EZIE & EUVST: Two Heliophysics Missions

• The US space agency National Aeronautics and Space Administration (NASA) has approved two heliophysics missions. Heliophysics is the science of understanding the Sun and its interactions with Earth and the solar system, including space weather.
• Of the two missions, NASA will lead the Electrojet Zeeman Imaging Explorer or EZIE mission, while it would contribute to the Japan Aerospace Exploration Agency (JAXA)-led Extreme Ultraviolet High-Throughput Spectroscopic Telescope Epsilon Mission (EUVST) mission.
• The EZIE mission will study the atmosphere of the Earth and the electric currents in it, which link the aurora to the magnetosphere. ....
