    Love the early 1980s space concepts. Cute.

    Ðo you have video explaining some of the questions i have about this?How did they take such long EVA's on the moon when scuba divers have only a limited time?
    No sound, why did they hear hammer hitting the rod taking samples?
    How do space craft avoid meteorites?
    Did the astronauts have that much trust in their suits that would they would bounce, a fall around on the moons surface? Do you know any videos of them testing them for toughness?
    TIA.

      Answers to all these questions all have videos about them, on YT.
      There is no sound but it can propagate through what ever is producing it. The sound heard is what is picked up by the astronaut's microphone IN the suit, the sound was conducted through the glove and then through the air in the suit.
      The EVA backpacks carried pure oxygen fed into the suit at a pressure of approx. 0.3 atm, so the supply would be used a lot more slowly. The backpacks had about 7-8 hours of supply while the tanks were about the size of SCUBA tanks. SCUBA tanks contain air (21 % oxygen) and thus the supply is used up 5x as fast as with pure oxygen.
      Micrometeoroids cannot be avoided, but chances of a hit are extremely small, considering how big space is. A hit by anything larger than a grain of sand would cripple or destroy the craft - a catastrophe has not happened yet, proving it's a very rare thing. Large meteoroids could possibly be detected in advance and if there is a chance it might hit, a course correction can be made to avoid hitting it.

    The Moon IS Not our only natural satellite. We have heaps. Apart from that, this was enjoyable and seemed accurate.

      According to the internet the earth has only 1 natural satellite… The moon.

      @@baarni OK, maybe I am confusing with NEOs, (Near Earth Objects) otherwise known as honorary moons, second moons or mini moons. of which there are many. There are around 34,000 Near Earth Asteroids. and over 120 Near Earth Comets. Thank you for encouraging me to look further and correct myself.

      @@barnysadventures Cool👍 Yeah NEOs orbit the sun in elliptical orbits that take them from the asteroid belt between Mars and Jupiter to inside earths orbit…

    "It's a common misconception that sounds travels in space". Really? Misconception by whom? 5 year olds?
