Title: European Space Agency’s Aeolus Satellite Makes History with Assisted Re-Entry
In an unprecedented move, the European Space Agency (ESA) is undertaking a groundbreaking operation to bring back its highly successful observation satellite, Aeolus, after it exceeded its expected lifespan in orbit. This first-of-its-kind assisted re-entry endeavor aims to set a new standard for space safety and sustainability.
According to the ESA, there are currently 10,000 spacecraft in space, with a staggering 2,000 of them defunct. Recognizing the increasing risk of space debris, the agency is taking proactive measures to avoid potential harm to humans or infrastructure.
Launched in August 2018, Aeolus was originally designed for a research mission to test new technology. However, it has surpassed expectations by providing critical data to Europe’s meteorology centers, significantly improving global weather forecasts.
As the fuel in Aeolus nears depletion and its mission comes to a close, the ESA plans to bring the satellite back to Earth with an assisted re-entry. This operation involves maneuvering Aeolus into Earth’s atmosphere when it reaches an altitude of 280 kilometers, with controllers gradually reducing its altitude over four stages.
At its current rate of descent, the satellite is falling back to Earth at approximately 1 kilometer per day. It is estimated that around 80% of Aeolus will burn up upon re-entry, with the remaining 20% or less landing in a designated area of the Atlantic Ocean. This meticulous approach aims to minimize any potential risks associated with the satellite’s return to Earth.
ESA’s mission to clean up space debris is one of its core focuses, as access to space continues to increase and more constellations and satellites are launched. The agency has set a goal that every spacecraft developed after 2030 will be “debris neutral”, contributing to a safer and more sustainable space environment.
The assisted re-entry of Aeolus symbolizes a pioneering effort in space safety and sustainability. By successfully bringing back the satellite, ESA hopes to inspire and set an example for future space debris cleanup missions. As the countdown to Aeolus’ return begins, the eyes of the space community eagerly await the outcome of this historic operation.
