IMAP

Interstellar Mapping and Acceleration Probe (IMAP) will help researchers better understand the boundary of the heliosphere, a magnetic barrier surrounding our solar system. This region is where the constant flow of particles from our Sun, called the solar wind, collides with winds from other stars. This collision limits the amount of harmful cosmic radiation entering the heliosphere. IMAP will collect and map neutral particles that make it through, as well as investigate the fundamental processes of how particles are accelerated in space, from its vantage point orbiting the Sun at the Lagrange 1 point directly between the Sun and Earth.

Space Weather Follow On-Lagrange 1 (SWFO-L1) is a spacecraft mission planned to monitor signs of solar storms, which may pose harm to Earth's telecommunication network. The spacecraft will be operated by the National Oceanic and Atmospheric Administration (NOAA). It is planned to be placed at the Sun–Earth L1 Lagrange point, a location between the Earth and the Sun. This will allow SWFO-L1 to continuously watch the solar wind and energetic particles heading for Earth.

GLIDE (Global Lyman-alpha Imagers of the Dynamic Exosphere) is a mission by NASA led by Electrical and Computer Engineering at the University of Illinois to make unprecedented measurements of the far ultraviolet light emitted by hydrogen atoms in the Earth’s outermost atmospheric layer, known as the exosphere, which extends almost halfway to the moon. This bright emission serves as a tracer of exospheric density and spatial structure, knowledge of which is needed to advance understanding of upper atmospheric physics, particularly regarding Earth’s recovery from solar-driven disturbances known as space weather.
