Apparently, not only the earth that has garbage. On the Moon also found a pile of garbage.
It is said that based on Wikipedia data, the waste in the month if the total total can reach 400,000 pounds, equivalent to 181,000 kilograms of calculations on earth.
This number is still a polemic among scientists, but William Barry, Head of the Historian US Space Agency (NASA), found it reasonable to see the trash left by NASA.
Barry says that both manned space missions such as the Apollo program and the unmanned ones like the US, Russia, Japan, India and Europe leave trash on the Moon.
It is known from the findings of moon waste such as flags, hammers, Falcon fur, olive gold pieces, and pieces part of the moon explorers. This is a relic of the launch of the space shuttle in 1971.
In addition, there are also Lunar Crater Observation and Sensing Satellite (LCROSS) satellites still lagging on the moon.
These objects are deliberately left on the moon. Therefore, to bring it back to Earth requires more fuel. In addition, the objects are no longer used after the mission succeeded.
But apparently, the garbage that is on the moon becomes important. The garbage proves that the surface of the moon can be visited, unlike previous scientists who think that the surface of the moon in the form of quicksand sand because too often leveled by space rock.
Barry also requested that municipal waste is not only considered a waste and unused object. The garbage will one day become an important archaeological trace. The hope, scientists in the future the opportunity to look proof of the existence of space missions on the moon.
The spacecraft missions trailing on the moon can also be used as further research material.
Reflector laser belongs to Apollo 11 crew, for example. Things that still lean on this month can still be used to measure the distance of the earth and the moon. How to shoot laser to reflector. From there, it is known that every year, the distance of the earth and the moon increases by 3.8 centimeters or the moon moves away from the earth.
