CLEAN : Moon and Mars veggies grow in Dutch greenhouse

The video tutorial discusses the challenges of using real lunar and Martian soil for experiments, leading to the use of NASA's substitute soil. The experiment involves planting various species, including potatoes, due to their nutritional value. Conducted indoors, the experiment simulates conditions on Mars and the Moon, where harsh environments prevent outdoor growth.

What was the main challenge in working with real Mars and Moon soil?

• The soil was too heavy to transport.

• It was impossible to obtain.

• It was not suitable for plant growth.

• The soil was too expensive.

How many pots were used in the experiment?

• 1000

• 600

• 840

• 500

Why were potatoes chosen as one of the crops in the experiment?

• They are easy to grow.

• They are featured in a popular movie.

• They require less water.

• They are the most nutritious crop.

What is a major environmental challenge on Mars that affects plant growth?

• High temperatures

• Extreme cold and lack of air

• Excessive rainfall

• Lack of sunlight

How do researchers simulate Earth-like conditions for plant growth in the experiment?

• By using artificial sunlight

• By controlling air pressure and temperature

• By using hydroponics

• By adding fertilizers
