Space agencies and scientists have been studying Mars for many decades. Rovers that are sent to the Red Planet have provided evidence which stated that the planet could someday host life. Establishing human colonies on Mars could take several decades, but scientists have found that the planet contain methane, which is the main component of natural gas.

According to Untied States space agency the National Aeronautics and Space Administration (NASA), there could be fruitful human missions to the Red Planet soon as Techshot a research and development firm in Indiana, is going to help the agency with the effort to produce oxygen on the Red Planet. As per the space agency, if the plans succeed, future missions to the planet will be able to proceed without oxygen tanks.

Scientists said that oxygen and nitrogen on the planet will be generated by oldest of all living organisms, which are bacteria and algae. According to the scientists, to successfully land human missions and establish life on Mars, it is very important to generate essential environment on the planet. The one necessity to land on Mars is ‘self-sufficiency’, they added.

While talking about the presence of Methane on Mars, NASA scientist Kevin Zahnle said that he is convinced that the planet has methane. But, according to him, it has to be coming from the rover.

Chris Webster, a member of the NASA’s Curiosity rover team, said that the team has been continuously watching the amount of methane and they did not notice any leakage from the rover during the entire mission. Webster said, “While it’s true that the concentration of methane in that chamber is 1,000 times higher than in Mars’s atmosphere, the comparison is actually misleading. You have to look at the amount of methane, not the concentration”.
