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.

Tesla launches V2L Outlet Adapter for Premium Model Y in the U.S.

Published

Tesla has launched a new Vehicle-to-Load (V2L) Outlet Adapter for Premium Model Y vehicles in the United States, meaning you can now power devices like laptops or light strings with your vehicle’s battery.

It appears the capability will be available for any Model Y Premium trim, including those that were purchased prior to the Adapter being launched. It will also only impact Juniper Model Y vehicles, so the first-gen owners will unfortunately not have access to this capability.

If your Model Y was purchased before Tesla renamed the trim levels to “Premium” and “Standard,” it does not seem to be compatible. My Model Y is technically a Premium build, as it is the Long Range All-Wheel-Drive. However, Tesla says it is not compatible with my vehicle.

For $80, you can now utilize your car as a portable charger for small appliances or devices. This is perfect for things like tailgates, concerts, or camping, as you can now plug in devices that you might use. Those string lights for camping? That laptop for the other games that are on at the tailgate?

They’ll both utilize energy from your Tesla’s battery to be powered. This is the first time Tesla has expanded the capability to vehicles outside of the Model Y Performance and Cybertruck. However, this feature has been highly requested by owners for an extended period of time.

Tesla launched the Outlet Adapter in China last year:

You will need the Mobile Connector to operate the Outlet Adapter: the Outlet Adapter will plug into the main housing of the Mobile Connector, where the appropriate adapter to charge your vehicle will plug in.

It is rated for 120 volts and 20 amps, and has a max power rating of 2.4kW.

You can buy it here from Tesla for $80.

Tesla Roadster unveiling nears, and it will fly: The Information

Published

on

Tesla is nearing its long-awaited unveiling of the all-electric Tesla Roadster, a new report from The Information claims, as the company has said several times this year that the event would take place “soon.”

Now, it appears there is movement on Tesla’s end regarding when it will happen.

The report says that Tesla will unveil the Roadster as soon as this month with a SpaceX version that will utilize cold-gas thrusters to help the vehicle float for a short period of time. This is something CEO Elon Musk has talked about with the Roadster for years.

Additionally, due to the delays, Tesla explored “a variety of designs” for the Roadster, potentially planning to abandon the design it showed off for the first time in 2017 and adopting an entirely new aesthetic.

According to The Information, Tesla considered utilizing a repurposed Model S Plaid and even wanted to upgrade the look to something like a Lamborghini Countach.

Elon Musk teases Tesla Roadster unveiling once again

We’ve heard all of these things before, including teases about the date and how “soon” the Roadster will finally be ready to be shown off to the world (for the second time). Musk said that the event would occur in April, then May, then Chief Designer Franz von Holzhausen continued to say it would be coming “soon.”

We do expect to see the Roadster by the end of the year, and now with this new report swirling, it appears it could be sooner rather than later.

The wait has been incredibly long, but there is likely a good reason for it. Tesla’s desire to make the Roadster the craziest vehicle on the road was non-negotiable, and it likely took a lot of time and resources to develop and perfect into something that was safe and suitable for a vehicle like this.

Tesla finally got its Nevada Robotaxi Permit but with a few catches hard to miss

Nevada granted Tesla’s robotaxi permit, but capped the fleet at just ten vehicles for now.

Tesla has received its robotaxi permit in Nevada, more than two months after regulators closed the public comment period on the company’s application. News of the approval surfaced Wednesday night when Tesla investor and longtime company watcher Sawyer Merritt posted a copy of the interim order, and the Nevada Transportation Authority’s own carrier registry now lists the permit, AVNC Permit 002 under Docket 26-05015, as active for Tesla Robotaxi, LLC.

Tesla asked Nevada in June for authority to run up to 5,000 vehicles in Clark County within a year, however the permit the NTA issued is initially capping Tesla at ten fully autonomous vehicles and confines them to a defined geofence along the Las Vegas Strip corridor. Any expansion of that operating area, or any increase to the fleet size, requires the NTA’s approval first.

The order also sets rules that look more restrictive than what Tesla runs in Austin. Rides are barred on roads with posted speed limits above 45 miles per hour, pickups are off limits within a quarter mile of Harry Reid International Airport without separate authorization, and every vehicle has to carry visible “Robotaxi” markings while notifying riders before each trip that no one is driving. The order also requires “appropriate human supervision”, language that suggests Nevada isn’t ready to let Tesla offer the rides without a safety monitor that it has run in parts of Austin since January. As with standard protocol with robotaxi services, Tesla must report any accident, system failure, or vehicle that becomes stranded on a Nevada road within five business days.

Tesla is entering a market Nevada already knows well. Zoox, the Amazon owned robotaxi company, has run its own autonomous vehicle permit in the state since last year, building up to roughly 100 vehicles and 350,000 rides along the Strip. That history likely explains why the NTA started Tesla at ten cars rather than the fleet size the company asked for. The agency has a template for scaling a permit up once a company proves out its safety record.

Tesla’s Nevada application first surfaced in June, when the company filed for the permit alongside plans for a maintenance hub in southwest Las Vegas. The company has said it won’t meaningfully scale its robotaxi fleet anywhere until FSD v15 ships, expected in late 2026 or early 2027, which makes the ten vehicle cap less of a constraint today than it might look on paper. For now, Tesla has the legal right to start Nevada rides. Whether it starts before FSD v15 arrives is a separate question the permit doesn’t answer.
