NASA’s Mars InSight mission opens doors to hyper-affordable satellite industry
On November 26, 2018, NASA’s InSight lander arrived at Mars, our neighboring red planet, after a nearly seven month journey through deep space, but it didn’t travel alone. Twin satellites, collectively named “Mars Cube One” (MarCO), launched aboard the same Atlas V rocket on May 5, 2018 and followed closely behind. The MarCO mission was flown with InSight as a demonstration of communication and navigation capabilities for satellites in the CubeSat category. Each device measures about 14.5 inches by 9.5 inches, forming a six-unit CubeSat, and their mission represents a new chapter in citizen space exploration.
What are CubeSats?
CubeSats are tiny satellites meeting specific dimensions (multiples of 10 cm x 10 cm x 10 cm, 1 kg) and generally built with off-the-shelf components. They originated as an attempt to provide affordable access to space for the university science community and have since expanded into a multitude of other civilian projects, both non-profit and commercial. NASA in particular has worked to formalize the requirements for these types of satellite missions, even providing guides to assist with team efforts. CubeSat projects to date have included things like orbital telescopes, testing propulsion concepts (ion engines, solar sails), radio transmissions, and music via sonification.
Considering the average cost for a standard satellite is in the millions of dollars for both development and launch, the $50,000 or so the average CubeSat costs to build and launch is practically miniscule in comparison. Even projects with higher budget requirements can find funding readily enough, meaning that space exploration is no longer limited to large government projects and multimillion dollar corporate products. Now, with MarCO’s successful trip to Mars, Earth orbit is no longer the limitation for these small satellites. With companies like SpaceX pushing for multiplanetary habitation, enthusiastic citizen space explorers could perhaps assist with the scientific and technological research that will be needed to get us there.

The Mars Cube One Mission
MarCO’s primary mission was to demonstrate the ability to relay status information from the InSight lander to Earth as the craft descended onto the Martian surface. To accomplish this, the CubeSats transmitted signals to NASA’s already orbiting Mars Reconnaissance Orbiter which then forwarded the information to Earth. The successful transmissions provided scientists with information on InSight’s status much faster than would have otherwise been available due to orbital limitations. Additionally, the twin satellites used their own navigational systems to guide their journey to Mars, further advancing the cause of tiny satellites in deep space.
The success of the MarCO mission doesn’t just mean good news for future Mars citizen explorers. With the Moon back in the spotlight for exploratory missions and the growing interest in close, deep space targets like Venus, a wealth of data may be the near future arising from CubeSat projects. Where money was once a major inhibitor to space science projects, MarCO’s CubeSats have left the door wide open for the next generation of exploration to begin.

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.”

Tesla Model 3 becomes Netherlands’ best-selling used EV in 2025
More than one in ten second-hand electric cars sold in the country last year was a Tesla Model 3.
The Tesla Model 3 became the most popular used electric car in the Netherlands in 2025, cementing its dominance well beyond the country’s new-car market.
After years at the top of Dutch EV sales charts, the Model 3 now leads the country’s second-hand EV market by a wide margin, as record used-car purchases pushed electric vehicles further into the mainstream.
Model 3 takes a commanding lead
The Netherlands recorded more than 2.1 million used car sales last year, the highest level on record. Of those, roughly 4.8%, or about 102,000 vehicles, were electric. Within that growing segment, the Tesla Model 3 stood far ahead of its competitors.
In 2025 alone, 11,338 used Model 3s changed hands, giving the car an 11.1% share of the country’s entire used EV market. That means more than one in ten second-hand electric cars sold in the country last year was a Tesla Model 3, Auto Week Netherlands reported. The scale of its lead is striking: the gap between the Model 3 and the second-place finisher, the Volkswagen ID3, is more than 6,700 vehicles.
Rivals trail as residual values shape rankings
The Volkswagen ID.3 ranked a distant second, with 4,595 used units sold and a 4.5% market share. Close behind was the Audi e-tron, which placed third with 4,236 registrations. As noted by Auto Week Netherlands, relatively low residual values likely boosted the e-tron’s appeal in the used market, despite its higher original price.
Other strong performers included the Kia Niro, the Tesla Model Y, and the Hyundai Kona, highlighting continued demand for compact and midsize electric vehicles with proven range and reliability. No other model, however, came close to matching the Model 3’s scale or market presence.

Tesla Model Y Standard Long Range RWD launches in Europe
The update was announced by Tesla Europe & Middle East in a post on its official social media account on X.
Tesla has expanded the Model Y lineup in Europe with the introduction of the Standard Long Range RWD variant, which offers an impressive 657 km of WLTP range.
The update was announced by Tesla Europe & Middle East in a post on its official social media account on X.
Model Y Standard Long Range RWD Details
Tesla Europe & Middle East highlighted some of the Model Y Standard Long Range RWD’s most notable specs, from its 657 km of WLTP range to its 2,118 liters of cargo volume. More importantly, Tesla also noted that the newly released variant only consumes 12.7 kWh per 100 km, making it the most efficient Model Y to date.
The Model Y Standard provides a lower entry point for consumers who wish to enter the Tesla ecosystem at the lowest possible price. While the Model 3 Standard is still more affordable, some consumers might prefer the Model Y Standard due to its larger size and crossover form factor. The fact that the Model Y Standard is equipped with Tesla’s AI4 computer also makes it ready for FSD’s eventual rollout to the region.
Top Gear’s Model Y Standard review
Top Gear‘s recent review of the Tesla Model Y Standard highlighted some of the vehicle’s most notable features, such as its impressive real-world range, stellar infotainment system, and spacious interior. As per the publication, the Model Y Standard still retains a lot of what makes Tesla’s vehicles well-rounded, even if it’s been equipped with a simplified interior.
Top Gear compared the Model Y Standard to its rivals in the same segment. “The introduction of the Standard trim brings the Model Y in line with the entry price of most of its closest competition. In fact, it’s actually cheaper than a Peugeot e-3008 and costs £5k less than an entry-level Audi Q4 e-tron. It also makes the Ford Mustang Mach-E look a little short with its higher entry price and worse range,” the publication wrote.
