Zdecydowano, ze Europa wysle tego blizniaka sondy Mars Express rosyjska
rakieta Sojuz Fregate, ktora tak dobrze sprawdzila sie przy starcie tego
ostatniego. Sonda bedzie badac atmosfere Wenus.
Co ciekawe: Na kosmodromie europejskim w Kourou (Guiana Fr.) ma zostac
zbudowane stanowisko startowe rakiet Sojuz. (Oznacza to zapewne, ze jesli
rakiety Ariane nie sprawdza sie w najblizszym czasie, Europa
najprawdopodobniej zrezygnuje z nich na rzecz technologii rosyjskiej.)
Na luty 2004 (ze stycznia 2003) przelozono start Rosette, ktora ma zajac sie
badaniem komety Churyumov-Gerasimenko (z ladownikiem wlacznie). Ma ja wyniesc
Ariane-5 G+ . Koszt tej misji to ponad 700 mln Euro (wraz z rakieta). Trudno
dzis wykluczyc, czy i w tej misji ostatecznie nie zostanie wykorzystany
Sojuz, zwlaszcza ze kolejna alternatywna data startu to luty 2005.

On 17 June 2003, David Southwood, Director of Science for the European Space
Agency, and Jean-Marie Luton, CEO of Starsem, signed the contract of the
Venus Express.
This announcement comes soon after the decision by European space ministers
to build a Soyuz launch pad at Europe’s Spaceport in Kourou, French Guiana.
Starsem is the Soyuz Company, bringing together all key players involved in
the production, operation and international commercial marketing of the
world’s most versatile launch vehicle. Shareholders in Starsem are
Arianespace, EADS, the Russian Aviation and Space Agency and the Samara Space
Center.
The launch of Venus Express will take place in November 2005 from the
Baikonur Cosmodrome in Kazakhstan. The Soyuz launch vehicle will send the
spacecraft on its way towards our nearest planetary neighbor.

Venus Express is scheduled for launch from the Baikonur Cosmodrome in
Kazakhstan during November 2005. It will be carried into space by a Soyuz-
Fregat rocket and placed immediately in its transfer orbit to Venus. Its
journey through space will last 153 days. Once it is captured by Venusian
gravity, Venus Express will take 5 days to manoeuvre into its operation
orbit, looping around the poles of the planet. At its closest, it will reach
an altitude of 250 kilometres and at its furthest, it will be 66 000
kilometres away from the planet. The mapping mission is due to last for 2
Venusian days, about 500 Earth days.
