Get the smell of gunpowder as Earth no perplexing moon dust

Moon dust perplexing mystery smells

According to the NASA website 14, disclosure, moon dust looks as if the Earth is as usual the soil, but they don't like appearances. The researchers found that the moon dust is a lot of complex composition of viscous substances, and give off a mysterious smell. However, for decades, scientists have been unable to uncover the moon dust odour of the answer. Now, the United States "Apollo" Lunar spacecraft of the astronauts go to the front, to disclose them to feel the taste of the moon dust.

Smell the smell of gunpowder with unit

United States "Apollo 17" astronaut Jean · Cernan, referring to the moon dust, said: "this is a surprising things, they give off a gunpowder explosion ended breath!" moon dust looks like glints like soft, it is a strange powder. "Apollo 16 astronaut Charles Duke ·" said: "moon dust does have a strong odor. I feel that smell like bullets fired at the dissemination of General. "" Apollo 16 "astronaut John · Yang said:" moon dust of taste and not very bad, but very special. ”

Each "Apollo" astronauts have smelled the smell of the moon dust. Moon dust is a viscous substance that can stick in shoes, gloves and other exposed surface. Each time the moon walk, before re-entering the lunar module, no matter how hard the astronaut's dust material slapped, they still go into the cabin. Once the astronauts took a helmet and gloves, they can smell that confusing by the smell of the "Moon".

Contact astronauts on dust allergy

This special feeling let "Apollo 17" astronaut Jack · shumi-became the first to be recorded on the astronauts to the moon dust allergy. Shumi-remember this experience, said: "after the first space walk, I remove the helmet and found himself on the moon dust with a strong reaction. My turbinate bone began to swell up until a few hours later slowly fade. In the second and third spacewalk, me the recurrence of such problems, but there is no original serious degree. ”

However other astronaut says no such symptoms. To this end, shumi-laughed and said: "they just don't want to admit it. The pilot believed that, once recognized allergy, they will no longer skies. Shumi-only "is a geologist, no such scruples. Shumi-revealed that he's very sensitive turbinate bone, maybe this is why other astronauts reacted strongly without him.

Odd to the Earth no flavor

But surprisingly, once they are sent back to Earth, the moon dust does not have any smell. NASA Johnson Space Center Moon samples laboratory has hundreds of pounds of moon dust. There, the lab technician lovren powdered with hands smelled the Moon rock, then smelled the air, finally also smelled the own hand.

He said: "they smell like you really do not like the smell of gunpowder. "Don't" Apollo "astronaut just unfounded guess? lovren and other experts believe: back to Earth's moon dust" become quiet. " "Apollo" astronauts brought back from the Moon's all rock samples has been working with the humidity, the air in contact with oxygen. Any smell of chemical reactions already ended.

Prior to this, the experts did not expect this. Astronauts used special "thermos" container vacuum to save the Moon samples. But the moon dust jagged edges sometimes accidentally stabs container seal so that oxygen and water vapor in the spacecraft returns to the Moon for three days the gradual penetration. No one can estimate the exposure on the influence of the moon dust. Shumi said: "we need to study these dust on the moon. Only where we can find its features like it why? how to smell and landing vehicle, environment reacts? "

Suspected source of the odor is still a mystery

But apparently, the moon dust and powder are not the same thing. Lovren, Lunar soil does not find inflammable organic molecules. A match point moon dust explosion will not occur. The Lunar soil is constituted by any material?

In fact, nearly half of the moon dust is impacting the Moon meteorites the vitreous silica. In addition, such as olivine and pyroxene minerals such as iron, calcium and magnesium are enriched with moon dust. It is completely different with the gunpowder, scientists still don't know how this kind of smell.

NASA plans to 2018 again will astronauts on the moon. Perhaps the scientists will be unveiled the moon dust mysterious odor. But it is also possible to wait until our next generation, will have more time and more advanced tools to uncover the moon dust mystery of odour.
