It makes him "...very angry, indeed."

Has there been any mention about going to find the other landing sites on mars with curiosity? I know it would be a difficult task but an awesome one none the less

Serious question: Did a bunch of hippies name the rovers?

Just a question,
What’s the difference between this new rover and the other two rovers that are on Mars?

As I understand it, the new one is bigger, nuclear-powered, and has a more capable array of scientific instruments.

The other two rovers are the size of a small desk, battery powered with solar as it's recharge, and had a very limited assortment of science onboard. this one is about as big as a Polaris Razr Side-by-Side, is also battery powered but is nuclear recharged AND HEATED (the rovers were electrically heated which didn't make a whole lot of sense), and this one has a science payload that is a few steps short of a full laboratory. That and the arm that's on this one can articulate to reach anywhere on the rover.
This new one is quite the leap forward for Mars biological exploration. I expect good things from this.

There are a few You Tube videos that deal with the differences, but found this...
Quote:
Some major differences are:
- Curiosity uses nuclear energy, so the problems associated with trying to warm batteries at -238(F), rely on solar power or navigate interesting terrain in the shadows disappear.
- Previous rovers were really only equipped to look for the presence of ice/water. This one is a moving laboratory, including:
- A full gas chromatograph mass spectrometer capable of processing environmental samples on site and searching for chemical compounds, in addition to looking at isotope ratios to determine whether fractionation in major elements was caused by life, or fractionation of water suggests life in the past
- An XRD (x-ray diffraction), XRF (c-ray fluorescence) and XRS (s-ray spectrometer) built in to the arm will determine what elements are actually constituting the minerals it's analyzing, so we can move from a "looks like x" to a "definitely x" state in terms of minerology
- A super high resolution camera with the capacity to make out very fine details and structures on surfaces. Another camera, mounted at human eye-height, can take high res stereo color photos and give another angle on materials being processed
- A radiation detector
- A laser and cross-beam that can vaporize targets from a few meters away and quantify the contents of the dust to determine which areas to investigate
- Sensors for atmospheric temperature, pressure, humidity, winds and UV levels
- A sensor that measures subsurface hydrogen content up to meter in depth
- A host of tools to pick up, open, manipulate, drill in to, sieve sort over filters, and otherwise engage with the samples it's collecting
- The rovers were fragile compared to the cyclopian landscape of Mars, and researchers were constantly afraid of flipping them over, or getting them stuck because of the communications delay, and thereby ending the mission. Curiosity is substantially larger and built for rugged terrain, so they can run it around the most interesting features of Mars they want to investigate without fear of dust, violent temperature changes or losing sunlight.
