NASA is training SpaceX's first Crew Dragon astronauts for a much longer mission in space
NASA has revealed that the astronauts assigned to SpaceX’s Crew Dragon astronaut launch debut are training for a space station mission many times longer than initially planned.
Scheduled to deliver two NASA astronauts to and from the International Space Station (ISS) no earlier than (NET) late-April or May 2020, Crew Dragon’s Demo-2 mission will be the first crewed launch in SpaceX’s 18-year history. As previously noted on Teslarati (and by NASA itself, briefly), Demo-2 will also mark the first time in history that a privately-built spacecraft attempts to launch humans into orbit.
Still, NASA has funded the development of Crew Dragon (and competitor Boeing’s Starliner) not to achieve firsts but to restore the United States’ ability to launch its own astronauts to the ISS. Along those lines, both Crew Dragon (Demo-2) and Starliner’s (CFT) astronaut test flights were nominally designed to last about a week or two before returning NASA’s astronauts to Earth – a full end-to-end test for both extraordinarily complex vehicles. Two weeks, however, is simply not long enough for those astronauts to practically serve as full members of space station crew, something the ISS generally requires. In response, NASA has been seriously considering extending Boeing’s crewed test flight and has just recently suggested that SpaceX’s own Demo-2 test flight will be similarly upgraded.
About a month ago, SpaceX and NASA talked openly about the possibility of a longer-duration Crew Dragon astronaut launch debut for the first time, potentially extending the amount of time those astronauts are able to spend at the space station from about one week up to 1.5-3 months. This would allow Crew Dragon’s Demo-2 NASA astronauts – Bob Behnken and Doug Hurley – to serve as full members of the ISS crew, expanding the US presence from one to three astronauts.
Ars Technica’s Eric Berger offered some additional details about what exactly NASA might task Behnken and Hurley with on an extended flight earlier this month. Most importantly, the space agency wants the former astronaut – a Space Shuttle and extra-vehicular activity (EVA) veteran – to be (re)trained for spacewalks, allowing him to support an ever-growing to-do list of critical space station repairs and upgrades.

In effect, extending Crew Dragon’s astronaut flight test will make it almost identical to an “operational” flight where Crew Dragon ferries astronauts to the space station, docks for about six months, and finally returns the same astronauts to Earth at the end of its mission. More importantly, though, NASA’s decision to extend Commercial Crew Program (CCP) test flights – kickstarted with Boeing’s beleaguered Starliner spacecraft – is motivated by a desire to prevent the United States’ presence on the space station from dwindling or even regressing to zero in the near future.
Triggered by years of SpaceX and Boeing delays, NASA will now likely have to purchase more seats on Russian Soyuz launches if it wishes to maintain an full, uninterrupted presence on ISS for the next 12-24 months. After suffering numerous deeply concerning software failures on its first and only orbital launch, Boeing’s Starliner is unlikely to be ready to launch crew anytime soon. At the same time, although SpaceX is closer to its astronaut launch debut than ever before, it’s highly unlikely that Crew Dragon can singlehandedly support a full ISS complement of three NASA astronauts while Starliner works out its issues.

As such, NASA is looking everywhere it can to squeeze a bit more on-orbit time out of existing astronaut missions scheduled in the next year or so, and both Starliner and Crew Dragon’s test flights – barring showstoppers – are excellent opportunities. With NASA Johnson Space Center’s confirmation that both Behnken and Hurley are already deep into the extra training needed for an extended flight, chances are good that both astronauts will be ready for a one- or several-month mission by the time that NASA and SpaceX are ready and willing to launch.

Elon Musk’s X will start using a Tesla-like software update strategy
The initiative seems designed to accelerate updates to the social media platform, while maintaining maximum transparency.
Elon Musk’s social media platform X will adopt a Tesla-esque approach to software updates for its algorithm.
The initiative seems designed to accelerate updates to the social media platform, while maintaining maximum transparency.
X’s updates to its updates
As per Musk in a post on X, the social media company will be making a new algorithm to determine what organic and advertising posts are recommended to users. These updates would then be repeated every four weeks.
“We will make the new 𝕏 algorithm, including all code used to determine what organic and advertising posts are recommended to users, open source in 7 days. This will be repeated every 4 weeks, with comprehensive developer notes, to help you understand what changed,” Musk wrote in his post.
The initiative somewhat mirrors Tesla’s over-the-air update model, where vehicle software is regularly refined and pushed to users with detailed release notes. This should allow users to better understand the details of X’s every update and foster a healthy feedback loop for the social media platform.
xAI and X
X, formerly Twitter, has been acquired by Elon Musk’s artificial intelligence startup, xAI last year. Since then, xAI has seen a rapid rise in valuation. Following the company’s the company’s upsized $20 billion Series E funding round, estimates now suggest that xAI is worth tens about $230 to $235 billion. That’s several times larger than Tesla when Elon Musk received his controversial 2018 CEO Performance Award.
As per xAI, the Series E funding round attracted a diverse group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group, among others. Strategic partners NVIDIA and Cisco Investments also continued support for building the world’s largest GPU clusters.

