China launches mission to get asteroid samples

Yahoo29-05-2025

China on Thursday launched its first space mission to retrieve samples from a nearby asteroid and conduct research back home, the Xinhua state news agency reported.
A successful completion of the mission could make China, a fast-growing space power, the third nation to get hold of the pristine asteroid rocks.
The mission began with a Long March-3B rocket carrying the Tianwen-2 probe blasting off from the Xichang launch site in southwestern Sichuan province at 1:31 a.m. local time (1731 GMT/UTC).
It took 18 minutes for the Tianwen-2 spacecraft to enter a transfer orbit for asteroid 2016HO3, the China National Space Administration (CNSA) said, according to Xinhua.
"The spacecraft unfolded its solar panels smoothly, and the CNSA declared the launch a success," the news agency wrote.
Tianwen-2 is scheduled to arrive at the asteroid in July 2026 and shoot a capsule packed with rocks back to Earth for a landing in November 2027.
The asteroid was discovered in 2016 by scientists in Hawaii and is roughly 40 to 100 metres (130-330 feet) in diameter and revolves relatively close to Earth.
The Tianmen-2 spacecraft is also tasked with exploring the comet 311P, according to the country's space agency.
China has swiftly made its mark with its expanding space program.
In the past few years, it has poured billions of dollars into its space program to achieve what President Xi Jinping describes as the country's "space dream."
China already has its own space station, and in recent years, it has managed to send robots to the far side of the moon. It is now planning to send humans to the lunar surface by 2030.

Massive Asteroid Could Hit the Moon, Here's How It Would Impact Earth

There's the good (Earth is no longer at risk of a direct hit from an asteroid dubbed 2024 YR4); the bad (shrapnel could cause extensive damage to orbiting satellites); and the ugly (odds of the asteroid hitting the moon have now increased). A Cornel University study submitted to the American Astronomy Society Journals concludes that, while Earth is no longer in danger of a direct asteroid hit, odds of the asteroid hitting the moon have increased -- from 3.8 percent to 4.3 percent. If those odds play out, NewScientist reports that a direct impact could "shower Earth with a cloud of satellite-destroying shrapnel." The study concluded that, if the asteroid hits the moon, the orbiting satellites could suffer decades worth of damage in a matter of just a few days. Dr. Paul Wiegert, a professor of astronomy at the University of Western Ontario who spearheaded the study, told NewScientist that the study concluded the asteroid could hit the moon at a whopping 29,000 miles per hour. The impact would then create a blast crater just over a half-mile wide, which would make it the largest lunar impact in the last 5,000 years. YR4, an asteroid that's the size of a building, was first discovered in December 2024. Astronomers initially predicted the asteroid would hit Earth on Dec. 23, 2032, and it would have enough power decimate an entire city. But astronomers now say that that science is telling them the asteroid will most likely miss Earth. But our planet is not exactly out of the woods. Astronomers say that, if the asteroid hits the moon, the planet's gravity would siphon upwards of 10 percent of the debris back down to Earth. 'Intuitively, the Earth is actually quite a small target when seen from the moon, and so your intuition is that not very much material would actually hit the Earth," the astronomy professor Wiegert told NewScientist, "but it turns out that the Earth's gravity can focus that material under certain conditions." Perhaps a problem to worry about seven years from now. Massive Asteroid Could Hit the Moon, Here's How It Would Impact Earth first appeared on Men's Journal on Jun 20, 2025

Huawei Patents Solid-State Battery That Would Let You Road Trip From Miami To Maine On A Single Charge

Toyota is currently working on solid-state batteries it says will allow it to build 900-mile EVs, but while many would call that overkill, dads across the country know it isn't enough. We need more range if EVs are ever going to be good enough for a proper road trip, and if Huawei can deliver on its latest solid-state battery patent, we may almost be there. That's because it offers more than 1,800 miles of range on a single charge, CarNewsChina reports. For context, that's enough range to drive from Miami, Florida, to Bangor, Maine, without stopping. That said, China's range estimates are even more generous than Europe's, which means you may only get 1,200 or 1,300 miles out of a battery like that in the United States. Pitiful, I know. At that point, there's basically no reason to even bring your external catheter on a road trip. Not that the U.S. would allow Chinese battery tech to be sold here in the first place or invest in catching up. Our EV tech will stay generations behind China's, and we will like it. From the sound of it, the real value in this patent is the battery's energy density: The patent outlines a solid-state battery architecture with energy densities between 400 and 500 Wh/kg, potentially two to three times that of conventional lithium-ion cells. The filing also details a novel approach to improving electrochemical stability: doping sulfide electrolytes with nitrogen to address side reactions at the lithium interface, a long-standing obstacle to the commercialisation of sulfide-based batteries. Huawei's design aims to boost safety and cycle life by mitigating degradation at this critical junction.

That would require an absolutely absurd amount of power, but it isn't like companies in China aren't working on that, too. BYD has already shown off a Megawatt charger that's capable of adding 250 miles of range in about five minutes. Early versions would also likely cost a small fortune, though, and it's also hard to see how practical Megawatt charging would be in the remote areas where people might actually use it. But while BYD does actually plan to build at least some of those Megawatt chargers, don't be surprised if Huawei's 1,800-mile solid-state battery ends up being more of a tech demonstration than anything else. Instead, it seems much more likely that the batteries that will ultimately make their way into production cars will be smaller and therefore lighter. A battery that's a third the size of the 1,800-mile battery would still offer more than enough range for a road trip while also drastically reducing weight. Considering how heavy EV batteries are — the battery in the Hummer EV weighs nearly 3,000 pounds — if there's one thing EVs need, it's less weight. So while Huawei's 1,800-mile battery is still theoretical for now, it's still cool to see battery tech advancing to the point where, in a few years, we may see long-range EVs that weigh about the same as gas-powered cars. At least in other countries outside the U.S., since Republicans have decided they'd rather just turn us into a technological backwater. Want more like this?
