My idea for the Mars Medical Challenge was a solid sliding door box that can contain gasses on board the ship, that may be harmful. In space the gas is cooled down so the atoms in the gas would not have as much energy, which would cause them to slow down and move closer together. So if a gas got opened on the ship it would move very slowly and for the most part stay in one area. However, the gas would still move and spread around the ship and if it is a harmful gas it could put the Astronauts in danger That is where the Mars Space Box or MSB comes in. The MSB is a lightweight box with a easy open sliding door, which allows the user to quickly store items in the box. The box is made out of aluminum, and the user can use the box to catch gasses and store them safely.
