NASA is launching an unmanned mission into outer space, and you can help choose a name for the fake astronaut. The Artemis I test will have a mannequin on board (or "moonikin" as they have called it).
The bracket style voting system has narrowed it down to the final four possibilities: Ace, Delos, Campos, or Rigel. Each moniker has a special meaning that you can read about here. The name will be revealed on June 29th.
