There was once a time when Uncle Sam and NASA opened the wallet to fund space travel and space research.
That was then. This is now.
These days, space scientists have to get much more creative in raising those research dollars.
Case in point: Benjamin Longmier, who's an assistant professor of aerospace engineering at the University of Michigan. His special area is propulsion, as he seeks to build the kind of thruster that will push a spacecraft out of Earth's orbit and send that space craft to other planets.
We spoke to Benjamin Longmier about his research a few months ago, and now he's moving to the "creative fundraising" stage of things.
Benjamin Longmier joined us today.
