One of the big problems with space travel is that one cannot over pack.
Suppose astronauts reach Mars. How do they explore the planet if they cannot weigh down the vessel with fuel for excursions?
A team of undergraduate aerospace engineering students at the University of Michigan is doing research to help astronauts make fuel once they get to Mars, and the results could bring scientists one step closer to manned or extended rover trips to the planet.
