![]() I’m going to leave your open, but don’t let me. “Okay, 540 ( 77510-26) is the first bag of selected samples (location in Fig. “Yeah, but mine’s been down all the time, Bob,” countered Cernan, “…except in the shade.” That’s sort of an infrared shield.” The problem, if one existed, would be UV radiation as Parker should have known however, I rarely let sunlight in, directly, having grown up in the sunny Southwest. “You’re probably letting in a lot of infrared through without having that gold visor down, too. “Roger,” Parker said, not resisting the impulse to chide me on my visor. “You notice the temperature difference with that high Sun angle?” commented Cernan. Once bagged, I did my usual three-rotation twirl to close the bag. “Picking,” I replied, tersely, as I leaned into the slope, with the scoop handle in my midsection, and bagged a sample. …My primary tools: the dust brush and the hammer…and my head. “You know what? I’m getting tired of dusting. …I wouldn’t do this for anybody but you, you know that.” And, I repeat, we’d like to get some dusting of the mirror and the lens of the TV TCU and the TV. “Should have it (TV), Bob,” Cernan reported. The original view can be accessed at the QuickMap website. The LROC QuickMap view showing the locations of the Sta. (graph produced by the LROC QuickMap).įig. 12.103, probably because of the gradual upturn in the terrain (of about 1 in 20 m) masking its rim between 10 m and 30 m in front of me. The noteworthy point is the 25 m diameter crater between ~32 m and ~57 m. distance of a line between me and boulder “ c”. The boulder in this view is therefore comparable to looking at the LM Challenger at one end of an American football field from the other end!

The reseau marks are 10.3º apart in the original frame (AS17) and if we use the distance of 108 m, the horizontal dimension is ~7.1 m whereas the vertical dimension is ~5.9 m (as a check on the photogrammetric trigonometry, the actual horizontal dimension can be measured directly with the LROC QuickMap tool at 0.5 m/px resolution, 5 measurements gave 7 ± 0.89 m). By computing the size of boulder “ c”, deceptive distances and perspectives on the Moon can be demonstrated. The boulders on the horizon in the distance at middle left are the fragments of the Sta. The bright area between my shadow and the boulder above is a result of the intense back-scattering from the regolith. 7 boulder (not fully framed at middle right) and boulder “ c” at left. The down-sun view looking west, which shows the relation between the Sta. A higher resolution, unlabeled view in a separate window, is available here. Three specific samples discussed below are indicated. The oval continues the area of shallow depression marked in Fig. To the left of the Rover some of its tracks can be seen. Cernan is working at the LRV, which was not fully framed. For a higher resolution, unlabeled view in a separate window, click here. The text spans the area where I picked up the indicated samples described below. The oval outlines a shallow depression with my footprints. This image may give the reader a better idea on how hard it is to judge distances on the Moon. For a higher resolution view in a separate window, click here. The distance between me and boulder “c” is ~108 m as measured on the LROC Quickmap. This view looking south includes the large, squarish boulder at top right labeled “ c” in Fig. The series of photos from my Pan 23 sequence is shown as quarters in these next four figures. 21651-55 are the before images of the many small rocks I would sample.įig. Then we can take another one for location work.” This panorama consists of AS16-64. “Bob, I’m going to take the pan at 11 feet, so you can see the fragments that we’re going to pick up here. “131.” I must have misread the indicator, as I had taken a number of photographs during our traverse to Station 7. ![]() “And, Jack, what’s your frame count?” interrupted Parker. “There is another one of our blue-gray breccias, I think, over there: re-crystallized breccias with some of that crushed anorthosite in it. ![]() ![]() …See what kind of variety we can get here.” …You take a pan before, and we’ll start picking up some of those samples, and I’ll take a pan afterward. “You want me to help you with the dusting, Geno?” Planimetric map of the Station 7 layout, showing the locations of Pans 23, 24 the locations of various rock samples and the position of the LRV with respect to the location of the large boulder (black oval) that was sampled (Modified from ]).
