High-Level Project Summary
NASA and the other space agencies does not recommend the use of pyrotechnic bolts and separators, it needs special requirements and keeps space junk, our solution is to design and construct a prototype, a mechanical separation device which helps minimizing space junk and protect from the hazardous consequences of pyrotechnic devices, furthermore our prototype is much smaller and capable in term of size, hardness and pressure sensitivity than the existing SMA based separators. Additionally and for the first time, our design is equipped with an extra safety technique applied to components in atmospheric region for example in case of using it in rocket launch in case of electrical failure

Detailed Project Description
We have done several researches involving similar devices used by space agencies specially NASA by the provided huge database, we use to design and develop four test prototypes (our two ways separation device, aluminium separation device , metal cutter and multistage separation device), our basic prototype was constructed based on our test apparatus as well as conducting several experiments to ensure the satisfaction of NASA criteria, we places a lot of effort to make our separation device uniquely and unrivaled, which is present in our safety way of functioning. As you know, rockets used for launching space components are highly expensive in efforts and funds regardless of the carried loads which include satellites and most importantly persons. Our concept preserve maximum degree of safety and relies on the kind of metals that provide durability withstand different serious circumstances
our design is equipped with an extra safety technique applied to components in atmospheric region for example in case of using it in rocket launch in case of electrical separation failure, the device is equipped with pneumatic second way of separation to ensure safe launch.

Hackathon Journey
Space apps experience was so vigorous and robust. It benefit me a lot concerning knowledge and experience, we gained a lot of awareness regarding space, spacecrafts, and the techniques and devices used. For us as innovator who won several award all around the globe, we find the the challenge so beneficial and provided us with the understanding of new concepts and mechanisms in space. Our entrance was inspired by a deep passion to science and plain, as well as to an affection to work on projects in workshops. Our journey was facilitated by our local team leaded by Antoine Tannous and his staff.
