Packing for Space – Oh, and Mars, too

packing for marsMary Roach’s book Packing for Mars is not mostly about Mars. This annoys me. It opens hopefully with isolation studies aimed at all space travel, but in particular a mission to Mars; and the last chapter is aimed at Mars. But the subtitle is more accurate: The Curious Science of Life in the Void. The Void is zero-gravity.

Not everyone is annoyed like me. The book gets 4.5 stars on Amazon.

Roach presents the history of the US and Russia in space, from captured Nazi rockets to the International Space Station. She uses her signature method of digging into the gnarly nitty-gritty. “One of the things I love about manned space exploration is that it forces people to unlace certain notions of what is and isn’t acceptable. And possible.” This suits her style.

Zero-g and the human body
Zero-g presents a lot of problems for the human body. Roach is characteristically persistent in her exploration of how bodily effluvia are handled. Some of it is fascinating. Water, and therefore urine, acts very differently in zero-g where surface tension controls its movements. Urine builds up on the sides of the bladder, which fails to warn an astronaut it’s time to pee. The bladder can get so full it squeezes off the urethra and a catheterization is needed to avoid death. Imagine the obituary.

Poop is even ickier.

Space hygiene is an interesting contrast to all the gleaming white rockets and high tech equipment NASA likes to display.

Sex – shush
Sex in space is also explored and, since NASA won’t discuss the subject, Roach turns to marine biologists to learn about underwater mammals. She also includes stories of acknowledged hoaxes and pornography about sex in zero-g. That’s’ funny – for a while.

Sex is one thing and reproduction is another. Space-station research on rats suggests embryos may not be able to implant in zero-g.

What about Mars?
But I wanted to learn about a Mars mission. My ebook edition makes it easy to find all the mentions of Mars – seventy two times, in three clusters of references, within two hundred twenty pages of text. I’d become frustrated and started skimming in chapter four – Really? V-2 rockets and the first (unfortunate) monkeys in space? So counting made me feel better about the book.  Continue reading
