SpaceX test emergency egress drills ahead of upcoming crew mission
NASA and SpaceX are progressing full steam ahead to an epic launch of the crewed Dragon spacecraft. Known as Demo-2, the mission is estimated to blast off in mid-to-late May, marking the first-ever flight of the Dragon with astronauts on board.
As part of that historic mission, two NASA astronauts — Doug Hurley and Bob Behnken — will launch to the International Space Station, where they will spend a still to be determined amount of time. The mission, deemed critical by NASA, is progressing as planned despite the coronavirus outbreak that’s spreading across the country.
To that end, NASA and SpaceX personnel, along with the crew, practiced essential safety drills and launch day procedures at the space agency’s Kennedy Space Center in Florida. SpaceX’s Crew Dragon capsule, and its Falcon 9 launcher, are equipped with numerous safety features designed to protect astronauts in the event of an emergency. And NASA wants to make sure they work.
One system — known as a launch escape system — was recently tested in-flight, proving that if something is wrong with the Falcon, the crews can be whisked away to safety by Dragon. But what if something goes wrong on the launch pad? The launchpad is equipped with a zipline that can be used to whisk astronauts quickly back to the ground should an emergency happen.
On April 3, @NASA and @SpaceX conducted an emergency egress exercise at Launch Complex 39A at @NASAKennedy.

On Friday (April 3), SpaceX and NASA completed an important test of that system. Teams simulated an “emergency egress”, running through a series of steps designed to transport the astronauts off the pad, and ensure their safety in the event that a serious problem crops up prior to liftoff.
“Teams rehearsed locating injured personnel on the 265-foot-level of the launch tower, loading them into the pad’s slidewire baskets and safely descending the tower, then successfully loading the injured participants into Mine Resistant Ambush Protected (MRAP) vehicles staged at the pad perimeter,” NASA officials wrote in an update.
This follows a series of simulations that the teams ran last month. They gathered in Firing Room 4, SpaceX HQ, and Johnson Space Center to run through launch simulations, ensuring the crew and launch control teams were ready for anything on the day of launch.
The flight is one for the history books as it marks the return of human spaceflight from U.S. soil since 2011. When the space shuttle program ended, NASA and other agencies around the world relied solely on Russia to ferry their astronauts to and from space. But that was only temporary as NASA turned to private companies to build its next generation of space taxis in 2014.
Ever since, the agency’s two contractors, SpaceX and Boeing, have worked to build its own version of an astronaut transport. Following a successful uncrewed test flight, SpaceX’s Crew Dragon capsule will be the first to launch astronauts for NASA. If this mission goes well, the California-based spaceflight company will be certified to launch astronauts on a regular basis.
NASA astronaut Shannon Walker has been assigned to the first operational crewed flight of @SpaceX's Crew Dragon, bound for the @space_station!
Pending a successful Demo-2 test, Walker, @Astro_illini, @VicGlover and @Astro_Soichi will launch this year. https://t.co/eYUN1Zt6Y0 pic.twitter.com/Fi4hCEZV3W

It’s first crew of four people — NASA astronauts Michael Hopkins, Victor Glover Jr., and Shannon Walker and Japanese astronaut Soichi Noguchi — are set to fly later this year or the beginning of 2021, if all goes as planned.
Boeing completed its uncrewed test flight in December of last year; however, its capsule experienced an inflight anomaly and was unable to reach the space station. Following an extensive review, Boeing has decided to repeat its uncrewed test flight before it launches people. That flight is expected for some time this fall.

Tesla FSD (Supervised) fleet passes 8.4 billion cumulative miles
The figure appears on Tesla’s official safety page, which tracks performance data for FSD (Supervised) and other safety technologies.
Tesla’s Full Self-Driving (Supervised) system has now surpassed 8.4 billion cumulative miles.
The figure appears on Tesla’s official safety page, which tracks performance data for FSD (Supervised) and other safety technologies.
Tesla has long emphasized that large-scale real-world data is central to improving its neural network-based approach to autonomy. Each mile driven with FSD (Supervised) engaged contributes additional edge cases and scenario training for the system.
The milestone also brings Tesla closer to a benchmark previously outlined by CEO Elon Musk. Musk has stated that roughly 10 billion miles of training data may be needed to achieve safe unsupervised self-driving at scale, citing the “long tail” of rare but complex driving situations that must be learned through experience.
The growth curve of FSD Supervised’s cumulative miles over the past five years has been notable.
As noted in data shared by Tesla watcher Sawyer Merritt, annual FSD (Supervised) miles have increased from roughly 6 million in 2021 to 80 million in 2022, 670 million in 2023, 2.25 billion in 2024, and 4.25 billion in 2025. In just the first 50 days of 2026, Tesla owners logged another 1 billion miles.
At the current pace, the fleet is trending towards hitting about 10 billion FSD Supervised miles this year. The increase has been driven by Tesla’s growing vehicle fleet, periodic free trials, and expanding Robotaxi operations, among others.
With the fleet now past 8.4 billion cumulative miles, Tesla’s supervised system is approaching that threshold, even as regulatory approval for fully unsupervised deployment remains subject to further validation and oversight.

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.
