As NASA and private companies inch closer to establishing a colony on Mars, the challenge of securing a sustainable oxygen supply remains a formidable obstacle. However, a group of researchers has discovered a potential solution involving a specific type of bacteria that thrives in extreme environments on Earth. This discovery could pave the way for producing oxygen on the Martian surface, opening new possibilities for future colonists.
The Oxygen Challenge on Mars
Creating a self-sustaining colony on Mars comes with numerous hurdles, one of which is the scarcity of oxygen in the Martian atmosphere. Overcoming this challenge is crucial for ensuring the survival and well-being of future Mars residents.
The Role of Chroococcidiopsis Cubana
The research team proposed a groundbreaking approach by harnessing the capabilities of a bacterium known as Chroococcidiopsis Cubana. This remarkable bacterium has the ability to consume carbon dioxide (CO2) and produce oxygen. By employing plants coated with this bacterium, scientists aim to generate a sustainable oxygen source on Mars.
Creating the Biocoating
To make this idea a reality, the team developed a biocoating that fulfills the requirements for the bacterium to thrive on the Martian surface. This coating needed to be robust and porous to facilitate the movement of cells within the bacterium. The researchers meticulously monitored the biocoating’s performance over a 30-day period and observed consistent oxygen production. For each 35 ounces of this unique paint, it could generate 400 grams of oxygen per day.
The Green Living Plant
The invention, aptly named the “Green Living Plant,” has the potential to revolutionize oxygen production on Mars. However, to be viable in the Martian environment, it must be capable of producing 500 metric tons of oxygen annually.
