"but to fund our trips into space at ALL the public needs to see people up their."I challenge you to get a single person on the street to name an accomplishment achieved aboard the space station. On the other hand, ask them to name any accomplishment achieved in space since the moon landing and virtually anyone will cite the pictures obtained by robotic craft. I am interested to see if anyone here can cite an accomplishment from the ISS other than space endurance. Meanwhile, we have spectacular successes at Saturn, Jupiter, Mars and the Sun. We've collected material from comets, peered into the beginnings of the universe in a wide range of spectra, and there are plans for many more worthy missions. Believe me, NOBODY was more inspired by manned space flight than me, but we get more for our dollars doing it without people aboard.
Alright here's the dealio:1. Freefall - you get about 10 seconds of near weightlessness before you hit terminal velocity. At terminal velocity the air is putting just as much force on you as the ground would and so you most definitely feel your weight.2. Those zer-g planes - these follow a perfectly parabolic arc for 30 seconds before they have to pull up. For those 30 seconds it is just as good as outer space. The only difference is that the arc in space puts you in a stable orbit while the arc in the plane would hit the ground.As far as the "there is no place where you are weightless" : Weight is defined as the normal force of the ground on you. If you feel no normal force then that is weightless. There will always be gravity acting on you but you can be weightless in any gravitational field by accellerating only along the field lines (falling).

god, that guy is one horrible narrator

@bairy.. skydiving.. MUCH cheaper.. and probably more exilerating.. even though the zero-G is alot different with a ton of wind hitting you

Hmmm, zero-G wet t-shirt contest. Now that's something I wouldn't mind paying some extra tax dollars for.

There can be only one. One bubble will dominate!

A simple chemical reaction created a dynamic bipolar cyst system - looks very similar to watching single cells duplicate in biology....
