It is different from other ISS experiments because for the first time, the work will be conducted outside the station. This was made possible by the Japanese Aerospace Exploration Agency, which built a laboratory module known as Kibo, the Japanese word for hope, with an attached exterior platform where science experiments can be deployed and conducted in open space. Astronaut Dave Wolf explains how the platform enhances the ISS’s capabilities: “It’s a large external porch to the space stastratosphere tion where high quality experiments can be The part of the earth’s conducted in the high vacuum of space.

During its orbit IBEX continuously spins, which enables it to collect particles from every part of the sky. As these are gathered, the sensors and spacecraft keep track of where the particles came 36 from, the time they entered the sensors, their mass, and the amount of energy each particle has.
