The European Space Agency (ESA) is preparing for the controlled reentry of its Aeolus wind mission satellite, which significantly enhanced global weather forecasts since its launch in 2018. As the mission has exceeded its expected lifespan and is running low on fuel, ESA plans to lower Aeolus into Earth’s atmosphere, ensuring it burns up safely. With a mass of 1360 kg, Aeolus has been instrumental in atmospheric research by mapping global winds and aiding climate studies. The satellite is currently orbiting at 320 km and will ultimately descend to 150 km before disintegrating at approximately 80 km. The reentry trajectory is designed to target open ocean areas, minimizing the risk of debris reaching populated land regions. The mission has outlasted its intended three years by more than 18 months and concluded operations on April 30, 2023. The upcoming reentry will set a precedent for responsible management of space debris, crucial for sustainable future missions. ESA aims to shield Earth from potential hazards while emphasizing safety in end-of-life spacecraft operations. The targeted reentry is expected to occur by the end of August, subject to solar activity influencing the satellite’s descent.
