nothing much again

Why is it that nasa has spent so much time and money on mars exploration and they never find anything astounding (in my opinion)? Where's the life? Send people allready then something will be found.

Depends what you consider 'astounding'. If one shapes their expectations around scientific curiosity you may be very happy, if one judges by the range of subjects in science fiction you may well be disappointed.

Aspects of the lower elevation pits near Curiosity look much like the larger crater/layering of the area just north of Valles Marineris, such as Hydrae Chasma, at about -6 Lat and 298 Long.
The similarities are especially interesting as the areas both are in the transition between the Highlands and the northern Lowlands.
Following this change of landscape at areas a half a hemisphere apart gives a pattern of geology or weather or global activity which is still in questions as much as answers.
Finding life in a hostile environment would be a difficult task by expectation. The other answers are becoming more clearly written in images.

A better view of Hydrae Chasma layering in lows.

We have water courses in Gale crater and possibly in this other area north of Valles Marineris as well.

NASA is driving a 1 ton rover on a planet millions of miles away. Producing outstanding pictures. In fact these pics alone to me are well worth their limited budget. Their details are amazing, and provide tons of data to scientist. Just read the posts here and you'll realize how much info it can be extracted from pics alone. Not to mention the fact that the current pics are so fantastic... It's like we are there!

Have you seen all the images??? Curiosity was in the middle of a frigging river, that was there, knee-deep, for an extended period of time! There are so many weird rocks/other stuff there... The place look like alive!

And on top of all that, the rover will perform multiple scientific experiments.

All this with a very very small budget.

Frankly, and no offense, I think the problem is that too many people don't recognize the beauty and awesomeness of this. They are asking the question "how does this help my life" where the real question they should ask is "how can I help accomplish this mission and have more missions"
