Electrostatically Enhanced Microbe Collection in the Troposphere and Stratosphere

The biggest challenge in aerobiology is the collection efficiency due to the microbe concentration in the atmosphere. The limited access to air samples has prevented systematic studies and some of the basic questions in the field of aerobiology remains open. The project goal was to develop a prototype system to demonstrate electrostatic precipitation for air microbe sampling.

Dust Mitigation: Impacts & Opportunities for Science on the Lunar South Pole

Lunar dust will be a feature of all lunar surface science investigations, whether welcome or not. While lunar dust may pose problems for some investigations, it is also the subject of many critical scientific discoveries made since the Apollo days. Dust mitigation, or learning how to work with and around the inevitable dust we will encounter on the surface, is not a new concept. However, new initiatives throughout NASA are underway in an effort to tackle dust mitigation strategically for the Artemis program. Dust mitigation efforts and technologies will enable successful lunar surface science investigations.
