The SSJ, (Secure Space Jar), is designed specifically to hold rocks and sand in space. It has a circular middle section and an outer section around it, conveniently separating the two substances without any mix-up. It also comes with a snap-on cap that has another top in its middle securing the rocks and sand in the SSJ in both sections. On top of the cap is a circular handle, making it a lot easier taking it on and off. In addition, the SSJ has edges of the body are rounded, making it easier to handle under anti-gravity conditions. These are some of the reasons why this simple looking container could help astronauts with transporting goods from space back down to Earth.
