Mission Name: Mars ExpressThe Analyzer of Space Plasmas and EneRgetic Atoms (ASPERA), is an ion, electron, and neutral atom analyzer consisting of a neutral particle imager and ion spectrometer mounted on a scanning platform. Its primary scientific objective is to measure the plasma-induced atmospheric escape and the interaction of the solar wind with the martian ionosphere.
ASPERA will measure particles in the outer atmosphere of Mars using four sensors. The sensors will measure abundances of energetic particles, including ions of energy 0.1 to 10 keV, photoelectrons from 5 eV to 20 keV, and energetic neutral atoms from 100 eV to 10 keV. Of particular interest are the abundances of oxygen and hydrogen atoms interacting with the solar wind and the regions of such interactions.
