50 years later Apollo Moon Rocks set to solve more riddles
The first person to walk on the moon was the last one before coming home.
Neil Armstrong needed to raise the rocks – as much as he could carry, the more interesting he could have been. The material that he has collected will form the first samples taken from the other world of humanity.
With less than 10 minutes to go before the end of its moonwalk, Armstrong used tongs to pile up about 20 rocks in a special collection box. It was not enough to decide that he pumped 13 pounds of moon mud in the container.
Today, a large spoon of that clay sits in a sealed dish in a closed and windowless laboratory at the Johnson Space Center in Houston. This is a prized piece of the largest scientific heritage of the Apollo program: approximately 850 pounds of the Moon’s rocks.
For 50 years, research on these rocks has changed our understanding of the Moon, its causes of birth conditions and the faces of its face have been disclosed. Now, NASA has decided to release three new samples for analysis – such samples that no scientist has touched.
Upcoming experiments can be done only once on the vacuum-seal core and on a long frozen rock, the samples are opened in the exact moment. This is the reason that the material has been recovered since the Moon was recovered, said Ryan Ziegler, who curves the collection of Apollo rocks. NASA was waiting for the right scientists at the right time with the right techniques.
With this year Apollo 11’s 50th anniversary and renewed interest in the moon ahead of a proposed return mission, Jigler said, “Now is the right time.
NASA’s Lunar Sample Laboratory, shiny metal cabinets and immaculate linoleum floors were built in the 1970s, to bring the rocks back from six moon missions.
A sophisticated HVAC system, designed to keep air clean 1000 times as compared to the outside world, this facility fills an artificial artificial air. Scientists enter only after donating special white jumpsuit, caps and boots to limit contamination.
These are some of the most valuable cliffs of the solar system, Jigler said. Just look at what they have disclosed so far.
Prior to the Apollo 11 mission, scientists could not agree on where the Moon came from. It is a misfit in the solar system – much bigger than its planet relative to any other moon. Some people speculated that this was once an independent object that was “captured” by the earth’s gravity. Others have proposed that the satellite will be formed with the Earth when the planets were exiting from a primary dust disk. Many grade-school textbooks taught that it is, in fact, a drop of the Earth that was flown by the spin of our planet; The Pacific Ocean was considered a mark of this ancient loss.
As soon as the scientists saw the first Apollo rocks, they had to leave all those principles.
The Moon’s content was exceptionally ancient – 4.5 billion years old. Although they included many of the same chemicals in the form of rocks from Earth, they were poor in “volatile” – molecules such as water and carbon dioxide which evaporate when easily heated. Some of the included features are manufactured only in the catastrophe – rainfall of meteorites, explosion from volcanoes, or barrages of particles from the sun.
In a conference to discuss the preliminary findings six months after Apollo 11 returned to Earth, no one could agree on what all this evidence means.
Then, toward the end of the convention, geologist John Wood told how clues fit together. He felt that the earliest collected clay samples of Armstrong were of an unusual type of rock named Anomarthosaite, which is made of odd white color, which is formed when the mineral feldsp out of molten rock.
At some point, Wood argued that the moon would be completely covered in a Magma Sea, in which Enronothocyte rocks floated like iceberg. The molten world will have cast a terrible, blood-red glow in the night sky of the earth.
To confirm Wood’s theory, scientists needed large and better samples. He found what he wanted in 1971, when Apollo 15 astronaut James Irwin and David Scott exposed the half-pound of Enrohthoite on the rim of a pit in the northern hemisphere of the Moon.
After cleaning the dirt of the outer part of the rock, Scott realized what he was holding and started shouting. “Oh boy!”
“Look what we just got,” he said, as Irwin laughed happily. “Look what we just got! I think we found out what we came for … what a beautiful one is.”
That sample is known as “Genesis Rock” – scientists played a role in helping to know the story of the origin of the Moon. It is not far from Armstrong’s dirt dish, it sits inside its own glass case.
“These precise samples told us how to make the moon,” said Ziegler.
About 4.5 billion years ago, the theory goes that, a long-standing planet, called Thiai, was named for the mother of the Greek moon goddess, which dashed into the newly formed earth.
