moon landing

mm no posts for this in last few days is this the end, well all good things come to an end I guess.

And if you think thats a good investment, I've got a bridge in Brooklyn I'd like to sell you!

How come nobody wants to know why Buzz has a bad heart?

What was probably the least efficient work that either Armstrong or Aldrin did came during the final minutes when Armstrong used a piece of equipment called the Lunar Equipment Conveyor or LEC to get the rock box up to Aldrin in the cabin. Essentially, it was a clothesline. After Aldrin hooked the LEC to a pulley in the cabin, Armstrong hooked the rock box to the LEC, backed away from the LM to make the line taut, and then pulled hand-over-hand as the box bounced its way up to Aldrin. It was hard work. At the start of the EVA, Armstrong's heart rate had been about 120 beats per minute and it had declined more or less steadily toward a low of about 80 as he took pictures at the rim of the crater east of the spacecraft. With time running short, he began a hurried collection of rocks and soil and his heart rate climbed to the 120-140 beat range. And then, while he was using the LEC, his heart rate shot up to 160 beats per minute and Houston had to call for a short rest. Other Apollo Commanders didn't have to work quite so hard when they were using the LEC. The excitement of the moment and the rush of collecting the bulk sample surely were contributing factors in Armstrong's case. But the LEC was an inefficient tool and, beginning with Apollo 14, the astronauts started carrying at least some of their gear up to the cabin by hand. The 16 and 17 crews did away with the clothesline LEC entirely - having decided that it was more trouble than it was worth - and hand carried everything except a bag containing their camera. That bag they raised and lowered with a hook and lanyard, a humble rope that somehow managed to inherit the LEC's name.

Alright, I'll bite. What are you talking about? This? Why is this significant?

Helium-3 (aka Tritium).

Oh, you're looking for conspiracy theory. Wrong forum, but to put a fine point on it, the various moon conspiracy theories are absurdly false.

No not a wrong forum, wrong assumption, on your part. I am asking a serious question. Why does hauling 4 pounds of rocks make a, in condition astronauts heartbeat go to 160 beats per minute? My question is logical, if you can give me a logical answer, I will listen....

There is only one thing besides very heavy physical activity that can raise a heart beat of a in conditon human body. What do you think that might be?

I figured there would be a scientific reason how this could happen, thats what I want to know.

Excitement or fear can raise the heart rate. That's not what you implied in your previous posts. You clearly have an explanation in mind. So lets have it: What do you think the explanation is?

Also, your scuba analogy is flawed. The problem is that the amount of oxygen available with each breath from a scuba tank is many times larger than what an astronaut gets from his tank. As a result, its much more tiring working on the moon.

Are you telling me that the equipment the atronauts used, was equivelent to breathing, climbing over the top of K2 8,000 feet altitude? I would think that Nasa would have developed equipment to breathe normally on the surface of the Moon and take that into consideration for duration of stay.

Well you are in the vaccum of space. The difference in pressure is greater if you have air at ATP. Maybe the space suit can't handle that pressure???

In vaccum of space, there is no pressure, there is nothing to press. If there was a whole in a spacesuite it would empty it quickly. We breathe at 14.7 pounds a square inch at sea level. Although at 8,000 feet above sea level the pressure might be half that. I do not think it is reasonble to believe Nasa would design a spacesuite for astronauts to only fill to 7 pounds per square inch and as a result, make the astronauts work hard and breath at marathon heartbeat levels.
