Following preparatory activities and a stringent process ESA Member States today formally selected Harmony for implementation as the tenth Earth Explorer mission within the FutureEO programme. This unique satellite mission concept is, therefore, now set to become a reality to provide a wealth of new information about our oceans, ice, earthquakes and volcanoes - which will make significant contri

The Jinping Underground Nuclear Astrophysics (JUNA) collaboration has reported a recent direct measurement of the cross section of a crucial stellar neutron source reaction, 13C(a,n)16O. The study was published in Physical Review Letters on September 23. By achieving the most accurate cross sectional measurement of this reaction at astrophysical energies so far, the study has resolved long

The exploration era for the new James Webb Space Telescope (JWST) is getting hot - volcanically hot. A multidisciplinary group of Cornell researchers has modeled and synthesized lava in the laboratory as the kinds of rock that may form on far-away exoplanets. They developed 16 types of surface compositions as a starter catalog for finding volcanic worlds that feature fiery landscapes and oceans

A Curtin-led research team has found asteroid impacts on the Moon millions of years ago coincided precisely with some of the largest meteorite impacts on Earth, such as the one that wiped out the dinosaurs. The study also found that major impact events on Earth were not stand-alone events, but were accompanied by a series of smaller impacts, shedding new light on asteroid dynamics in the i

What does the subsurface of Mars' northern lowlands have in common with a French mille crepe cake? They both consist of a number of layers, according to the latest findings by China's Zhurong Mars rover published in the journal Nature on Monday. The discovery showed that the evolution of the Martian surface environment is more varied and complex than previously anticipated, experts said. L

Once upon a time - early 2013 - there was a small corner room in the Flight Projects building at JPL where the walls and windows were coated in pages and pages of paper. These pages contained the facts and arguments being assembled by the Mars 2020 Science Definition Team, who were asking: what must the next rover to Mars do? We rearranged those pages over and over during the next few mont

About two billion years ago, an impactor hurtled toward Earth, crashing into the planet in an area near present-day Johannesburg, South Africa. The impactor-most likely an asteroid-formed what is today the biggest crater on our planet. Scientists have widely accepted, based on previous research, that the impact structure, known as the Vredefort crater, was formed by an object about 15 kilo

British Earth Observation company, Satellite Vu has signed a second SpaceX launch contract for their second satellite, doubling their thermal data collection capacity, faster than planned, amidst rising climate concerns. The deal will see Satellite Vu's unique Mid-wave Infrared (MWIR) imaging satellite launched into Sun-synchronous orbit (SSO) aboard a Falcon 9 rocket in early 2024. The sa

During spring and summer, as the air warms up and the sun beats down on the Greenland Ice Sheet, melt ponds pop up. Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image.
