IRIS - The Interface Region Imaging Spectrograph - examines how solar material moves, gathers energy, and heats up as it travels through a little-understood region in the sun's lower atmosphere. Observing how material and energy move through this region will provide more insight into the dynamics of the Sun to help explain what causes the ejection of solar material, in the form of the steady solar wind or larger, explosive Coronal Mass Ejections - that influence near-Earth space weather.
The Van Allen Probes are a pair of spacecraft dedicated to the study of Earth's Radiation Belts, in particular radiation belt dynamics in the influence of the fluctuating solar wind which will not only provide valuable information on near-Earth Space, but also provide insights in fundamental processes ongoing at other planets.
NuSTAR, the Nuclear Spectroscopic Telescope Array, is the first mission to deploy a focusable telescope to map the sky in high energy radiation (X-Ray - 9-79kEV). The Spacecraft will take a census of collapsed stars and black holes in different areas and of different sizes. NuSTAR will make observations in our galaxy – the Milky Way – and deep observations of the extragalactic sky.
