NASA's Amy Fisher

Sure, this might be a reach. Though we'll be trying to unravel this one for some time. Andrea Peyser takes a crack at it.

ON EARTH, Lisa Nowak masqueraded as a brilliant rocket scientist, wife and mother of three.

But the diaper-wearing wacko-naut went into orbit - transforming into a scary, yet strangely familiar, creature.

She is the Amy Fisher of the space program.

This widely accomplished space lady, nicknamed "Robochick" for her skill at handling the space shuttle's robotic arm, turns out to be just another sexually needy, fiercely aggressive wild child. Only this wackjob was armed with pepper spray and - for reasons too icky to contemplate - a rubber hose.

It makes you wonder if NASA should channel Dr. Freud. Or maybe Oprah. Because Lisa Nowak proves two things beyond doubt.

No matter how educated and accomplished a woman is, down below, there can live a murderous teen, equipped with a wicked jealous streak and a hair-trigger temper.

And Lisa has revealed to the taxpaying public the answer to a question that has baffled space-watchers since the Mercury program. How do astronauts deal with space-related incontinence?

Depends.
