NASA Parker Solar Probe project scientist Nicola Fox of Johns Hopkins APL explains the Sun’s corona, visible during the August 21, 2017 total eclipse that will pass over much of the United States, and how Parker Solar Probe will help us unlock some of the mysteries of our star.

Launch preparations are beginning to get off the ground for NASA’s upcoming Parker Solar Probe mission, scheduled to lift off in summer 2018 atop a United Launch Alliance Delta IV Heavy rocket.
Two of the three common booster cores comprising the rocket’s first stage have arrived on the company’s Mariner ship, which delivered the components to Port Canaveral in Florida. From there the cores were offloaded and transported to the Horizontal Processing Facility at Cape Canaveral Air Force Station’s Space Launch Complex 37.
The Parker Solar Probe will perform the closest-ever observations of a star when it travels through the Sun’s atmosphere, called the corona. The probe will rely on measurements and imaging to revolutionize our understanding of the corona and the Sun-Earth connection.
Data coming back from orbit seemed to not make sense. The glow at the equator changed from place to place around the Earth in ways we didn’t expect.
Researchers from the U.S. Naval Research Laboratory, UC-Berkeley, and St. Cloud State University talk about the importance of MIGHTI, a space weather instrument set to launch on the ICON mission next summer.
The space surrounding our planet is full of restless charged particles and roiling electric and magnetic fields, which create waves around Earth. One type of wave, plasmaspheric hiss, is particularly important for removing charged particles from the Van Allen radiation belts, a seething coil of particles encircling Earth, which can interfere with satellites and telecommunications. A new study published in Journal of Geophysical Research using data from NASA’s Van Allen Probes spacecraft has discovered that hiss is more complex than previously understood.
The new study looked at a newly identified population of hiss waves at a lower frequency than usually studied. These low-frequency hiss waves are particularly good at cleaning out high-energy particles — those that can cause damage to satellites — from the radiation belts. The authors of the study noticed that low-frequency waves are actually a separate and unique population, tending to cluster in different regions around Earth compared to their high-frequency counterparts.
