Moon dust is dielectric in nature & is adhesive to almost every material that it comes in contact with. This creates problem for astronauts & their spacecrafts as clogging takes place. To overcome this problem we researched the topic thoroughly & came up with a mechanism that will minimize the dust content on the surface of spacecraft.
Biggest challenge was to tackle the high stream of lunar dust in the orbiters' path. Also the hatch & astronaut suit was taken into consideration for minimizing the damage. This led us to whole new research of moon, its surface properties & effect of other exotic body on it.
