The interaction of the solar wind magnetoplasma with the exospheres of the unmagnetized terrestrial planets, Venus and Mars, creates a bow shock and a so-called induced magnetosphere. For this current project, the ULF wave power in the magnetosheaths of Venus and Mars will be investigated. Both specific wave modes (e.g. mirror and ion cyclotron) and low-frequency turbulence will be studied as well as a possible difference in the behaviour of the bow shock for solar minimum and solar maximum conditions. The interactions of Venus and Mars with the solar magnetoplasma differ because of the different radii and distances from the Sun. The differences and similarities will teach us not only something about Venus and Mars, but the results will be generally applicable for other planets (even magnetized ones) and comets.
