Lunar dust feels like fine snow, is strangely abrasive, and smells like burnt gun powder when exposed to oxygen.
It was a minor annoyance during the Apollo missions, which lasted a maximum of three days. Now that NASA is planning to send astronauts back to the moon to stay in the Artemis program, the space agency is looking for ways to control lunar dust so it doesn’t clog up spacesuits, spacecraft and habitats.
NASA has selected nine proposals that address with lunar dust for funding under its Small Business Innovation Research program. The phase I contracts are worth up to $125,000 for a maximum of six months.
The proposals covered a range of technologies. Blazetech Corporation of Woburn, Mass., will develop “an advanced self-cleaning staged dust filter for spacecraft air purification in cabin and airlock chambers.”
Pittsburgh-based Astrobotic Technology has teamed with WiBotic to develop wireless transmission for power systems whose mechanical connections would be prone to getting clogged with lunar dust.
WattGlass of Fayetteville, Ark., will work on coatings for solar panels designed to mitigate lunar and Martian dust.
NASA also selected a proposal from Off Planet Research of Lacey, Wash., that will begin development of self-cleaning, dust-proof fluid and gas connectors.
