Externet Posted March 11, 2009 Share Posted March 11, 2009 Imagine an extremely buoyant balloon rises vertically to -say stratosphere- , and stays up there; Could it be called being in a geostationary orbit ? -Ignore winds- Link to comment Share on other sites More sharing options...
YT2095 Posted March 11, 2009 Share Posted March 11, 2009 it would certainly be geostationary, but it`s not really an Orbit. Link to comment Share on other sites More sharing options...
Externet Posted March 11, 2009 Author Share Posted March 11, 2009 And a true geostationary satellite, would not really be in orbit ? Link to comment Share on other sites More sharing options...
insane_alien Posted March 11, 2009 Share Posted March 11, 2009 no, a true geostationary satellite would be in orbit. a balloon in the upper atmosphere however, is not in orbit anymore than you are when you're standing still. Link to comment Share on other sites More sharing options...
Sayonara Posted March 11, 2009 Share Posted March 11, 2009 no, a true geostationary satellite would be in orbit. a balloon in the upper atmosphere however, is not in orbit anymore than you are when you're standing still. What about when he jumps a bit? Link to comment Share on other sites More sharing options...
insane_alien Posted March 11, 2009 Share Posted March 11, 2009 sub orbital trajectory at best. Link to comment Share on other sites More sharing options...
Sayonara Posted March 11, 2009 Share Posted March 11, 2009 What if he jumps a bit facing in the opposite direction to the Earth's rotation while holding a balloon, on a trampoline? Link to comment Share on other sites More sharing options...
YT2095 Posted March 11, 2009 Share Posted March 11, 2009 He`d look silly? BUT WHAT FUN!!! Link to comment Share on other sites More sharing options...
Sayonara Posted March 11, 2009 Share Posted March 11, 2009 Maybe he could rub the balloon on the carpet until it acquires enough static to adhere to the firmament. Link to comment Share on other sites More sharing options...
YT2095 Posted March 11, 2009 Share Posted March 11, 2009 actually, Joking aside, a Balloon That high up and tethered Would build up a substantial electrostatic charge. I`v done it with a simple longwire up a tree (a makeshift SW radio antenna), and it`s quite capable of lighting a neon bulb (90v trigger voltage), or Fluorescent tubes under certain conditions.

Sisyphus Posted March 11, 2009 Share Posted March 11, 2009 the opposite direction to the Earth's rotation Usually we just call that "west." Link to comment Share on other sites More sharing options...
dirtyamerica Posted March 28, 2009 Share Posted March 28, 2009 the floating balloon is buoyant and geostationary in your example. Objects in geostationary orbits are falling at the same speed as they are traveling forward (for a lack of a better description). Link to comment Share on other sites More sharing options...
