Opening credits with NASA logo (0:11) and title. A simulated CapCom dialogue between the flight captain and ground crew completing pre-flight go/no go checks with a view outside the flight window (0:51). Employees working on computers at Mission Control (1:00) at the Manned Spacecraft Center (MSC) in Houston, Texas. Astronauts in a simulated lunar landing capsule (1:21). A screen showing the flight on a radar tracker (1:31); a printout of coordinates (1:33). Flight controllers, systems experts, and medical specialists at Mission Control tracking spacecraft performance, flight paths, and astronauts’ heartbeats on various pieces of equipment (1:44). Apollo 4 spacecraft exiting Earth’s atmosphere with a countdown in the background (2:07). Satellites and tracking systems at the communication center at Goddard Space Flight Center in Maryland (2:37). The Mission Control Center in Houston, the command and control point for all phases of Apollo flights (2:50). Ground stations in Hawaii, which are part of the tracking network to link spacecraft and Mission Control (2:58), along with ships (3:02) and aircraft (3:04). An Apollo spacecraft visualization showing a module detaching from the main craft (3:29). Three deep space stations to augment communication in Goldstone, California (3:39), Madrid, Spain (3:44), and Canberra, Australia (3:46). Eighty-five-foot dual antennae from the stations (3:58), which are located 120 degrees apart to ensure line-of-sight communication with the spacecraft. Several methods of spaceflight communication are shown: radio signals (4:14), radio telemetry and 2-way communications (5:00), Spacesuit communication packages transmit astronauts’ vital signs (5:14). An onboard TV camera to observe the crew (5:32). The simulated lunar module descending to the moon’s surface (5:44). A simulation of astronauts erecting an antenna on the moon outside the lunar module (5:57). In case of emergency, emergency voice and hand-keyed Morse code (6:33) are available. A visualization of the lunar module rendezvous and docking with the command module (6:38), when line-of-sight communication is available. During the command module’s entry into Earth’s atmosphere, communication is impossible due to ionization of air particles (7:01). Parachutes open to slow the module’s descent (7:23). A diagram showing the Essex ship “ON STATION” during recovery (7:29). During a simulation, astronauts communicate with frogmen after the command module lands in the water (7:39). Astronauts disembark from a Navy helicopter during a simulated recovery (7:52). The film ends by emphasizing the importance of good communication, especially between humans, during a lunar mission. Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.

Entirely film backed, this material is available for licensing in 24p HD, 2k and 4k.
