NASA Plans Two Heliophysics Missions to Study the Sun, Earth’s Aurora and Space Weather

It’s official, NASA is set to launch two heliophysics missions – Extreme Ultraviolet High-Throughput Spectroscopic Telescope Epsilon Mission (EUVST) and Electrojet Zeeman Imaging Explorer (EZIE) – to explore the Sun and the accompanying system that propels space weather near Earth. This will help researchers better understand the physics that drive the solar wind and solar explosions, like solar flares as well as coronal mass ejections, and could one day help scientists predict these events, which can impact human technology, along with future space explorers.

NASA adds several hardware contributions to the mission, including an intensified UV detector, support electronics, spectrograph components, a guide telescope, software, and a slit-jaw imaging system to provide context for the spectrographic measurement. Currently, their budget is $55 million, and the principal investigator for the NASA contribution to the EUVST is Harry Warren at the U.S. Naval Research Laboratory in Washington.
