MUSE (MIDEX 10) [NASA]

MUSE (Multi-Slit Solar Explorer) is a mission in NASA's Explorer program which will help scientists understand the forces driving the heating of the Sun’s corona and the eruptions in that outermost region 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 to observe the Sun’s extreme ultraviolet radiation and obtain the highest resolution images ever captured of the solar transition region and the corona.

The mission will also provide complementary observations from heliophysics research such as the Extreme UltraViolet Spectroscopic Telescope and ground-based observatories.

The primary goal of the MUSE mission is to investigate the causes of coronal heating and instability, such as flares and coronal mass ejections, and gain insight into the basic plasma properties of the corona. MUSE will obtain high-resolution images of the evolution of solar flare ribbons in a field of view focused on a large, active region on the Sun.
