As the planet warms, many parts of the Earth system are undergoing large-scale changes. Ice sheets are shrinking, sea levels are rising and coral reefs are dying off.

While climate records are being continuously broken, the cumulative impact of these changes could also cause fundamental parts of the Earth system to change dramatically. These ‘tipping points’ of climate change are critical thresholds in that, if exceeded, can lead to irreversible consequences.

The Copernicus Anthropogenic Carbon Dioxide Monitoring (CO2M) mission will be the first satellite mission to measure how much carbon dioxide is released into the atmosphere through human activity.

CO2M isn't just a mission; it's a crucial step in our commitment to understanding and mitigating climate change. It will offer unprecedented precision in monitoring carbon dioxide emissions from the combustion of fossil fuel at national and regional scales.

Its data will provide the EU with a unique and independent source of information to assess the effectiveness of policy measures and to track their impact towards decarbonising Europe ahead of the

The Space Development Agency (SDA), a key player in the United States Department of Defense's strategic initiatives, recently announced a significant milestone in space communication technology. In a series of demonstrations held from November 21-27, 2023, the SDA successfully executed the first-ever network entry using the Link 16 system from low Earth orbit (LEO) to a series of terrestrial rec

Five years ago, HawkEye 360 Inc., a trailblazer in space-based radio frequency (RF) data and analytics, embarked on an ambitious journey with the launch of its Pathfinder satellite cluster. On December 3, 2018, the three Pathfinder satellites were successfully launched aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California, marking a significant milestone in commercial spac

As astrophysics technology and research continue to advance, one question persists: is there life elsewhere in the universe? The Milky Way galaxy alone has hundreds of billions of celestial bodies, but scientists often look for three crucial elements in their ongoing search: water, energy and organic material. Evidence indicates that Saturn's icy moon Enceladus is an 'ocean world' that contains

Earth planning date: Monday, December 4, 2023: It is not unusual for things to not quite go according to plan when commanding a robotic rover more than 370,000,000 km (233,000,000 miles) away on Mars. Today was one of those days. Our planned weekend activities, including finishing up analyses of the Sequoia drill hole and fines, did not make it onboard Curiosity. However, the team is used

NASA's Psyche spacecraft is on a roll. In the eight weeks since it left Earth on Oct. 13, the orbiter has performed one successful operation after another, powering on scientific instruments, streaming data toward home, and setting a deep-space record with its electric thrusters. The latest achievement: On Monday, Dec. 4, the mission turned on Psyche's twin cameras and retrieved the first images

Preparations for a safe landing on Earth, such as finding the most even terrain and equipping the appropriate landing gear, are also crucial for Mars missions. Thus, landing a rover on Mars requires careful mapping and planning well before a rover's descent begins. Scientists are working to create accurate 3D surface maps, known as digital terrain models, of the planet by compiling mosaics
