They (gov) obviously found something on Mars. What's the justification for sending another rover up to Mars when there's already two up there (one active). Supposedly, one of the rovers has a damaged wheel and is stuck and the other is still trucking it.
This is obviously for another purpose if it even landed on Mars. For all we know those pictures are from some barren desert here on Earth. You just never know nowadays.If they in fact landed on Mars one has to wonder their true agenda.

Great! I can't wait to see some photoshoped images!
The executive director of the CSIRO, Megan Clark, watched the NASA live stream with the US ambassador to Australia, Jeffrey Bleich, and the director of the Canberra Deep Space Communication Complex, Ed Kruzins, at Tidbinbilla. She said she was extremely proud of the Australian team involved in communicating with Curiosity.
''You could see the nerves in the guys at [the Jet Propulsion Laboratory], you could see the nerves in our guys. You wanted everything to go well but you also know that it is an incredibly audacious project,'' Dr Clark said.
''Now we start the next phase and we'll be part of a major science project to collect and transmit the data. This is really just the start of it.''
During the next few days, the Tidbinbilla tracking station will upload the software to Curiosity that tells it to change from spacecraft mode to rover mode so it can spend the next two years trying to analyse whether conditions have ever favoured life.

This will probably sound noobish when it comes to cameras, but you will have to excuse my ignorance. I know its not all about Megapixels, but the main camera is 8 mega pixels while you can buy a 30 mega pixel camera from any consumer store. Plus gigapixel cameras have also been made now. Fair enough the gigapixel cameras are probably just to big to justify it, but surely they could manage more than 8?? Or is it just about photo size, it would take to long to send back to earth if the resolution was so high?
Telecommunications technologies serve as the "walkie-talkies" that enable spacecraft operators on Earth to send commands and receive data faster and in greater amounts. Below are examples of the way in which the Mars Science Laboratory mission benefits from past technological development.
The Mars Science Laboratory Rover will be able to "talk" to Earth using any one of three antennas. During the mission, the rover's primary means of communication will be via UHF frequencies -- similar to those used for television broadcasts. During "conversations" scheduled twice each day, NASA's Mars Reconnaissance Orbiter, now in flight above Mars, will serve as intermediary and record the information for transmission to Earth. Each conversation will last about 15 minutes, the length of time it takes for the orbiter to pass from horizon to horizon. The orbiter will then relay the information to Earth.
In a pinch, NASA's Odyssey spacecraft, also in orbit above Mars, will serve as a backup for relaying information in the same manner. Odyssey has transmitted most of the data from NASA's two Mars Exploration Rovers since they landed on the red planet in 2004. On occasion, the European Space Agency's Mars Express may also serve as intermediary.
The rover has two other antennas for communicating directly with Earth, similar to those used on the Viking landers in the 1970s, the Pathfinder mission in the 1990s, and the Mars Exploration Rovers. One is the Low-Gain Antenna, the other the High-Gain Antenna. Both are similar in appearance to satellite television dishes but transmit signals at much higher frequencies known as X-band frequencies. These higher frequencies can transmit more data in the same amount of time using smaller, shorter wavelengths, but the transmissions must be more narrowly focused to be received at the other end.
The Low-Gain Antenna, transmitting broader, less focused signals, will serve as the rover's primary link to Earth for the first several sols, or Martian days, after landing. These signals will spread out as they leave the antenna, so that no matter which way the antenna is pointed, the signal will reach the Earth. Once mission controllers have determined the rover's precise location and attitude -- that is, which way its various parts are oriented relative to the Sun and Earth -- they will switch communications to the High-Gain Antenna. The High-Gain Antenna sends a more efficient signal focused directly at Earth, to be detected, like all transmissions from Mars, by NASA's Deep Space Network of antennas.
Another way the Mars Science Laboratory rover can communicate is via the Electra experiment on board the Mars Reconnaissance Orbiter. Electra has a very important role in helping determine the precise location of the rover as well as any other spacecraft on or above Mars.
