Fluids behave very differently in space. We can make good use of it. For example, a recent NIAC grant was awarded to investigate a Magnetohydrodynamic Drive for Hydrogen and Oxygen Production in Mars Transfer. This is a system that should provide breathing oxygen for a journey to Mars made out of water with no moving parts in it. 🟣 Guest: Dr Alvaro Romero-Calvo https://ae.gatech.edu/directory/person/alvaro-romero-calvo 👉 More about the NIAC project: https://www.nasa.gov/general/magnetohydrodyn...
