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:

Elon Musk has a crazy prediction about AI in two years

Published

Elon Musk is, in many respects, one of the biggest and most influential figures in modern-day artificial intelligence.

Given that Tesla, SpaceX, and xAI are all looked at in their respective fields as leaders to an extent, each of them has a heavy influence on the future of AI, even though two of them are not thought of, at face value, as AI companies.

Musk has grand expectations for what is to come with AI, not only as a form of assistance to make human lives easier, but to make humans multiplanetary and solve some of the biggest issues that face us today. But even he is astounded by AI’s pace of progress.

He believes that in two years, AI will be so mind-blowing it might be unrecognizable.

This progress can be seen in a variety of ways, but perhaps the most popular way people have shown AI’s progress, especially on social media, is through an incredibly arbitrary way of watching Will Smith eat spaghetti:

This is a great way to show people how AI is improving, especially from a perspective that examines how it can manufacture images and video from prompts. AI is an incredibly complex concept, however, and it goes much deeper than Will Smith eating Italian food.

Musk’s most widely adopted method of AI is likely Tesla Full Self-Driving, which impacts millions of people as they utilize it to increase safety with their travel. Musk has routinely pushed incredibly aggressive timelines for self-driving, especially unsupervised.

Perhaps this perspective is why he feels that things will be solved in a timeframe that is much more aggressive than most of us would think. Regardless, the progress of AI is moving fast, and it seems that Musk’s expectations for it could be high.

But if it can actually achieve full-length motion pictures and even more realistic production value, it will be hard to distinguish between reality and AI very soon.

Tesla just built it 10 millionth car

Tesla just officially confirmed it has built its 10 millionth car, a major milestone for the company that started producing sustainable electric powertrains less than two decades ago.

In that time, Tesla has truly revolutionized the automotive industry, disrupting the idea of what a car should be, how it should be fueled, and how it truly impacts day-to-day life.

Tesla achieved this feat across four production facilities: the Fremont Factory in Fremont, California, Gigafactory Shanghai in China, Gigafactory Berlin in Germany, and Gigafactory Texas in Austin, Texas.

The 10 millionth vehicle was a Diamond Black Model Y.

Over the course of the past roughly 18 years, Tesla has evolved its lineup from a sporty sedan built on a Lotus body to a lineup of various body styles, performance metrics, and other characteristics that make each one unique.

This is an incredible achievement for a company that is young compared to what it goes up against. When Tesla entered the automotive market, Ford, GM, and Stellantis widely dominated the playing field. Since then, Tesla has caused such a disruption that these three massive brands had to scramble to create EV projects of their own.

Despite their best efforts, they have not been able to match the prowess or the effectiveness of Tesla. They are all reliant on Tesla’s charging infrastructure, their software is inferior, and their self-driving projects are elementary in comparison.

Tesla felt its fair share of growing pains over the years as well. As recent at 2019, there were complaints about build quality, paint quality, and overall luxuriousness. These things have all been improved upon through the company’s maturity, and these strides in quality have led to this 10 million vehicle production achievement, something that other small-and-scrappy EV makers will hope to accomplish one day.

SpaceX scores another massive Pentagon deal to support military satellites

Published

SpaceX just picked up another $1.6 billion from the Pentagon, with the U.S. Space Force awarding two task orders worth $1.6 billion to fly 18 Falcon 9 missions from Vandenberg Space Force Base in California through the end of 2027. The launches will carry satellites for the Space Based Sensing and Targeting portfolio, a set of programs meant to help the military detect and track airborne threats and relay that information across forces in near real time.

The award falls under National Security Space Launch Phase 3 Lane 1, the Space Force’s faster, commercial style procurement track for missions that do not require the military’s most demanding certification process. It is also the largest single order publicly disclosed under that program so far, and the first task order issued since the Space Force nearly tripled Lane 1’s contract ceiling from $5.6 billion to $17 billion on July 17.

SpaceX to become America’s Military data backbone for missiles, drones, and warfighters

Eric Zarybnisky, the Space Force’s acting portfolio acquisition executive for space access, said the entire process, from identifying the requirement to signing the contract, took about two months, including a month set aside for companies to prepare proposals.

SpaceX is not just launching these satellites. It already holds the contracts to build two of the programs within the same portfolio, $4.16 billion for the Space Based Airborne Moving Target Indicator system and $2.29 billion for the Space Data Network Backbone, which Teslarati covered in May. That means SpaceX is now responsible for both building key pieces of the military’s next generation sensing network and getting them into orbit.

With this latest award, SpaceX’s Pentagon contract total for 2026 alone tops $8 billion, adding to a defense portfolio that already includes the Golden Dome missile defense software group SpaceX joined in April and a string of GPS launches it inherited after ULA’s Vulcan rocket ran into a booster anomaly, which we detailed in March.

Lane 1’s vendor pool technically includes seven companies: SpaceX, ULA, Blue Origin, Rocket Lab, Stoke Space, Impulse Space, and Relativity Space. In practice, SpaceX remains the only provider with the combination of launch cadence, flight proven Falcon 9 hardware, and West Coast infrastructure to support a campaign requiring roughly one Vandenberg launch a month for the next year and a half.

Some lawmakers have flagged the growing concentration of national security launches with one company as a risk worth watching. For now, the Space Force keeps backing SpaceX, with it being the company that shows up ready to launch.
