The UPV/EHU prepares to analyse material from Mars using non-destructive analytical methods
The UPV/EHU’s IBeA research group, which includes experts in Raman spectroscopy, is currently analyzing meteorites with the aim of developing non-destructive analytical strategies for upcoming explorations of Mars materials by the Perseverance rover, shortly due to arrive at the red planet. The strategies will also be used to examine materials collected by the Rosalind Franklin rover and returned to Earth following…
Evidence of water movement found in meteorites that only recently fell to Earth
A team of researchers affiliated with institutions in Australia, the U.S. and France has found evidence of relatively recent water movement in meteorites that only recently collided with the Earth. In their paper published in the journal Science, the group describes their study of carbonaceous chondrite (CC) meteorites that landed on the surface of the Earth within the past century and…
An Asteroid the Size of a Dwarf Planet Is Lurking In Our Solar System
Long-time Slashdot reader fahrbot-bot summarizes an article from LiveScience: There’s a giant asteroid somewhere out in the solar system, and it hurled a big rock at Earth. The evidence for this mystery space rock comes from a diamond-studded meteor that exploded over Sudan in 2008. NASA had spotted the 9-ton (8,200 kilograms), 13-foot (4 meters) meteor heading toward the planet well…

This asteroid just skimmed Earth’s atmosphere
The asteroid – 2020 VT4 – is estimated to be between 16 and 36 feet (5-11 meters). It skimmed the top of our atmosphere on Friday, November 13, 2020. Astronomers spotted it one day later. Source: https://earthsky.org/space/asteroid-2020-vt4-skimmed-atmosphere-fri-nov-13-2020…
Hubble telescope reveals asteroid Psyche’s rusty surface
Scientists already had Psyche classified as a metallic asteroid, but new observations with the Hubble telescope reveal its rusty surface and provide scientists with a unique view into what Earth-like planets are like during their formation.

A NASA Mission Is About To Capture Carbon-Rich Dust From a Former Water World
sciencehabit writes: OSIRIS-REx is ready to get the goods. On 20 October, after several years of patient study of its enigmatic target, NASA’s $800 million spacecraft will finally stretch out its robotic arm, swoop to the surface of the near-Earth asteroid Bennu, and sweep up some dust and pebbles. The encounter, 334 million kilometers from Earth, will last about 10 seconds….
New insights into the origin of diamonds in meteorites
Scientists have offered new insights into the origin of diamonds in ureilites (a group of stony meteorites). These diamonds most likely formed by rapid shock transformation from graphite (the common low-pressure form of pure carbon) during one or more major impacts into the ureilite parent asteroid in the early solar system.
