Video: 00:05:00 ESA’s wind mission Aeolus is coming home. After five years of improving weather forecasts, the satellite will return in a first-of-its-kind assisted reentry. At ESA’s Space Operations Centre in Germany, mission control will use the satellite’s remaining fuel to steer Aeolus during its return to Earth. Find out more about the mission, its successes and how Aeolus is paving the way for safe reentries. View the full article

Astronomers using the NASA/ESA/ Hubble Space Telescope’s extraordinary sensitivity have discovered a swarm of boulders that were possibly shaken off the asteroid Dimorphos when NASA deliberately slammed the half-tonne DART impactor spacecraft into Dimorphos at approximately 22 500 kilometres per hour. DART intentionally impacted Dimorphos on 26 September 2022, slightly changing the trajectory of its orbit around the larger asteroid Didymos. View the full article

The Italian region of Emilia-Romagna was devastated by severe floods in May 2023, claiming lives and displacing thousands of people, resulting in an estimated €8.8 billion in damages. With the region still grappling with the aftermath, satellites have been instrumental in assessing the damages of the affected areas. View the full article

For the first time, the NASA/ESA/CSA James Webb Space Telescope has observed the chemical signature of carbon-rich dust grains at redshift ~ 7 [1], which is roughly equivalent to one billion years after the birth of the Universe [2]. Similar observational signatures have been observed in the much more recent Universe, attributed to complex, carbon-based molecules known as polycyclic aromatic hydrocarbons (PAHs). It is not thought likely, however, that PAHs would have developed within the first billion years of cosmic time. View the full article

Video: 00:45:00 After completing its mission in orbit, ESA’s wind mission Aeolus will soon reenter Earth's atmosphere. Currently orbiting 320 km above, Aeolus is being kept in orbit with its remaining fuel. This fuel is running out, and the satellite will soon succumb to Earth’s atmosphere and gravity. Going above and beyond what the satellite was technically designed to do, ESA is attempting a first-of-its-kind assisted reentry to reduce the (already very small) risk of damage from any fragments that survive the journey and reach the ground. ESA held an online media briefing on 19 July 2023 to explain more about this assisted approach and answer questions. Vi…

Fuelled largely by climate change, our planet is being subjected to environmental changes that are having an unprecedented global impact on humans, animals and plants. Shockingly, in certain locations these changes are occurring at a rate never before witnessed. To keep pace with the challenges we face, ESA is embarking on a new Earth observation science strategy – and has reached out to the scientific community at this early stage in the process to help guide the Agency’s scientific agenda for the coming years.

Isn’t it strange that when satellites run out of fuel or a single component breaks down, we just discard them? ESA and European industry have joined forces to make sure that our satellites can live on. View the full article
