The impactor strikes the ground, throwing up debris.
The impactor mass for the onset of the atmosphere and vapor cloud loss is assumed to be midep, under which the equality in the inequality (16) holds with the impactor-vapor mass relation (19) and the velocity-energy relation (20).
The impactor is assumed to be a metal sphere and the contact process between the impactor and the laminated plate is described by a modified Hertz model.
The impactor performed well without coating material by using just the cooling impaction plate.
The impactor was calibrated at four different configurations with monodisperse dioctyl sebacate (DOS) aerosol.
The Impactor section of the spacecraft contains an instrument that is optically identical to the MRI, called the Impactor Targeting Sensor (ITS), but without the filter wheel.
The impactor returned images as late as three seconds before impact.
The impactor spacecraft executed three correction maneuvers in the final two hours before impact.
The impactor was maneuvered to plant itself in front of the comet, so that Tempel 1 would collide with it.
The impactor position of ELSD was set off.
The impactor sample was collected directly from the breathing zone of the nose-only exposure system.
