A review is given of the reasons for the interest in active shielding and the types of missions for which an active shield would be particularlydesirable are discussed. Recent work on active shielding is reviewed. Electrostatic shielding is discussed. In general, the maintenanceof an electrostatic field for shielding purposes will require the expenditure of power owing to the presence of a neutral highly conducting plasma. Estimates of the power required are extremely high, and electrostatic shielding appears unattractive.
