Summary Discussion on Re-entry and Planetary Entry—Physics and Technologyay-load (personnel, instruments, and so on) on the Earth surface or planetary surface. For atmospheric planets, the problem involves essentially deceleration, aerodynamic heating and control of the time and location of landing. For non-atmospheric planets, the problem essentially involves only decel

Orbital and Celestial Mechanicsore entry into a planetary atmosphere. When a vehicle approaches a planet in the absence of air, its orbital trajectory may be in the form of an ellipse when its speed is less than .*, a parabola when its speed is equal to ., or a hyperbola when its speed is greater than ., the basic equations** are

Entry Radiation—Magnetogasdynamicstemperature and rather low density of the atmosphere. Under such conditions, the gas will be ionized and the thermal radiation is not negligible in the flow field. A complete analysis of such high temperature flow fields should be based upon a study of gas dynamic field, electromagnetic field and ra
