The US National Aeronautics and Space Administration (NASA) announced the decision to take part in two heliophysical missions aimed at studying the nature of solar winds and space weather in general.
We are talking about programs Extreme Ultraviolet High-Throughput Spectroscopic Telescope Epsilon Mission (EUVST) or Solar-C EUVST Mission and Electrojet Zeeman Imaging Explorer (EZIE), which are among three projects related to the study of space weather, which were selected by the space agency in September 2019 for mission concept research.
The EUVST mission, which will launch a solar telescope into space in 2026, will study how the solar atmosphere emits solar wind and causes eruptions of solar material that affects the level of cosmic radiation. The project is led by the Japan Aerospace Exploration Agency (JAXA), and NASA will provide $ 55 million for its implementation and will provide some equipment and software, including a UV detector and auxiliary electronics, spectrograph components, a pointing telescope, software and an imaging system.
The second EZIE mission will use three small CubeSat satellites, slated for launch in 2024, to study the source and changes in the auroral electrojet, an electrical current that circulates in the Earth’s atmosphere about 60-90 miles (97-145 km) above the surface and propagates into the Earth’s magnetosphere. The same phenomena that cause the aurora can also interfere with the transmission of radio and communications signals, and cause damage to spacecraft in orbit. The total budget for the EZIE mission is $ 53.3 million.
Missions like these allow scientists to gather the information they need to understand the physics of various solar phenomena.
