Zero G can be simulated by dropping an object and then accelerating it back to the top a super high g. If you go fast enough biological samples, etc dosent notice the high g.<br><br><div class="gmail_quote">On Tue, Oct 2, 2012 at 7:45 PM, Alex Cureton-Griffiths <span dir="ltr"><<a href="mailto:alexcg@gmail.com" target="_blank">alexcg@gmail.com</a>></span> wrote:<br>

Maybe instead we could buy a drone/RC plane and have it do parabolas just like the big nasa 747 does. Or if we do go the balloon/kite route maybe have a big spool of monofilament tethering the falling capsule to the balloon/kite, so that when it falls x-distance its fall is stopped. It could then either be spooled by up by a motor on the balloon/kite for another drop, or it could cut itself loose and deploy a parachute. Something like a Helikite (<a href="http://www.helikites.com/" target="_blank">http://www.helikites.com/</a>) could be perfect, allowing a decent sized payload to be raised up very high and dropped multiple times.<br>

How about making and demonstrating a miniature microgravity 'generator' to allow DIY testing of things in microgravity on earth. It would be pretty easy and cheap and would open space research to the masses by allowing short duration generation of microgravity conditions. It could be a weather-balloon-dropped capsule or something with cameras build into the inside to allow observation of whatever short duration experiment one is interested in. This is a relatively quick and easy project that would help attract attention and funding, while also facilitating hackerspaces in doing their own future experiments. <br>
