NASA Gives Green Signal To Two Heliophysics Missions To Explore The Sun

The US Space Agency NASA has approved two heliophysics missions to study the Sun and the system, which makes space atmosphere near Earth. Scientists have said that both missions, Extreme Ultraviolet High-Throughput Spectroscopic Telescope Epsilon Mission (EUVST) and the Electrojet Zeeman Imaging Explorer (EZIE) will allow them to assess the Sun and Earth as a unified system. Studying physics, which is liable for the solar wind and solar explosions such as solar flares and coronal mass ejections will allow scientists to predict these events, which might affect human technology and explorers in space. The EUVST Epsilon mission is being led by the Japan Aerospace Exploration Agency (JAXA). Some other international partners as well are involved in the mission. It is expected to be launched by 2026. EUVST is a solar telescope, which will study how the solar atmosphere emits solar winds and triggers explosions of solar matter. These events affect the space radiation atmosphere across the solar system. NASA has provided hardware assistance to the mission, such as an intensified UV detector and support electronics, spectrograph parts, a guide telescope, software, and a slit jaw imaging system to offer context for spectrographic measures. The Space Agency has granted around $55 million to the EUVST mission. Harry Warren at the US Naval Research Laboratory in Washington will lead the mission from NASA.

The EZIE will look at the electric currents in the atmosphere of earth, which links Aurora to the magnetosphere of Earth. Earth’s magnetosphere is one part of the complex space weather system of Earth, which reacts to solar activity and other factors. The Auroral Electrojet (AE) index is a usual rate of geomagnetic activity levels, even if the details of the pattern of these currents are not known. Scientists have said that the EZIE is not going to be launched before 2024. The total cost of this mission is nearly $53.3 million. Jeng-Hwa aka Sam from the John Hopkins University Applied Physics laboratory is going to head the mission. The officials from NASA have said that they are soon going to add these new missions into the rising fleet of satellites, which will study the Sun-Earth system with the help of a wide range of observational tools.

The EUVST mission is going to track the references made by a 2017 final report done by the multi-agency Next Generation Solar Physics Mission Science Objectives Team. This mission will take inclusive UV spectroscopy calculations of the solar atmosphere with the finest level of details. It will allow scientists to see how differently coronal heating and energy discharge are driven by magnetic and plasma methods. Scientists have said that the new mission will give new insight into the sun. The EZIE mission will have a trio of CubeSats, which will look into the source and changes in an electric current, which circles the atmosphere of Earth. They have said that the use of instrument technology of EZIE has been proven on Earth Science CubeSat task. It shows that science and technology progress go hand in hand at NASA. Such missions are funded by The Heliophysics Explorers Program at NASA’s Goddard Space Flight Center.
