The European Space Agency’s defunct satellite, ERS-2, is set to make its return to Earth this week after 16 years in space, predicted to re-enter the atmosphere on Wednesday around 10 a.m. ET. Launched in 1995, the satellite was initially intended for a three-year mission but surpassed expectations, remaining operational until 2011, supporting over 5,000 projects and providing critical data on polar ice, sea levels, and atmospheric conditions.
After completing its final mission, the ESA conducted 66 de-orbiting maneuvers to ensure the satellite’s safe return to Earth and prevent it from remaining in space for over 100 years. The majority of the 2.5-ton satellite is expected to disintegrate upon re-entry, with any remaining debris likely to land in a body of water, although the agency does not have a precise prediction for the landing site.
Throughout its years in space, ERS-2 played a crucial role in advancing Earth observation capabilities, contributing to a wide range of scientific research and data collection. Its natural re-entry marks the end of a significant chapter in the history of space exploration and highlights the importance of responsible satellite disposal and management to ensure the safety and sustainability of activities in outer space.
As the global community continues to expand its presence in space, the safe and controlled de-orbiting of satellites and space debris will become increasingly important to mitigate the risks of collisions and maintain the sustainability of space exploration. The conclusion of ERS-2’s mission serves as a reminder of the long-term impact and implications of space activities on Earth and the need for careful planning and management of space assets.
