Astronauts Could Rely on Algae as the Perfect Life Support Partner

From the Soyuz capsule, Space Shuttle Endeavour during Expedition 27 is docked to the International Space Station 220 miles above the Earth. Before Apollo 11 landed on the Moon, plans were underway to develop the next generation spacecraft that would lower the cost of human spaceflight and make trips routine. Forty years have passed since the Saturn rocket last flew and four years since the last Shuttle. Supporters on Capital Hill appear resigned to accept a replacement for the Shuttle, while inhernently safer, will cost $600 million per launch excluding the cost of the payload.

When planning for long-duration crewed missions, one of the most important things is to make sure that the crews have enough of the bare essentials to last. This is no easy task, since a crewed spacecraft will be a crew’s entire world for months on end. That means that a sufficient amount of food, water and oxygen will need to be brought along.

According to a new investigation being conducted aboard the International Space Station, a possible solution could lie with a hybrid life support system (LSS). In such a system, which could be used aboard spacecraft and space stations in the near future, microalgae would be used to clean the air and water, and possibly even manufacture food for the crew.
