This certainly is not the first probe or rover to be sent to Mars, but for some reason, it seems like it to me. Perhaps it is due to the very intricate landing – which went off without a hitch, or perhaps it is simply due to the internet these days. Information and photos are available worldwide the very moment they are uploaded. I believe – with me, anyway – it is a combination of both. I have been completely enthralled with Curiosity and look forward to years of data sent back to earth.
