SpaceX’s first Crew Dragon NASA astronauts suit up for spacesuit-focused launch rehearsal
While a great deal of work remains before SpaceX and NASA are ready to set a date for Crew Dragon’s inaugural astronaut launch (Demo-2) both teams continue to actively prepare for the milestone mission.
Most recently, NASA has published photos detailing a critical (and literal) dress rehearsal with astronauts Col. Bob Behnken and Col. Doug Hurley, set to become the first astronauts to ride SpaceX’s Crew Dragon to orbit and dock with the International Space Station (ISS). This particular test centered around the process of suiting up in SpaceX’s iconic, custom-built spacesuits and simulated pre-launch procedures in a Crew Dragon simulator located at SpaceX’s Hawthorne, CA headquarters.
A literal dress rehearsal
On Thursday, an official NASA Astronaut account tweeted that SpaceX’s first two Commercial Crew astronauts had recently completed a dress rehearsal test of the spacesuits that they will wear during Crew Dragon’s inaugural crewed launch to the ISS. Bob Behnken and Doug Hurley participated in a full “suit-up & leak checks” rehearsal with their iconic SpaceX-built suits and the same Ground Support Equipment (GSE) hardware that will be used during Demo-2. This dress rehearsal also serves to familiarize the SpaceX and NASA ground support crew with the astronaut suit-up process, and multiple technicians and flight engineers are visible in the background.
The new spacesuits made their press debut last summer at a media event held at SpaceX headquarters in Hawthorne, California. Not only are they uniquely beautiful and modernist, but SpaceX’s spacesuits are also designed first and foremost with functionality in mind. SpaceX hired its own team of seamstresses and focused heavily on integrating 3D printing into suit production, resulting in an end-product that is simultaneously strikingly minimalistic and extremely usable. For example, the helmets Behnken and Hurley are seen wearing use 3D printing to integrate extremely complex life support systems, a built-in microphone and speaker communications array, a seamless multi-hinged visor, and more.


The suits are also designed to allow for easy maneuverability and a seamless user experience within the Dragon capsule. The attached gloves of the suit use conductive leather to allow the astronauts to interact with the Crew Dragon’s primary controls, a set of large touchscreens. Apple iPads will additionally be mounted directly on the thighs of the astronauts to serve as an even more convenient (and redundant) method of interfacing with Dragon’s controls, among other things.
While the suits are designed to be pressurized to support the astronauts in the event of a life-threatening event that may occur aboard Dragon, they are not meant for spacewalks or prolonged exposure to the vacuum of space.

Behnken, Hurley, and other Commercial Crew astronauts have been included in the development of their suits since day one and each flight suit has been carefully tailored to fit each future Crew Dragon astronaut. Having the opportunity to run through a launch day dress rehearsal allows everyone in the process to become familiarized with the specialized procedures that will occur ahead of boarding the Dragon capsule.
Crew Dragon sidesteps the norm
Unlike previous crewed NASA launches, SpaceX plans to have astronauts board Crew Dragon before launch vehicle fueling begins. This new approach to crew loading has become known as “Load-and-Go.” This procedure is extremely familiar to SpaceX, as the company supercools the liquid oxygen and kerosene propellant used by Falcon 9 and Heavy to significantly improve the performance of both rockets.
SpaceX has made the rational argument that boarding astronauts before fueling is actually significantly safer than the traditional method of ingressing astronauts while the rocket is fully fueled. Once inside Crew Dragon, the spacecraft’s SuperDraco abort system would be armed, theoretically protecting its astronauts from any conceivable explosion-related vehicle failure, whereas a fueled rocket failing during ingress could easily kill anyone in close proximity for the boarding procedure.

According to NASA, possible dates for Crew Dragon’s Demo-2 astronaut launch debut are under review. In a mid-July conference call with SpaceX and NASA officials, neither were particularly confident that Demo-2 would be ready to launch before the end of 2019, although they specifically did not rule the possibility out. More likely than not, Crew Dragon Demo-2 will slip into early 2020 as a result of a catastrophic explosion that destroyed Crew Dragon capsule C201 during static fire testing earlier this year.

Elon Musk fires back after Wikipedia co-founder claims neutrality and dubs Grokipedia “ridiculous”
Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”
Elon Musk fired back at Wikipedia co-founder Jimmy Wales after the longtime online encyclopedia leader dismissed xAI’s new AI-powered alternative, Grokipedia, as a “ridiculous” idea that is bound to fail.
Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”
Wales made the comments while answering questions about Wikipedia’s neutrality. According to Wales, Wikipedia prides itself on neutrality.
“One of our core values at Wikipedia is neutrality. A neutral point of view is non-negotiable. It’s in the community, unquestioned… The idea that we’ve become somehow ‘Wokepidea’ is just not true,” Wales said.
When asked about potential competition from Grokipedia, Wales downplayed the situation. “There is no competition. I don’t know if anyone uses Grokipedia. I think it is a ridiculous idea that will never work,” Wales wrote.
After Grokipedia went live, Larry Sanger, also a co-founder of Wikipedia, wrote on X that his initial impression of the AI-powered Wikipedia alternative was “very OK.”
“My initial impression, looking at my own article and poking around here and there, is that Grokipedia is very OK. The jury’s still out as to whether it’s actually better than Wikipedia. But at this point I would have to say ‘maybe!’” Sanger stated.
Musk responded to Sanger’s assessment by saying it was “accurate.” In a separate post, he added that even in its V0.1 form, Grokipedia was already better than Wikipedia.
During a past appearance on the Tucker Carlson Show, Sanger argued that Wikipedia has drifted from its original vision, citing concerns about how its “Reliable sources/Perennial sources” framework categorizes publications by perceived credibility. As per Sanger, Wikipedia’s “Reliable sources/Perennial sources” list leans heavily left, with conservative publications getting effectively blacklisted in favor of their more liberal counterparts.
As of writing, Grokipedia has reportedly surpassed 80% of English Wikipedia’s article count.

