Could Mars Rover Curiosity Infect Mars?

[Persia]

During the run up to the launch of NASA's Mars Science Laboratory (MSL) Curiosity on Nov. 26, a step in the "planetary protection" procedure wasn't adhered to. The procedure's key purpose is to make sure organic material from Earth doesn't get transferred accidentally to another planet -- in this case, Mars.

I thought the whole point of spending billions of dollars on researching Mars is so we can use it to grow more corn on build 7-Elevens etc.

I myself am saving up now so I can spend a vacation there by 2024 I hope.
