NickDG 23 #1 August 2, 2010 Not really! But Julia and the rest of the team at JPL have been working their butts off day and night running mission simulations (to work out the bugs) and tonight they landed on Mars for the first time without any glitches. Now the only thing to worry about is everything else connected with space flight, LOL . . . But Curiosity is a go! MSL mission page is here: http://marsprogram.jpl.nasa.gov/msl/ Also, if you want your name on Mars on a microchip installed on Curiosity go here and fill out the info! http://marsparticipate.jpl.nasa.gov/msl/participate/sendyourname/ NickD Quote Share this post Link to post Share on other sites cocheese 0 #2 August 2, 2010 Dude, I'm going to Mars.

Quote Share this post Link to post Share on other sites billvon 3,119 #15 August 2, 2010 >Longer freefall (more working time), more time to deal with a mal... Hmm . . . Gravity on Mars is 60% of Earth's, but air density is .4%. A jumper who has a terminal velocity of 120mph on Earth would have a terminal velocity of 600mph on Mars. So if you had a mal at 2000 feet you'd hit the ground 2.2 seconds later. A freefall from 12,500 feet would result in about 14 seconds of freefall assuming you started at terminal velocity. However, the "hill" would last a lot longer; you wouldn't even reach terminal velocity before opening altitude. So your actual freefall time would be closer to 32 seconds assuming an opening at 2000 feet.

If you go by how fast atmospheric pressure falls off, it's actually about 80% thicker due to the lower gravity. But because the pressure is so low to start with, that's not saying much. The entire atmosphere of Mars is like our atmosphere above 100,000 feet. BTW one of the more interesting ideas for living on Mars is to use some sort of automated digging system (or some very large thermonuclear bombs) to create a hole about 10 miles deep. At the bottom of those holes you'd see pressures of around 16% of Earth normal - which is enough that you would not need a pressure suit, only an oxygen mask and warm clothing. Likewise you could live in a (plastic) tent as long as you had an oxygen source. Plants would also do fairly well with only plastic over them, similar to the way we grow strawberries here. Since temperatures increase as you go down on Mars as well, it would also be considerably warmer down there - on the order of 50 to 80F if positioned near the equator. You'd have tremendous convective activity as well, which would create weather, although it would still be way too dry to rain.
