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/ |

I wouldn't advocate adding more penetrations to a tank; understand how difficult it can be to design those things to hold pressure & pass the structural integrity requirements. (The bimetallic valves I was thinking about would be on the main feed line before the pump & shut-off valve, making it effectively one penetration topologically).
I would, however, really like to know if there's some sort of substance out there that's safe to fly to coat the tanks with, something that might promote intense spot-heating during reentry. I don't know; maybe a layer of magnesium coated with plastic to keep the O2 out pre-launch, or even just a few strategically-placed patches of same? One other thing about such "vent-patches" is that they might blow under some circumstances during a launch failure & dump the crap before it's anywhere close enough to habitable areas to cause problems. -------------------- 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.

1. I wouldn't advocate adding more penetrations to a tank; understand how difficult it can be to design those things to hold pressure & pass the structural integrity requirements. (The bimetallic valves I was thinking about would be on the main feed line before the pump & shut-off valve, making it effectively one penetration topologically). 2. I would, however, really like to know if there's some sort of substance out there that's safe to fly to coat the tanks with, something that might promote intense spot-heating during reentry. I don't know; maybe a layer of magnesium coated with plastic to keep the O2 out pre-launch, or even just a few strategically-placed patches of same? One other thing about such "vent-patches" is that they might blow under some circumstances during a launch failure & dump the crap before it's anywhere close enough to habitable areas to cause problems. 1. It is still a propulsion system penetrations. Also Range safety wouldn't like like them since there is no insight or intentional control of them 2. Since the weight and range safety issues. |
