Venus/ Planetary Fourier Spectrometerthermal emissionacoustooptical tunable filterwavelength 0.7 mum to 1.7 mumSpectroscopy for the investigation of the characteristics of the atmosphere of Venus (SPICAV) is a suite of three spectrometers in the UV and IR range with a total mass of 13.9 kg flying ...
Venus: slowly rotating cloud over the planet with a huge greenhouse effect. Mars: a thin atmosphere where the weather systems are strongly influenced by the large topography of the surface. Jupiter and Saturn: large fluid atmospheres, rapidly rotating, with internal heating to assist in driving ...

pause) of the magnetosphere beneath Mercury’s surface. Under these conditions solar wind ions would impinge directly on those portions of Mercury’s surface immediately beneath the Sun. Even infrequent occurrences of such an event could dramatically alter the atomiccompositionof surfaceconstituents....
FIGURE 1. Pioneer Venus Orbiter Cloud Photopolarimeter (OCPP) image of Venus at 3650 Å. Within a few years of launch, IUE identified several important trace constituents, including nitric oxide (NO), and confirmed the presence of several others, such as sulfur dioxide (SO2). The Vega 1 ...

The absorbing characteristics of sulfuric acid vapor appear to reconcile what had been thought to be an inconsistency among measurements and deductions concerning the constituents of the atmosphere of Venus, and radio occultation, radar reflection, and radio emission measurements of its opacity. These ...
