A systematic parametric variation for the positive ion collection by a rocket-borne probe has been completed for the following parameters speed ratio 3.10 non-dimensional front face potential -200 zero sidewall potential Debye numbers from 0.01 to 1000 and Knudsen numbers from 0.007 to 1000. The effects of finite space charge on the vehicle are to lower the ion flux to the stagnation point. It is found that the ion flux follows a uniform trend for Knudsen numbers greater than 0.2, but becomes complicated for the near-continuum regime, e.g., Knudsen number equal to 0.007, which is discussed in detail.
