Virgin Galactic reaches space in rocket-powered plane, eyes space tourism in 2019

Published

Virgin Galactic, the space tourism company founded by entrepreneur Richard Branson, has successfully made it to space for the first time with VSS Unity, their SpaceShipTwo-class rocket-powered plane, during the craft’s 4th test flight. This accomplishment makes Virgin the first US-based venture to carry humans to the edge of space since the Space Shuttle program ended in 2011, edging out others with similar goals such as SpaceX and Blue Origin. After taking off at 7:11 am this morning and detaching from WhiteKnightTwo, its custom airliner mothership, pilots Mark “Forger” Stucky and Rick “CJ” Sturckow reached a height 51.4 miles high in the craft to the edge of the stratosphere where they experienced weightlessness and the curvature of the Earth. This success brings the company one step closer to civilian tourist trips, something Branson hopes to achieve as early as 2019.

Unlike a traditional rocket which takes off from the ground, VSS Unity is flown to 43,000 feet underneath a specially designed airliner before being dropped and subsequently lighting up its rocket engines to power it vertically to an even higher altitude. After a 60-second engine burn speeds the craft to nearly three times the speed of sound, it continues its ascent, coasting until it reaches maximum altitude. A special “feather” system is then used for reentry, wherein the craft folds its wings and behaves like a traditional space capsule until the air thickens again, at which time the wings unfold again and behave like a space plane, gliding back to Earth and landing on a landing strip.

Becoming a passenger on one of VSS Unity’s future flights doesn’t come cheap, the price tag being $250,000 per 90-minute flight. However, given the 700 or so paid reservations, including several celebrities, it’s not the money that’s the challenge, it’s the technology. On October 31, 2014, Virgin suffered a crippling setback with the death of co-pilot Mike Alsubry and injury of pilot Peter Siebold when a predecessor craft crashed due to a combination of human error and an engineering flaw. The company received an abundance of criticism focused on whether the danger of space tourism made the rewards worthwhile, but after following recommendations set forth by the National Transportation Safety Board’s report on the incident along with further design and safety enhancements, they forged ahead to make today’s event a reality. Branson started Virgin Galactic in 2004.

At 51.4 miles high, VSS Unity reached the technical definition of space, earning its pilots commercial astronaut wings by the US Federal Aviation Administration, although the usual international standard is the 62-mile “Karman line”. A typical NASA “sounding rocket”, a small rocket generally launched with equipment on board to take measurements and scientific experiments during an approximately 30-minute sub-orbital flight only, reaches anywhere from 30-80 miles above the Earth. That said, the lower altitude of VSS Unity also provides an opportunity for research, serving the dual-purpose of science and recreation. Four research payloads from NASA’s Flight Opportunities Program were on board its historic test flight as well as a test dummy, making the trip revenue-earning for the first time as well.

Virgin Galactic has more tests of VSS Unity planned before moving to Spaceport America in New Mexico where it will set up its tourism operation. Branson hopes to compete directly with Blue Origin, the rocket company founded by Amazon’s Jeff Bezos which also plans to ferry customers to space. Bezos’s venture will use a more traditional, reusable ground-based rocket, the New Shepard, that lands after returning from sub-orbit similar to SpaceX’s Falcon 9 first stages. Unlike Virgin, crewed flights and “pre-sales” have not yet been part of Blue Origin’s process, but plenty of information is available for potential customers on its website.

The parent company of Virgin Galactic (Virgin) has another space-based venture in its wings: Virgin Orbit. Using a system similar to NASA’s Pegasus rocket, a small rocket complete with payload will launch from a modified Boeing 747-400 airliner, the combo being called LauncherOne and Cosmic Girl, respectively. The company has its sights set on the small satellite industry, identifying a need that’s not currently being met by other launch providers, and its business model centers on proving low-cost access to space for existing companies, students, entrereneurs, and other types hoping to use space as part of their research or business endeavors.

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

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.
