I remember a serious technical person commenting that mining on the moon would be impractical because it would create clouds of dust that would take days or weeks to settle because of the low gravity. Ignoring the fact that there’s negligible atmosphere and dust particles would fall at the same speed as an anvil. 1.6 m/s^2. The dust “clouds” would fall to the surface in a few seconds.
But yeah, “no gravity” is incorrect. I seem to remember we were taught in school it is about 1/6 of Earth’s gravity. Otherwise Neil and Buzz would have floated away. To infinity and beyond.

There is gravity on the moon, just much smaller than on earth. If you throw something, providing you aren't the hulk, it will come down eventually.

But it was not as remarkable as many movies. They showed the first footprint, a couple of shots of them hopping around on the moon. It showed Neil throwing a bracelet that had belonged to his daughter into a deep crater. I have never heard of that happening. I think they may have invented that scene. That was really the focus of the EVA activity on the lunar surface. Nice shot of the LM with the flag. And when they left there is a shot of the LM and the retroreflector. But it was brief. No shots of them lugging stuff around, taking samples ( one I guess) or assembling and installing the flag. This whole anti patriotic thing is some cooked up fake controversy. Plenty of US flag waving by citizens of other countries when they were watching it on TV. Flags on uniforms, USA on the side of the Saturn V etc etc. Of course the right loves to pick on the left at every opportunity (and vice versa) and Hollywood is probably 80% left. So someone strained at gnats to find something to become apoplectic over and it went viral. <lent> From: Ken Hohhof Sent: Saturday, October 13, 2018 8:23 AM To: 'AnimalFarm Microwave Users Group' Subject: Re: [AFMUG] OT Movie Review What about the soundtrack? Ron Howard took some liberties with Apollo 13 but still everyone should watch it once a year. If you don’t find it inspirational check to make sure you have a pulse. Oh, and great soundtrack. Another docudrama that is not 100% historically accurate but everyone should watch is Thirteen Days. I would say anyone who thinks the Cold War was the best of times must not have lived through it, but how to explain Vladimir Putin?

Some spoilers here but I think everyone probably knows how the story ends. First impression was I did not like the style of photography. Too many shaky closeups. One sure fire way to make me choke up, my nose burn and cause my eyes to leak is to expose me to formaldehyde. For some reason and am super super duper hyper sensitive. Other wise I am pretty stoic. The other sure fire way to cause this reaction is if I am exposed to material covering Apollo 1, Challenger or Columbia. Odd emotional reaction every time. I guess because I was so into all of the Mercury, Gemini and Apollo missions when they were happening. I built models. Listened to the moon landing on the radio. Totally geeked out to all of this stuff back in the day. They did not do a very good job in communicating the horrible end to the lives of the Apollo 1 astronauts. Perhaps they did not want to traumatize the audience, but they made it seem like – boom – its all over. The reality was much much more gruesome. They overdramatized the uncommanded roll spin up of Gemini 8. It was a big time emergency but the graphics had it spinning like a dryer on spin cycle. I think max RPM was about 1 rev per second before Neil Armstrong finally isolated it to a reaction control rocket firing continually. He killed the circuit breakers and was able to manually halt the roll. I have spun airplanes at this rate. It is not going to cause you to pass out. If he was not able to stop the increase in roll rate it would have done so, but they guy knew the spacecraft and he knew there were only so many things that could cause this. He did some basic troubleshooting and saved the day. But the biggest thing that I disliked was them showing the inside of the space craft. Panels, annunciators and switches that were dirty, worn and smudged. Like some old bulldozer at a gravel pit instrument panel. Almost as if they built the props from stuff they got out of an aircraft bone yard. In reality, those things were brand spanking new and sparkling clean. The photos exist... Not sure why they chose the grunge. Even the headliner of the spacecraft and their ear muff thingies looked grungy and used. They also showed a Chicago connector on one of the hoses connected to the capsule. Pretty sure a generic jackhammer air connector was not used. They glossed over the 1202 alarm a bit too much. (The book Digital Apollo is a great read about this). They were more concerned about that than the movie lets on. They showed a scene where Neil flew over a super deep crater while running out of fuel. That never happened, he was just picking out a spot between the boulders. So, if you care about fine detail accuracy, you may not enjoy this too much. It is not nearly as good as a PBS special by any stretch of the imagination. _____ -- AF mailing list [email protected] <mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com _____ -- AF mailing list [email protected] <mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] <mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
