For my 8th grade honors science class we are currently doing astronomy. We got assigned a project where we have to create a landing module like the module that people land back on earth in. The catch is that it has to be able to fit in a 10cm x10cm x10cm box and be able to fit a large sized egg so the hatch has to be approx. 5.8cm x4.3cm. The drop height will be about 3 meters and has to land upright on the concrete floor so that the hatch can be reopened to remove the egg to check for cracks and whatnot. It also has to have like handles or something so that it can be held. The module itself cant have any glass, liquid padding, or any food like peanut butter. We are also able to use small parachutes.
The Attempt at a Solution
I was thinking of like a Pyramid type module so that when it is released at approx. the air will be pushing back on the large bottom when dropped making a natural airbrake. What is your guys' opinion?
