      I study quite a few, but the main one is Sphingomonas desiccabilis. It’s an incredible survivalist – its normal home is the desert, so it survives extremely hot and dry conditions during the day and extreme cold at night. It can be dried down for weeks and revived without a problem, so it’s perfect to send up to ISS. Especially since launch windows can change or other delays can pop up with a mission, so my organism is happy to chill while launches are rescheduled. S. desiccabilis also mines rock for essential elements, like iron, so it performs a useful task that we’d like to know more about in space.
