“Hey, Apollo – Houston, this is Apollo 10. Look, I know you ran some studies, but by golly, we can see Snoopy, and he isn’t too far away! He’s catching up with us. Can you talk to the FIDOS? He’s right down below us. We can occasionally see him tumbling end-over-end down below there, and he’s coming in closer each pass. That’s Snoopy’s descent stage. We can see him right down below us now, and he’s right – I thought he was a little out-of-plane, but now he’s looking more in-plane with us.” Tom Stafford Apollo 10

The six-minute retrograde maneuver seemed interminable, just as it had to Borman’s crew on Apollo 8, but the engine kept firing and the Apollo 10 crew’s confidence in it kept growing. When the engine finally shut down and they were sure that it had done its job, Stafford and Cernan had time to look at the lunar surface. They likened one area to a volcanic site in Arizona. Shortly, Stafford forced his attention back inside the cabin and told his crew-mates that he thought the best thing to say when they got back in radio contact with mission control was, “Houston, tell the earth we have arrived.”
