Astronauts Lovell and Haise during simulation of lunar traverse at Hawaii
Astronauts James A. Lovell Jr. (left) and Fred W. Haise Jr., Apollo 13 prime crew commander and lunar module pilot, respectively, carry out a simulation of a lunar traverse at Kilauea, Hawaii, site. Both crew members were carrying cameras and communications equipment during the simulated traverse. They maintained contact with men in the roles of spacecraft communicators throughout the traverse. Lovell holds a scoop from the Apollo Lunar Hand Tools (ALHT), and a gnomon, also from the ALHT is deployed in front of Haise. The ALHT carrier is at left background, almost obscured by Lovell.
