Thruster grid clear circuits and methods to clear thruster grids (206, 208) are disclosed. An example apparatus includes a low voltage grid clear circuit (212) to apply first energy to a grid at a first voltage, and a high voltage grid clear (214) circuit to detect a failure of the applied energy to clear a short circuit condition of the grid and to apply second energy to the grid at a second voltage higher than the first voltage.
