OSCAR Overview: What? Orbital Syngas Commodity Augmentation Reactor. Why? Current methods of space waste management are comprehensively unsustainable • Convert trash and human waste into useful gases, enabling long duration human exploration of deep space. Confirm the operability of a space waste conversion reactor in microgravity How? Incineration and steam reforming. Reactor heats (600 °C) the trash under pressure (40 psia) to incinerate it. Suborbital flight sequence trash conversion: 60-70%. Long duration trash conversion: up to 90%.

Investigating Waste Preparation Methods for Trash-to-Gas Technologies

Trash-to-Gas technologies show promise in addressing the need for a proper waste management system onboard a long-duration space mission. However, there is a clear need to better understand how the initial waste preparation can affect the overall conversion efficiency. Factors such as the waste size, moisture content, and packing density can have significant impacts on the reactor performance. This paper will focus on the effects of various pre-processing steps on the overall solid-to-gas conversion on the state of the art Trash-to-Gas system developed at NASA Kennedy Space Center. These results will help inform future Trash-to-Gas technologies on what types of supporting subsystems will be necessary to operate effectively for exploration missions.
