XARM ( X-ray Astronomy Recovery Mission) ma częściowo zastąpić utraconą misję Hitomi. Będzie o połowę mniej teleskopów (2). Wkład NASA będzie powtórzony.
XARM will instead carry replacements for Hitomi’s two lower-energy instruments — the Soft X-ray Imager and the Soft X-ray Spectrometer. Both instruments contain critical parts provided by NASA, and the spectrometer is primarily a U.S.-developed payload.
“The mission will not be a carbon copy (of Hitomi), but the NASA contribution will be a carbon copy,” Hertz said in an interview. “The XARM mission is going to have only two of the four instruments that Hitomi had. It will have the Soft X-ray Spectrometer and the Soft X-ray Imager. The latter is a JAXA instrument, but we provided the telescope for both of those.”
XARM will not need an extendable 20-foot (6-meter) boom like Hitomi, Hertz said, because it will fly without the hard X-ray instruments that needed the deployable arm. Hard X-rays are at the higher-energy, shorter-wavelength end of the spectrum of X-ray light.
