The apparatus and mission goals of the CORONA all-sky soft X-ray scan are detailed. Proposed for a future ESA spacecraft, attention would be focused on X-ray emissions from the North Polar Spur, the Gemini Monoceros region, the Eridanus hot spot, the Lupus loop, and other extended objects. Spectra in the 0.1-1 keV interval produced by plasmas in the 500,000-5,000,000 K range would be examined with two Bragg spectrometers and a concentrator connected to a moderate resolution spectrometer. A low equatorial orbit would permit an all-sky survey with the Bragg spectrometers in 4 mo using 500 10,000 sec pointings and 16 deg segments. Several surveys would be carried out in a 2-3 yr interval.
