Yes, thats right.. my freind David Mestre ,Director of Space Science Education at the Discovery Museum and Planetarium put a samstone in a satellite built by students as part of the spacegrant program. I'd given him the samstone at the gathering of the vibes music festival in 2012.  I saw david at this years gathering of the vibes (2013) and he gave me the stone and told me the story.. You can read about it here . The samstone and the rest of the payload went up about 62 mils and left the earths atmosphere, then hurtled down back into the Atlantic ocean 42 miles offshore. It was recovered by a ship which followed a radio beacon in the payload. 

 How amazing is that ?
