I have nothing against rovers or robotics but as I said earlier in this thread If humans don't go in the end it really doesn't matter.
am willing to take the wager , do we have a time limit , say 2030 ?
F-14D said:Of course, it would be seven years at best before that replacement rover arrived, even ignoring the rather poor record of landers actually making it to Mars ,whereas the human would fix such a problem in an hour or two. Back to my point: if all you want is the very limited stuff a rover can do, then it's foolish to send a human. But if your needs start getting more sophisticated, you approach and pass the cost of sending humans.
Mars Polar Lander and Deep Space 2 are one mission/spacecraft. Deep Space 2 were probes/instruments.prolific1 said:Of the four failed NASA Mars Missions two were landers (Mars Polar Lander and Deep Space 2) and two were orbiters (Mars Observer and Mars Climate Orbiter).

Sure. Considering that's 20 years away...where is the infrastructure to make it a reality?
... That said, the ability to fund such a mission would require a full [economic] recovery very soon to even begin to plan such an optimistically timed mission. ;D
Britain’s nuclear waste could be used to power spacecraft as part of government attempts to offset the huge cost of the atomic clean-up by finding commercial uses for the world’s largest stock of civil plutonium.
A £1m pilot programme by the European Space Agency has shown that nuclear batteries for use on deep space missions could be made from an isotope found in decaying plutonium at the Sellafield waste storage site in Cumbria.
Britain’s National Nuclear Laboratory has harvested americium-241 from the plutonium, produced from reprocessing fuel.
The ESA believes this could replace plutonium-238, only available from Russia and the US, and provide an independent source of energy for planned deep space missions to Jupiter and other distant planets.
Tim Tinsley, who manages the programme for the NNL, said the space battery was an unforeseen benefit of past inaction, which has left 100 tonnes of plutonium in ponds at Sellafield.
“It is available due to a twist of fate,” he said. “We have been able to extract that americium and prove that it works.”
Full-scale battery production would be “worth hundreds of millions of euros” and provide skilled jobs in west Cumbria, an area of high unemployment, he said.
Nuclear batteries – each containing about 5kg of nuclear material – have been around since the 1950s and are used in Nasa’s Cassini and Voyager probes as well as Curiosity, which landed on Mars in August.
