Let Knowledge Serve NASA

NASA’s go-to problem solver

Liquids in zero gravity don’t pour, don’t spill and don’t drip. But PSU mechanical and materials engineering professor and former NASA scientist Mark Weislogel found a way to make them behave.

An expert in fluid dynamics, Weislogal has designed numerous experiments performed by astronauts aboard the International Space Station. He and his students used complex mathematics to design a coffee cup that allows liquids to be sipped instead of sucked from a tube. That’s great news for coffee-loving astronauts, and the science behind it has implications for space travel that are out of this world.

At Portland State University, we believe knowledge works best when it serves the community.
