The Challenge | Design by Nature

Design an autonomous free-flyer to inspect a spacecraft for damage from Micro-Meteoroid and Orbital Debris (MMOD).


Easy to detect Faster to solve

  • Micro-Meteoroid and Orbital Debris(MMOD) have significant threat to space exploration
  • Average impact speeds for orbital debris on spacecraft: 10 km/s, and 20 km/s for micro meteoroids international Space Station
  • Although the ISS uses Whipple shielding to protect itself from minor debris, portions (notably its solar panels) cannot be protected easily

Fleacho Grid system

Presentation :

•Figure 1:

Space is no longer what it was in the old days. Dense clouds of bad tempered bullets, which we call space debris, occupy what once was a place full of harmless vacuum. It seems better to adapt to this new scenario, as (almost) nobody would like to see how the International Space Station suffers an unnoticed damage, or an astronaut receives an impact from the rests of Apollo 13.

So, our solution we inspired from the nature in main . The pure concept to create a net covering the hole body of station area , by dividing the big area to small areas which we can control it easily but,in the same time we controlling all of the small integrated areas with the same concept as Grid . The Flea is our nature machinery element and it works with the piezoelectric sensor creating sound waves and this waves can detect the damage area on the hour giving the cabin crew the graph and coordinators to locate where exactly the damage occurred. as we believe easy to detect faster to solve .
