Not that long ago talking about aliens would get you labeled as a nut case conspiracy theorist,and told to put on your tinfoil hat.

Not that sending a craft to Mars is not cool, It is.
However I'm very confused that they had the technology to send men to the moon 50+ years ago,but somehow all that technology got lost
and they have to reinvent the wheel to get there again.