Tesla Sweden appeals after grid company refuses to restore existing Supercharger due to union strike
The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons.
Tesla Sweden is seeking regulatory intervention after a Swedish power grid company refused to reconnect an already operational Supercharger station in Åre due to ongoing union sympathy actions.
The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons. A temporary construction power cabinet supplying the station had fallen over, described by Tesla as occurring “under unclear circumstances.” The power was then cut at the request of Tesla’s installation contractor to allow safe repair work.
While the safety issue was resolved, the station has not been brought back online. Stefan Sedin, CEO of Jämtkraft elnät, told Dagens Arbete (DA) that power will not be restored to the existing Supercharger station as long as the electric vehicle maker’s union issues are ongoing.
“One of our installers noticed that the construction power had been backed up and was on the ground. We asked Tesla to fix the system, and their installation company in turn asked us to cut the power so that they could do the work safely.
“When everything was restored, the question arose: ‘Wait a minute, can we reconnect the station to the electricity grid? Or what does the notice actually say?’ We consulted with our employer organization, who were clear that as long as sympathy measures are in place, we cannot reconnect this facility,” Sedin said.
The union’s sympathy actions, which began in March 2024, apply to work involving “planning, preparation, new connections, grid expansion, service, maintenance and repairs” of Tesla’s charging infrastructure in Sweden.
Tesla Sweden has argued that reconnecting an existing facility is not equivalent to establishing a new grid connection. In a filing to the Swedish Energy Market Inspectorate, the company stated that reconnecting the installation “is therefore not covered by the sympathy measures and cannot therefore constitute a reason for not reconnecting the facility to the electricity grid.”
Sedin, for his part, noted that Tesla’s issue with the Supercharger is quite unique. And while Jämtkraft elnät itself has no issue with Tesla, its actions are based on the unions’ sympathy measures against the electric vehicle maker.
“This is absolutely the first time that I have been involved in matters relating to union conflicts or sympathy measures. That is why we have relied entirely on the assessment of our employer organization. This is not something that we have made any decisions about ourselves at all.
“It is not that Jämtkraft elnät has a conflict with Tesla, but our actions are based on these sympathy measures. Should it turn out that we have made an incorrect assessment, we will correct ourselves. It is no more difficult than that for us,” the executive said.

Music City Loop could highlight The Boring Company’s real disruption
The real story behind the tunneling startup’s Nashville tunnel project is the company’s targeted $25 million per mile construction cost.
Recent commentary on social media has highlighted what could very well prove to be The Boring Company’s real disruption.
The analysis was shared by tech watcher Aakash Gupta on social media platform X, where he argued that the real story behind the tunneling startup’s Nashville tunnel project is the company’s targeted $25 million per mile construction cost.
According to Gupta’s breakdown, Nashville’s 2018 light rail proposal was priced at roughly $200 million per mile. New York’s East Side Access project reportedly cost about $3.5 billion per mile, while Los Angeles Metro expansion projects have approached $1 billion per mile.
By comparison, The Boring Company has stated it can construct 13 miles of twin tunnels in the Music City Loop for between $240 million and $300 million total. That implies a cost near $25 million per mile, or roughly a 95% reduction from industry averages cited in the post.
Several technical departures from conventional tunneling allow the Boring Company to lower its costs, from its smaller 12-foot diameter tunnels to its fully electric Prufrock machines that are designed to mine continuously with no personnel inside the tunnel and their capability to “porpoise” for easy launch and retrieval.
Tesla and Space CEO Elon Musk responded to the post on X, stating simply that “Tunnels are so underrated.”
The Boring Company has seen some momentum as of late, with the company recently signing a construction contract in Dubai and the Universal Orlando Loop progressing. Recent reports have also pointed to tunnels potentially being constructed to solve traffic congestion issues near the Giga Nevada area.
While The Boring Company’s tunnels have so far been used for Loop systems publicly for now, Elon Musk recently noted that the tunneling startup’s underground passages would not be limited only to ride-hailing vehicles.
In a reply to a post on X which discussed the specifications of the Music City Loop, Musk clarified that “any fully autonomous electric cars can use the tunnels.” This suggests that vehicles potentially running systems like FSD Supervised, even if they are not Teslas, could be used in systems like the Music City Loop in the future.
