Snapshots from Space

This year, we commemorate the forty-fourth anniversary of the first human lunar landing. By now, the whole world is very familiar with the high-quality Hasselblad snapshots taken by the Apollo
astronauts during their voyages. However, 35-mm cameras were also carried on some of the Apollo missions for both
surface and orbital imaging. Most of the surface 35-mm images are extreme closeups of the lunar regolith from the
Apollo Lunar Surface Closeup Camera (ALSCC; Apollo 11, 12, 14); sometimes called the Gold Camera, after its Principal
Investigator, Thomas Gold.
The Nikon camera used on board the Apollo Command Module was equipped with a 55-mm lens and was loaded with either
black-and-white or color film. During Apollo missions 16 and 17, black-and-white film was used for dim-light photography
of astronomical phenomena and lunar surface targets illuminated by Earthshine. During Apollo 17, color film was used
for documenting various activities in the Command Module.
The 35-mm frames are now scanned as part of a joint project between Arizona State University and the NASA
Johnson Space Center to scan
all of the original Apollo flight films.
Figure 2. Stereo anaglyph (get out your red-blue stereo glasses!) AS14-77-10369a,b from the ALSCC showing extreme detail of an astronaut bootprint in the fine-grained lunar regolith. The image is about 3 inches on a side [NASA/Arizona State University].
The Apollo 17 crew seems to have had the most fun with the 35-mm format! Gene Cernan,
Ron Evans and Jack Schmitt
snapped quite a few spectacular black-and-white images showing the view out of the window of their Command Module, the America.
Some of these images are a bit grainy, resulting in a very different feeling than the crisp Hasselblad photographs. They also
took numerous color candid shots inside the Command Module. It is rare to see such carefree moments during the Apollo missions,
but you can feel the relief and happiness after the astronauts so successfully fulfilled their surface mission!
Figure 3. Reiner Gamma, one of the enigmatic lunar swirls; their origin is related to localized magnetic fields within the crust. This image was acquired during lunar night, illuminated only by Earthshine, AS17-158-23894 [NASA/Arizona State University].
Many of the window shots present an oblique view across lesser known regions of the Moon. The terminator
(boundary between night and day) scenes are always captivating. Look closely at the scene below; near the
center is a shallow-sloped scallop-shaped rise. Just below and to the right are two other smaller rises -
perhaps these are low shield volcanoes? You can dig deeper by visiting the LROC QuickMap browser and see
if the NAC images can elucidate what is seen here (Natasha crater is at 19.973N, -31.157W).

Relive the incredible adventure that was Apollo, browse the Apollo 35-mm archive and the rest of the
Apollo scans (Metric, Pans; Hasselblads to follow
after the Pans have all been scanned). While browsing, map out your own next mission to the Moon! The
hard part is figuring out where to visit next. Enjoy!
