Unlike other mars rovers, Curiousity isn't solar powered. It's nuclear powered. RTGs (http://en.wikipedia.org/wiki/Radioisotope_thermoelectric_gen...) are not new, but I have no doubt that plenty of refinements went into the process to make this one better and more efficient.
Now what if this is the next fuel source for cars? We could dramatically cut down on our use of fossil fuels. That's pretty world changing.
The automated landing represented a huge engineering challenge as well. Lots of lessons learned can likely be transferred to earthly pursuits. Imagine a rescue helicopter that can automatically fly into dangerous situations and save people. Imagine robots that are faster and more efficient at producing or harvesting food.
Then of course, every time we land on a planet, we get better at it. The earth has a finite surface area. Barring major catastrophes, we'll probably fill it up eventually. If the experiments of today can provide a place for the people of the future to move, I think that will be the biggest contribution.
I should point that while engineering the skycrane was no doubt very difficult, and provided all sorts of lessons and solutions, that if we wanted to develop autonomous helicopters for use on Earth, the best way to do it is infact to develop autonomous helicopters for use on Earth [1] [2].
Interesting points, but I don't believe in next 100 years we will be able to live on Mars, or there will be enough justification to move there and spend trillion to pursue that vision (of course this mission only gets us closer). Not only its still extremely expensive to fly there, further the only way to live there is under the shelter, which would cost hundreds of times more than building something similar on Earth.
One could only hope that down within the further explorations, there will be possibilities to either mine or produce something that Mars' atmosphere is perfect for, and something that would cost much more to accomplish here on Earth. Eventually, possible monetary gains would create entire new industry with trillion poured in. Wonder what Mars atmosphere is suitable to produce.
I was wondering about that nuclear power engine. Is it safe?
Because on the one hand they spend all this effort to make sure all the components that go into space are absolutely sterile, in order to not accidentally contaminate the environment on Mars [this really is high priority to NASA], and on the other hand you fly a nuclear reactor there, without anyone or anything to make sure it's contained in the event it might start leaking or something.
