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.
