Today's question from Jacob was also submitted as a comment yesterday by Teresa:

What projects are being worked on during your trip to the ISS?
- Jacob (Team Apollo)

MAGNUS: We always have science experiments going on and that keep us busy, but during this stay on board the ISS we are also going to be installing the equipment needed to support a six person crew. We currently have a crew of three people on board, but next summer that will increase to six. We recently delivered an extra toilet, some crew quarters (bedrooms as it were), extra exercise equipment and most importantly the water regeneration system. This system allows us to process all waste water on board, including urine, and make potable water out of it. My fellow Expedition 18 crew mates and I are installing all of this equipment and getting it running. We need to get some testing done on it to make sure it is working properly prior to increasing the crew size.

P.S. Keep watching the blog for more answers to questions like...What's it like to sleep in space?
