Washington: NASA has authorized two missions to discover the Sun and the technique that drives space climate close to Earth. These two missions are Extreme Ultraviolet High-Throughput Spectroscopic Telescope Epsilon Mission, or EUVST, and the Electrojet Zeeman Imaging Explorer, or EZIE.
Together, NASA’s contribution to the missions will assistance us fully grasp the Sun and Earth as an interconnected technique, the US space agency mentioned on Tuesday.
Understanding the physics that drive the solar wind and solar explosions — which includes solar flares and coronal mass ejections — could one particular day assistance scientists predict these events, which can influence human technologies and explorers in space.
“We are very pleased to add these new missions to the growing fleet of satellites that are studying our Sun-Earth system using an amazing array of unprecedented observational tools,” Thomas Zurbuchen, Associate Administrator for Science at NASA headquarters in Washington, mentioned in a statement.
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.
These phenomena propagate out from the Sun and influence the space radiation atmosphere all through the solar technique. NASA’s hardware contributions to the mission consist of an intensified UV detector and assistance electronics, spectrograph elements, a guide telescope, application, and a slit-jaw imaging technique to provide context for the spectrographic measurement.
The price range for NASA contributions to EUVST is $55 million. The Electrojet Zeeman Imaging Explorer (EZIE) will study electric currents in Earth’s atmosphere linking aurora to the Earth’s magnetosphere — one particular piece of Earth’s difficult space climate technique, which responds to solar activity and other elements.
The Auroral Electrojet (AE) index is a popular measure of geomagnetic activity levels, even even though the specifics of the structure of these currents is not understood. EZIE will launch no earlier than June 2024, NASA mentioned, adding that the total price range for the mission is $53.3 million.
