Space agencies like NASA believe that when technology is ready, humans will move to Mars and begin colonization. However, some experts are not just warning about technological complications that people are encountering in their attempt to reach the Red Planet. The biggest hurdles that people have to overcome will be psychological, experts say.
These include the prospect of crews not getting along, interplanetary "jetlag" and the idea of pushing Mars into a spacecraft six months later, and then on the Red Planet in a small dome once.
Dr. Federico Caprotti of the University of Exeter said: "The biggest hurdles to settling Mars are not technical but psychological."
"Long distance missions raises psychological questions that current knowledge in space research can not answer."
"For example, the International Space Station enables a speedy return and a sense of psychological closeness to the Earth.
"Mars allows this and that does not pose the danger of intense pressure."
"There is also the question of interplanetary jet lag. The journey could take about 400 days ̵
"The psychological impact of such a long journey in combination with the lack of real-time communication with Earth as signals could take four to 24 minutes to complete."
Every day, the prospect of living on Mars gains traction, and China, NASA, and private space companies such as SpaceX are striving to do so.
NASA astronaut Buzz Aldrin said he would be settled in Mars by 2040. Tech billionaire Elon Musk is more ambitious and claims to be around 2030 Bringing people to the Red Planet.
Last year, the SpaceX chief said that this could be achieved in about 10 years, "maybe even nine years earlier."
