STEREO-A — spacecraft, explore its interactive 3D model in Cosmoscope.
Explore STEREO-A in a 3D Solar System. Follow its published mission trajectory and inspect its distance and spacecraft facts.
One of NASA’s twin solar observatories, STEREO-A circles the Sun slightly faster than Earth, drifting around to see solar storms side-on. It swung back past Earth in 2023; its twin, STEREO-B, fell silent in 2014.
Explore STEREO-A along its published mission trajectory in the 3D Solar System. The model uses the available ephemeris interval; historical missions are not active spacecraft and extrapolations beyond an ephemeris interval are approximate.
