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).
SpaceX has achieved an incredible milestone by launching its 11,000th Starlink satellite into orbit.
This accomplishment occurred during the Starlink Group 17-50 mission, which lifted off on August 19 at 04:01 UTC from Space Launch Complex 4 East at Vandenberg Space Force Base in California.

A Falcon 9 rocket carried 24 Starlink V2 Mini satellites on this flight, successfully deploying them into low Earth orbit approximately one hour after liftoff. The first stage booster, identified as B1097 on its twelfth flight, landed successfully on the droneship Of Course I Still Love You in the Pacific Ocean.
According to tracking data compiled around that date, this deployment brought the total number of Starlink satellites in orbit to just over 11,000.
The Starlink program began with test satellites known as Tintin A and B, launched on February 22, 2018. The first operational batch of 60 Starlink satellites followed on May 24, 2019, when a Falcon 9 rocket lifted off from Cape Canaveral. Those initial satellites marked the start of a rapid expansion that has continued for more than seven years.
SpaceX has conducted hundreds of dedicated Starlink missions since then, routinely launching batches of 20 to 30 satellites at a time using reusable Falcon 9 rockets. By mid-2026, the company had already surpassed 12,000 total satellites launched across all versions, with continuous replacements for units that deorbit as designed to manage space debris.
Looking ahead, SpaceX continues to expand the Starlink constellation to enhance global broadband coverage, capacity, and speed. The network already serves millions of users across more than 160 countries and supports applications ranging from residential internet to maritime, aviation, and emergency services.
Future plans center on next-generation hardware, including larger V3 satellites capable of delivering substantially higher throughput, which require the increased payload capacity of the Starship vehicle currently under development and testing.
In July, SpaceX submitted an application to the Federal Communications Commission seeking authority for a Gen3 constellation of up to 100,000 satellites. These spacecraft would operate in very low Earth orbit shells at altitudes near 325 kilometers and 475 kilometers. The filing requests use of existing Ku, Ka, V, and E band spectrum along with new greenfield W and D band frequencies between 92 and 275 GHz.
SpaceX states that the expanded system aims to deliver multi-gigabit symmetrical broadband to consumers, enterprises, governments, and billions of AI-powered devices worldwide while handling a majority of global internet traffic. Approval and subsequent deployment would depend on regulatory review and the operational readiness of Starship for high-volume launches.
This ambitious scale reflects SpaceX’s ongoing commitment to providing ubiquitous high-speed connectivity from space.
Tesla has opened a new sweepstakes to allow the public to be among the first to take an initial ride in a Cybercab. This all-electric, steering-wheel-less, pedal-less vehicle is the centerpiece of the company’s autonomous ride-hailing platform, Robotaxi.
There are two ways Tesla fans can get to Austin to take part in the first public rides of the Cybercab: by riding on the Robotaxi platform by August 23, or by mailing a very specific entry to their Headquarters at Gigafactory Texas.
Tesla announced the latter portion of the sweepstakes last night:
🚨 Want to win a trip to Austin to ride in one of the first Cybercab rides ever?
Here’s how:
Tesla has opened up a new sweepstakes to ride in a Cybercab upon its public launch. Here’s the details.
There are two methods of entry into the sweepstakes, and they are as follows:… pic.twitter.com/iJRd4evuWo

Tesla will give one entry into the sweepstakes if you mail a 3″ by 5″ piece of paper with your full name, mailing address, telephone number, email address, and date of birth to their address:
Tesla, Robotaxi Sweeps Event
1 Tesla Road,
Austin, TX 78725
There is a limit of one entry per stamped envelope. You can send as many as you’d like, but they must be in separate envelopes.
The company’s unique strategy to give people the opportunity to ride in a Cybercab before pretty much anyone else outside of the company is a hilarious but spot-on representation of how Tesla operates. In classic fashion, they had the perfect response to the event:

Cybercab will launch later this month, it appears, especially as it plans to announce the winners of the sweepstakes on August 25. The car has already been operating internally, as employees have been able to utilize the Cybercab for rides in some capacity, something it announced earlier this month.
Tesla weirdly confirms Cybercab employee rides, a huge milestone
Moving forward, the big goal is to get Cybercab out on the roads and integrated into the public Robotaxi fleet, one that will pick up real-world ride-hailers and give them a ride from Point A to Point B.
No matter which way you cut it, it appears Tesla is close to putting a vehicle with no steering wheel and no pedals on the road to help people travel autonomously.

Tesla has revealed plans through permit submissions for a massive Robotaxi charging hub in Austin, Texas.
Tesla plans to build the Supercharger hub in multiple phases, with the second phase potentially introducing wireless induction charging, something the company has been developing for the Robotaxi fleet.
Initially, 48 Tesla Robotaxi-geared Superchargers will be built on a lot just across from the St. Elmo, Texas, Service Center. There are about 80 additional spots that will not be impacted by phase 1 of the construction process.
Filings show that the second phase of the project will turn those 80 additional spots into wireless charging for Robotaxi, but it might be an error. The Key Notes state that item 3 is listed as “V4 Charging Cabinet to Support 80 Wireless Chargers in Phase 2. However, the drawings point to V3 Cabinets that are already tied to Superchargers:
There are roughly 128 total spots in the lot, but it is unclear if they will all be used for charging based on what appears to be some sort of typo in the blueprint.
A new Robotaxi fleet charging hub is coming soon to Austin, Texas!!

This is among the first Robotaxi charging hubs Tesla has started to develop, as it currently has four others planned throughout various areas: one in Phoenix, one in San Antonio, another in Irving, which will serve the Dallas-Fort Worth area, and another in Las Vegas.
These projects are necessary as Tesla expands its Robotaxi program. Now that preparations have started for the public launch of Cybercab, Robotaxi will likely be expanding aggressively, especially over the next two to three years.
Last night, The Information reported that Tesla was planning to launch Cybercab as soon as the end of August. Hours later, Tesla then announced it was launching a competition for fans to potentially ride in Cybercab during its first public rides.
Tesla’s plan to expand its charging infrastructure in the regions where Robotaxi will initially operate is great preparation for the expanding service. There is still a lot to do, including launching the Cybercab on time.
