mission and study science, technology and medicine.
Mars One is
also going to
send a rover in 2018
to test some of the
technology the astronauts will use. Then, in 2020,
another rover will land on Mars. Its job is to find a good
place for the humans to build their village. In 2022. six
spacecraft will travel to Mars carrying everything the
astronauts will need to live on Mars, including a
machine to produce water and make the air safe to
breathe. Two years later, the astronauts will land and
their adventure will begin!
