Being a fan on NASA and space exploration in general, its been an honor that my design chosen to represent NASA's radiation shielding in NASA's crowdsourcing project, here is a bit about the project
NASA folding radiation shield being deployed in the cis-lunar space before blasting off to Mars. to protect the habitats in MTV (Mars Transit Vehicle) from Galactic Cosmic Radiation or any kind of debris from damaging the habitat.
The shield needs to be thick enough to be able to sustain GRC, while also maintaining the flexibility and storage efficiency.
The cap end can be removed or even extended allowing the placement of propulsion.
