Nasa Admits Humanity Will Not Survive Unless We Get To Mars

Nasa has admitted that humanity will not survive for very long unless we make it to Mars.

Nasa administrator Charles Bolden said that humans have to become a "multi-planet species" within a couple of centuries to avoid certain disaster.

Bolden was speaking at the Humans 2 Mars Summit on its - currently hypothetical - plans to put a manned spacecraft on Mars by 2030.

He said:

"One reason we need to go to Mars is so that we can learn a little bit about living on other planets ... Mars is a steppingstone in the steppingstone approach to other solar systems and other galaxies and things that people have always dreamed of but frequently don't talk about."

Take a look at the rest of the speech in the video above.

Meanwhile there are problems on Earth Nasa should also maybe take a swing at - like perhaps the imminent destruction of all life by surprisingly regular asteroid impacts.
