Explosive formation

Moon dust is formed mainly

by grinding and explosions,

caused by meteors. The

impact breaks the rocky

surface into pieces.

Plants in lunar soil

Moon dust contains many of the

nutrients in soil. Scientists have

even been able to grow plants in

soil that mimics Moon dust. The

plants grew for up to 50 days.

Studying lunar soil

People last went to the Moon

on the Apollo missions of the

1960s and 1970s. Astronauts

collected Moon dust to study

back on Earth.

The Moon is

constantly

bombarded

with meteors.

Meteor impacts cause

bits of Moon rock to

fly into space.

Astronauts drilled

into the ground to

collect samples.
