The experiment, known as Remove Debris, used a one-meter cube satellite built by Surrey Satellite Technology Ltd. and launched by SpaceX to the International Space Station earlier this year. The largest satellite ever deployed from the orbital lab, Remove Debris contained the target satellite seen above, as well as another small satellite it will use to test range-finding sensors. Later, it will also shoot a tethered harpoon at a target that it extends from its body to test a different method of disposal.
