The Russians are more optimistic:
Refusing to be deterred by a string of failures in exploring Mars, Russian space officials have proposed an ambitious international project to send a six-person team to the Red Planet around 2015.
Russia's space programme hopes to work closely with the American agency NASA and the European Space Agency to build two spaceships that would be capable of transporting the crew to Mars, supporting them on the planet for up to two months and then safely bringing them home, said Nikolai Anfimov, head of the Central Research Institute of Machine-Building.
The roughly 440-day trip — which would mark a milestone in space travel and international space cooperation — is expected to cost about $20 billion, with Russia suggesting it would contribute 30 per cent.
``It must be an international project,'' said Vitaly Semyonov, head of the Mars project at the M.V. Keldysha Space Research Centre. ``No one country could cope alone with this task.''
Russian space officials said they are receiving encouraging signs of interest from NASA and European counterparts.
