NASA selects Johns Hopkins APL space weather mission for 2024 launch The Electrojet Zeeman Imaging Explorer will study the auroral electrojet, electrical currents flowing 60-90 miles above the north and south poles By Geoff Brown / Published Jan 8, 2021 A Johns Hopkins Applied Physics Laboratory-led mission to explore electric currents in Earth s atmosphere that link the aurora to our planet s magnetosphere has been selected by NASA to move forward to a scheduled launch in 2024. The Electrojet Zeeman Imaging Explorer, EZIE, is a set of three small spacecraft that will study the auroral electrojet, which are electrical currents flowing about 60 to 90 miles above the poles that link the beautiful aurora to the Earth s magnetosphere, and which responds to solar activity and other drivers. ....

NASA has approved two heliophysics missions to explore the Sun and the system that drives space weather near Earth. Together, NASA’s contribution to the Extreme Ultraviolet High-Throughput Spectroscopic Telescope Epsilon Mission, or EUVST, and the Electrojet Zeeman Imaging Explorer, or EZIE, will help us understand the Sun and Earth as an interconnected system. Understanding the physics that drive the solar wind and solar explosions – including solar flares and coronal mass ejections – could one day help scientists predict these events, which can impact human technology and explorers in space. ....

NASA is embarking on two heliophysics missions set to explore and understand the systems that control space weather near Earth. The two missions are called the Extreme Ultraviolet High-Throughput Spectroscopic Telescope Epsilon Mission (EUVST) and the Electrojet Zeeman Imaging Explorer (EZIE). Exploring the physics that drive solar winds and explosions could help future space explorers and serve to protect spacecraft and other space technologies. “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,” said Thomas Zurbuchen, associate administrator for science at NASA Headquarters in Washington. ....
