An Overview of the Instrument Suite for the Deep Impact Mission, crater formation for the Deep Impact mission. The high-resolution instrument (HRI) consists of an ./35 telescope with 10.5mfocal length, and a combined filtered CCD camera and IR spectrometer. The medium-resolution instrument (MRI) consists of an ./17.5 telescope with a 2.1 m focal length feeding a

The History and Dynamics of Comet 9P/Tempel 1,vations for the seven apparitions beginning in 1967 have been fit with an orbit that includes only radial and transverse nongravitational accelerations that model the rocket-like thrusting introduced by the outgassing of the cometary nucleus. The successful nongravitational acceleration model did no

The Coma of Comet 9P/Tempel 1,ucleus as its component icy volatiles sublimate. Driven mainly by water ice sublimation at surface temperatures . > 200 K, this coma is a gravitationally unbound atmosphere in free adiabatic expansion. Near the nucleus (≤10. km), it is in collisional equilibrium, at larger distances (≥10. km) it is

Impact Cratering Theory and Modeling for the Deep Impact Mission: From Mission Planning to Data Anaegard to the impacting energy, target material, space environment, and extremely low-gravity field. Consequently, impact cratering theory and modeling play an important role in this mission, from initial inception to final data analysis. Experimentally derived impact cratering scaling laws provide u

The Deep Impact Earth-Based Campaign, an intensive world-wide observing campaign designed to obtain mission critical information about the target nucleus, including the nucleus size, albedo, rotation rate, rotation state, phase function, and the development of the dust and gas coma. The specific observing schemes used to obtain this in
