If the chemical reactive particles are deposited in the lungs, they may cause respiratory disease. Long-term exposure to the dust may cause a more serious respiratory disease similar to silicosis. During lunar exploration the astronauts’ spacesuits will become contaminated with lunar dust.

What does the Moon look like during the waning crescent phase?

During this phase, the moon is usually positioned at the third-quarter position, meaning it has orbited about three-quarters around the Earth. The waning crescent phase is characterized by a crescent-shaped moon that reduces in size each day until it becomes invisible.
