"Things We Will NEVER Do Again"

James Tomayko
Carengie-Mellon University.


Early in the space program, especially the unmanned side, full redundancy of hardware was commonplace. This incurred large penalties in size, power, and weight, but provided backups where failures were thought to occur often: the avionics. After NEVER, ever needing the backups, this belief has dissipated. Therefore, one thing we would NEVER do again is carry full redundancy. This talk recounts previous efforts aimed at redundancy and current missions without it.
