Astronaut training in the Reduced Gravity Walking Simulator. This position meant that a person's legs experienced only one sixth of their weight, which was the equivalent of being on the lunar surface.
... that Apollo astronautswalked on walls(pictured) before walking on the Moon? Source: [1]: "A person lies sideways, supported by slings around their waist and rib cage, which are attached to very long cables connected to a mounting point somewhere above them. Instead of touching the floor, their feet actually touch a wall that is slightly tilted, so it’s not exactly perpendicular to the floor. This gives them a fake “ground” to practice walking, running, and jumping on without feeling the full force of Earth’s gravity."
Clear at 100px: - I wonder if we should extract a cropped version of the photo for use in DYK just to remove the negative space around the people. We only get 100px here, so I think it might be worth it to zoom in a bit. Thoughts?
QPQ: Done.
Overall: It took me a minute to find where the hook is mentioned in the article, and I think that's because the article mentions the walls instead as a surface "9.5° angle from horizontal". Should this be "9.5° angle from vertical" instead, since it's almost vertical? Other than these couple of questions, looks good to me. @Artem.GBsoyka (t • c • g) 03:54, 19 July 2024 (UTC)
Hey Bsoyka, thanks for the review! I'll think about the crop, or maybe css crop can be used? Will experiment with it a bit later from a laptop. Regarding the vertical or horizontal angle, this is from a sourceIf we want a simulated gravitational field (and free-fall acceleration) of 1.63 m/s2, then the person and floor would need to be leaning 9.6 degrees from being completely horizontal. I think 9.5 is from a 1965 paper, will check it again. Let me know if it's confusing, and I will think about better phrasing. Artem.G (talk) 10:11, 19 July 2024 (UTC)
@Artem.G: Not sure CSS cropping can be done here since we have to use the {{Main page image/DYK}} template—probably easier to just extract a new version solely for DYK, more details on that here. Now with the phrasing, I understand it more with that source because it says the person is almost horizontal, which makes much more sense. I think the relevant sentence in the article needs to be adjusted to say that, because it doesn't make sense to just say the walkway is almost horizontal. Bsoyka (t • c • g) 14:29, 19 July 2024 (UTC)
@Bsoyka:, paraphrased a bit, let me know if it's still confusing, though I don't think I'd understand it without a photo. What do you think about the cropped variant? Artem.G (talk) 17:22, 19 July 2024 (UTC)
@Artem.G: Still maybe a little confusing, but better. And I think the cropped photo is perfect. Calling this one good on my end—thanks for the changes! Bsoyka (t • c • g) 17:27, 19 July 2024 (UTC)
