You may already know the legend of King Tutankhamen’s space dagger – an iron weapon forged from the rock of meteorites, and entombed with the ancient Egyptian pharaoh. Now a new study has revealed more details about this most fascinating and mysterious of artifacts. A thorough chemical analysis involving high-resolution photography and X-rays has … Read more
Pieces of rock from the asteroid Ryugu splashed down on Earth in 2020. Now, scientists studying the samples are revealing the asteroid’s true nature. Ryugu is a near-Earth asteroid that Japan visited with its Hayabusa2 spacecraft. The craft launched in 2014, arrived at the space rock in 2018 and in December 2020 dropped off a … Read more
A mountain-sized mass of igneous rock beneath the coast of southern Japan could be acting as a sort of magnet or lightning rod for huge earthquakes. According to a new 3D visualization of the feature, known as the Kumano Pluton, the tectonic energy from megaquakes seems to be diverted to several points along its side. … Read more
A suspected Martian underground lake is probably volcanic rock masquerading as water, according to a new study. In 2018, researchers found evidence that the Red Planet’s southern pole might have water beneath it. The possible water signature was first interpreted from radar observations made by Mars Express, a European Space Agency spacecraft. But a new … Read more
Radar images of Mars’s southern ice cap indicated that there could be a lake there – but a new set of simulations hints that it could be volcanic rock instead Space 24 January 2022 By Leah Crane The icy cap over Mars’s south pole, photographed by Mars Express ESA/DLR/FU Berlin / Bill Dunford There may … Read more
NASA’s Perseverance rover managed to spit out pieces of rock that had been blocking its Mars-sampling gear since late December. Although the un-choking procedure hadn’t been previously tested, the engineers on the Mars mission found it was rather “straightforward,” the team said in an earlier blog post. It involved pointing the drill containing a clogged … 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
A small pile of pebbles is clogging up the Perseverance Mars rover’s operations. The rover, which is collecting rock samples for eventual return to Earth, began to struggle on Dec. 29, after extracting a core from a rock the mission team nicknamed “Issole.” According to a NASA blog, the problem occurred in the device that transfers … Read more
To date, we’ve found over a hundred precious Mars rocks that have travelled from the red planet and landed on Earth at some point. Among those, specimen ALH84001 might well be one of the most enigmatic. This meteorite fragment was picked up during a snowmobile ride in the ice field of Alan Hills in Antarctica … 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
