How far would male ejaculate go on the moon? You may need to incorporate a penis airlock in order to make it work (ie get it out of the spacesuit). A friend suggests this might make it go farther. ---

NASA has long been puzzled by a long period of silence during the first moon walk, broken only by one of the astronauts suddenly blurting out: “Look at how far we’ve come!” ---

Actually, an ordinary penis won’t work. You need a pressurized space penis. ---

Well, I read the average distance on earth is 1m and the average ejaculatory speed is 45 km/hr. The moon’s gravity is 1/6th that of earth’s, or 1.624 m/s². From these points of data you should be able to work it out using kinematic equations. ---

The maximum recorded distance on Earth is about 5 metres (this was a question in a pub quiz I went to last week). ---

To the inside surface of the space suit, I think. ---

Google says the average ejaculation goes at 28 mph. If we assume a penis 80 cm above the lunar surface, pointed 45° upward, I get about 98 meters. ---

I guess this must be what Neil Armstrong’s family meant when they issued that statement last night urging people “to explore and push the limits, and to selflessly serve a cause greater than themselves.” ---

But if it’s ejecting from a pressurised environment to a vacuum, it will have a lot more thrust due to the differences in pressure, wouldn’t it? I mean, if you poke a hole in a spacesuit, the air gushes out. I think the effect will be greater than that due to lower gravity. ---

In all seriousness, I’d say there’s maybe a 75/25 chance somebody knows this already. That is, there was more than enough room inside the Apollo LM for an essentially long underwear-only wearing astronaut to have, ah, yanked one out for fun & science & the greater glory of capitalism! Giving that these guys were mostly fighter jocks & test pilots, one the one hand I can see at least one of them maybe going for it. But on the other, I can see it being more than a little too homo-erotic for them too. :eek: ---
