Nasa has approved a large contribution to Japan’s Extreme Ultraviolet High-Throughput Spectroscopic Telescope (EUVST) mission.
Led by the Japan Aerospace Exploration Agency, the mission involves a solar telescope that will study the way the sun’s atmosphere detaches to become the solar wind. This is a constant sleet of particles that flows through the solar system creating “space weather” that sparks the polar lights on Earth, and disrupts technology. Along with other solar missions, such as the European Space Agency’s Solar Orbiter and Nasa’s Parker Solar Probe, EUVST will help provide a comprehensive investigation into space weather.
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.
