Is life possible
on Mars?
Pictures from space show that Mars
is a cold, dry, and rocky planet.
Scientists at NASA want to discover
if life is or was possible on Mars.
They’re
searching for water and
signs of life. But they aren’t sending
astronauts to Mars. They’re using
robots.
The
Curiosity rover landed on Mars
on August 6, 2012. It’s
a robotic
laboratory. The rover has seventeen
special cameras and lots of other
tools. It explores Mars,
and it collects
rock and soil samples. It can break
rocks with a laser, and it collects
samples with a special arm. Then
it
uses computers to study the
samples, and it sends information
back to Earth.
From this information, scientists
know there was once water on Mars.
Do you
think the rover is going to
fi nd
signs of life?
