Brief

Create a sample collection bag that can be easily transported by an astronaut after collecting lunar rock samples, and can be easily stored when not in use.

Concept

A spring loaded lightweight bag that could be transported easily, easily collapsed when not in use, and could stand upright even when empty while in the process of collecting lunar rock samples.

Existing Sample Collection Tools & Processes

Multiple tools are involved in the lunar sample collection process. From contact soil sampling devices to trenching tools, an astronaut is responsible for a carrier holding all of these devices.

The Sample Collection Bag is one of these many items in which an astronaut stows all lunar samples.

The Sample Collection Bag must be able to stand upright on the lunar surface. A rigid structure is imperative so that the bag stands upright even when empty.

The Sample Collection Bag must be easily stored after transferring the lunar samples to the Sample Return Container.

Ideation

We analyzed these sample collection procedures and tools, an astronaut's restricted mobility, the limitations of the suit and gloves, usage versus storage, and shape versus orientation.

While refining our concepts, our main focuses were the bag's rigidity, collapsibility, and ease of use both physically and visually.

Prototype

Our final design proposal was a spring loaded lightweight bag that could be transported easily, providing little arm strain. The circular shape would be more stable than the current rectangular based bags. The spring wire construction would enable the bag to be easily collapsed when not in use, and would enable it to stand upright even when empty while in the process of collecting lunar rock samples.
