We have devised two ideas, where it manages to minimise or even eliminate the shock and abrupt detachment of pods of rocket. 

Our design consists of a piston contained within an air-filled and tightly sealed container. The vibration caused by the rocket's launch generates air pressure. The piston shaft interlocks with the ring, one end of which is tied to the rope, so that when the air is agitated by the vibrations produced during the launch, it heats up and exerts pressure on the piston, restricting its upward motion. 

When the top lid is opened, the air pressure is released, and the piston moves up and the ring is separated from the shaft of the piston, releasing the pod.

Memory metal can be triggered with very little current, lowering the impulse. We can change the locking with Memory Metal because it changes shape depending on the current. We're using Nitinol, which is a nickel and magnesium alloy. It can be activated with a low current (6-12V) or at a temperature of 70 degrees Celsius. It is also resistant to corrosion and has a high tensile strength. Because we use a low current, Nitinol reverts slowly, reducing the force required to release the pod.

We have attached a small gif and pic as representation to our idea. From this, we hope to achieve to reduce the cost and increase the efficiency of pod detachment with minimal usage and reusable parts.

The direct benefits of exploration include the generation of scientific knowledge, the diffusion of innovation and the creation of markets, the inspiration of people all over the world, and the formation of agreements between countries involved in exploration. 

Rocket science is founded on fundamental scientific concepts such as Newton's Laws of Motion. Rockets are used by NASA to launch satellites and send probes to other planets. The Atlas V, Delta II, Pegasus, and Taurus are among these rockets. NASA also conducts scientific research with smaller "sounding rockets." Instead of flying into orbit, these rockets ascend and descend.

The Space Launch System rocket and the Orion spacecraft are being developed by the agency for human deep space exploration. NASA will create new opportunities in lunar orbit with the help of commercial and international partners, including a platform to aid surface exploration and serve as a gateway to Mars.

Our project is inspired from the "pogo effect"(taken from nasa) in this effect large mangnitude of vibrations are created.

So we thought of using those vibrations as a medium to agitate a gaseous medium inorder to create random motion which could lead into producing a little amount of heat and pressure, on which our whole locking mechanism is designed(metioned in description). The other mechanism which involved memory metal fastener(Nitinol) , this is inspired from the resource provided in the

nasa space app challenge about shape memory alloy based launch lock , the difference is that there they used heat , where in case of our model we are using electricity and nitinol,which changes its shape when a jolt of current is given to it.
