Venus Express to pierwsza europejska sonda Wenus (po Marsie, Tytanie i
Księżycu, to czwarty obiekt w Układzie Słonecznym, do którego podąży
europejska sonda). VE ma wejsc na orbitę Wenus w kwietniu 2006 r. i zając się
badaniami atmosfery tej planety pod kątem efektu cieplarnianego.
Ma dostarczyć ilosciowo więcej danych niż wszystkie poprzednie misje razem
wzięte (nie licząc Magellana) - 500 Mbitów danych dziennie.
<<Venus Express is due to lift off from Baikonour on 26 October. A Soyuz
launcher will place it on a parking orbit around Earth and then the rocket's
upper Fregat stage will send the probe on its 126-day journey towards Venus.
(...)
"For instance, we may understand why this planet has such a huge greenhouse
effect with surface temperatures some 470 degrees Celsius, or why the planet
rotates in the opposite direction to Earth and so slowly, taking 243 Earth
days to complete one revolution."
Venus was the first planet to which a probe was sent, back in 1962. Up until
the early nineties and NASA's Magellan radar reconnaissance orbiter, some 20
different spacecraft have gone there, several even landing and sending back
pictures of its surface before they melted under the heat.
Venus Express will be making the first global examination of the atmosphere
of Venus. It will analyse its thick, sulphuric acid laden clouds, and search
the surface below for signs of active volcanoes.
The scientific teams of the seven very precise instruments and multi-
wavelength cameras on board expect to collect infinitely more science data
than all previous missions combined - with the exception of Magellan – more
than 500 megabits of data received every day.>>
