Shuttle Fuel Tank Design.
Isn't is obvious to the most clueless that the tanks to be covered with a hairnet or pantyhose type covering? Surely there are dozens of materials that will withstand the heat and vibration of lift-off NOT reentry..... I would have done that on day one. The idiots at NASA and spent a billion dollars and 2 and 1/2 years and they haven't figured it out yet..... Sherman |

That's exactly why we need government running less and interfering less and
let private sector do what it does best. And just maybe private sector could actually make a profit "Sherman" wrote in message ...

The truth of the matter is they already had a foam that performed perfectly
well with no problems, but stopped using it because it wasn't "environmentally friendly" "Ignoramus27279" wrote in message ...

And do you think that the private sector would do this kind of thing
without govt. subsidies (i.e., without the govt. taking our tax dollars and turning them over to private corporations)? How long do you think it would take for them to see any return for their investment? Is there a law against private exploration of space? If not, then perhaps there isn't any because there's no profit to be made.

You need to look up "The spaceship company" a spin-off of the Virgin group.

The "ODM" material was the foam, not the products of combustion. The foam
was freon based, but it worked and didn't fall off on take off. It was replaced with an environmentally friendly material to appease who knows "Ken Marsh" wrote in message ...

And if the net-like material holds a broken piece of foam close to the tank, the resulting airflow inside the foam may rip off the remaining foam like a cutting jet. This isn't a trivial problem and isn't likely to be solved with a trivial solution. Mike |

The old foam suffered more from problems with ice than the latest incarnation. Ice can cause as much damage to the tiles as can the foam. The fact is that NASA has been relying on luck for a long time. Even going all the way back to the Mercury program, the margin for error was always small. Mike |

Also a service could make a profit. The profit is calculated by how
much money made over what it costs to provide the service. It's how I make my living. To make a profit, you have to get paid for a product.
