In 1969, Apollo 11 carried three astronauts to the moon. This was the fifth manned space mission in human history and the first human mission to land on the moon.

Six hours after landing on the moon, Armstrong said: That's one small step for a man, one giant step for mankind. giant leap for mankind.). ?

During the 2 hours and 30 minutes of lunar activity, Armstrong and Buzz Aldrin conducted a series of scientific research work on the moon.

The above are plots that we are familiar with, but what we don’t know is that when Armstrong and Buzz Aldrin boarded the return capsule, in order to save fuel for the return capsule rocket, they flew on the moon A vomit bag, two urine collectors and a feces collector were left on the surface.

NASA later stated that during the Apollo manned lunar landing mission, astronauts left 96 bags of human excrement on the lunar surface in one day.

After the Apollo program, due to various reasons, no country carried out manned missions to the moon. However, in 2017, Trump announced the restart of manned moon landings.

There are many reasons why Trump announced the resumption of manned moon landings, but one of the reasons is to recycle the 96 bags of diapers left by humans on the moon.

Don’t get me wrong, this is not a lunar environmental protection plan, but a very important scientific research.

Diapers and the Moon

We know that the birth and survival of life require a specific environment. The environment on the moon is completely different from that on the earth, so it is difficult for life to survive on the moon.

The reason why there is no life on the surface of the moon, scientists speculate, is because the moon has no atmosphere, ocean, and magnetic field.

The magnetic field can protect life on the planet from high-energy charged particles, and the ozone layer in the atmosphere can block ultraviolet rays, allowing life to live on the surface of the planet. A deep enough ocean, like the atmosphere, can also block ultraviolet rays. Therefore, when studying cosmic objects, if there is a liquid ocean on a certain planet and there are hot springs under the ocean, this means that life may be born on this planet.

To sum up, there are no conditions for the birth of life on the moon, so in our understanding, there is no life on the moon.

However, as a precaution to prevent the astronauts from bringing back unknown pathogens from the moon, scientists quarantined them for three weeks. The astronauts did not leave the quarantine until August 13, 1969. District, interviewed by the media and cheered by the people.

However, later on, people began to think in reverse: If creatures on Earth were taken into space, would they survive?

To this end, people have brought many organisms into space, and also brought some plant seeds into space to test whether they can germinate in space. These studies later achieved fruitful results, and even The breeding method of space fruits was started.

In 2014, the European Space Agency brought more than 200 microorganisms into space and conducted tests in space for 18 months. The test results showed that some microorganisms not only survived, but were also able to interact with Reproduce as on Earth.

So people thought of the 96 bags of diapers left on the moon. These 96 bags of diapers contained human excrement, and human excrement contained microorganisms.

These 96 bags of diapers have been on the moon for 51 years. If the microorganisms inside are still alive, scientists can study what changes have occurred in these microorganisms and what impact the lunar environment has on these microorganisms. This might help us establish a human base beyond Earth.

That’s why Trump’s announcement to restart the manned moon landing plan included picking up 96 bags of diapers.

Why do humans seldom land on the moon?

In 1972, when the astronauts on the last lunar mission returned to Earth, then-US President Richard Nixon gave a speech saying: This may be the last time humans land on the moon in this century.

After that, although humans will still carry out lunar projects, no humans will ever land on the moon again. The reasons are complex, but in general there are two points.

The cost of manned moon landing is relatively high. The maturity and difficulty of unmanned detector technology are constantly decreasing, which means that all tasks that humans can perform can be achieved with the help of unmanned detectors. Moreover, human landing on the moon has a certain probability of failure, and a series of human life activities in space have to be solved. As a result, the cost of manned landing on the moon is much higher than that of unmanned probes.

One more thing, before Armstrong, Aldrin and Collins carried out the first manned moon landing, no insurance company was willing to insure them due to their high risk.

They signed hundreds of envelopes and postcards, just in case, and asked friends to stamp launch and moon landing dates. If they really can't come back, these signatures are enough to make the family a fortune. Later, those envelopes were worth up to $28,500 each.

Manned landing on the moon is not an unachievable plan. Although it is difficult to land on the moon, humans have already achieved it in the last century. Moon, so the fact of landing on the moon itself has no particular appeal.

Therefore, no country regards manned landing on the moon as its top priority, and if it is necessary to demonstrate national strength through manned landing on alien planets, then landing on Mars is the best choice.

Due to various reasons, no country has implemented a manned moon landing program since 1972. If Trump can launch manned spaceflight and bring back diapers left on the moon, it may help humans understand habitable planets from another perspective and prepare for immigration to outer space.
