Apollo 13 astronauts participate in walk-through of EVA timeline at KSC

S70-29673 (28 Jan. 1970) --- Astronaut Fred W. Haise Jr., lunar module pilot of the Apollo 13 lunar landing mission, participates in a walk-through of the extravehicular activity timeline at the Kennedy Space Center. Here, Haise uses an Apollo Lunar Surface Drill to dig a three-meter heat flow probe hole. The heat flow experiment on Apollo 13 will have an electronic instrument which will measure the outward flux of heat from the moon?s interior.
