A non-proprietary Mission Concept available for presentation to NASA, providing High Area, High Resolution Imaging Spectroscopy and Timing with Arcmin Angular Resolution Submitted in response to NASA 2011 RFI NNH11ZDA018L Concepts for the Next NASA X-ray Astronomy Mission
The Solar Spectroscopy Explorer (SSE) concept is conceived as a scalable mission, with two to four instruments and a strong focus on coronal spectroscopy. In its core configuration it is a small strategic mission ($250-500M) built around a microcalor
imeter (an imaging X-ray spectrometer) and a high spatial resolution (0.2 arcsec) EUV imager. SSE puts a strong focus on the plasma spectroscopy, balanced with high resolution imaging - providing for break-through imaging science as well as providing the necessary context for the spectroscopy suite. Even in its smallest configuration SSE provides observatory class science, with significant science contributions ranging from basic plasma and radiative processes to the onset of space weather events. The basic configuration can carry an expanded instrument suite with the addition of a hard X-ray imaging spectrometer and/or a high spectral resolution EUV instrument - significantly expanding the science capabilities. In this configuration, it will fall at the small end of the medium class missions, and is described below as SSE+. This scalable mission in its largest configuration would have the full complement of these instruments and becomes the RAM (Reconnection And Microscale) mission. This mission has been designed to address key outstanding issues in coronal physics, and to be highly complementary to missions such as Solar Probe Plus, Solar Orbiter, and Solar-C as well as ground-based observatories.
