A versitile rocket paylod

Micro-X is a NASA-funded sounding rocket program that has been under development for the past six years. The payload is an X-ray imaging spectrometer, consisting of an X-ray grazing-incicence optic, and optical bench, a cryogenic detector, and associated electronics. The 128 pixel TES-based microcalorimeter array has 3 eV FWHM energy resolution at 1 keV. This high-energy resolution allows Micro-X to take unprecedented spectra of various astronomical objects. The upcoming flight of Micro-X will observe the Puppis A supernova remnant and study the plasma emission from a shock in a region strongly interacting with the surrounding cool molecular gas. More details on the current incarnation of Micro-X can be found at the Micro-X website.

After that flight we will reconfigure Micro-X to perform wide (40° diameter) FOV observations without a mirror, which will allow Micro-X to observe a significant fraction of the dark matter in the Milky Way. Micro-X could see X-ray emission from dark matter if it is composed of particles that decay or de-excite emitting X-ray photons, such as sterile neutrinos.
