This visualization shows many of the spacecraft in NASA's heliophysics great observatory fleet. The heliophysics fleet explores various aspects of the helipsphere including Earth's magnetosphere. To do this requires many spacecraft sampling data at many different places — close to the Earth, between the Earth and the Sun, and far away from the Earth.
Phase-1 of this visualziation shows the orbits of spacecraft around the date when the Stereo spacecraft received lunar assists to get into solar orbit. This phase focuses on near-Earth orbiters and L1 orbiters.
