA suit design, but with much more advanced thermal management, an improved helmet/visor, and – most importantly – the addition of a number of mechanized joints.

As was the case with early NASA EVA suits developed in the 1960s, SpaceX’s first EVA suits will receive consumables, power, and communications through cables (tethers) that connect to Dragon’s life support. It will take SpaceX some time to develop a miniaturized, portable life support system as safe and capable as the packs used on NASA’s EVA suits. A tethered EVA suit will still allow SpaceX or private astronauts to perform EVAs and work on or inspect the exterior of their Crew Dragon or Starship spacecraft – capabilities that could save lives in certain emergency scenarios. SpaceX’s first priority, then, will be to make sure that the basics work well in space and that the suits actually allow astronauts to perform tasks that require good finger and limb dexterity without immediately exhausting themselves.

“You’re adding lots of redundancies in the suit that don’t exist today, since it’s more last line of defense,” Isaacman said, referring to the differences between SpaceX’s current suit and the new extravehicular spacesuit. “You have a new visor, new seals, then mobility, joints everywhere for increased mobility and dexterity in the fingers and such. I think, visually, it will be more along the lines of what it currently looks like, but very much like a new suit.”

Spaceflight Now – May 10th, 2022

The first of up to three Polaris missions – Polaris Dawn – is currently scheduled to launch as early as November 2022. All four private astronauts – made up of two Polaris employees and two SpaceX employees – will wear the new EVA suits in place of their usual IVA suits, while only two members of the crew will ultimately attempt to exit the capsule and perform a single EVA that could last roughly 30-90 minutes. To do so, the entire Dragon will be depressurized and one of two hatches opened will be opened, while the the other two EVA-suited astronauts will simply remain in their seats. Regardless of the outcome, it will be the first private spacewalk in the history of spaceflight.

The astronauts training to prepare for Polaris Dawn will focus heavily on the EVA, offering either the two chosen crew members or all four candidates an opportunity to experience deep-sea diving and test EVA suits both underwater and inside a Dragon capsule simulator.

Beyond supporting SpaceX’s EVA spacesuit development, Polaris Dawn’s crew will also conduct a range of science experiments, attempt to connect to high-speed internet in orbit through Starlink laser links, and even try to break the record for the highest Earth orbit reached by a crewed spacecraft (1400 km / 870 mi).

Tesla ships new feature that silences neighborhood Supercharger complaints

Tesla is shipping a new feature that silences neighborhood Supercharger complaints, prompting drivers to be aware of those who might be impacted by excessive noise nearby.

Tesla is now rolling out a new location-specific “Quiet Charging Zone” that prompts drivers to lower their vehicle’s audio volume in an effort to make things comfortable for everyone, even those who are not Tesla owners.

This is an impactful feature that will resolve many complaints from those who are living nearby.

When a Tesla plugs into this Supercharger and its media volume exceeds a certain level, the vehicle’s central touchscreen displays a polite notification: “Could you turn the volume down? Please be mindful of our neighbors.”

Accompanying the message is a prominent “Lower” button. One tap automatically reduces the audio to a more considerate level. Physical “Quiet Charging Zone” signs posted at the station reinforce the request, creating a cohesive experience that blends digital nudges with on-site reminders.

This feature highlights Tesla’s unique advantages. Unlike traditional automakers, Tesla owns both the vehicle software and the charging infrastructure.

Engineers can detect the precise location via GPS, trigger context-aware prompts, and deploy changes fleet-wide in hours or days without recalls or dealer visits. No public release notes highlighted the change, suggesting it was a quiet, site-specific rollout designed to test effectiveness before potential expansion.

These are usually referred to as “Undocumented Changes.”

Beyond immediate noise reduction, the initiative underscores Tesla’s customer- and community-focused ethos. While EVs are inherently quieter than combustion-engine vehicles, auxiliary behaviors like loud infotainment can still create friction in dense cities. Tesla’s rapid response turns potential conflict into an opportunity to demonstrate thoughtful engineering.

As Tesla expands its Supercharger network, which is now open to other EVs in many places, features like location-based quiet modes could become standard tools for harmonious integration into neighborhoods.

Ferrari unveils its Luce EV, and its reception has been a disaster

Ferrari unveiled its Luce EV over the weekend, and so far, its reception has been an absolute disaster, gathering negative reactions from a wide variety of people, including former executives.

The stock even took a hit on its first day of trading following the unveiling, dropping over 7 percent at one point.

Ferrari moving to EVs from its traditional V12s and mid-engine sports cars is a massive move. It was designed by Sir Jony Ive and Marc Newsom’s LoveFrom studio, which is known for design work for tech giant Apple. “Luce” means “light” in Italian, so Ferrari drew inspiration for its name from its sleek design, characterized by a smooth, sculpted body with rounded edges.

But its reception has been far from what Ferrari expected. The overall design has drawn some harsh criticism since its reveal, and it is simply stunning that such a storied company, with a rich history of beautiful, powerful cars has revealed a design that many are not a fan of.

Responses to the design were widely negative, with some saying, “Enzo is rolling in his grave,” and “This looks like a Nissan LEAF with a bad body kit.”

Former Ferrari Chairman Luca di Montezemolo said:

“If I said what I really think, I’d harm Ferrari. We’re risking the destruction of a myth, I’m very sorry about that. I hope they at least remove the Prancing Horse from that car.”

Ferrari has scaled back EV commitments in the past, primarily in response to weaker-than-expected demand for its electric powertrains.

Priced at roughly $640,000 in the U.S., it is tough to see how this car will ever truly live up to the massive expectations many had for it. It almost feels like, to a certain extent, Ferrari is looking for a way to get out of building EVs.

Tesla unveils juicy new detail on the Roadster and hints at new unveil timeline

Tesla unveiled a juicy new detail on the Roadster, its long-delayed supercar project, and additionally hinted at a new unveiling timeline, as it appears yet another month will pass without seeing the capabilities of the vehicle.

Vice President of Vehicle Engineering at Tesla, Lars Moravy, revealed on the Ride the Lightning podcast that the Roadster will be built at Gigafactory Texas, adding that “you’ll start to see a lot of things unfold in the next months.”

While we get a good detail on the plant of manufacture, we also get another letdown, as it appears the unveiling event will not take place in May, as CEO Elon Musk hinted during the Earnings Call.

The Roadster was first unveiled back in 2017, alongside the Semi, which entered production earlier this year. It was Tesla’s attempt at a true supercar; it would be rare, expensive, and lightning quick, among other incredible capabilities, like potentially hovering for a short period thanks to a collaboration project with SpaceX.

However, the vehicle was set to be delivered in 2020. Parts and supply chain issues due to the COVID-19 pandemic started these delays, and since then, Tesla, and specifically Musk, have wanted to push the capabilities of the Roadster to somewhere the human mind may not be able to currently comprehend.

Both Chief Designer Franz von Holzhausen and Moravy have said many things about the Roadster over the past few years, hinting that the car truly could be worth the wait. However, the continuous delays we’ve seen have undoubtedly been discouraging.

With that being said, it’s not like Tesla has been doing nothing. Instead, the company has been focusing on revamping current models, phasing out others, and working on developing the cars of the future, specifically, the Cybercab, which entered production at Giga Texas in April.

Despite the Roadster’s delays, there is still a ton of anticipation for the vehicle to be released. It will have a steering wheel, as Musk said it will be “the best of the last of the human-driven cars.”
