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

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.”
