Video: 00:02:10 Detect, fetch and collect. A seemingly easy task is being tested to find the best strategy to collect samples on the martian surface, some 290 000 km away from home. Testing technologies for Mars exploration is part of the daily job of Laura Bielenberg, an ESA young graduate trainee for the Mars Sample Return campaign. The test takes place at the rock-strewn recreation of the Red Planet at ESA’s ESTEC technical centre in Noordwijk, the Netherlands. The nickname of this test site is the ‘Mars Yard’ and is part of the Planetary Robotics Laboratory. The tube is a replica of the sample caches that NASA’s Perseverance rover is leaving on Mars hermetical…

Video: 00:12:42 Enjoy a sneak peek of ESA’s new documentary that looks at fire in all its fury - and how satellite technology is helping to mitigate this consequence of climate change. Join us on this journey as we meet the firefighter who fought one of the largest wildfires in his career, climate scientists working with satellite data, and the people on the frontline using these data to aid those affected. The full documentary will be released this summer. View the full article

The Arctic, once again at the forefront of climate change, is experiencing disproportionately higher temperature increases compared to the rest of the planet, triggering a series of cascading effects known as Arctic amplification. As concerns continue to grow, satellites developed by ESA have become indispensable tools in understanding and addressing the complex dynamics at play and the far-reaching consequences for the environment and human societies.

Lying in bed for a full 60 days – with one shoulder always touching the mattress – might sound like bliss, but add cycling, spinning and constant medical tests to the equation and it becomes a challenging experience for the sake of human space exploration. View the full article

Video: 00:01:20 Satellites play a vital role in monitoring the rapid changes taking place in the Arctic. Tracking ice lost from the world’s glaciers, ice sheets and frozen land shows that Earth is losing ice at an accelerating rate. Using information from ESA’s ERS, Envisat and CryoSat satellites as well as the Copernicus Sentinel-1 and Sentinel-2 missions, research led by Tom Slater of the University of Leeds, found that the rate at which Earth has lost ice has increased markedly within the past three decades. Currently, more than a trillion tonnes of ice is lost each year. To put this into perspective, this is equivalent to an ice cube measuring 10x10x10 km over…

Video: 00:03:54 The name of Andreas’s second mission to the Space Station is ‘Huginn’. Inspired by Norse mythology, the name is taken from one of two ravens who serve the god Odin. Called Huginn and Muninn, these two birds sit on Odin’s shoulders and are sent flying across the world at dawn. They return at night to inform him of the many events they have seen and heard. In Old Norse, ‘Huginn’ means ‘thought’ and ‘Muninn’ means ‘mind’ or ‘memory’. ESA astronaut Andreas Mogensen is going on his first long-duration mission to the International Space Station. Andreas will be the pilot on the SpaceX Crew Dragon that will carry him and the rest of Crew-7 to the Space S…

Adding to the grim list of record ice losses, record air temperatures and record droughts, which have all hit the headlines recently, the temperature of the surface waters of our oceans is also at an all-time high. With an El Niño looming, concerns are that we will soon be facing even worse extremes. Satellites orbiting overhead are being used to carefully track the patterns that lead up to El Niño to further understand and predict the consequences of this cyclic phenomenon against the backdrop of climate change.

The NASA/ESA/CSA James Webb Space Telescope has enabled another long-sought scientific breakthrough, this time for Solar System scientists studying the origins of the water that has made life on Earth possible. Using Webb’s NIRSpec (Near-Infrared Spectrograph) instrument, astronomers have confirmed gas – specifically water vapour – around a comet in the main asteroid belt for the first time, proving that water from the primordial Solar System can be preserved as ice in that region. However, the successful detection of water comes with a new puzzle: unlike other comets, Comet 238P/Read had no detectable carbon dioxide. View the full article
