Space Shuttle Booster Recovery

Fri Mar 22, 2013 3:45 am

I've seen a couple videos with recovery crews getting the SRBs from the Shuttle but I always found it interesting that they float. I have to imagine they weigh quite a bit. What makes them so buoyant? Is it just because the tanks are empty of fuel? I noticed they would pump water out of the nozzle so I'm not too sure if it could really be just the empty tanks.
Thanks!

Here's a good explanation, straight from the source: http://science.ksc.nasa.gov/shuttle/technology/sts-newsref/srb.html

Excerpt: Water impact occurs 295 seconds after separation at a velocity of 81 feet per second. The water impact range is approximately 140 miles off the eastern coast of Florida. Because the parachutes provide for a nozzlefirst impact, air is trapped in the empty (burned out) motor casing, causing the booster to float with the forward end approximately 30 feet out of the water.
