Space has led to technological innovations with wide-ranging applications in healthcare. Beyond consumer gadgets, such as wireless headsets and scratch-resistant lenses, space exploration is a catalyst for understanding the human body and advancing scientific results that benefit people worldwide. Here are Europe’s top 5 stories in space for your health. Gravity affects everything we do and everything that happens inside and around us. On Earth’s surface, everything is subject to an average gravitational acceleration of 9.81 m/s2, or what we call 1 g. This acceleration keeps us grounded but it also influences all reactions and phenomena around us, from falling apples to c…

Video: 00:09:47 According to the Food and Agriculture Organization (FAO), global agricultural production will need to increase by 60% by 2050 to meet the food demands of the growing global population. A new satellite called Copernicus Hyperspectral Imaging Mission for the Environment, or CHIME, is being developed to support EU policies on the management of natural resources – ultimately helping to address the global issue of food security. CHIME will carry a unique visible to shortwave infrared spectrometer to provide routine hyperspectral observations to support new and enhanced services for sustainable agricultural and biodiversity management, as well as soil pr…

Using the unprecedented capabilities of the NASA/ESA/CSA James Webb Space Telescope, an international team of scientists has obtained the first spectroscopic observations of the faintest galaxies during the first billion years of the Universe. These findings help answer a longstanding question for astronomers: what sources caused the reionisation of the Universe? View the full article

Video: 00:02:10 The largest components for the first flight model of Europe’s new rocket Ariane 6 arrived at the port of Pariacabo in Kourou, French Guiana on 21 February 2024 via the novel ship, Canopée (canopy in French). The Ariane 6 stages and components are all manufactured across Europe. On this trip, Canopée brought the central core for Ariane 6’s first flight. The main engine and the main stage were integrated in Les Mureaux, France, while the upper stage and insulation for the rocket’s exterior were built up in Bremen, Germany. The various Ariane 6 components are then offloaded and transported by road to the new Ariane 6 launch vehicle assembly building j…

ESA’s Hera spacecraft for planetary defence is being prepared for a journey to the distant asteroid moon Dimorphos orbiting around its parent body Didymos. One of the first features Hera will look for is the crater left on Dimorphos by its predecessor mission DART, which impacted the asteroid to deflect its orbit. Yet a new impact simulation study reported in Nature Astronomy today suggests no crater will be found. The DART impact is likely to have remodelled the entire body instead – a significant finding for both asteroid science and planetary defence. View the full article

Video: 00:03:29 Mission complete. ESA’s second European Remote Sensing (ERS-2) satellite has reentered Earth’s atmosphere over the North Pacific Ocean. The satellite returned at 18:17 CET (17:17 UTC) between Alaska and Hawaii. ERS-2 was launched almost 30 years ago, on 21 April 1995. Together with ERS-1, it provided invaluable long-term data on Earth’s land surfaces, ocean temperatures, ozone layer and polar ice extent that revolutionised our understanding of the Earth system. ERS-2’s reentry was ‘natural’. ESA used the last of its fuel, emptied its batteries and lowered the satellite from its altitude of 785 km to 573 km. This reduced the risk of collision with o…

The NASA/ESA/CSA James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, occurred 160 000 light-years from Earth in the Large Magellanic Cloud. SN 1987A was observed on Earth in 1987, the first supernova that was visible to the naked eye since 1604 — before the advent of telescopes. View the full article

Video: 00:15:00 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 operations in the polar…

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.

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.
