High resolution IR-spectrometer . ... Determination of concentration of atmospheric greenhouse gases (carbon dioxide and methane) from ground-based or spacecraft platforms. ... Compact eschelle spectrometer is built by autocollimation scheme with diffraction grating operating in high orders of diffraction, allowing thereby to reach the resolution up to ?/ 20 000. ... For observations at the ground-based platforms and aboard the ISS the instrument modification RUSALKA will be used. ...

... Dione's icy surface includes heavily cratered terrain, moderately cratered plains, lightly cratered plains, and whispy material. The heavily cratered terrain has numerous craters greater than 100 kilometers in diameter. ... Much of the heavily cratered terrain is located on the trailing hemisphere , with the less cratered plains area existing on the leading hemisphere . ... Because Dione is relatively small, an impact causing a 35 kilometer (21 mile) crater could have spun the satellite. ...
