Related Facts:-
- On 10 February 2022 NASA stated that it has selected two science missions to study the Sun and the Sun- Earth connected environment.
- These missions are the Multi-slit Solar Explorer (MUSE) and HelioSwarm which help to improve our understanding the constantly changing space environment.
- These missions will provide deeper insights into our universe and offer critical information to help protect astronauts, satellites, and communications signals such as GPS.
- Multi-slit Solar Explorer (MUSE):
- The MUSE mission will help scientists understand the forces driving the heating of the Sun’s corona.
- It will record the eruptions in that outermost region of the Sun that are at the foundation of space weather.
- The mission will offer deeper insight into the physics of the solar atmosphere by using a powerful instrument known as a multi-slit spectrometer.
- It will observe the Sun’s extreme ultraviolet radiation and obtain the highest resolution images ever captured of the solar transition region and the corona.
- HelioSwarm:
- The HelioSwarm mission is a constellation or swarm of nine spacecraft that will study the solar wind.
- It will help to capture the first multiscale in-space measurements of fluctuations in the magnetic field and motions of the solar wind.
- The Sun’s outermost atmospheric layer, the heliosphere, encompasses an enormous region of the solar system.
- Solar winds spread through the heliosphere, and their interactions with planetary magnetospheres and disruptions such as coronal mass ejections affect their turbulence.
