New research, based largely on information from the Copernicus Sentinel-1 and ESA’s CryoSat satellite missions, has revealed alarming findings about the state of Antarctica's ice shelves: 40% of these floating shelves have significantly reduced in volume over the past quarter-century. While this underscores the accelerating impacts of climate change on the world's southernmost continent, the picture of ice deterioration is mixed. View the full article

When astronauts return to the lunar surface they are probably going to be doing more driving than walking – but to keep billowing moondust at bay they are going to need roads. An ESA project reported in today’s Nature Scientific Reports tested the creation of roadworthy surfaces by melting simulated moondust with a powerful laser. View the full article

Video: 00:03:42 Meet Hera, our very own asteroid detective. Together with two CubeSats – Milani the rock decoder and Juventas the radar visionary – Hera is off on an adventure to explore Didymos, a double asteroid system that is typical of the thousands that pose an impact risk to planet Earth. Do Hera and her CubeSats have the right stuff to explore space? Before launch they need to prove it, with a round of testing at the ESTEC Test Centre in the Netherlands – Europe’s largest satellite test facility. Suitable for kids and adults alike, this episode of ‘The Incredible Adventures of Hera’ explains all the tests that Hera has to go through, using facilities that …

Governments and international disaster response teams have long relied on satellites to assess the impacts of disasters such as earthquakes and hurricanes. Now ESA has partnered with ICEYE, a Finnish microsatellite manufacturer, to improve early warning systems for floods and wildfires and extend their geographical coverage globally.

Video: 00:03:44 Nestled between the colossal martian ‘Grand Canyon’ (Valles Marineris) and the tallest volcanoes in the Solar System (the Tharsis region) lies Noctis Labyrinthus – a vast system of deep and steep valleys that stretches out for around 1190 km (roughly the length of Italy here on Earth). This video visualises a flight over the eastern part of Noctis Labyrinthus as seen by Mars Express’s High Resolution Stereo Camera (HRSC). It presents a perspective view down and across this fascinating landscape, showing distinctive ‘graben’ – parts of the crust that have subsided in relation to their surroundings. The intense volcanism in the nearby Tharsis region …

With many people around the world suffering from various forms of malnutrition it’s important that the absolute basics such as rice, soya and wheat are as nourishing as possible. ESA-funded research shows that the Copernicus Sentinel-2 mission and the Italian Prisma mission could be used to monitor the nutritional content of staple crops. This could, for example, help farmers take appropriate steps to boost the quality of their crops as they grow. View the full article

The smallest flowering plant on Earth might become a nutritious foodstuff for astronauts in the future, as well as a highly efficient source of oxygen. To help test their suitability for space, floating clumps of watermeal – individually the size of pinheads – were subjected to 20 times normal Earth gravity aboard ESA’s Large Diameter Centrifuge by a team from Mahidol University in Thailand.

Our planet is being continuously bathed in radio signals from satnav satellites – which are useful for much more than just navigation. Dedicated space missions acquire these signal reflections to amass valuable environmental information. The shoebox-sized PRETTY CubeSat, flying on Europe’s next Vega launcher, will investigate a new frequency and novel observation angle to better measure the rate of climate change – at the same time as gathering radiation data on its surrounding space environment.

Thanks to their ability to absorb and store carbon dioxide from the atmosphere, forests have long been recognised as a key tool in the fight against climate change – but not all forests are equal. New research based on data from ESA’s SMOS satellite mission has found that, surprisingly, young trees are champions at carbon capture. View the full article

Measurements from the Copernicus Sentinel-5P satellite show that this year’s ozone hole over Antarctica is one of the biggest on record. The hole, which is what scientists call an ‘ozone depleting area,’ reached a size of 26 million sq km on 16 September 2023. This is roughly three times the size of Brazil. View the full article
