A Mission to Mars

Have you ever had a dream about traveling to another planet in our solar system? If you have, there is an actual programme that is happening right now, and it hopes to send people to Mars in 2023. Known as the Mars One Mission, it will send a crew of four people on a one-way mission to colonize Mars. Those chosen people will have to be ready to say good-bye to the earth forever, as there will not be a return trip.

For the people chosen, they will have to learn to do many different things. First of all, they will be living the rest of their lives with just a handful of other people, so they all must have personalities that allow them to get along. Second, the living quarters that they will have won’t be very spacious, so they will have to deal with that condition as well. If they feel homesick, they will only be able to communicate with people back on the earth via e-mail and videos and audio sent back and forth. However, there won’t be any real-time communication. Even at the speed of light, communication between the earth and Mars takes about 20 minutes.

Whether the Mars One Mission will actually happen is the big question that a lot of people are asking. There is an enormous skepticism in the science community, and Wired magazine gave the mission a miserable score of two out of ten on its probability scale. However, for those who dream to go to Mars, at least they can say there is a possibility that it could happen.

What will NOT happen to the people who go on the Mars One Mission?
