The Challenge | Dust Yourself Off

The Apollo missions showed us that lunar dust not only clung to everything and was impossible to fully remove, but it was also dangerous to humans and damaging to spacecraft systems. Your challenge is to develop a way to detect, map, and mitigate lunar dust to reduce the effects on astronauts or spacecraft interior systems.

AeroDust Shield

AeroDust Shield is a lunar dust protection system. It uses silica aerogel and electrostatic fields to create a shield based protection core. Protecting all critical mission equipment, minimizing the risk to life posed by inhalation and ingestion of dust.

Overview

All astronauts who walked on the Moon reported difficulties with lunar dust. These problems were likely worsened by the fact that the dust was electrically charged, which enhanced its adhesive properties. Here, we try to decrease the effect of lunar dust properties and its impact on astronauts with a pieces of hardware and software, together with a discussion of the three main problem areas: (1) Dust Adhesion and Abrasion, (2) Surface Electric Fields, (3) Dust Transport.

Goals

  1. Protect all critical mission equipment, including solar panels, instrumentation and camera ports, optical mirrors, and robotic arms, against dust accumulations.
  2. Minimize the risk to life posed by inhalation and ingestion of toxic dusts that may contaminate air and water inside the crew cabin.
  3. Reduce the contamination of extravehicular activity (EVA) suits that will otherwise become covered and severely hindered or inoperable from the constant exposure to lunar debris.
  4. Explore Aerogel properties to develop easier ways of detecting lunar dust.

Specifications

Our electrostatic repeller uses high current to produce an electromagnetic field that is concentrated in ionizing everyday dust particle, making them positively charged (stealing electrons from it), after that we created one thing called a Faraday Cage, were electrons get trapped in one place so it does not interfere with the sensors readings. Using the Coulomb’s inverse square law, we forced every positively charged particle to be now in contact of a positive electrostatic force, and in an abruptly manner it shoot the particles away. We use open data centers to research the properties of the lunar regolith and how it behaves in electromagnetic fields. With the lunar source book, indicated by moderator John Rollings, we come to the conclusion that not all lunar regolith is positively charged, considering that some of them are not able to absorb sufficient gamma radiation from the sun because of its chemical composition, and that these exceptions are a real threat considering the regolith properties of adhesion. To resolve this problem we reached the conclusion of using aerogel polymers to stop the uncharged lunar debris. Silica Aerogel polymers does not react with the lunar dust and are a very light material which bonds properties of great help in covering external material, like high thermal insulation value, (0,005W/mK), high specific surface area (500-1200 m²/g) and high porosity (80 - 99.8%).

Our future plans

In the future we plan to explore more physical properties of aerogel, along with improving the structural portability of our systems.
