The September 1966 JPL Voyager Project Estimate-14 briefing gave a profile of the planned orbital operations of the Voyager spacecraft.

The September 1966 JPL Voyager Project Estimate-14 briefing gave a profile of the planned orbital operations of the Voyager spacecraft. 1-The Voyager craft approaches the point of insertion into orbit of Mars. 2-After orientation of the orbiter (capsule), the lander in its aeroshell (canister) separates from the orbiter. 3-The orbiter and lander continue around the planet, 4, 6, 9-The orbiter is turned to achieve the attitude of communications with Earth. 5-A retrorocket impulse alters the velocity of the lander by 275 meters per second, causing it to deorbit. 7, 8-One to three hours after deorbit, the propulsion unit on the lander canister is released and the canister is oriented for final approach to the Mars surface.
