“As when astronaut Mike Mulhane was asked by a NASA psychiatrist what epitaph he'd like to have on his gravestone, Mulhane answered, "A loving husband and devoted father," though in reality, he jokes in "Riding Rockets," "I would have sold my wife and children into slavery for a ride into space.”

“NASA might do well to adopt the Red Bull approach to branding and astronautics. Suddenly the man in the spacesuit is not an underpaid civil servant; he's the ultimate extreme athlete. Red Bull knows how to make space hip.”

“I will tell you sincerely and without exaggeration that the best part of lunch today at the NASA Ames cafeteria is the urine. It is clear and sweet, though not in the way mountain streams are said to be clear and sweet. More in the way of Karo syrup. The urine has been desalinated by osmotic pressure. Basically it swapped molecules with a concentrated sugar solution. Urine is a salty substance (though less so than the NASA Ames chili), and if you were to drink it in an effort to rehydrate yourself, it would have the opposite effect. But once the salt is taken care of and the distasteful organic molecules have been trapped in an activated charcoal filter, urine is a restorative and surprisingly drinkable lunchtime beverage. I was about to use the word unobjectionable, but that's not accurate. People object. They object a lot.”

“The suffix 'naut' comes from the Greek and Latin words for ships and sailing. Astronaut suggests 'a sailor in space.' Chimponaut suggests 'a chimpanzee in sailor pants'.”

“To the rocket scientist, you are a problem. You are the most irritating piece of machinery he or she will ever have to deal with. You and your fluctuating metabolism, your puny memory, your frame that comes in a million different configurations. You are unpredictable. You're inconstant. You take weeks to fix. The engineer must worry about the water and oxygen and food you'll need in space, about how much extra fuel it will take to launch your shrimp cocktail and irradiated beef tacos. A solar cell or a thruster nozzle is stable and undemanding. It does not excrete or panic or fall in love with the mission commander. It has no ego. Its structural elements don't start to break down without gravity, and it works just fine without sleep.To me, you are the best thing to happen to rocket science. The human being is the machine that makes the whole endeavor so endlessly intriguing.”

“No one is excluded from the astronaut corps based on penis size.”

“With the rise of classical Greece, the soul debate evolved into the more familiar heart-versus-brain, the liver having been demoted to an accessory role. We are fortunate that this is so, for we would otherwise have been faced with Celine Dion singing "My Liver Belongs to You" and movie houses playing The Liver Is a Lonely Hunter. Every Spanish love song that contains the word corazon, which is all of them, would contain the somewhat less lilting higado, and bumper stickers would proclaim, "I [liver symbol] my Pekingese.”
