    Results of measurements with the Planetary Fourier Spectrometer onboard Mars Express: Clouds and dust at the end of southern summer. A comparison with OMEGA images

    We discuss the results of measurements made with the Planetary Fourier Spectrometer (PFS) onboard the Mars Express spacecraft. The data were obtained in the beginning of the mission and correspond to the end of s...

    Phyllosilicates on Mars and implications for early martian climate

    The recent identification of large deposits of sulphates by remote sensing and in situ observations has been considered evidence of the past presence of liquid water on Mars. Here we report the unambiguous detect...

    Release of volatiles from a possible cryovolcano from near-infrared imaging of Titan

    The surface of Saturn's largest moon, Titan, is coated in a dense methane-rich atmosphere that prevents high-resolution imaging at visible wavelengths. During its first Titan flyby last October, the Cassini sp...

    Compositional maps of Saturn's moon Phoebe from imaging spectroscopy

    Phoebe, the outermost large satellite of Saturn, is of particular interest because its unusual orbit suggests that it was gravitationally captured by Saturn, having formed outside the solar nebula where Saturn...

    Irradiation Effects in Ices by Energetic Ions

    It has been shown that the irradiation of ices leads to “giant” erosion yields, in some specific conditions (1,2). In order to understand the physical processes involved, we have performed direct in-situ measu...

    Detection of parent molecules in comet P/Halley from the IKS-Vega experiment

    Several parent molecules have been detected in comet P/Halley using the 2.5–5 μm channel of the IKS experiment aboard Vega 1. The spectral resolving power was about 40 at 2.5 μm and 70 at 5 μm. The v3 band of H2O...

    Temperature and size of the nucleus of comet P/Halley deduced from IKS infrared Vega 1 measurements

    The infrared thermal emission of the nucleus of Halley’s comet was measured by the imaging channel of the IKS spectrometer in two wavelengths bands (7–10 µm and 9–14 µm) and in two perpendicular directions of ana...
