Parker Solar Probe Teams Up with Observatories Around the Solar System for Fourth Solar Encounter

At the heart of understanding our space environment is the knowledge that conditions throughout space — from the Sun to the atmospheres of planets to the radiation environment in deep space — are connected.

Studying this connection – a field of science called heliophysics — is a complex task: Researchers track sudden eruptions of material, radiation, and particles against the background of the ubiquitous outflow of solar material.

A confluence of events in early 2020 created a nearly ideal space-based laboratory, combining the alignment of some of humanity’s best observatories — including Parker Solar Probe, during its fourth solar flyby — with a quiet period in the Sun’s activity, when it’s easiest to study those background conditions. These conditions provided a unique opportunity for scientists to study how the Sun influences conditions at points throughout space, with multiple angles of observation and at different distances from the Sun.
