The lasers were eventually sent back to Earth from the Moon



The Earthlings are known to intervene with lasers and attempt to make them work for different purposes. When Communicate with these extraterrestrials using a laser is a challenging idea and a difficult project to succeed; however, sending them to the moon and bringing them back was a real success.

A group of scientists from NASA finally got their signal back from the moon, thanks to the Lunar Reconnaissance Orbiter (LRO). NASA used infrared lasers developed by their colleagues from the Géoazur team at Côte d’Azur University, France.

However, they waited over 10 years for the answer, because the LRO reached the Moon in 2009.

How it works?

This is not the first time that a reflector has been used for such a purpose. Scientists have been relying on reflectors in Moon missions since The Apollo program back in 1

969.

Basically, a laser beam is sent to the mirror that is reflected from Earth, then the time it takes to return is measured. It also helps in calculating distances between Earth laser stations and lunar reflectors. It is known that a few important discoveries related to the moon have been made thanks to this.

One of them is the fact that the Moon has a liquid core, is concluded by the small swaying movements it produces as it rotates on its own.

Another discovery made by magnetic field measurements was that small objects had a magnetic field long ago. It raises the question of what the inside of the moon is made of.

What is the problem here?

It’s time RLO has to figure out why the 50-year-old reflectors installed by the Apollo 11 and 14 crews send a fairly low signal to Earth today.

The old reflectors are thought to be covered with dust from microscopic asteroid effects on the Moon. And that dust is blocking the beam reaching the reflector properly. Scientists now plan to compare the mismatch between the light emitted by the LRO and old panels by using a computer model to find out if dust is the real problem.

Although successful experiments and related studies to be announcedScientists have not gathered more information.
