Idunn Mons on Venus: Location and extent of recently active lava flows

Helbert, Jörn; D'Incecco, Piero; D'Amore, Mario +1 more

From 2006 until 2014 the ESA Venus Express probe observed the atmosphere and surface of the Earth's twin planet. The Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) has provided data that indicate the occurrence of recent volcanic activity on Venus. We selected the eastern flank of Idunn Mons - Imdr Regio's single large volcano - as the…

Ultra low frequency waves at Venus: Observations by the Venus Express spacecraft

Fränz, M.; Zhang, T. L.; Dubinin, E. +2 more

The generation of waves with low frequencies (below 100 mHz) has been observed in the environment of most bodies in the solar system and well studied at Earth. These waves can be generated either upstream of the body in the solar wind by ionization of planetary exospheres or ions reflected from a bow shock or in the magnetosheath closer to the mag…

Retrieval of Venus' cloud parameters from VIRTIS nightside spectra in the latitude band 25°-55°N

Piccioni, Giuseppe; Grassi, Davide; Magurno, Davide +2 more

Two years of data from the M-channel of the Visible and InfraRed Thermal Imaging Spectrometer (VIRTIS), on board the European Space Agency mission Venus Express operating around the planet Venus, are analysed. Nocturnal data from a nadir viewpoint in the latitude band 25°N-55°N are selected for their configuration advantages and maximisation of th…
