NASA Heliophysics Mission Sun Earth Aurora 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.

We are very pleased to add these new missions to the growing fleet of satellites that are studying our Sun-Earth system using an amazing array of unprecedented observational tools. In addition to my enthusiasm at selecting a pioneering multi-point observatory focused on the auroral electrojets, I am particularly excited to follow up the success of the Yohkoh and Hinode solar science missions with another international collaboration with JAXA and other European partners on EUVST,” said Thomas Zurbuchen, associate administrator for science at NASA Headquarters in Washington.
