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.
