Space travel has long been on the minds of the human race. In 1835 the Great Moon Hoax brought us the modern fever of wondering if there is life out in the stars. The Sun, a New York newspaper, reported fake stories about fantastical lifeforms found on the moon observed through earth bound telescopes. Since then of course, we’ve traveled to the moon and back and realized there are no trees, oceans, or anything near what we can call evidence of intelligent life out on the moon. Our attention seemed from that point to quickly swerve to travel to other planets, particularly Mars.
Mars has become Earth’s “backup plan”. Similar in size and with suitable gravity, we’ve seen it as a place that we will one day inhabit—maybe in the event that Earth is beyond saving. Getting there has never been more of reachable goal than it is today; technical readiness, public interest, and political will are finally all aligned to get human beings there. Both NASA and SpaceX have invested interests in getting us to the Red Planet in the next 20 years.
How will humans fare on this new planet however? Mars, while similar in size to Earth, is a much more unforgiving environment. No plants grow in its dry soil, there is no liquid water, and we cannot breathe much needed oxygen in its environment. Our lives on Mars would be limited to being indoors, or in complex space suites whenever we get the chance to step foot outside. We’d battle the fatigue of being constantly being cooped up and surrounded by others. We’ll need to provide shelter to these pilgrims; create ways to grow our own food and provide the inhabitants with clean water. Additionally, astronauts going to Mars will need protection from the extremely high levels of radiation out on the surface of the Red Planet.
In the face of all this, we as humans continue to press forward. Truly the spirit of explorations is shown at its best in these efforts. While only time will tell what will become of our attempts to colonize Mars, we know that the idea of space travel will always light up our minds with wonder and excitement.
