NASA has a fleet of spacecraft strategically placed throughout our heliosphere—from Parker Solar Probe at the Sun observing the very start of the solar wind, to satellites around Earth, to the farthest human-made object, Voyager, which is sending back observations on interstellar space. Each mission is positioned at a critical, well-thought out vantage point to observe and understand the flow of energy and particles throughout the solar system—all helping us untangle the effects of the star we live with.

The graphics below show the Heliophysics Division fleet as of December 2025. Green indicates missions in operation and blue indicates missions in extended operation. Numbers in parentheses indicate how many spacecraft the mission currently includes.
