The Isolation of Space Travel by Diane Devine

When the first mission to the planet Mars blast off from earth, a crew of at least six people will be confined together for around two and a half years, and millions of miles from home. They will be completely isolated and have only delayed communications with people on earth.  The size of the distance will make real time conversations impossible, on average there will be a forty four minute delay in communications with people on earth.  There is no way to know exactly how this kind of isolation and monotony will affect the crew members psychologically. The longest amount of time anyone has been in orbit has been fourteen months. We know from past missions that space travelers have rated the experience of space travel as a positive one that gave them a new appreciation of life and the planet earth. The astronauts from earlier missions have said that one the most positive parts of their experience was gazing through space to look at earth. This was the one thing that was rated the highest in making the space travelers feel better.  The Mars mission will be the first time that humans have ever experienced something scientist call “earth out of view” phenomenon.

The space community is concerned that increased isolation will lead to severe homesickness and possible suicidal or psychotic thoughts. Researchers believe that increased training and careful screening will reduce the risk of psychological stress on the crew members. However, it may be that an on board telescope allowing the astronauts to view the earth in real time, will be their greatest link to sanity. Sometimes seeing really is believing.

How this all started

Telescopic Topics is a podcast series developed by Dr. Erin Kraal’s Mission to the Planets (AST 30) general education course at Kutztown University of Pennsylvania.  The two minute segments are designed to bring aspects of planetary science and astronomy into focus, zooming in on interesting and unique views of the world above.  Segments are recorded and aired on campus radio station KUR.
