High-Level Project Summary
I develop a mechanism for object separation in space under the challenge of Let it go. It has a simple mechanism and simple equipment. I think, develop a method for this challenge. This mechanism is important for simply satellite separation systems. we can expand this idea for CubeSats separation systems. For smooth separation, I implement a fully sealed fluid chamber to control its acceleration to the spring system. So, we can guide the object to the trajectory with a small acceleration or constant velocity. (This time the acceleration stopped and only the spring system guiding the satellite to the trajectory.)

Detailed Project Description
It has simple mechanical components. Mainly, a Stepper motor, springs, two curved handles. So, the mechanism is, the stepper motor rotates one direction, the satellite rod is release and the stepper motor rotates opposite ward, the satellite rod is getting tight. After release, the spring system pushes the satellite rod to the trajectory. This can be used for normal satellite separations. After Appling a fully sealed fluid chamber to the spring system we can get a smoothly pushing system and guide. (Why guiding? – Because, sometimes space trash attacks the rocket stage. That reason Couse to be damage on our satellite. Because at other times that objects (satellite and rocket stage) in nearly.) The fluid system works like a shock absorber. The spring push into forwarding and the fluid maintain a force backward. In This mechanism, we can get small acceleration or finally, constant velocity. It is reducing our failing probability. Also, we should strengthen our fluid chamber.

For more smooth,
For small satellites, we can use one system of this model, and for large satellites, we should use a minimum of 4 systems like this. Because force equilibrium, when there is turbulence (Ex- Torque). In this separation mechanism, we use rods to connect the payload to the stage. So, we can increase stabilization in a torque state. carefully that time we set our mechanical handles facing to corner direction because it is the best way to decrease the failure probability.
like this,
we can use a satellite base like this,
Space Agency Data
I use NASA open data to build my separation model. I got some ideas and I applied them to my model. I refer to available separation mechanisms failed models to get some ideas. Like, need a spring system to push our object, and so many things. I implement some of them in my project.
these are, some of the examples I used,
Hackathon Journey
This is my first time with the NASA space apps challenge and it is most important in my life. I do with my challenge, I did research about the satellite separation systems and I got many resources like NASA’s data. I improve my knowledge about separation systems. I chose this challenge because I’m an Engineering student. I thank local space apps mentors and everyone helped me.
I could face some challenges in working with software and tools.
