    Moon
In summary, it is possible for astronauts to leave equipment on the moon and use it for experiments, such as the Lunar Laser Ranging Experiment. This experiment has been used to measure the moon's distance with millimeter precision and even aid in the orbit calculations of the Lunar Reconnaissance Orbiter. This information has been reported by reputable sources and has been used to debunk theories of the Apollo mission being a hoax.

Found this on youtube, wasnt sure if this is actually possible, i never heard of the astronauts actually leaving stuff on the moon.

Yes. If you leave a mirrored target shaped like the intersection of 3 walls of a cube, the light will come directly back to the area from which the pulse was fired.

Look up the apollo missions on wikipedia. You can find plenty of info on the experiments left behind.

It's a good point to mention to Apollo hoax believers, they tend to start mumbling when you point out that there is proof that stuff was left behind.

Yes it is incredible, even 40 years later. As a consequence Nasa can measure the moon's distance to millimeter resolution( maybe more , not sure). They also use it to help calculate the orbit of the Lunar Reconnaissance Orbiter. I have to assume it has been used to impress a woman at one point in time also.

But, not with the precision achievable with LLRE. It's been nailed down to a matter of millimeters now.
 

1. Can a laser really shoot to the moon?

Yes, a laser can shoot to the moon. Lasers are capable of traveling long distances through the vacuum of space, making them an ideal tool for communication and scientific research.

2. How strong does a laser have to be to reach the moon?

The strength of a laser needed to reach the moon depends on several factors, such as atmospheric conditions and the distance between the laser and the moon. Generally, a laser with a power of at least 1 watt is needed to reach the moon.

3. Will a laser beam reach the moon instantly?

No, a laser beam does not travel instantly. It travels at the speed of light, which is approximately 299,792,458 meters per second. This means that it would take about 1.3 seconds for a laser beam to reach the moon.

4. What is the purpose of shooting a laser to the moon?

Shooting a laser to the moon has several purposes, including communication, scientific research, and measuring the distance between the Earth and the moon. It can also be used for laser ranging, which involves bouncing a laser beam off of reflectors on the moon's surface to measure its exact location and movement.

5. Are there any risks or dangers in shooting a laser to the moon?

There are minimal risks or dangers in shooting a laser to the moon. However, it is important to follow proper safety protocols and regulations to prevent any potential harm to the environment or other objects in space. It is also important to ensure that the laser is not pointed at any aircraft or satellites passing through its path.
