Female teenager could be the first person to set foot on Mars

A space-obsessed teenager from Hammond, Louisiana, USA, may become the first human to set foot on Mars.

Alyssa Carson, 17, is currently training to become an astronaut and could be the perfect age when NASA's first manned mission to Mars takes place in 2033.

Although she can't apply for NASA's astronaut training program until she turns 18, Alyssa has already completed the NASA Passport program by visiting all the NASA Visitor Centers in the US.

As the youngest person to graduate from the so-called "space prep" Advanced Possum Academy, Alyssa is technically certified to go into space.
