Let's say that NASA has just put USMS in charge of the swim club at their newly established colony on Mars. The nearest swim meets are several months of travel time and millions of dollars in travel costs away, so they want the club to be entirely self-sufficient. The question is: what sort of programs can be put in place to keep the swimmers healthy, happy and fit? NASA has provided an internet connection that can be used to send materials to the club, what useful resources could be made available?
