Will the space shuttle Endeavor be in jeopardy on its return flight to earth?
Pieces of foam came off the large fuel tanks and smashed into the bottom of the shuttle damaging the space tiles. Repairs will have to be made.
Funny, this is a common problem on the space shuttle. THE FOAM KEEPS TEARING OFF THE FUEL TANKS BECAUSE NASA CHANGED THE ADHESIVE IN THE FOAM SYSTEM FROM A SOLVENT BASED PRODUCT (THAT DEPLETES THE OZONE???) TO A WATER BASED PRODUCT. WHY? BECAUSE IT WAS MANDATED BY THE EPA BECAUSE OF THE OZONE DEPLETION LAW THAT WAS PASSED IN CLINTON/GORE REIGN.
This CHANGE was responbible for the Columbia shuttle to crash and kill its occupants on the return flight to earth. Foam coming off the fuel tanks and slamming into the heat tiles on the bottom of the shuttle during take off. This action of foam damage had never happened before on all the other shuttle space mission.
Unfortunately, it was too late for the Columbia crew. The damage to the heat tiles was severe enough therefore, the Columbia was not protected on re-entry into the Earth's atmosphere. BOOM and the Columbia was history.
The Columbia's shuttle crew had to die to prove that a water based foaming system failed over a solvent based foam system?? What a waste of gifted people and expensive equipment.
A big question? How stupid can we be? Uhhh, as important as our astronauts are and as important as the space shuttle is, WHY NOT CONTINUE TO USE THE SOLVENT BASED FOAM INSTEAD OF THE WATER BASED FOAM? Another big question? How much will the ozone layer be affected by the amount of solvent used in the foaming system to cover the fuel tanks? Bet it is low enough amount to justify using the solvent system. NASA needs to get the EPA to give a special variance to be able to go back to the old foaming system.
Since the foam system was changed to a water based product, there has been an issue with the foam coming off and slamming into the shuttle's under side on every shuttle mission. Duhh, how hard is this to figure out? If your son or daughter were going to fly on the space shuttle, would you want to have the best system available to apply the foam to the fuel tanks to prevent another Columbia disaster????? As John Stossell says: "GIVE ME A BREAK".
