A New Frontier to Our Red Neighbor

Being one of Earth’s closest neighbors and named after a Roman God of War, Mars is the 4th planet of the solar system. It has been an object of wonder for centuries due to being visible to the naked eye. Because of this, Mars has always been a popular choice for our new home. This has been considered more seriously in the recent years due to the rapid increase of human population and the depletion of resources on Earth.

Mars One

Mars One is an organization founded in 2011 whose goal is to establish a permanent human settlement on Mars. With many PhD researchers and large suppliers like Lockheed Martin on board, Mars One planned multiple manned and unmanned missions over the span on 20 years. They plan to start Astronaut training by 2018 for prolonged stay in remote locations, repairing rovers, medical treatment, and food growth. Aiming to launch the first crew in 2031 via the Mars Transit Vehicle, many unmanned missions will be launched before that to experiment with crucial tasks such as water extraction and solar panels, satellite deployment, and setting up an outpost. After the landing, astronauts will set up solar panels and prepare for a second group of astronauts launching in 2033. Mars One has addressed potential risks of this project such as the lives of astronauts and the potential of over budget, however they plan on reducing cost by using existing technologies.

Another plan was drafted recently by a group of scientists and researchers in EPFL, a Switzerland University. The plan was accepted on June of 2018 to set up Martian bases on the polar ice cap regions of Mars. The poles prove to be ideal places to set up a base because it provides a source of water and various elements to create materials. Like the Mars One, EPFL plan to send multiple unmanned missions to construct a habitable base. The design of the base consists of a central core which will act as a living quarter for the astronauts, 3 surrounding capsules will have airlock functionality to minimize pressure change, and a large dome to protect the area within from radiation and the harsh dust storms of the Martian surface. They plan on sending a crew of 6 astronauts to land during the polar summer to maximize sunlight during their stay. The astronauts are planned to stay for 9 months to set up power reactors and a second mission will be initiated to bring cranes for material transportation. A potential issue with this plan is that there is currently no rocket strong enough to carry the planned heavy load.

The Future of Mars Colonization

As human population increase, so does the rate of consumption and the need for us to find a new home becomes increasingly real. With the many advantages that Mars provide and garnering the interest of groups like Mars One and the scientists of EPFL, the Red Planet is a likely option for us to call home in the near future.

Our Potential Future Home, the Moon

Have you ever hiked to the top of a mountain and was rewarded to a beautiful view of nature? One of the first thoughts I got from this view is how vast Earth is. It houses millions of different species with each one falling within a phylum with unique and defining traits. However with the rapid expansion of human society, depletion of resources and the human nature to conquer the unknown, it is only natural for us to worry about potentially searching for a new home. One of the most common places people have looked to colonize is our closest neighbor, the moon.

Advantages of Moon Colonization

Having influenced many science fiction works such as 2001: A Space Odyssey, the moon is the closest celestial body to Earth and it offers some of the greatest advantages for colonization. Not only does this mean a shorter travel time, it also means less spending of resources on transportation as well as more responsive drone control from Earth and quicker communication with Earth. Spacecrafts like the SELENE and NASA’s Clementine Orbiter discovered many areas near the poles where it stays mostly illuminated which means those areas are great for setting up solar panels. On the opposite end of the spectrum, there is also areas of permanent shadow regions discovered by the Lunar Reconnaissance Orbiter. Many of of these areas are craters with water source trapped in them, which can be harnessed and be used by colonists.

Drawbacks of Colonizing the Moon and the Limitations of our Technology

However, even with all of these advantages, there are still many drawbacks to choosing the moon as our next home. The moon has a surface boundary exosphere, meaning that it offers no atmospheric protection from asteroids and radiation, making colonization very dangerous without proper protection. Another issue is the extremely low gravity of the moon, which negatively impacts the human body by decreasing bone mas when the body is under low gravity for extended period of time. Due to this issue, proper habitation modules must be constructed. Not only does it need to shield us from the external dangers such as radiation and asteroids, it also needs to accommodate many internal factors such as, health management, life support, environmental management, etc. This can be extremely expensive and difficult to construct.

How Likely is it to Colonize the Moon?

Interplanetary colonization is a fascinating topic and will definitely be an obstacle humanity will have to overcome in the future. However I believe it is something that we can achieve in the near future. According to NASA’s Alexandra Hall and NextGen Space‘s Charles Miller, we can send another group of people to the moon and set up a colony in 3-5 years from now. The moon is currently our closest option, it offers many advantages as well as many disadvantages.
