Newt Gingrich made a major speech on space on January 25, which stressed the importance of commercial activities including the use of prizes. He called for a bold and aggressive space program, which by 2020 would establish a permanent base on the Moon, a next generation propulsion system for use in getting humans to Mars, and bustling commercial activities in low Earth orbit. A video of his speech is available from C-SPAN here (NSS will be posting a transcript here late today). The National Space Society looks forward to learning in a similarly detailed fashion the space views of the other presidential candidates.
