SpaceX’s Elon Musk and his plans to send 1 million people to Mars
Elon Musk has big plans for Mars and it’s no secret that the SpaceX founder and CEO envisions a future where humans inhabit more than one planet, but how do we get there?
In a series of tweets, Musk outlined a plan to build a city on Mars by 2050, and fill it with 1 million people.
That may seem a bit outlandish but here’s how it would work.
SpaceX operates a fleet of Falcon 9 rockets that routinely launch and land, depositing satellites, cargo and soon people into space. However, in order to reach Mars, Musk and SpaceX need an even larger, more powerful rocket. That’s where Starship comes in.
In stark contrast to the classic black-and-white paint scheme of the Falcon family of rockets, Starship sports a shiny, stainless steel skin that gives off a futuristic vibe. And in true SpaceX fashion, the 387-foot ship will be reusable.
Starship, which is currently in development for future deep-space travel, will be able to ferry as many as 100 passengers beyond low-Earth orbit. The way to achieving that goal is by reducing the cost of spaceflight. He would like for anyone who wants to go to Mars, to be able to.
“Needs to be such that anyone can go if they want, with loans available for those who don’t have money,” Musk wrote.
To that end, Musk said he wants to build a fleet of at least 1,000 Starships—and launch at least three of them every day.
The Starship system is the latest in SpaceX’s troupe of increasingly larger rockets. In 2018, the California-based aerospace company launched and landed its Falcon Heavy rocket for the first time, generating 5 million pounds of thrust from the rocket’s 27 engines. But even that’s not powerful enough for Mars-based missions.
“Megatons per year to orbit are needed for life to become multi-planetary,” Musk tweeted on Thursday.
To date, the heaviest payload to successfully land on Mars was the Curiosity rover, which touched down on the red planet in 2012. That rover weighed in at 1 metric ton (2,200 lbs.). Much heavier payloads will be required if a city is to build on Mars. NASA, SpaceX and others around the world are currently working on ways to land even larger payloads.
Starship is one method currently in development. Combined with its Super Heavy booster would be powered by 41 next-generation Raptor engines, making it the most powerful launch system ever created—even more powerful than the Saturn V moon rocket. Each launch would pack enough thrust to send more than 100 tons (equivalent to seven fully loaded school buses’ worth of mass) and 100 people into orbit at a time.
But the ship would also be able to navigate the tenuous Martian atmosphere and land safely on the red planet’s surface.
Musk estimates that a fleet of 1,000 Starships, able to tote 100 megatons of stuff to Mars, would be required to build a permanent settlement. That fleet could transport about 100 passengers each, totaling 100,000 people per year.
Musk said a lot of work still needs to be done, especially in regards to propellant production. The Raptor engines Musk plans on using are powered by methane (as opposed to the Kerosene and liquid oxygen that power SpaceX’s Falcon series).
Mars has a generous supply of methane, which Musk hopes could be used to establish refueling depots on the red planet.
There’s a lot of work to do if humanity is to reach Mars. SpaceX is currently working around the clock to build its next prototype of the Starship spacecraft. (The previous mockup exploded during testing, but did prove that the craft could get off the ground.)
If all goes well with this iteration, we may see a Starship prototype fly again soon.

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.”
