Just read at MSNBC that a large U.S. spy satellite will hit Earth by the end of February or early March.
Better keep our hard hats ready??? Here is the article: http://www.msnbc.msn.com/id/22857051/ |

Ahh, I'm chemically illiterate...I meant N2H4, of course, thanks, mchan!
Yeah, Ed, I'm not advocating trying to do without hydrazine; can't see any other practical alternatives either. What's needed is a way to dump the stuff safely from a dead bird, which implies a passive method, presumably triggered by reentry heating. Perhaps high-threshold (500 deg C)/high-volume bimetallic dump valves hooked directly to the tank, similar to what I proposed for on-orbit dead booster venting awhile back? -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

This situation is rare. It is not worth the effort to mitigate this nonproblem |
