OT: aahh..maglisod jd ka anang rodsky doc!..in my opinion if nabutang pa ni sa iyang teritoryo ang imong thread..i don't want to comment nlang..nway it seems na nindot ni inyong discussion pero murag lisod nani subayon da..cge padayon.

salamat Ramini.
nakakita ka sa gidak-on sa oxygen tank sa likod sa astronaut?
ikumpara sa gidakon sa dala sa mga divers.
ang standard nga dala sa divers mo last lang og 1.5 hours usa ka tank.
pila sila ka oras sa moon?
usa ka adlaw.
thats 24 hours more or less
kung kato kadako nga tank, murag at least 8 ka tangke nga ingon ato iyang mahurot sa usa ka adlaw nga compressed air. pero wala ka kakita nga nagcharge, nagkargag oxygen through a hose, or nag-ilis og tangke sa oxygen.
unya kung dugay ka magginhawag compressed air sama sa usa ka adlaw, dunay tendency nga mahubog ka sa nitrogen sa air nga magkataas ang concentration.
Nagsige na unta to silag katawa sa moon tungod sa nitrogen.
Ug, asa paingon ang carbon dioxide nga ilang gi-exhale?

taudtaud na ko nag agi agi diri nga thread, kung sa baryo pa ni, nag tigbasay na tingali ni pero kay forum ra man, tigbasay lang sa hunahuna ug masamdan lang ang mga garbo.
doc, naa lang ko gamay i ambit. di kaayo ko suheto kay gamay ra ko ug kinaadman. naatol lang nga sa akong pag panarbaho, i had served with someone who was part of the gemini and apollo projects himself. through the years, we became friends, and from that friendship i learned about the technical stories about the apollo missions.
it happened doc.. it simply happened.
youtube may show you otherwise, and you get those visual cues as your givens, perhaps proceed from there to create your solution.
i arrived from a different path. once in my life, i was rubbing shoulders with a gemini and apollo engineer, and some other technical personalities involved in hush-hush projects like area 51.
pero sagdi lang, bisaya ra kong dako. pila ra man ako kinaadman. paambit lang ko diri sa inyo hisgot hisgot. seldom ra ko muapil ug tigbasay.
Food of the Apollo 11 Lunar Landing – Eat Me Daily1.) How did they eat without taking off their suit and without being exposed to radiation.?
Re: how did apollo 11 astronauts go to the toilet?2.) How will they urinate wearing a pressurized suit?
3.) How will they go to the bathroom wearing a pressurized suit?
NASA Apollo 11 - Neil Armstrong Spacesuit4.)How do they breathe and how much air did they carry on their small and tight lunar module?
Isnt that an interesting question?
lipay naka?
What a Space Suit Does
By creating an Earth-like environment within the suit itself, space suits allow humans to walk around in space in relative safety. Space suits provide:
Pressurized Atmosphere
The space suit provides air pressure to keep the fluids in your body in a liquid state -- in other words, to prevent your bodily fluids from boiling. Like a tire, a space suit is essentially an inflated balloon that is restricted by some rubberized fabric, in this case, Neoprene-coated fibers. The restriction placed on the "balloon" portion of the suit supplies air pressure on the astronaut inside, like blowing up a balloon inside a cardboard tube.
Most space suits operate at pressures below normal atmospheric pressure (14.7 lb/in2, or 1 atm); the space shuttle cabin also operates at normal atmospheric pressure. The space suit used by shuttle astronauts operates at 4.3 lb/in2, or 0.29 atm. Therefore, the cabin pressure of either the shuttle itself or an airlock must be reduced before an astronaut gets suited up for a spacewalk. A spacewalking astronaut runs the risk of getting the bends because of the changes in pressure between the space suit and the shuttle cabin.
Oxygen
Space suits cannot use normal air -- 78 percent nitrogen, 21 percent oxygen and 1 percent other gases -- because the low pressure would cause dangerously low oxygen concentrations in the lungs and blood, much like climbing Mt. Everest does. So, most space suits provide a pure oxygen atmosphere for breathing. Space suits get the oxygen either from a spacecraft via an umbilical cord or from a backpack life support system that the astronaut wears.
Both the shuttle and the International Space Station have normal air mixtures that mimic our atmosphere. Therefore, to go into a pure oxygen space suit, a spacewalking astronaut must "pre-breathe" pure oxygen for some period of time before suiting up. This pre-breathing of pure oxygen eliminates the nitrogen from the astronaut's blood and tissues, thereby minimizing the risk of the bends.
Carbon Dioxide
The astronaut breathes out carbon dioxide. In the confined space of the suit, carbon dioxide concentrations would build up to deadly levels. Therefore, excess carbon dioxide must be removed from the space suit's atmosphere. Space suits use lithium hydroxide canisters to remove carbon dioxide. These canisters are located either in the space suit's life support backpack or in the spacecraft, in which case they are accessed through an umbilical cord.
Temperature
To cope with the extremes of temperature, most space suits are heavily insulated with layers of fabric (Neoprene, Gore-Tex, Dacron) and covered with reflective outer layers (Mylar or white fabric) to reflect sunlight. The astronaut produces heat from his/her body, especially when doing strenuous activities. If this heat is not removed, the sweat produced by the astronaut will fog up the helmet and cause the astronaut to become severely dehydrated; astronaut Eugene Cernan lost several pounds during his spacewalk on Gemini 9. To remove this excess heat, space suits have used either fans/heat exchangers to blow cool air, as in the Mercury and Gemini programs, or water-cooled garments, which have been used from the Apollo program to the present.
Micrometeroids
To protect the astronauts from collisions with micrometeroids, space suits have multiple layers of durable fabrics such as Dacron or Kevlar. These layers also prevent the suit from tearing on exposed surfaces of the spacecraft or a planet or moon.
Radiation
Space suits offer only limited protection from radiation. Some protection is offered by the reflective coatings of Mylar that are built into the suits, but a space suit would not offer much protection from a solar flare. So, spacewalks are planned during periods of low solar activity.
Clear Sight
Space suits have helmets that are made of clear plastic or durable polycarbonate. Most helmets have coverings to reflect sunlight, and tinted visors to reduce glare, much like sunglasses. Also, prior to a spacewalk, the inside faceplates of the helmet are sprayed with an anti-fog compound. Finally, modern space suit helmet coverings have mounted lights so that the astronauts can see into the shadows.
Mobility Within the Space suit
Moving within an inflated space suit is tough. Imagine trying to move your fingers in a rubber glove blown up with air; it doesn't give very much. To help this problem, space suits are equipped with special joints or tapers in the fabric to help the astronauts bend their hands, arms, legs, knees and ankles.
Communications
Space suits are equipped with radio transmitters/receivers so that spacewalking astronauts can talk with ground controllers and/or other astronauts. The astronauts wear headsets with microphones and earphones. The transmitters/receivers are located in the chestpacks/backpacks worn by the astronauts.
