Tracking ice lost from the world’s glaciers, ice sheets and frozen land shows that Earth is losing ice at an accelerating rate. Monitoring the cryosphere is crucial for assessing, predicting and adapting to climate change.

The Copernicus Polar Ice and Snow Topography Altimeter (CRISTAL) mission will provide a full picture of the changes taking place in some of the most inhospitable regions of the world. It will carry – for the first time – a dual-frequency radar altimeter, and microwave radiometer, that will measure and monitor sea-ice thickness, overlying snow depth and ice-sheet elevations.

These data will support maritime

Playing a huge role in moderating the climate, oceans are fundamental to the functioning of our planet. Understanding more about how seawater temperatures are rising and how oceans are absorbing excess atmospheric carbon dioxide, as well as knock-on issues such as ocean acidification, is key for understanding climate change and for taking effective action.

A recent scientific paper highlights just how satellites are becoming increasingly important in providing unique information on ocean health to guide climate mitigation and adaptation efforts.

A company from Texas is poised to attempt a feat that until now has only been accomplished by a handful of national space agencies, but could soon become commonplace for the private sector: landing on the Moon. If all goes to plan, Houston-based Intuitive Machines will guide its spaceship named Odysseus to a gentle touchdown near the lunar south pole on Thursday at 2249 GMT, then run experim

The year 2024 promises to be a busy one for American Moon landings, all under a new partnership between NASA and the space industry. A first attempt under the Commercial Lunar Payload Services (CLPS) initiative ended in disappointing failure last month, but a second, led by Houston-based Intuitive Machines, will attempt on Thursday to return the United States to Moon for the first time in fi

Further embracing the New Space era, ESA is to develop two new Scout satellites: NanoMagSat and Tango. NanoMagSat will measure Earth’s magnetic field to help assess space weather hazards and continue on from ESA’s current Swarm mission. Tango will measure greenhouse-gas emissions from human activity and complements the upcoming Copernicus Carbon Dioxide Monitoring mission and the Sentinel-5 mission, as well as the current Sentinel-5P mission.

In a recent gathering at the Air and Space Forces Association's Warfare Symposium, leaders from the U.S. Space Force (USSF) and U.S. Space Command (USSPACECOM) cast a spotlight on the pivotal role of partnerships in countering the burgeoning threats in space, particularly from global competitors like China and Russia. Lt. Gen. Douglas Schiess, commander of U.S. Space Forces - Space, and Lt. Gen.

In a significant development for satellite technology, Voyager Space (Voyager), a pioneering force in global space exploration, has been selected by Millennium Space Systems (Millennium), a Boeing Company, to produce a series of advanced star trackers. This collaboration underscores a crucial step forward in enhancing the capabilities of Millennium's small satellite constellations, with phased d

In a groundbreaking study that revisits the foundational principles of general relativity and the nature of cosmic objects, theoretical physicists from Goethe University Frankfurt have proposed a revolutionary concept known as "nestars." This new theory, which builds upon the foundation laid by the concept of gravitational condensate stars, or gravastars, suggests the existence of a gravastar wi
