Many scientists believe that humanity has a date with extinction if we do not try to expand our horizons. It took about 4.5 billion years for mankind to evolve into the intelligent beings we see when we look in the mirror. For this very reason scientists believe that mankind would make a grave mistake if we do not put forth a dedicated effort in saving humanity. There are many concerns that are facing mankind in attempting to colonize space and other planets. However the dangers of not colonizing space and other planets outweigh the attempt remarkably. Mankind has proven time and time again that if we come together as one, we can accomplish anything. Some scientists believe that humanity can become extinct if an asteroid was to slam into our planet. Research has proven that a catastrophe of that magnitude has already occurred. Many scientists theorize that this could have been the cause of the extinction of the dinosaurs. Other researchers like Stephen Hawking, believe that humanity will destroy itself. Stephen Hawking is a professor of Mathematics at the University of Cambridge and he is regarded as one of the most brilliant theoretical physicists since Albert Einstein. He says, “In the last two hundred years, population growth has become exponential, that is, the population grows by the same percentage each year” (Hawking ,158). The current rate in which the human population grows each year is about 1.9 percent. That might not sound like much, but at that rate the human population doubles every 40 years. According to Professor Hawking, “By the year 2600 the world’s population will be standing shoulder to shoulder, and electricity use will make the Earth glow red-hot” (Hawking ,158). Professor Hawking believes that the only way that humanity can co-exist in harmony is by colonizing space and even other planets. Out of all the Planets in our Solar System, scientists believe that Mars is the best candidate for humans to colonize. Currently the National Aeronautics and Space Administration (NASA) have two remote controlled rovers that are exploring the Martian terrain. On April 7, 2001 NASA launched a satellite called the Mars Odyssey. This satellite is currently orbiting Mars and taking pictures of the Martian surface. Mars Odyssey is searching for past and present evidence of water and volcanic activity. It also relays communications between the Mars Exploration Rovers (MER) and the Phoenix Lander to Earth. NASA has discovered ice at the polar regions of Mars, which means that the planet sustains water. We all know that water is the key to life, however there has been no discoveries of life on Mars, yet. Researchers believe that we must look to colonizing Mars whether we find life on it or not. As of now NASA is not working on any kind of mission to send humans to Mars. In July of 1989 President George Bush had announced that he wanted NASA to plan a manned mission to Mars. NASA then did their research and three months later they came up with a budget and an approximate time that they would need to prepare for sending humans to Mars. In their 90 day report, NASA stated that they would need $450 billion and 30 years to be able to successfully accomplish such a mission. Congress said no to NASA’s budget to go to Mars, and since then the mission has been on hiatus. Not many people argued with Congress because $450 billion and 30 years is an obscene amount of time and money for any kind of mission. For this reason there have been private organizations trying to come up with ideas to accomplish this mission cheaper and in less time. Mars Society is the leading private organization that is working feverishly to come up with a solution that can get humans to Mars in an affordable and an expedited manner. Mars Society was formed in August, 1998, with about 700 people from every walk of life and from many different countries. Dr. Robert Zubrin the president...
