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.
Lunar Dust Fighters | Dust yourself off
Develop a LDS to detect, map, and mitigate lunar dust to reduce the effects on astronauts or spacecraft interior systems.
Background:
Blasted by meteor impacts to sizes even smaller than one micron, lunar dust invades and sticks in tiny spaces. Its particles are easily blasted across the lunar surface and to high altitudes by rocket engines. The dust has dielectric properties that cause it to be lifted electro-statically off the surface of the moon to inconvenient locations at inconvenient times.The threat of lunar dust to human health and spacecraft systems is driving future design and operations of those systems to minimize its effects and mitigate it when present. But how can the dust be mitigated unless we know where the dust is located? It may be too small to see, blending in with the background or hiding in crevices. It would be helpful to identify this dust as early as possible, both inside and outside of lunar spacecraft.Your challenge is to create a lunar dust inspection/detection system to help in reducing dust presence and/or addressing the hazard it could cause anywhere from the lunar surface to the free-floating conditions inside the spacecraft after it leaves the lunar surface.
Solution:
LDS (Lunar Dust Detection System) uses infra red sensors on suit seals and robotic arm in side spacecraft to detect amount and location of lunar dust.mapping data to mobile app - approximates the system in spacecraft -to visualize where and when mitigation is needed.for mitigation, vacuuming and magnetic field is used, and app check if still remains.also, using super nano hydrophobic spray on suits before going to missions can reduce lunar dust effects.
