The Arctic is experiencing disproportionately higher temperature increases compared to the rest of the planet, triggering a series of cascading effects. This rapid warming has profound implications for global climate patterns, human populations and wildlife.

The Copernicus Imaging Microwave Radiometer mission (CIMR) will provide measurements to decision makers with evidence of change and impact in the polar regions – with a focus on the Arctic.

The mission has the largest radiometer developed by ESA and will provide high-resolution measurements related to sea ice, the ocean, snow and ice-sheet surfaces. This will be crucial in understanding the evolution of the

An American spaceship attempting a lunar landing has been rescheduled to launch early Thursday, the second private-led effort this year after the first ended in dismal failure. Intuitive Machines, the Houston company leading mission "IM-1," hopes to become the first non-government entity to achieve a soft touchdown on the Moon and land the first US robot on the surface since the Apollo missi

I used to love rocket launches when I was younger. During every launch, I imagined what it would feel like to be an astronaut sitting in the spacecraft, listening to that final countdown and then feeling multiple gees push me up through the atmosphere and away from our blue marble. But as I learned more about the severe limitations of human spaceflight, I turned my attention to the oldest

On Earth, rocks and soil are weathered by wind and water, but what weathers surfaces on the Moon? New research investigates how ice might alter lunar soil in permanently shadowed lunar craters. The Moon is blanketed in a layer of material called regolith, made up of fragments of rock, soft lunar soil, and fines: particles less than 2 microns across (1 micron = 10-6 meter). Apollo-era astro

The stages that make up the central core of Europe's new rocket, Ariane 6, have left mainland Europe and are heading towards Europe's spaceport in French Guiana. Shipping across the Atlantic, the main stage and upper stage were loaded into the purpose-built hybrid sailing ship Canopee at the harbours of Bremen, Germany, and Le Havre, France. Canopee left the port of Le Havre carrying the l

Earth planning date: Friday, February 9, 2024: We are found Curiosity at full energy and ready to go this morning. And go we did! We are at a very interesting location with lots of textures in the rocks in front of us, and many features to spot in the walls around us. Geologists feasting time! And feast we did! I counted - between Mastcam, ChemCam, the Navcams, and MARDI almost 450 individ

The unique two thin rings around the Centaur Chariklo could be shaped by an even smaller satellite. Chariklo is a Centaur, which are small bodies similar to asteroids in size but to comets in composition, that revolve around the Sun in the outer Solar System, mainly between the orbits of Jupiter and Neptune. "Rings around minor planets have only been recently discovered, and only a small n

Ordinarily, planets in evolved planetary systems, such as the Solar System, follow stable orbits around their central star. However, many indications suggest that some planets might depart from their birthplaces during their early evolution by migrating inward or outward. This planetary migration might also explain an observation that has puzzled researchers for several years: the relatively low
