Apollo 16 (Orion)

  1972-031C

---

Lunar Module 11 `Orion' was the second J-class LM to fly, on the Apollo 16 mission to the Descartes Highlands. Crew of Orion were Capt. John Young, USN and Lt-Col Charles Duke, USAF.

Orion landed at Cayley-Descartes, 8.99S 15.51E.

Duke: `Contact. Stop. PRO. ENGINE ARM. Wow - wild, man! Look at that!' Young: `Pro. Engine Arm. Descent Engine Command Override. Okay, 413'. Duke: `Check the APS'. Young: `Well, we don't have to walk far to pick up rocks, Houston. We're down among them'.

After a sleep period, Young began the mission's first moonwalk. `There you are - mysterious and unknown Descartes Highland Plains. Apollo 16 is going to change your image. I'm sure glad they got ol' Brer Rabbit, here, back in the briar patch where he belongs'.
