This is explained in the Apollo Program Summary Report. A floating command module has two stable positions; stable II is upside-down and undesired. It was discovered that three identical uprighting bags was not enough to get out of the stable II position, so the Z-axis bag was made smaller: 4.4.4.4 Uprighting system [...] In addition to the overall weight ...

The first Block I version of the capsule used three bags of the same diameter (43 inch). The later Block II used one smaller bag (34 inch). The volume of the small bag was 49.43 % of the larger ones. So they wanted to try a smaller bag with half the volume and calculated a 34 inch diameter bag. Source: https://airborne-sys.com/wp-content/uploads/2016/10/...

Overall it seems that the NYT article has garbled the details: although the initial low-angle sunlight made Surveyor Crater look too steep, the estimated angle of about 11 degrees proved manageable by sidling down the rim. From the Apollo 12 Lunar Surface Journal transcripts and commentary by the astronauts (https://www.hq.nasa.gov/alsj/a12/a12.html): ...

I'm very sure that this is the Lunar Equipment Conveyor. The Lunar Equipment Conveyor (LEC) is a device which the astronauts will use during the EVA to transfer equipment to or from the ascent stage. It may also be used by the crewmen as a safety tether when moving down the ladder or as an aid in ascending to the ascent stage. The LEC is a 60 foot ...

To answer question 4 (this is mostly reformulating my comments on the question): Was it ever used on any Apollo mission, either to haul someone out of a crater or for something else? No The Lunar Surface Journal's Sampling at Head Crater and Bench Crater entry includes commentary between Pete Conrad, Alan Bean (the LM crew) and Eric M. Jones (who wrote/...

It helps to do the math. Tangent 21 degrees = .384 = 38.4 % grade. This is around 5 times steeper than most anything you'll see driving around the Rocky mountains of Western USA. Very difficult to climb out of, even when not wearing a bulky space suit. Important to remember, even though moon gravity is 1/6th earth (1.62m/s$^2$), there is no "terminal ...
