How is it in space. And how do you guys stay up there that long. The average is 6 months not 365 or more

I think this is crazy that they made it to Mars. I learned that they explored for 1 hour and 12 minutes which is really long. How long did it take to get there?

I think that's really cool and I love are new technology

Know if I go in space I'll know to bring a towel or a hanky

Wow that's really cool, I didn't know that in zero gravity tears can form normally. But i still have one question why do the tears join together and form one, why don't they just fall to the ground like normal.
