In addition to the earth, NASA is trying to find the most effective way to ensure sufficient moisture and ventilation for plants to grow in space. As humans compete for interplanetary competition, one of the most important needs will be food. Although a colony on another planet is likely to appear in the future, first obtained supplies from the earth, but ultimately humans must learn the science of growing food under adverse conditions in an attempt to break through the boundaries of agriculture.
The Space Station (ISS) flew 200 miles from the Earth in a weightless atmosphere. According to NASA, the project is part of an ongoing NASA study that aims to find out how astronauts spend weeks, months or even years in space performing long-term missions to the moon and Mars . One of the main observations made during the project was that it was a challenge to ensure adequate hydration and ventilation of the plant root area under zero gravity.
The project worked with biologists to determine the needs of plants and the challenges of trying to plant vegetation on the International Space Station. There are two main methods to consider when supplying water throughout the life cycle of plants: First, use soil to provide water for plants as on earth, and the second method is innovative hydroponics. With this method, there is no soil and the plants are directly in the water.
Researchers tried to use a long-lived plant to create it artificially and simulate its growth on the International Space Station. Use felt cloth, foam rubber and sponge. Create simulated plants, which include other physical attributes, which can reflect the plant’s root system and evaporation rate. Therefore, the team does not have to agree on the biology of working with real plants. Punches containing nutrients and sugar are used to simulate more soil conditions of plants.
The PWM project completed the first batch of operations of the space station in late February and completed the final iteration in early April. The team has collected valuable data and hopes to conduct more tests in the future.
