Moon Landing Could Have Infected the Earth With Lunar Germs, Say Astronauts (independent.co.uk) 180

Posted by BeauHD from the space-bugs dept.
PolygamousRanchKid quotes a report from The Independent: A mistake made during the Apollo 11 moon landing could have brought lunar germs to the Earth, astronauts have revealed. When the three astronauts flew to the Moon and back, exactly 50 years ago this month, NASA worked hard to ensure that no bugs were brought back from the lunar surface. All three of the Apollo 11 crew were put into special clothes, scrubbed down and taken to a quarantine facility where they lived until scientists could be sure the Earth would not be contaminated. But interviews from a new documentary -- filmed by PBS and revealed by Space.com -- show that the plan to keep Earth could easily have failed, and that space bugs could have got into the Earth's atmosphere despite Nasa's best efforts. The astronauts noted that Nasa did not think there would be anything alive on the Moon that could be brought back down to the Earth. But the precautions were taken in case there were. "Look at it this way," astronaut Michael Collins said. "Suppose there were germs on the moon. There are germs on the moon, we come back, the command module is full of lunar germs. The command module lands in the Pacific Ocean, and what do they do? Open the hatch. You got to open the hatch! All the damn germs come out!"

    From an evolutionary viewpoint, there's not much risk. If indeed there are germs on the moon, they will be adapted to those very harsh conditions. Put them on Earth and in those very different conditions they'll be no match for competing organisms who are fully adapted.

    And anyway rocks fall from space all the time (from dust to large asteroids) with no meaningful contamination.

    • In a sense, Earth could be regarded as harsh as well for organisms living on the moon. The biggest problem is the oxygen, which is highly aggressive and kills most live that is not adapted to it. Didn't the bacteria that released the oxygen into the atmosphere essentially kill themselves in the process as the oxygen levels got too high?

      • Carbon based life needs to breathe in either co2 or o2, so far as we know. There's neither on the moon. But if you can imagine a life form that breathes helium and thrives on solar radiation, maybe there could be something there.

          Just a couple of points:

          One, the helium on the moon is in the rocks, and extractable through mining not breathing.

          One point five, the moon does not have any atmosphere to breathe anyways.

          And two, there is no rationale in a creature that breathes helium because helium is too nonreactive, and the energies it requires to get it to react with something as might be required for a biological process like breathing would probably be detrimental to the life of any creature that tried to breathe it.

          • Point two is most important, because maybe you'd have some kind of life form in the rocks.

            • The point of point two is that the energy needed to make biological use of helium would exceed the use you got from the helium.

              Bacteria already can live in rocks and "eat" only non-organic materials. If they had some huge energy source for doing weird chemistry, they would not benefit from processing helium with it. Nor does helium even offer a convenience would to create a reaction and get rid of energy.

    The reason that terrestrial germs are dangerous to humans is that they've spent millions of years evolving to attack animal immune systems. HIV is extremely well-targeted to avoid the human immune system, for instance. And what germs lose by being "designed" stochastically and through the brute-force process of evolution, they make up for in vast numbers of replications and mutations to find new ways to attack us.
