Cluster reentry ground track

On 8 September 2024, the first of four satellites that make up ESA’s Cluster mission will reenter Earth’s atmosphere over the South Pacific Ocean Uninhabited Area.

This marks the end of the historic mission, over 24 years after it was sent into space to measure Earth’s magnetic environment. Though the remaining three satellites will also stop making scientific observations, discoveries using existing mission data are expected for years to come.

This ‘targeted reentry’ is the first of its kind. ESA’s efforts to ensure a clean end to the Cluster mission go beyond international standards, making the agency a world-leader in sustainable space exploration.
