Being up in space for an entire year is a LONG time. Have you noticed any effects on your body from weightlessness? Are your plans for recovery once you're back on earth more intensive than traditional programs for other astronauts who only go up for shorter time periods?

With the discovery of water, coupled with the fact that we also know of organic compounds like methane on Mars, how much has the probability of discovering life increased?

My guess would be the radiation. Just a guess though.
