Space Forum / Shuttle / January 2008next shuttle launch... TBD
wisely they are disassembling the ETs sensor connector in the hopes of identifying the root cause of the flakiness. lets hope they can say for certain whats up........ the worst case is taking everything apart and finding it all looks perfect, only to have more bad readings at the next tanking. I am just glad to see they are taking the time to do it right, and not telling the computers to ignore the sensors! effectively strapping them out...... The thing is I think that if we are really serious about basing people on Mars in the future, extreme environments and extended life of components is very important. My feeling here is that corrosion and thermal expansion and contraction play a big part in this when you couple it to the very very small currents in the system. Strange things happen at very low currents through connections.

Having said that: I am betting that the problem is the male connector inside the tank. Seems to me that the super cold would cause the diameter of those pins to contract and become intermittant, if the problem is, in fact, the connector. We shall see. I just want to see her fly; safely, of course. Regards, Jim in Houston |
