Defunct European Satellite Set for Uncontrolled Reentry Mid-February

The ERS-2 satellite, decommissioned in 2011, will reenter Earth's atmosphere in an uncontrolled descent, posing minimal risk to individuals.

  • A defunct European satellite, ERS-2, launched in 1995, is set to reenter Earth's atmosphere in an uncontrolled descent around mid-February.
  • ERS-2 completed its mission in 2011 and has been in a slow orbital decay due to solar activity, leading to its imminent reentry.
  • Despite the uncontrolled nature of its descent, the risk of injury from space debris to an individual is extremely low, under 1 in 100 billion.
  • ERS-2 collected significant data on Earth's climate, including polar ice, sea-level rise, and atmospheric chemistry, contributing to our understanding of climate change.
  • Space agencies are working on technologies for controlled reentries to minimize space debris and ensure orbit safety.
