SpaceX ready to begin training astronauts for first private spacewalk
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).

Starlink gets its latest airline adoptee for stable and reliable internet access
The company said it plans to “rapidly integrate Starlink into its fleet,” and that the first Starlink-equipped aircraft will enter service this Summer.
SpaceX’s Starlink, the satellite internet program launched by Elon Musk’s company, has gotten its latest airline adoptee, offering stable and reliable internet to passengers.
Southwest Airlines announced on Wednesday that it would enable Starlink on its aircraft, a new strategy that will expand to more than 300 planes by the end of the year.
The company said it plans to “rapidly integrate Starlink into its fleet,” and that the first Starlink-equipped aircraft will enter service this Summer.
Tony Roach, Executive Vice President, Chief Customer and Brand Officer for the airline, said:
“Free WiFi has been a huge hit with our Rapid Rewards Members, and we know our Customers expect seamless connectivity across all their devices when they travel. Starlink delivers that at-home experience in the air, giving Customers the ability to stream their favorite shows from any platform, watch live sports, download music, play games, work, and connect with loved ones from takeoff to landing.”
Southwest also said that this is just one of the latest upgrades it is making to provide a more well-rounded experience to its aircraft. In addition to Starlink, it is updating cabin designs, offering more legroom, and installing in-seat power to all passengers.
Southwest became one of several airlines to cross over to Starlink, as reviews for the internet provider have raved about reliability and speed. Over the past year, Hawaiian Airlines, United Airlines, Alaska Airlines, airBaltic, Air France, JSX, Emirates, British Airways, and others have all decided to install Starlink on their planes.
This has been a major move away from unpredictable and commonly unreliable WiFi offerings on planes. Starlink has been more reliable and has provided more stable connections for those using their travel time for leisure or business.
Jason Fritch, VP of Starlink Enterprise Sales at SpaceX, said:
“We’re thrilled to deliver a connectivity experience to Southwest Airlines and its Customers that really is similar, if not better, than what you can experience in your own home. Starlink is the future of connected travel, making every journey faster, smoother, and infinitely more enjoyable.”
Starlink recently crossed a massive milestone of over 10 million subscribers.

Tesla nears closure of Full Self-Driving purchasing option
The move to bring FSD to this type of purchasing program comes after CEO Elon Musk noted in January that Tesla would move away from the outright purchase option.
Tesla is nearing the closure of its Full Self-Driving outright purchasing option, which will be removed on February 14, meaning Saturday will be the last time it can be bought as a non-subscription.
Tesla is aiming to move its Full Self-Driving suite to a subscription-only platform, a move that will enable people to only pay monthly for the semi-autonomous driving functionality.
The move to bring FSD to this type of purchasing program comes after CEO Elon Musk noted in January that Tesla would move away from the outright purchase option.
It is currently priced at $8,000 for the outright option to use Full Self-Driving, a substantial decrease compared to the $15,000 it was priced at one time. For the monthly subscription, it is just $99 per month, but that price will change, likely increasing as things get more advanced.
Tesla is overhauling its Full Self-Driving subscription for easier access
We say it will likely increase because there is no indication of how Tesla will price FSD. There has been some speculation that Tesla could utilize a tiered system to price FSD, which would potentially allow owners to pick and choose a set of features that would be most ideal for them.
This would potentially introduce an even more affordable option for FSD use, but this is unconfirmed. The reason many say this could be an option for Tesla is the fact that if the price goes up further, the take rate, which is currently around 12 percent at its most recent estimate, could be lower.
Musk needs 10 million active Full Self-Driving subscriptions to unlock one of the tranches of his newest compensation package.
The move to a subscription-only platform has its positives and negatives, and owners have been more than vocal about these since Musk confirmed the move.
Positives
- Lower barrier to entry and higher potential adoption
- Financially better for many users
- Easier transfers and brand loyalty
- Predictable recurring revenue for Tesla
- Access to the latest features
Negatives
- Higher long-term cost for loyal/long-term owners
- No true “ownership” or permanence
- Risk of future price hikes or even deactivation
- Perceived as of less value
- Impact on resale and used market
Overall, there is a split among the Tesla community in terms of what they see as the “right” way to handle this. Tesla is likely to shed more details on what its plans for the subscription-only platform will be, including pricing, in the coming weeks.

Elon Musk’s Boring Company selected for Universal Orlando tunnel project
The underground transport tunnel is designed to address the persistent gridlock surrounding International Drive.
Elon Musk’s The Boring Company has been selected for a proposed underground transit system connecting Universal Orlando Resort and the newly opened Universal Epic Universe.
The underground transport tunnel is designed to address the persistent gridlock surrounding International Drive.
As noted in a blooloop report, Universal’s Shingle Creek Transit and Utility Community Development District approved a resolution showing its intent to designate The Boring Company as the contractor for the project.
The agreement covers the full scope of the project, from the tunnel’s design, construction, and maintenance. The project has also been described in public documents as a “point-to-point innovative transportation” initiative with a 25-year agreement.
The proposed Boring Company tunnels would directly link Universal’s existing parks with Epic Universe, which sits roughly three miles away from Universal Orlando Resort. Today, buses are the only direct connection between the two destinations.
Project requirements were quite stringent. Bidders were required to demonstrate at least $75 million in bonding capacity, have a minimum of seven years of operational experience, and show prior delivery of a comparable project valued at $25 million or more within the past 15 years. The Boring Company, thanks in no small part to the Vegas Loop, meets these requirements.
The Orlando selection adds to The Boring Company’s growing portfolio of Loop-style systems. In Las Vegas, the Las Vegas Convention Center Loop has transported more than two million passengers in Tesla vehicles through underground tunnels since 2021. The greater Vegas Loop system is also under construction.
For now, residents in the area seem enthusiastic about the upcoming project. In a comment to Fox35, residents noted that the tunnels could improve traffic in the area.
“We are very congested at certain times and certain hours and that would certainly help with people not having to budget their time,” Mary Walters-Clark, a resident, stated. Another resident, Scott Heinz, echoed similar sentiments. “I think it would be a new opportunity to lessen traffic load and good for visitors as well,” he said.
The tunneling startup has started bringing its Loop projects to international locations. It recently signed a memorandum of understanding with Dubai’s Roads and Transport Authority to explore the development of a 17-kilometer underground Loop network beneath Dubai.
