NASA administrator Charles F. Bolden grabbed the public's attention at the Humans 2 Mars Summit laying out a multi-billion dollar plan to get humans on the surface of Mars by 2030.
"If this species is to survive indefinitely, we need to become a multi-planet species," Bolden said.
The public doesn't think that's unlikely. A poll funded by Explore Mars and Boeing showed that 75% believe that people will land on Mars by 2033. Chris Carberry, executive director of Explore Mars, said “The survey results suggest Americans are ready for a renewed dedication to exploring the solar system.”
