Starlink satellites enable detailed mapping of Earth's upper atmosphere

Scientists have found a new use for SpaceX's Starlink constellation, using orbital data from around 1,200 satellites to study Earth's upper atmosphere. Researchers analyzed the data to estimate density levels in the thermosphere, a region that has historically been difficult to observe. The method produces two-dimensional maps showing variations in atmospheric density across the region. The findings highlight an unexpected scientific benefit of large commercial satellite networks. This approach could open new avenues for understanding atmospheric behavior at high altitudes.
