The European Space Agency (ESA) is closely monitoring the reentry of its Earth-observing satellite, ERS-2, which is expected to largely burn up in Earth\u2019s atmosphere on Wednesday morning. The agency\u2019s Space Debris Office, in collaboration with an international surveillance network, is tracking the satellite, predicting its reentry at 6:14 a.m. ET Wednesday, within a 15-hour window of uncertainty. Live updates on the satellite\u2019s status are available on the ESA\u2019s website.<\/p>\n
\u201cAs the spacecraft\u2019s reentry is \u2018natural\u2019, without the possibility to perform maneuvers, it is impossible to know exactly where and when it will reenter the atmosphere and begin to burn up,\u201d stated the agency.<\/p>\n
The exact timing of the satellite\u2019s reentry remains unclear due to the unpredictability of solar activity, which can affect the density of Earth\u2019s atmosphere and the satellite\u2019s trajectory. Solar activity has been increasing as the sun approaches its 11-year cycle\u2019s peak, known as solar maximum, expected later this year. This heightened activity has already accelerated the reentry of ESA\u2019s Aeolus satellite in July 2023.<\/p>\n
With an estimated mass of 5,057 pounds (2,294 kilograms) after depleting its fuel, ERS-2 is comparable in size to other space debris that reenters Earth\u2019s atmosphere regularly, approximately every week. The satellite is anticipated to break apart at around 50 miles (80 kilometers) above Earth\u2019s surface, with most fragments burning up in the atmosphere. The agency assures that any remaining fragments are unlikely to contain harmful substances and will likely fall into the ocean.<\/p>\n
ERS-2, launched on April 21, 1995, was the most advanced satellite of its kind developed and launched by Europe at the time. Alongside its twin, ERS-1, it gathered crucial data on Earth\u2019s polar caps, oceans, and land surfaces, observing natural disasters like floods and earthquakes in remote areas. The data collected by ERS-2 remains valuable and is still utilized today.<\/p>\n
In 2011, the ESA made the decision to end the satellite\u2019s operations and initiate its deorbiting process to prevent it from becoming space debris. The satellite executed 66 deorbiting maneuvers in July and August of 2011, depleting its fuel and gradually decreasing its altitude. This set ERS-2 on a trajectory to spiral closer to Earth over 15 years and eventually reenter the atmosphere.<\/p>\n
According to the agency, the probability of an individual being injured by space debris annually is less than 1 in 100 billion, significantly lower than the risk of being involved in a home accident.<\/p><\/p>\n","protected":false},"excerpt":{"rendered":"
