Hi All, At work I had a link that gave the density of the spray-on foam used to coat the external tank; unfortunately at home, I cannot find it on the web. What I *do* remember was that it said the density of the foam was greater than that of styrofoam. I think it said a factor of 5, which seems awfully high. A quick search on line indicates that the density of styrofoam is 30 kg per cubic meter. (I'm sure the figure varies quite a bit depending on what type of styrofoam you're talking about). Assuming the 6" x 16" x 20" dimensions given describe a rectangular block, the corresponding volume is 1.11 cubic feet which is 0.0315 cubic meters. Styrofoam of this volume would then weigh 0.944 kilos, or 2.11 lbs, which is not that different (~25 %) from the 2.67-lb figure they've been reporting. But if the true density is indeed 5 times that of styrofoam, then the actual mass of the debris would be 10 1/2 lbs -- that's getting to be quite significant. Can anyone dig up the density figure for the foam? --Rob ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www.satellite.eu.org/seesat/seesatindex.html
