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

Published

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 Model Y L attracts crowds across China stores

The Tesla Model Y L is shaping up to be a big hit in China.

Tesla has officially rolled out the Model Y L, a six-seat variant of its best-selling SUV, across all showrooms in China, and it is getting a lot of attention from potential buyers.

Images and videos from Tesla stores in China show crowds of people checking out the recently released extended wheelbase all-electric crossover.

Model Y L details

The vehicle, which carries a starting price of RMB 339,000 ($47,180), went live in Tesla China’s configurator this week. Deliveries are scheduled to begin in September, and early media reviews have already been released following the lifting of an embargo.

Unlike a full model refresh, the Model Y L is positioned as a new variant within the existing Model Y lineup. It joins the five-seat rear-wheel drive (RWD) and long-range all-wheel drive (AWD) Model Y variants currently available in China.

The six-seat Model Y L features dual-motor all-wheel drive, a 0–100 km/h time of 4.5 seconds, and an 82.0-kWh battery pack from LG Energy Solution. Its CLTC-rated range reaches 751 km, the highest among Tesla’s Model Y trims.

So far, the reception to the Model Y L appears to be very warm, with photos and videos of stores in locations such as Shanghai and Shenyang showing numerous people checking out the recently released vehicle. Reports from industry watchers in China also suggest that Tesla received about 35,000 orders for the Model Y L on its first day of release.

Market backdrop

The timing of the Model Y L’s release comes as Tesla faces headwinds in China’s competitive SUV segment. Between January and July, Model Y retail sales in the country reached 202,257 units, a 17.15 percent decline compared to the same period last year, according to data cited by CNEVPost. It should be noted, however, that a good portion of this decline was due to the retooling of Tesla’s factories to make way for the new Model Y.

Despite the slowdown, the Model Y remains one of Tesla’s strongest performers globally. By introducing a higher-range, six-seat option, Tesla appears to be positioning the Model Y L as a way to boost demand and appeal to new buyers in a market that was previously only accessible to the much more expensive Model X.

Tesla Model Y L gets disappointingly far production date in the United States

Fans of the extended wheelbase six-seater in the United States are in for a long wait.

The Tesla Model Y L is making a lot of waves in the electric vehicle community, but fans of the extended wheelbase six-seater in the United States are in for a long wait.

This was, at least, according to Tesla CEO Elon Musk, who provided a disappointingly long timeline for the Model Y L’s production in the United States.

The Model Y L

The Model Y L has received near universal acclaim from electric vehicle enthusiasts and auto reviewers in China alike. Priced at just RMB 339,000 ($47,180) and fitted with a spacious and comfortable cabin, the Model Y L seemed destined to become a segment killer. And since the vehicle is also produced in Tesla’s existing Model Y lines, it seemed like the vehicle would be released worldwide soon. 

It was then no surprise that many Tesla community members were keen on asking if the Model Y L will be released in the United States anytime soon. Others also wondered why CEO Elon Musk was very quiet about the vehicle despite all the buzz it was generating. Eventually, Musk did share an update about the Model Y L, but it was not what many expected.

Elon Musk’s update

Amidst the conversations on X about the Model Y L, longtime FSD tester Whole Mars Catalog noted that Elon Musk would not be saying anything about the vehicle until its international release, likely because he would like to avoid an Osbourne Effect on the standard Model Y. Tesla’s sales today are still highly dependent on the standard Model Y, after all, as it is the company’s best-selling vehicle.

Musk responded to the FSD tester, stating that the Model Y L will not start production in the United States until the end of 2026. He also noted that the vehicle might not even make it in America at all, considering Tesla’s focus on self-driving. “This variant of the Model Y doesn’t start production in the US until the end of next year. Might not ever, given the advent of self-driving in America,” Musk wrote in his post.

Musk’s post was received with much disappointment from many X users, some of whom joked that the CEO was risking alienating families with three kids with his comments. The Model Y L, after all, is a legitimate family car that can comfortably seat six, and it seemed like a vehicle that Musk would prioritize considering his stance on people having bigger families. Of course, the CEO might still just be preventing an Osbourne Effect with his comments, but it’s difficult to deny that a 2026 U.S. production date for the Model Y L is still disappointing.

Tesla’s Elon Musk considers insane Cybertruck mod: ‘Maybe we should make this’

The Cybertruck won’t do what the video shows (at least not in our lifetime), but a very entry-level version of it could be developed.

Tesla CEO Elon Musk has teased what could potentially be the company’s next big project, and while it is likely many, many years away, it shows the company truly has its sights set on the craziest things the world has seen.

Musk shared a video created by Grok Imagine, the AI tool that is able to take images and turn them into videos, showing a Cybertruck flying above the clouds and buildings of what appears to be a very futuristic city.

There are also massive robots roaming around in the video, so it is obviously an illustration of what life could look like in several generations.

However, Musk, who does not shy away from some really optimistic projects and goals, shared the video on X and said, “Maybe Tesla should make this.”

What is depicted in the video is not what we’d see Tesla create anytime soon. However, the company could potentially engineer something to make the Cybertruck hover, as it plans to do with the Roadster.

Of course, this is likely a huge “if” considering the current state of the car industry. Vehicles are becoming more advanced with every passing day as companies like Tesla, Waymo, and others are working to sort out things like autonomous and driverless travel.

Tesla has been working on somewhat of a similar idea with the Roadster, a vehicle that has been delayed on several occasions because of Musk’s spectacular imagination. Earlier this year, Tesla’s Chief Designer, Franz von Holzhausen, revealed Musk wanted to push the limits of that vehicle even more.

The new Tesla Roadster will be able to fly: Elon Musk

It seems it could be on the way soon, considering Tesla has teased an “epic” demo for the car, which could come before the end of the year.

Tesla has been working to make the Roadster hover, using SpaceX cold gas thrusters. It will also utilize these for what could be an incredibly fast 1.1-second 0-60 MPH acceleration rate that has been teased countless times.

This project that Musk is teasing with the Cybertruck is likely one that we will not see in our lifetimes. However, this is just one example of the outlandish ideas Musk continues to tease for Tesla in the future.
