"BS: It would be great to hear about any wear patterns that reflect the traces human beings always leave in a home. Hand-written labels, fridge magnets, welcome mats, duct tape, foam padding on metal parts where people bump their heads, posters, decals, wise-cracking graffiti, barracks pin-ups, spittoons, any of that. The human dwelling element. "Life in Space: Email from the ISS
NS: There are several places across the different modules where "human traces" can be found. We all try to make our sleep quarters as homey as possible with pictures of our families and pets and with special things from home: toys our kids gave us to have with us, books, hobby supplies. We as crews have also established traditions for putting crew patches on display; there is a panel in Node 1 with patches stuck to it from every shuttle crew that's ever visited the station. One of my favorite areas that has the human touch is in the Russian Service Module where there is a classic picture of Yuri Gagarin, an Orthodox Russian crucifix, and picture of [Russian space theorist Konstantin] Tsiokovsky. And then there are some of the science experiments that help bring more life to the station: plant growing, mice, protein crystals, Earth observation photography
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
