Is there a mirror on the Moon?

It's amazing how much light our moon reflects. Having a few mirrors doesn't hurt, though. They're there because of the Lunar Laser Ranging experiment. In 1969 Buzz Aldrin placed a two-foot wide panel of mirrors on the Moon.

Why were reflectors placed on the Moon?

One reason engineers placed the reflector on LRO was so it could serve as a pristine target to help test the reflecting power of panels left on the Moon's surface about 50 years ago. These older reflectors are returning a weak signal, which is making it harder to use them for science.

Can you reflect a laser off the Moon?

One of the experiments taken into space on Apollo 11 was called the Lunar Laser Retro-Reflector, and it still works even today (though perhaps not as well as it did), just like it did in a 2010 episode of "The Big Bang Theory.

What are the mirrors on the Moon for?

Here's how it works: A laser pulse shoots out of a telescope on Earth, crosses the Earth-moon divide, and hits the array. Because the mirrors are "corner-cube reflectors," they send the pulse straight back where it came from.

What did NASA leave on the Moon?

Besides the 2019 Chinese rover Yutu-2, the only artificial objects on the Moon that are still in use are the retroreflectors for the lunar laser ranging experiments left there by the Apollo 11, 14, and 15 astronauts, and by the Soviet Union's Lunokhod 1 and Lunokhod 2 missions.

Is the US flag still on the moon?

Images taken by a Nasa spacecraft show that the American flags planted in the Moon's soil by Apollo astronauts are mostly still standing. The photos from Lunar Reconaissance Orbiter (LRO) show the flags are still casting shadows - except the one planted during the Apollo 11 mission.

Has a Bible been left on the moon?

Two hundred of the bibles were kept aboard the Apollo 14 command module "Kitty Hawk," which remained in lunar orbit. The remaining 100 descended to the moon's surface with Mitchell and mission commander Alan Shepard on board the lunar module "Antares" to the Fra Mauro lunar highlands.

Can I see the flag on the Moon with a telescope?

Yes, the flag is still on the moon, but you can't see it using a telescope. I found some statistics on the size of lunar equipment in a Press Kit for the Apollo 16 mission. The flag is 125 cm (4 feet) long, and you would need an optical wavelength telescope around 200 meters (~650 feet) in diameter to see it.

What did they discover on the Moon?

Molecular water, H2O, was found in Clavius Crater, one of the largest craters visible from Earth in the Moon's southern hemisphere. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places. SOFIA offered a new means of looking at the Moon.

Can you see leftover equipment on the moon?

That means that there would be no way to discern the Lunar Excursion Module or any of the other equipment left on the moon. It is just too small to pick up, even with the world's best telescope.

How long would it take a laser light sent from Earth to bounce off a mirror on the moon and return to Earth?

They're akin to really long yardsticks: By precisely timing how long it takes laser light to travel to the moon, bounce off a retroreflector and return to Earth (roughly 2.5 seconds, give or take), scientists can calculate the distance between the moon and Earth.

What happens if you point a laser at the moon?

The laser pointer on the moon is basically the same. Each photon travels to the moon at the speed of light, but the image of a dot that they form on the surface moves 20 times faster. No physical laws are broken, because nothing physical is actually traveling faster than light. It's just an image.

Is there light on the moon?

Unlike a lamp or our sun, the moon doesn't produce its own light. Moonlight is actually sunlight that shines on the moon and bounces off. The light reflects off old volcanoes, craters, and lava flows on the moon's surface.

Does the moon shine its own light?

The Moon gets its light from the Sun. In the same way that the Sun illuminates Earth, the Moon reflects the Sun's light, making it appear bright in our sky.

What temperature is on the Moon?

Taking the Moon's Temperature

Daytime temperatures near the lunar equator reach a boiling 250 degrees Fahrenheit (120° C, 400 K), while nighttime temperatures get to a chilly -208 degrees Fahrenheit (-130° C, 140 K). The Moon's poles are even colder.

Can a moon have a moon?

Yes, in theory, moons can have moons. The region of space around a satellite where a sub-satellite can exist is called the Hill sphere. Outside the Hill sphere, a sub-satellite would be lost from its orbit about the satellite. An easy example is the Sun-Earth-Moon system.

Is there a dark side of the Moon?

Capturing the dark side

The 'dark side' of the Moon refers to the hemisphere of the Moon that is facing away from the Earth. In reality it is no darker than any other part of the Moon's surface as sunlight does in fact fall equally on all sides of the Moon.

Who owns the Moon?

The short answer is that no one owns the Moon. That's because of a piece of international law. The Outer Space Treaty of 1967, put forward by the United Nations, says that space belongs to no one country.

Can the Moon crash into Earth?

Long answer: The Moon is in a stable orbit around Earth. There is no chance that it could just change its orbit and crash into Earth without something else really massive coming along and changing the situation. The Moon is actually moving away from Earth at the rate of a few centimetres per year.

Can you see footprints on the Moon from Earth?

In reality, all Earth-based telescopes have a much lower practical magnification limit around 300 times. This means that under typical seeing conditions from the surface of the Earth and using a large telescope, the footprints on the surface of the moon are something like 1,000 times too small to be seen.

Who's human remains are on the moon?

To date, the late scientist Eugene Shoemaker is still the only person whose remains have been sent to the Moon. Even casual stargazers are likely to recognize Shoemaker's name from the famed Comet Shoemaker-Levy 9 (which had broken into fragments) that impacted Jupiter in 1994.

Is there a military base on the moon?

It took until 1969 before a man—astronaut Neil Armstrong—would take a giant leap for mankind on the surface of the Moon, but there is still no base of any kind on the Moon.

Are there people on the moon right now?

Although we haven't put a human on the lunar surface since the 1970s, there are now regular crewed missions to space.

How long will footprints on the Moon last?

Image above: The first footprints on the Moon will be there for a million years. There is no wind to blow them away.
