description abstract	Abstract: Immediately after the launch of Viking I, large and unexpected non-gravitational accelerations were detected and attributed to outgassing from porous materials (e.g., parachute, blankets, etc.) in the lander. A midcourse correction made to preclude large targeting errors upon Mars Encounter. Every spacecraft design should be reviewed for its potential for outgassing (and its impact on the navigation strategy and the spacecraft) throughout flight.
