Until recently, geochronologist Li Xian-Hua’s research focused on molten rocks on Earth. But when a Chinese spacecraft delivered the country’s first rocks from the Moon in December 2020, Li pivoted to study them. “I’m a new person working on extra-terrestrial rocks,” says Li, who is based at the Institute of Geology and Geophysics (IGG) at … Read more
China’s first Mars rover reveals how weather and ancient water changed the surface of the largest impact basin on Mars. China’s Zhurong rover landed in the Utopia Planitia, a 2,000-miles-wide (3,300 kilometers) basin in the Northern Hemisphere of Mars, in May 2021. Since then, the rover has been studying local geology, chemical composition of rocks, … Read more
Early Earth is often described as ‘Hadean’ for good reason. Arising from the ashes of a collision that gave us our Moon, the primordial eon was characterized by hellish heat trapped beneath a thick blanket of carbon dioxide and water vapor. Strangely those conditions should have been inhospitable for far longer than they were. … Read more
The water that Earth has may have been here since the planet formed, and not delivered later by collisions with icy comets, a new study finds. The research analyzed moon rocks brought to Earth by the Apollo program and may shed light on our planet’s earliest days. Although more than 70% of Earth’s surface is … Read more
We don’t know how life emerged on Earth, but one thing is certain: life as we know it on our planet wouldn’t exist without the water that wraps around the surface, runs in rivulets, and falls from the sky. Our planet is the only one known to have life, and the only one on … Read more
An artificial intelligence program suggests there may be hundreds of thousands of meteorites left for scientists to discover on the icy fields of Antarctica and reveals what may be the most likely places to unearth them, a new study finds. Nearly two-thirds of all meteorites recovered on Earth originate in Antarctica. The cold, dry nature … Read more
A quick twist and shake relieved NASA’s Perseverance rover on Mars of the last two pebbles clogging its sampling system. The trouble began during the rover’s sixth Red Planet rock sample, on Dec. 29. Pebbles got stuck along the rover’s bit carousel, which passes rock samples into the spacecraft’s internal handling system for processing. After … Read more
It’s been half a century since the Apollo missions returned from the Moon, and yet the lunar samples they brought home continue to baffle us. Some of these rocks are more than 3 billion years old and appear to have been formed in the presence of a strong geomagnetic field, like the one on Earth. … Read more
Molecules containing carbon atoms, called organics, have been found all over Mars and could hypothetically have been formed by living organisms, but it seems they were not Space 13 January 2022 By Leah Crane The Allan Hills 84001 meteorite NASA/JSC/Stanford University Organic compounds – those containing carbon atoms – found all over Mars were produced … Read more
There’s a new explanation for the moon’s former magnetic field, and it involves 60-kilometre-wide slabs of rock sinking through the lunar mantle Space 13 January 2022 By Matthew Sparkes The moon once had a relatively strong magnetic field NASA Moon rocks collected by the Apollo missions sparked a mystery because they showed signs of having formed … Read more
