NASA's Hubble Space Telescope took this close-up of the red planet Mars in 2007, when it was just 55 million miles away.
For the past few months applicants around the world have been applying to be some of the first people to head to Mars for a one-way mission. A privately-run non profit called Mars One has launched a competition to find the four candidates that they hope to send to Mars by 2022.
So far, more than 80,000 people have paid between $5 to $75 to apply.
Erica Meszaros is one of them. She joins the show to explain why she'd want to be among the first to go to Mars, even though she wouldn't be able to come back.
