Phase 4: Balancing Act
 
 

Some important considerations would be how are we going to get water, have fresh air, to keep the dome warm, were to land, how to build and maintain the community, the communication, and how to send people to Mars. These problems were already discussed, but there are other problems. We have to consider that people will be exposed to zero gravity. This carries the risk of deterioration to human muscles and bone tissue. Zero gravity will cause cardiovascular deterioration, decalcification, and demineralization of bones. Other thing that we have to consider is the radiation hazards. There are two ways to send people safe from radiation. One is by using ultra-fast spacecraft, and the other is by using huge spacecraft. Both seem impossible. We have to consider the threat of contamination. We have to make sure to send people healthy, free of any diseases. We have to make sure, too, that we do not bring back to Earth anybody who may have diseases. We can not risk Earth. Other consideration is that the Martian day is 39.6 minutes longer than the terrestrial day. There are three alternatives for our time system. One is by stooping the clock at midnight for 39.6 minutes. The other is by setting our own time units. They would be decimal-based units and we would have decimal-based clocks. The last alternative is having five weekdays of 24 terrestrial hours and having a weekend of 59.55 terrestrial hours.
