First of all, I would like to say that I am a believer. A believer in the impossible even. I do believe that things are possible and nothing is impossible to achieve. My mind is open to all kinds of possibilities.
The National Aeronautics and Space Administration (NASA) recently sent a 900 kg (2,000 lb) car-sized robotic rover, called "Curiosity" to Mars for exploring the Gale Crater. Curiosity landed successfully on the Martian surface in August 2012. It is a great feeling to know that we are finally landing on other planets now, this being the first step toward the whole idea of us someday being able to move out toward Mars or some other planet for shelter; if need be.
But; did curiosity actually land on Mars? How do we know that which we see, which they are showing us, is actually Mars out there? Is it even out there in space, or do we see images and videos of some place right here?
Just a thought that occurred to me some days after watching how successful Curiosity was moving, as if Mars was asleep! This seems too good to be true.
