Did Obama sign an executive order? Or is this a motivational announcement?
As a contrast, in my field (computational science) Obama signed an executive order (https://www.whitehouse.gov/the-press-office/2015/07/29/execu...) to enable the rapid development of exascale (next generation) supercomputers.
Funding is arguably even more critical for space exploration, and without substantial action on this front I am skeptical this is going to have meaningful impact.
