A Space Probe is a mailable Item used for gaining the Star Justice Badge of Honor or the Space Skull Badge. They are used for clicking on Space Probe Mission Modules, where, upon clicking, the clicker spends a Space Probe for a chance to win Bob Skull's Coordinates. It costs 1 Space Fuel Cell to set up a Space Probe Mission Module. Alternatively, if a user spends this on an Interstellar Ambush Module, the owner of the Module gets a Lost Space Probe.
