Parker Solar Probe Teams Up With Observatories Around Solar System for 4th Solar Encounter
Posted on 06/16/2020 10:34:10At 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.
