The Space Foundation, a global, nonprofit organization leader in space awareness activities, educational programs and major space industry events decided on April 6 to include Dr Marc A. Anderson in the Space Technology Hall of Fame®. The Space Foundation's Space Technology Hall of Fame was established thirty years ago to increase public awareness of the benefits that result from space exploration programs and to encourage further innovation. One of the two selected technologies in 2017 was the Radiant Catalytic Ionization (RCI), a high tech process able to produce hydroxyls through photocatalytic oxidation technology based on the studies performed by Dr. Marc Anderson´s research group.
About Active Pure Radiant Catalytic Ionization (RCI) Technology
In the mid-1990s, scientists at a NASA Research Partnership Center in Wisconsin were working on improving methods of growing plants in space. The problem was the build-up of ethylene gas around plants grown in the closed environment of spacecraft, which caused premature plant decay and spoilage. To combat this, the group developed an 'ethylene scrubber' based on a concept by Dr. Marc Anderson using the existing principle of photocatalytic oxidation where UV lighting and titanium dioxide are used to break down organic compounds like ethylene. The first device was successfully operated on Space Shuttle Columbia in 1995, proving the system could work in helping to grow plants in the space environment. After some refinements, the plant growth chambers for space flight were developed. The ethylene scrubbers that were conceived and developed for this project are the basis for the Aerus’ air purifiers in use today.
