Аннотация
Venus Exploration of Volcanoes and Atmosphere (VEVA) is a potential
Discovery mission. It will provide a multidisciplinary investigation
of the atmosphere and surface of Venus by returning the first-ever
aerial photography of the surface and definitive, in situ determination
of its atmospheric composition in the lower scale height. VEVA involves
delivering an entry vehicle to Venus housing a payload consisting
of an instrumented atmospheric sonde and a balloon-gondola system.
After entry, the atmospheric sonde is released to fall to the surface,
and the balloon package inflates, which arrests its descent at a
60-km float height. The balloon carries an instrumented gondola with
battery power for 7 days as it circles Venus. The gondola carries
four small imaging sondes for release and descent to the surface
at different times during the 7-day mission. Data from the sondes
are radioed to the gondola for relay to Earth. (C) 2002 Published
