This photo shows an early version of a planetary rover. Although technical reports have been found that describe a triple cab rover, none include this particular configuration. If you worked on this rover or can provide any details about it, please log in with your JPL username at left (if you have one) and post a comment.

On August 13, 1969 six Apollo astronauts (Bean, Carr, Conrad, Gibson, Irwin, and Scott) visited JPL and were briefed in building 179 about the Surveyor 3 lander that would be found on the surface of the Moon. In preparation for removing the camera and other spacecraft parts, several of them attempted to cut a piece of structural aluminum tubing and found that tin snips were inadequate for the job. Online photo albums contain more photos taken during this visit. (JPL Internal Access only. Log in with JPL user name and password.)
The consensus among people who commented on this photo: the astronauts are, from left to right, Pete Conrad, David Scott, and Alan Bean. Conway Snyder is in the background wearing a bowtie.

This July 1967 photo (375-937B) shows the ultra-high vacuum Molsink (Molecular Sink) chamber in building 82. It was designed to provide a nearly ideal simulation of the vacuum and cold sink of space for surface effects testing. The Molsink is partly disassembled, so you can see the liner bulkhead, Moltrap, inner liner, and the lower part of the external pressure vessel. The 1970 cutaway drawing below is photograph number 357-1321B.
For more information about the Molsink, see JPL TM 33-540 or TR 32-1446.

Lunar Surface Rendezvous
In the early 1960s, JPL and other NASA centers were involved in studies about a variety of manned lunar landing and return mission systems and concepts. This illustration shows one option for a lunar surface rendezvous technique. More information about this study can be found in JPL Technical Memoranda 33-52 and 33-53.
Can you guess when this artist’s conception was created, and identify the proposed mission concepts?

Taken in about 1940
This photo looks west from the arroyo to the JPL site, near the spot where the east gate bridge now crosses the arroyo. The small buildings seen in the photo housed a workshop, office and laboratories.
Do you know when and where this photo was taken? Hint: The sign reads, “Bridle path, DANGER, do not pass beyond this point. C.I.T.”

High Speed Kerr Cell
Photograph Number 371-581A
5/16/1951
A Kerr-cell electro-optical shutter was developed at JPL as the first step in the design of a high-speed camera capable of shutter speeds up to 50,000 frames per second on 70-mm film. R.B. Bowersox, shown in this photo, wrote several technical reports about the project, and in September 1965 he became the manager of Section 9, Instrument Development. Contact the JPL Archives for more information.
