The National Aeronautics and Space Administration (Nasa) approved a major contribution to the Japan Extreme Ultraviolet High Throughput Spectroscopy Telescope (EUVST) mission.
The mission, led by the Japan Aerospace Exploration Agency, involves a solar telescope that will study the way the sun’s atmosphere escapes into the solar wind. This is a constant current of sleet, which flows through the solar system and produces “space weather”
EUVST will study in detail the sun at ultraviolet wavelengths. It is also called Solar-C, and the goal is to launch in the mid-2020s. Japan’s previous solar mission Hinode or Solar-B was launched in 2006.
The National Aeronautics and Space Administration (Nasa) also announced funding for its Electrojet Zeeman Imaging Explorer (EZIE) mission. EZIE, led by the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, will study the currents in the Earth’s atmosphere to further understand how the solar wind interacts with the Earth’s magnetic field to produce aurora. EZIE consists of three small “cube satellites” and will be launched sometime after June 2024.
