NASA is unsure about Mars actual enviroment ie sans any little pesky creatures that might come out at night, etc.

Even with the rovers we dont know, there is three windows of time that NASA can send instructions to the rovers to do stuff. They have an automated program as well but its timed with the same three windows.

Do you think the rovers are "on" and conducting photograph sessions at night ?

They really do not know exactly whats on Mars yet.

What if you send a manned mission to Mars and the lander lands in an area that has a subterreanen "creature" living under it, that is capable of coming to the surface when it detects seismic activity. Hence a giant worm that has no eyes and lives most of its life underground. But could represent a huge threat to a space craft, men etc. We don't know

Maybe a rover will come up missing, its possible, but that's why the rover missions are important to try and do discovery as to the total threat to a possible manned mission. What if the rover gets suddenly pelted with cosmic mico rocks and is severly damaged. What if this happend to a manned lander, making it inoperable and commiting the astronaughts to their deaths. How would the US goverment deal with the questions of why we did not know that could be a threat and be unprepared with a back up plan to get them off Mars.

These are the things that stop NASA from sending a manned mission to Mars right now
