Copernicus Sentinel-6B was launched on 17 November 2025, ready to continue a decades-long mission to track the height of the planet’s seas – a key measure of climate change. The satellite was carried into orbit on a Falcon 9 rocket from the Vandenberg Space Force Base in California, US.

Sentinel-6B follows in the footsteps of its predecessor, Sentinel-6 Michael Freilich, which was launched in 2020. The mission is the reference radar altimetry mission that continues the vital record of sea-surface height measurements until at least 2030.

Copernicus Sentinel-6 has become the gold standard reference mission to monitor and record

The latest guardian of our oceans has taken its place in orbit. The Copernicus Sentinel-6B satellite is now circling Earth, ready to continue a decades-long mission to track the height of the planet’s seas – a key measure of climate change.

The United States faces a narrowing window to claim its position as the first nation to return humans to the Moon in the 21st century. While NASA's official timeline targets Artemis 3 for no earlier than mid-2027 - roughly three years before China's 2030 lunar landing goal - the path forward is fraught with technical complexity, schedule pressure, and the kind of engineering challenges that have historically humbled even the most ambitious space programs.

University of Colorado Boulder researchers are expanding their work into space law following decades of experience in space exploration. The need for policy expertise has grown as countries continue to launch satellites, probes, and military hardware into orbit. Marcus Holzinger, professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences, is the inaugural Hatfie

The head of OHB says he is concerned about a planned joint venture among three of his competitors, even as the company sees opportunities from growing European space spending.

Since comet 3I/ATLAS, the third known interstellar object, was discovered on 1 July 2025, astronomers worldwide have worked to predict its trajectory. ESA has now improved the comet's predicted location by a factor of 10, thanks to the innovative use of observation data from our ExoMars Trace Gas Orbiter (TGO) spacecraft orbiting Mars. By being able to use Mars-based data for an unusual ob

Chandrayaan-3 was developed to demonstrate the capability for a controlled lunar landing, enable rover mobility on the Moon, and facilitate in-situ research. The mission includes a lander module, propulsion module, and rover. The satellite launched aboard LVM3 from SDSC SHAR, Sriharikota, on July 14, 2023. Following its lunar touchdown on August 23, 2023, the propulsion module maintained l
