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.
- According to the NASA, 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.
- EUVST Mission: The Japan Aerospace Exploration Agency (JAXA) leads the Extreme Ultraviolet High-Throughput Spectroscopic Telescope (EUVST) Epsilon Mission (Solar-C EUVST Mission), along with other international partners. Targeted for launch in 2026, EUVST is a solar telescope that will study how the solar atmosphere releases solar wind and drives eruptions of solar material.
- EZIE: The Electrojet Zeeman Imaging Explorer (EZIE) will study electric currents in Earth’s atmosphere linking aurora to the Earth’s magnetosphere – one piece of Earth’s complicated space weather system, which responds to solar activity and other factors.
- The Auroral Electrojet (AE) index is a common measure of geomagnetic activity levels, even though the details of the structure of these currents is not understood. EZIE will launch no earlier than June 2024.