Tesla FSD Supervised wins MotorTrend’s Best Driver Assistance Award
The decision marks a notable reversal for the publication from prior years, with judges citing major real-world improvements that pushed Tesla’s latest FSD software ahead of every competing ADAS system.
Tesla’s Full Self-Driving (Supervised) system has been named the best driver-assistance technology on the market, earning top honors at the 2026 MotorTrend Best Tech Awards.
The decision marks a notable reversal for the publication from prior years, with judges citing major real-world improvements that pushed Tesla’s latest FSD software ahead of every competing ADAS system. And it wasn’t even close.
MotorTrend reverses course
MotorTrend awarded Tesla FSD (Supervised) its 2026 Best Tech Driver Assistance title after extensive testing of the latest v14 software. The publication acknowledged that it had previously criticized earlier versions of FSD for erratic behavior and near-miss incidents, ultimately favoring rivals such as GM’s Super Cruise in earlier evaluations.
According to MotorTrend, the newest iteration of FSD resolved many of those shortcomings. Testers said v14 showed far smoother behavior in complex urban scenarios, including unprotected left turns, traffic circles, emergency vehicles, and dense city streets. While the system still requires constant driver supervision, judges concluded that no other advanced driver-assistance system currently matches its breadth of capability.
Unlike rival systems that rely on combinations of cameras, radar, lidar, and mapped highways, Tesla’s FSD operates using a camera-only approach and is capable of driving on city streets, rural roads, and freeways. MotorTrend stated that pure utility, the ability to handle nearly all road types, ultimately separated FSD from competitors like Ford BlueCruise, GM Super Cruise, and BMW’s Highway Assistant.
High cost and high capability
MotorTrend also addressed FSD’s pricing, which remains significantly higher than rival systems. Tesla currently charges $8,000 for a one-time purchase or $99 per month for a subscription, compared with far lower upfront and subscription costs from other automakers. The publication noted that the premium is justified given FSD’s unmatched scope and continuous software evolution.
Safety remained a central focus of the evaluation. While testers reported collision-free operation over thousands of miles, they noted ongoing concerns around FSD’s configurable driving modes, including options that allow aggressive driving and speeds beyond posted limits. MotorTrend emphasized that, like all Level 2 systems, FSD still depends on a fully attentive human driver at all times.
Despite those caveats, the publication concluded that Tesla’s rapid software progress fundamentally reshaped the competitive landscape. For drivers seeking the most capable hands-on driver-assistance system available today, MotorTrend concluded Tesla FSD (Supervised) now stands alone at the top.

Elon Musk’s Grokipedia surges to 5.6M articles, almost 79% of English Wikipedia
The explosive growth marks a major milestone for the AI-powered online encyclopedia, which was launched by Elon Musk’s xAI just months ago.
Elon Musk’s Grokipedia has grown to an impressive 5,615,201 articles as of today, closing in on 79% of the English Wikipedia’s current total of 7,119,376 articles.
The explosive growth marks a major milestone for the AI-powered online encyclopedia, which was launched by Elon Musk’s xAI just months ago. Needless to say, it would only be a matter of time before Grokipedia exceeds English Wikipedia in sheer volume.
Grokipedia’s rapid growth
xAI’s vision for Grokipedia emphasizes neutrality, while Grok’s reasoning capabilities allow for fast drafting and fact-checking. When Elon Musk announced the initiative in late September 2025, he noted that Grokipedia would be an improvement to Wikipedia because it would be designed to avoid bias.
At the time, Musk noted that Grokipedia “is a necessary step towards the xAI goal of understanding the Universe.”
Grokipedia was launched in late October, and while xAI was careful to list it only as Version 0.1 at the time, the online encyclopedia immediately earned praise. Wikipedia co-founder Larry Sanger highlighted the project’s innovative approach, noting how it leverages AI to fill knowledge gaps and enable rapid updates. Netizens also observed how Grokipedia tends to present articles in a more objective manner compared to Wikipedia, which is edited by humans.
Elon Musk’s ambitious plans
With 5,615,201 total articles, Grokipedia has now grown to almost 79% of English Wikipedia’s article base. This is incredibly quick, though Grokipedia remains text-only for now. xAI, for its part, has now updated the online encyclopedia’s iteration to v0.2.
Elon Musk has shared bold ideas for Grokipedia, including sending a record of the entire knowledge base to space as part of xAI’s mission to preserve and expand human understanding. At some point, Musk stated that Grokipedia will be renamed to Encyclopedia Galactica, and it will be sent to the cosmos.
“When Grokipedia is good enough (long way to go), we will change the name to Encyclopedia Galactica. It will be an open source distillation of all knowledge, including audio, images and video. Join xAI to help build the sci-fi version of the Library of Alexandria!” Musk wrote, adding in a later post that “Copies will be etched in stone and sent to the Moon, Mars and beyond. This time, it will not be lost.”
