The moon is full of trash. But we do not need to carry an all-out Swachha Bharat Abhiyaan like mission on the moon surface as some of the junk still serve a purpose there.
SOURCE OF ALL THE TRASH ON THE MOON
The moon surface contains a lot of garbage left behind by the humans between 1969 and 1972 when the Apollo program was still active. Other space-exploring agencies of countries like Japan, Russia, India, Europe, and the USA also contributed to the trash on the moon in one form or another.
HOW MUCH GARBAGE IS THERE ON THE LUNAR SURFACE?
The trash on the lunar surface is so much that it would weigh up to 400,000 lbs (181,437 kg) on earth. The moon is littered with numerous lunar orbiters, gold olive branch, a flag kit and lunar debris. There is also a hammer and a falcon feather on the lunar surface which were used to demonstrate that the gravity works the same on both the items.
WHAT PURPOSE DOES THE GARBAGE ON MOON SERVE?
The satellites sent to the moon achieved marvellous observations. For instance, the Lunar Crater Observation and Sensing Satellite studied the hydrogen and confirmed the presence of water on the moon. By using a laser-range reflector, the researchers from earth can measure the distance between the moon and our planet (and that is how we found out that the moon is shifting away from the earth at a rate of 1.5 inches per year).
Apart from that, the objects left on the moon can also help study how the items weather on the lunar surface. Also, the trash left behind by the man shows how space travel has evolved over the years. And who knows, when and how this trash become a treasure.
