		<description>Yes, we need more space debris.</description>

		<description>That said, given the height that those cameras on balloons get, could you build a 2 stage balloon + rocket to get you to a stable orbit?  I suspect not, otherwise it would have been done already.</description>

		<description>These ultra-LEO (Low Earth Orbit) satellites barely qualify as debris. The orbit probably decays on the order of months. 

After a bunch of searching, I found this on his site: &lt;i&gt;I&apos;m doing music from space, using a 200 gram instrument in a half-kilogram case launched 312 kilometers up. What 200 grams would you put into orbit?&lt;/i&gt;

A little more googling turned up &lt;a href=&quot;http://www.ips.gov.au/Category/Educational/Space%20Weather/Space%20Weather%20Effects/SatelliteOrbitalDecayCalculations.pdf&quot;&gt;this paper on an orbital decay rate simulator&lt;/a&gt; which happens to have a sample run for a 300km orbit on page 5. Decays after 46 days.</description>

		<description>Does fluoride fight orbital decay?</description>
