in general Decommissioned satellites tend to burn up when they return to Earth. But a few days ago, the European Space Agency (ESA) reported that Aeolus weighed 1,360 kilograms. Used to map the winds of the Earth from space and orbit the Earth for 5 years has successfully returned to Earth. The latter has been carefully designed to mitigate the damage in many ways from satellite debris. It is the first time that ESA mission control has attempted to re-enter the Earth’s atmosphere.
ESA scientists say they have decided to use the little remaining Aeolus fuel. in helping it not burn in the atmosphere and fell safely into the ocean in Antarctica. Starting on July 24, the satellite fell from the Sun Synchronous Orbit (SSO) at an altitude of 320 kilometers above the Earth. At an altitude of 280 km, the satellite’s engines burned out twice, lasting about 38 minutes in total. This reduced the satellite’s altitude to 250 km above the Earth. On 27 July, the satellite burned out four more engines. times lowered orbit to an altitude of 150 km, and on July 28, the satellite received its final command from ground control. As a result, it enters the atmosphere about five hours later and begins burning harmlessly.
Aeolus Satellite Named after the guardian of the winds in Greek mythology. It was launched into Earth orbit on August 22, 2018 by a Vega rocket from the Kuroo Space Center. in French Guiana to measure Earth’s wind patterns and improve short-term weather forecasts. To help expand our understanding of man-made climate change.
