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).

Tesla to launch in India in July with vehicles already arriving: report
Tesla is finally making serious moves toward launching in India, with showrooms opening in July, a report claims.
Tesla is finally bringing its business to India, a new report indicates, as the company is already shipping vehicles from China to the market where it has attempted to launch business for several years.
We first heard of Tesla planning to launch in India about a decade ago when CEO Elon Musk and Indian Prime Minister Narendra Modi met in California at the Fremont Factory in 2015.
Over the years, the two have hinted that the automaker would eventually land in India, but issues with import duties have delayed Tesla’s attempts.
Now, there seems to be some serious movement in Tesla’s plans, as it has reportedly shipped the first batch of vehicles from China to India, according to Bloomberg. The outlet says these are Model Y Rear-Wheel-Drive configurations.
Tesla is also planning for other parts of the launch, like preparing for Supercharging, aftermarket parts and merchandise purchasing for vehicle owners and fans, and spare parts from various regions, including the United States, China, and the Netherlands.
The company and the Indian government must have come to some sort of agreement that was catalyzed by Musk and Modi’s meeting in February in the U.S.
It is a long time coming, and it now gives Tesla access to an incredibly vast market in India, where a very small percentage of 2024’s total automotive sales were comprised of electric vehicles.
Another interesting tidbit about the launch is that the vehicles will be coming from Gigafactory Shanghai and not Gigafactory Berlin as previously thought. Reports from other publications, like Reuters, indicated the German production facility was building vehicles for India early last year.
India has a very strict policy that favors domestic manufacturing, which is why the import duties were so high for foreign automakers looking to bring their product into the market. These duties were reduced from 110 percent to just 15 percent, as long as companies aim to invest in India and meet certain investment and sales targets.

SpaceX and Elon Musk share insights on Starship Ship 36’s RUD
Starship Ship 36 experienced a Rapid Unscheduled Disassembly during a static fire attempt.
Elon Musk and SpaceX provided an explanation for the Rapid Unscheduled Disassembly (RUD) of Starship Ship 36 on Wednesday. As per Musk, preliminary data suggests that a nitrogen composite overwrapped pressure vessel (COPV) in the vehicle’s payload bay failed below its proof pressure.
On Wednesday evening, Ship 36 experienced a RUD during a static fire attempt. Videos of the incident that were shared online showed Starship Ship 36 exploding into a massive fireball at its launchpad in Starbase, Texas. Images taken in the aftermath of the explosion showed significant damage to the plumbing in the area. The site’s pad structure was also destroyed.
Elon Musk shared some information immediately after the incident. In a response to a post from space enthusiast @Erdayastronaut, Musk stated that “Preliminary data suggests that a nitrogen COPV in the payload bay failed below its proof pressure.”
Musk also noted that, “If further investigation confirms that this is what happened, it is the first time ever for this design.”
SpaceX provided more insight into the incident in a post on its official website.
“After completing a single-engine static fire earlier this week, the vehicle was in the process of loading cryogenic propellant for a six-engine static fire when a sudden energetic event resulted in the complete loss of Starship and damage to the immediate area surrounding the stand.
“The explosion ignited several fires at the test site, which remains clear of personnel and will be assessed once it has been determined to be safe to approach. Individuals should not attempt to approach the area while safing operations continue,” SpaceX wrote in its post.
SpaceX highlighted that despite Starship Ship 36’s RUD, the incident will not result in any hazards to the surrounding communities in the Rio Grande Valley. And in a post on X, SpaceX also confirmed that everyone in the Starship team was safe and accounted for after Ship 36’s explosion.
While Ship 36’s RUD is a speed bump for the Starship program, SpaceX is a company that is known to grow stronger with every adversity. Thus, it would not be surprising if SpaceX implemented numerous improvements to Starship after this incident–improvements that would make the vehicle more reliable and safer than before.

Tesla has started rolling out initial round of Robotaxi invites
Tesla is putting safety above all in its initial Robotaxi rollout.
Tesla has started rolling out an initial round of invites for its upcoming Robotaxi service in Austin, Texas.
Screenshots shared by several Tesla community members who received the invites provided a quick overview of the autonomous ride-hailing service.
As noted in a techAU report, the initial round of Robotaxi service invites has gone to longtime Tesla owners and active members of the EV community. These include owners such as @SawyerMerritt, @BLKMDL3, @WholeMarsBlog, @ItsKimJava, and @HerbertOng, all of whom shared screenshots of the invitation that Tesla has sent about the upcoming service.
You’re Invited to Early Access of Tesla Robotaxi!
The Future is Now! You’re invited to Early Access of Tesla’s Robotaxi service in Austin, TX!
As an Early Access rider, you can be among the first to use our new Robotaxi App and experience an autonomous ride within our geofenced area in Austin. Through this exclusive preview, you’ll have the opportunity to provide valuable feedback on our Robotaxi service.
Based on Tesla’s message, it appears that participation in the service would be strictly invite-only for now. Participants must also download Tesla’s dedicated Robotaxi App to hail a ride. Rides can also be requested and initiated to and from any location within a geofenced area of Austin.
The robotaxi service will be available from 6:00 AM to 12:00 AM, seven days a week, though these hours may change depending on factors such as inclement weather. Interestingly enough, Tesla is inviting the first participants of the Robotaxi program to share photos and videos of their experience with the service.
While the vehicles themselves are autonomous and would operate without human input, the Robotaxis would still be accompanied by a Tesla staff member to monitor the vehicle. This strategy suggests that Tesla is really putting safety above all in its initial Robotaxi rollout.
