NASA confirms the Sun’s new solar cycle; Moon and Mars missions will have to adapt

Published

on

NASA just announced that our Sun began a new solar cycle this year – its 25th to be exact – after reaching a solar minimum in December 2019. Solar weather activity is now expected to increase for the next five years until reaching a maximum in July 2025. With several space missions planned during that time frame for both the Moon and Mars, the Artemis program, in particular, involving astronauts on board, extra preparation and consideration will have to be made to weigh the impact of the increasing radiation events.

“Space weather predictions are…critical for supporting Artemis program spacecraft and astronauts,” NASA’s announcement detailed. “Surveying this space environment is the first step to understanding and mitigating astronaut exposure to space radiation.”

Solar activity is tracked by agencies around the world by counting the number of sunspots (black spots) that appear on the Sun. Each one is an indicator of some type of high-energy activity such as solar flares or coronal mass ejections, and their appearance means a large amount of Sun material has been ejected into space. This material can cause disruptions on Earth, in orbit, or on anything in the deep space region nearby our star. Satellites in particular have to cope with solar interruptions frequently, although algorithms and engineering tend to mitigate much notice from a consumer standpoint.

While the Artemis mission will certainly have to take on the new challenge of a Sun that’s becoming more and more active as time goes on, solar cycles aren’t something new to NASA’s human spaceflight program.

“As we emerge from solar minimum and approach Cycle 25’s maximum, it is important to remember solar activity never stops; it changes form as the pendulum swings,” explained Lika Guhathakurta, solar scientist at the Heliophysics Division at NASA Headquarters in Washington, in the solar cycle announcement. “There is no bad weather, just bad preparation… Space weather is what it is – our job is to prepare,” added Jake Bleacher, chief scientist for NASA’s Human Exploration and Operations Mission Directorate at the agency’s Headquarters.

When astronauts are orbiting the Earth, our planet’s magnetic field protects them from being directly hit by the majority of solar ejections; however, once outside that protective bubble and on their way to another deep space or lunar destination, things can be very dangerous. Radiation issues are often discussed when it comes to human space exploration, but scientists don’t seem to be short of ideas on how to handle it.

SpaceX CEO Elon Musk, for example, has proposed passengers en route to Mars using water as shielding. During a solar flare event, all on board would move to a part of the Starship where the liquid was being stored and essentially use it like a basement during bad weather. Given that SpaceX plans to deal with radiation in the longer term via Mars colonization, there may be plenty of other developments coming from the rocket launch (and landing) company in the near future.

Aside from the scientists watching and studying the Sun’s solar activity, the European Space Agency currently has a space probe in orbit around our star. The spacecraft has been sending back the closest pictures of the Sun we’ve ever seen, and a few new features have been observed such as ‘campfires.‘ The probe’s overall mission involves studying and understanding the Sun’s solar cycles and hopefully make space weather prediction akin to the kind of meteorology we have on Earth.

“Just because it’s a below-average solar cycle, doesn’t mean there is no risk of extreme space weather,” Doug Biesecker, panel co-chair and solar physicist at NOAA’s Space Weather Prediction Center (SWPC) in Boulder, Colorado, commented. “The Sun’s impact on our daily lives is real and is there. SWPC is staffed 24/7, 365 days a year because the Sun is always capable of giving us something to forecast.”

NASA held a live-streamed conference discussing the solar cycle announcement which you can watch below:

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.
