warming is overstated, but one thing is for sure the earth isn't getting any cooler. The weather is getting stranger and more unpredictable every year. Is this an aberration or a long term trend? I knew I would get a question in there somewhere.

or they also have to do some maneuvers to control the flight of there ship. I think that whole the space flight is controlled from the base station at NASA. The astronauts just keep sitting inside spaceship keeping there fingers crossed. Are there any sort of lever or switches inside their rockets which can direct their motion I mean as they do in the fiction movies??

I go and click on the Astronomy and space link to answer another question and encounter this:

Why don't you become the first to ask a question instead?"

Just a few moments ago, the category had plenty of questions listed!

OK - so 5 points won't go to waste: How many of you out there think that little space rock is going to smack into Mars on Jan 30, 2008? They just increased the odds of impact to 1 in 25 or a 4% probability while further refinement is possible with continual tracking of that object.
