NASA’s Parker Solar Probe Flies Through Coronal Mass Ejection Written 18 September 2023

Forbes reports that NASA’s Parker Solar Probe “has become the first spacecraft ever to fly through a coronal mass ejection from the sun—a powerful eruption of billions of tons of plasma.” The closest spacecraft to the sun, “launched in Aug. 2018, spent two days within a CME while just 5.7 million miles (9.2 million kilometers) from the solar surface.” For context, Mercury “is 23 million miles (37 million kilometers) from the sun and Earth is a whopping 93 million miles (150 million kilometers) distant.” As revealed in a paper published in The Astrophysical Journal, Parker “passed right through the CME on Sept. 22, 2022, crossing the wake of its leading edge—its shock wave.” The moments were “captured by the probe’s Wide-field Imager for Solar Probe (WISPR) instrument and are published on YouTube.” Parker Solar Probe Project Scientist at the Johns Hopkins Applied Physics Laboratory Nour Raouafu said, “This is the closest to the sun we’ve ever observed a CME. We’ve never seen an event of this magnitude at this distance.”
