So you had to be wrong in your very first post. LOL
In all seriousness the main reason we’ve lost so many of the mars probes is the fact that there was no one on board to make corrections in real time.
However there is still no really compelling reason to send men to mars yet. We need better robots doing far more in depth science and covering more ground first.
If we want to send men to space, lets get a continuously manned station on the moon first.
Hey, if a robot can’t be sent reliably, no one in their right mind would get in the thing. Plus, realtime corrections would rely on the computers available, and if a robotic probe doesn’t have a computer good enough, neither would a human. So, I’m right again. [horn flourish]
