More than 700 imaging satellites are orbiting the earth, and every day they beam vast oceans of information - including data that reflects climate change, health and poverty - to databases on the ground. There's just one problem: While the geospatial data could help researchers and policymakers address critical challenges, only those with considerable wealth and expertise can access it. No

The Missile Defense Agency-developed Joint Track Management Capability (JTMC) and Open Systems Gateway (OSG) linked multiple sensor and fire control systems from multiple services into one integrated network during a July 15 flight test at White Sands Missile Range, New Mexico. The integration led to the successful engagement of a cruise missile target by an Army Patriot Advanced Capabilit

A dust storm that engulfed the entire Red Planet in 2018 destroyed a vortex of cold air around the Martian south pole and brought an early spring to the hemisphere. By contrast, the storm caused only minor distortions to the polar vortex in the northern hemisphere and no dramatic seasonal changes. Dr Paul Streeter of The Open University's Faculty of Science, Technology, Engineering and Mathemati

A team at the Natural History Museum (NHM), London is paving the way for future rovers to search for meteorites on Mars. The scientists are using the NHM's extensive meteorite collection to test the spectral instruments destined for the ExoMars rover Rosalind Franklin, and develop tools to identify meteorites on the surface of the red planet. The project is being presented today (23 July) at the

Astronomers have for the first time imaged a moon-forming disk around an exoplanet. Scientists expect the discovery - made using the Atacama Large Millimetre/submillimeter Array and detailed Thursday in the journal Astrophysical Journal Letters - to aid the study of planet and moon formation in young solar systems. "Our work presents a clear detection of a disc in which satelli

The Avangard, the Kinzhal and now the Zircon - Russia is leading the race to develop a range of new hypersonic weapons that President Vladimir Putin has dubbed "invincible". Moscow's latest step came this week with another successful test of the Zircon, a ship-launched hypersonic missile. Fired from one of Russia's most powerful warships, the Admiral Gorshkov frigate, a Zircon travellin

The Paris Agreement adopted a target for global warming not to exceed 1.5°C. This sets a limit on the additional carbon we can add to the atmosphere – the carbon budget. Only around 17% of the carbon budget is now left. That is about 10 years at current emission rates.

Each country reports its annual greenhouse gas emissions to the United Nations. Scientists then set these emissions against estimates of the carbon absorbed by Earth’s natural carbon sinks. This is known as the bottom-up approach to calculating the carbon budget.

Another way to track carbon sources and sinks is
