NASA astronauts go on quarantine ahead of historic SpaceX launch
NASA astronauts Behnken and Hurley had just a few days of downtime, following the end of their extensive training for SpaceX Crew Dragon, before being placed on a mandatory launch-related quarantine this week.
The pair have spent months training together in close proximity, so in a way, they’ve been quarantining together for some time now. But official quarantine started on May 13th.
Quarantine is a routine part of spaceflight for any astronaut that was first established during the Apollo program. It’s a necessary safety to measure to ensure that new crew members do not bring any contagions to the station. In order to make sure that Behnken and Hurley are not bringing the novel coronavirus to the space station, they (along with anyone who has close contact with them) will both be tested twice between now and launch.
SpaceX’s epic first crew launch is only a few weeks away. The California-based rocket builder has been busy preparing for the historic event. That mission is set to blast off from NASA’s Kennedy Space Center on May 27, at 4:33 p.m. EDT (2030 UTC).
When NASA announced the official launch date, SpaceX still had quite a bit of work to do before the big event. In the intervening weeks, however, SpaceX has completed several key items on its to-do list.

While officials from SpaceX and NASA were addressing members of the media and going over details of the launch and mission to follow, SpaceX engineers were conducting the final parachute test required before launch. That test went off without a hitch, and the company was able to close out another item.
Last week wrapped up the crew’s final week of training before launch.
Officially dubbed “flight crew health stabilization” by NASA, the quarantine is typically carried out near the launch site. For the past nine years, that has been in Kazakhstan, where Russia’s Soyuz spacecraft launches from. But this time around, the crew can choose to stay in the official astronaut quarters at Johnson Space Center in Houston or their own home if they can ensure that everyone in their household follows strict quarantine procedures.
Then, on May 20, Behnken and Hurley will travel to Florida, where they will reside in the astronaut quarters at Kennedy Space Center until they are ready to strap into their Crew Dragon spacecraft.
This exciting step means we are that much closer to launch. As it stands now, NASA and SpaceX are targeting May 27 at 4:33 p.m. EDT for liftoff, and everything is right on track. They will join NASA astronaut Chris Cassidy and cosmonauts Anatoly Ivanishin and Ivan Vagner, who are already on the orbital outpost.

The Boring Company’s Prufrock-2 emerges after completing new Vegas Loop tunnel
The new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.
The Boring Company announced that its Prufrock-2 tunnel boring machine (TBM) has completed another Vegas Loop tunnel in Las Vegas. The company shared the update in a post on social media platform X.
According to The Boring Company’s post, the new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.
The new tunnel marks the fourth tunnel constructed near Westgate Las Vegas as the Vegas Loop network continues expanding across the city.
The Boring Company also noted that the new tunnel surpassed its previous internal record of 2.26 miles for a single Vegas Loop segment.
Construction of the tunnel involved moving roughly 68,000 cubic yards of dirt. The excavation process also used about 4.8 miles of continuous conveyor belt, powered by six motors totaling 825 horsepower.
The Boring Company’s Prufrock-series all-electric tunnel boring machines are designed to support the rapid expansion of company’s underground transportation projects, including the growing Vegas Loop network. Prufrock machines are designed for reusability, thanks in no small part to their capability to be deployed and retrieved easily through their “porposing” feature.
The Vegas Loop, specifically the Las Vegas Convention Center (LVCC) Loop segment, has already been used during major events. Most recently, the LVCC Loop supported the 2026 CONEXPO-CON/AGG construction trade show, which was held from March 3-7, 2026.
As per The Boring Company, the LVCC Loop transported roughly 82,000 passengers across the convention center campus during the event’s duration.
CONEXPO-CON/AGG is one of the largest construction trade shows in North America, drawing more than 140,000 construction professionals from 128 countries this year.
The LVCC Loop forms the initial segment of the broader Vegas Loop network, which remains under active development as The Boring Company continues building new tunnels throughout the city.

Tesla gathers Cybercab fleet in Gigafactory Texas
Images and video of the Cybercab fleet were shared by longtime Giga Texas observer Joe Tegtmeyer in posts on social media platform X.
Tesla appears to be assembling a growing number of Cybercabs at Gigafactory Texas as preparations continue for the vehicle’s mass production. Recent footage shared online has shown over 30 Cybercabs being transported by trucks or staged near testing areas at the facility.
The images and video were shared by longtime Giga Texas observer and drone operator Joe Tegtmeyer in posts on social media platform X.
Interestingly enough, Tegtmeyer noted that many of the Cybercabs being loaded onto transport trucks were still equipped with steering wheels. This suggests that the vehicles are likely testing units rather than the final driverless configuration expected for the company’s Robotaxi service.
The vehicles could potentially be headed to testing sites across the United States as Tesla prepares to expand its Robotaxi fleet.
Additional footage captured at Gigafactory Texas also showed the Cybercab’s side and rear camera washer system operating as vehicles were being loaded onto transport trucks.
The growing number of Cybercabs at Giga Texas comes amidst the company’s announcement that the first production Cybercab has been produced at the facility. Full Cybercab production is expected to begin in April.
The vehicle is expected to play a central role in Tesla’s Robotaxi ambitions as the company looks to expand autonomous ride-hailing operations beyond its early deployments using Model Y vehicles.
Tesla has also linked Cybercab production to its proposed Unboxed manufacturing process, which assembles large vehicle modules separately before integrating them. The approach is intended to reduce production costs and accelerate output.
Musk has also noted that the Cybercab’s ramp will likely begin slowly due to the number of new components and manufacturing steps involved. However, he stated that once the process matures, Cybercab production could scale quickly.

Elon Musk’s xAI, creator of Grok and Grokipedia, celebrates its third birthday
xAI Memphis highlighted several of its milestones over the years in its celebratory post.
Elon Musk’s artificial intelligence startup xAI has marked its third anniversary. The update was shared in a post from the xAI Memphis account on social media platform X.
xAI Memphis highlighted several of its milestones over the years in its celebratory post.
As per xAI, it has built three massive data centers in the city, launched a coherent cluster of 330,000 GBs, created over 3,000 jobs, and paid over $30 million in taxes to local communities.
xAI’s Memphis operation has become a key part of the company’s infrastructure as the company works to train and deploy its Grok artificial intelligence models. Elon Musk has been quite optimistic about Grok’s potential, noting in the past that the large language model might have a shot at achieving artificial general intelligence (AGI).
xAI’s Memphis’ crown jewel is its Colossus supercomputer cluster. The project was announced in 2024 and has since become the home of one of the world’s largest AI compute facilities. The first phase of Colossus reached its initial 100,000 GPU operational milestone in just 122 days, or just about four months.
Industry figures such as Nvidia CEO Jensen Huang have praised the facility, noting that projects of similar scale typically take two to four years to complete.
xAI has cited Memphis’ central location, skilled workforce, and industrial infrastructure as key reasons for selecting the city as the home of its AI training operations. The company has also emphasized plans to expand the site further as it scales compute capacity for Grok and future AI models.
