Our Apollo@50 series continues with the first truly scientific exploration of the Moon -- the Apollo 15 mission. With new hardware including an orbiting observatory platform on the Command Service Module, the first lunar rover, and an upgraded, lunar module, Astronauts Dave Scott and Jim Irwin were able to geologically explore the mountains of the Moon at the Hadley-Apennine landing site that featured 14,000 high peaks and a spectacular canyon: Hadley Rille.

In orbit, Command Module Pilot Al Worden made an extensive geologic reconnaissance with a fully loaded scientific instrument bay including high-resolution cameras. To look back on this mission, Dave talks with the two moon walker's daughters: Tracy Scott and Jill Irwin Christensen. Farouk El-Baz joins Dave to talk about his training and mentorship for his good friend, CMP Worden and Jim Head from Brown University describes his work in training and working with the Apollo 15 astronauts on a very complex mission.

Finally, Lead Flight Director Gerry Griffin gives Dave his perspective on the epic explorations of the lunar astronauts from his seat at mission control in Houston.
