How intensively were microbiomes monitored during this study?

Were there any surprising or significant changes in these microbiomes over time and especially after Scott returned to Earth that are worth mentioning?

Thank you for your response, Dr Vitaterna!

How surprised were you and the team when no decline in microbiome diversity was observed as Scott was in such a secluded and controlled environment? Were any preemptive steps taken to ensure Scott's microbiome would remain intact during the flight?

What changes were associated with the mentioned shift?

Also were there any significant changes related to the viruses Scott was carrying such as his total viral load?
