China to Launch Lunar Lighting in Outer Space

China is planning to launch its own 'artificial moon' by 2020 to replace streetlamps and lower electricity costs in urban areas, state media reported Friday.

According to China Daily, "illumination satellites" will shine in tandem with the real moon over Chengdu, a city in southwestern Sichuan province, but eight times brighter.

The first man-made moon will launch from Xichang Satellite Launch Center in Sichuan, with three more to follow in 2022 if the first test goes well, said Wu Chunfeng, head of Tian Fu New Area Science Society, the organization responsible for the project.

Though the first launch will be experimental, the 2022 satellites "will be the real deal with great civic and commercial potential," he said in an interview with China Daily.

By reflecting light from the sun, the satellites could replace streetlamps in urban areas, saving an estimated 1.2 billion yuan ($170 million) a year in electricity costs for Chengdu, if the man-made moons illuminate an area of 50 square kilometers.

The extraterrestrial source of light could also help rescue efforts in disaster zones during blackouts, he added.

As China's space program races to catch up with that of the United States and Russia, a number of ambitious projects are in the pipeline, including the Chang'e-4 lunar probe -- named after the moon goddess in Chinese mythology -- which aims to launch later this year. If it succeeds, it will be the first rover to explore the "dark side" of the moon.

China is not the first country to try beaming sunlight back to Earth. In the 1990s, Russian scientists reportedly used giant mirrors to reflect light from space in an experimental project called Znamya or Banner.

Chengdu's artificial moon project was announced by Wu at an innovation and entrepreneurship conference in Chengdu on October 10.

In addition to Tian Fu New Area Science Society, other universities and institutes, including the Harbin Institute of Technology and China Aerospace Science and Industry Corp, are involved in developing Chengdu's illumination satellites.

Scientists have uncovered the mummified remains of cheetahs from caves in northern Saudi Arabia.

The remains range from 130 years old to over 1,800 years old. Researchers excavated seven mummies along with the bones of 54 other cheetahs from a site near the city of Arar.

Mummification prevents decay by preserving dead bodies. Egypt's mummies are the most well-known, but the process can also happen naturally in places like glacier ice, desert sands and bog sludge.

The new large cat mummies have cloudy eyes and shriveled limbs, resembling dried-out husks.

“It’s something that I’ve never seen before,” said Joan Madurell-Malapeira with the University of Florence in Italy, who was not involved with the discovery.

Researchers aren’t sure how exactly these new cats got mummified, but the caves’ dry conditions and stable temperature could have played a role, according to the new study published Thursday in the journal Communications Earth and Environment.

They also don't know why so many cheetahs were in the caves. It could have been a denning site where mothers birthed and raised their young.

Scientists have uncovered the rare mummified remains of other large cats, including a saber-toothed cat cub in Russia.

It's uncommon for large mammals to be preserved to this degree. Besides being in the right environment, the carcasses also have to avoid becoming a snack for hungry scavengers like birds and hyenas.

Cheetahs once roamed across most of Africa and parts of Asia, but now live in just 9% of their previous range and haven't been spotted across the Arabian Peninsula for decades. That’s likely due to habitat loss, unregulated hunting and lack of prey, among other factors.

In a first for naturally mummified large cats, scientists were also able to peek at the cheetahs' genes and found that the remains were most similar to modern-day cheetahs from Asia and northwest Africa. That information could help with future efforts to reintroduce the cats to places they no longer live.

Lindsey Vonn may be dominating World Cup downhills at 41, but even the US speed queen is not immune to missing equipment.

Vonn took to social media on Thursday with an unusual plea after losing a ski pole in Tarvisio, Italy, ahead of this weekend's World Cup event.

"Someone took ‌my pole ‌in the parking ‌lot ⁠today in ‌Tarvisio. If you have seen it, please respond to this. Thank you," Vonn wrote on X, posting a photo of the matching pole complete with her initials on the ⁠hand strap.

Vonn, a favorite for the speed events ‌at next month's Milano-Cortina ‍Olympics, retired ‍from the sport in 2019 and ‍had a partial knee replacement in April 2024 but returned to competition later that year and has been enjoying a fairy-tale comeback that has defied age and expectation.

Already the oldest ⁠World Cup winner of all time, Vonn continued her astonishing, age-defying form with a downhill victory in Zauchensee, Austria last week.

That triumph marked Vonn's fourth podium from four downhills this season, cementing her lead in the World Cup standings and her status as the woman to ‌beat at next month's Olympics.

Four International Space Station (ISS) crewmembers splashed down in the Pacific Ocean early Thursday, video footage from NASA showed, after a medical issue prompted their mission to be cut short.

American astronauts Mike Fincke and Zena Cardman, Russian cosmonaut Oleg Platonov and Japan's Kimiya Yui landed off the coast of San Diego about 12:41 am (0841 GMT), marking the first-ever medical evacuation from the ISS.
