Answer: b. NASA

– Scientists at NASA’s Johnson Space Center have successfully extracted oxygen from simulated lunar soil.
– The lunar soil consists of fine particles that cover the surface of the moon.
– For the first time, oxygen has been extracted from lunar soil in an export environment.
– The amount of oxygen produced is sufficient to fulfill the one-day oxygen needs of space travelers present on the surface of the moon.
– It can also help with the use of other resources available there.
– This is known as In-Situ Resource Utilization.
Research for the Artemis Mission
– NASA is preparing to send space travelers to the moon through its Artemis mission.
– The real purpose of this mission is to establish a long-term presence on the surface of the moon.
– The production of oxygen is the most essential task for this mission.
– Oxygen can be used not only for breathing but also as propellant for transportation.
– This will help space travelers to stay and progress on the moon for a longer duration.
How oxygen was made from lunar soil
– NASA’s Carbothermal Reduction Demonstration (CARD) team created conditions similar to those found on the Moon using a special 15-foot circular chamber called the Dirty Thermal Vacuum Chamber.
– It is called a dirty chamber because it can be used to test impure samples.
– The environment inside the chamber is similar to that of the moon.
– The team used a high-power laser to simulate heat using a solar energy concentrator and melted the lunar soil inside a carbon thermal reactor developed by NASA’s Sierra Space Corporation.
– A carbon thermal reactor is a place where the process of heating and extracting oxygen takes place.
– After this process, scientists were able to obtain oxygen.
