Tue, 30 Jul 2024 - 24min - 1690 - [Interview] Fluids Get Really Weird In Space. NIAC 2024
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.

Tue, 16 Jul 2024 - 20min - 1682 - [Interview] Observing Black Holes With Just One Telescope
Previously the only way to image black holes was with the Event Horizon Telescope, a combination of many radio telescopes across the globe. It is complicated and time-consuming. But with Vera Rubin going online soon, there might be a simpler way to observe black holes with a single telescope using a really clever method.
