... an evaluation to make sure you are prepared for your flight. You can't really fail, but you may be required to complete additional training. ---- Answer provided by Tim Bailey & Loretta ...

The electrical system is two-fault tolerant. That means that if one system fails, there are two backups available. While the backup is in place, fault detection isolation and ...

There are different definitions of flight failure. There is mission failure, launch abort, and some failures of equipment on the spacecraft. It depends upon which type of failure is intended. Again, if failure is considered an unexpected occurrence, then those happen all the time without necessarily leading to an adverse consequence. ---- Answer provided by Futron Corporation Image:K2S ...

... started winding up on them. Well, Neil Armstrong was fighting it. He was opposing that failed thruster, and Dave Scott was over there pulling and pushing circuit breakers. By this time ... failure after failure. Oh, that was a nightmare sim day. They just kept failing thrusters and failing thrusters and failing thrusters. Kranz said, "Carlton, what's wrong with you?" Laughter There was nothing ... . Now, what did that tell me? It says there's no thruster failed. If there's a thruster failed, that gimbal would be off in the left corner. There was no thruster ...

... , but that was a brilliant stroke. '''Bergen:''' Apollo 8. '''Chilton:''' Apollo 8. I think I failed to mention that, as I said, during our advanced studies we never thought about landing ... platforms we'd have; whether they would be fail-op or fail-op, fail-op, fail-safe. Fail-op, fail-op, fail-safe or fail-op, fail-safe, or fail-op, fail-op, fail-safe. All those things, I had no contribution ...

... the Moon, and all of a sudden they had had one of the fuel cells fail, hard fail. Then they went on another—still out of contact. Later they ended up having ... continued the rest of the mission with one fuel cell totally failed. Even if we had a second fuel cell fail, we could power down the spacecraft and safely return. So we had what you call fail op/fail safe, or triple redundancy. But if you go to something like the main buses, which ...

... was a much more complicated problem because we needed to have what we call a fail-operational fail-safe system. So you had to have four computers essentially working together in synchronization ... knocked that computer off. But the point being, we had a fault-tolerance system, fail-operational, fail-safe system. So the question was whether we were going to be able to make ... a very sensitive issue. We had had one failure at the test facility where it failed shut. It was held open by the aerodynamic configuration, the hydrodynamic configuration. If that shut ...

... in the space, transportation, nuclear, defense, marine or petrochemical industries. We know afterwards why we failed. In the technology endeavor of new frontier, we observe risky outcomes all the time, and ... , human factors and using sound design practices. (4) Extensive use of "fail safe" and/or "fail operational" philosophy to guard against fatal consequence in case of total system ...

... in specific failures at specific times in the—in their hopes they would make us fail. But that conditioning, through all those hours, certainly made me confident of the team that ... malfunction procedures that were to be used for the command and service module should anything fail or go wrong. So Jack was very versed on the technical aspects of a command ... the first major component in any system—one of the guidance and nav navigation components failed at 8 hours. '''Ward:''' Well this was because, without water you can’t cool it ...

... binding. And then we also had to do the Ku-antenna. It had failed. Its pointing mechanism had failed. If it doesn’t rotate correctly back, then we would have to jettison ... and clevis arrangement. So the joints, in my opinion, are never going to fail. So if it does fail, it won’t be the joint. '''Ross-Nazzal:''' So you’re pretty satisfied ... that you worked closely with? '''Ewart:''' Yes, but this is where my memory starts to fail me. John McCarthy was in charge of quite a number of people, probably about up ...
