Can my laser reach the Moon?

The typical red laser pointer is about 5 milliwatts, and a good one has a tight enough beam to actually hit the Moon—though it'd be spread out over a large fraction of the surface when it got there. The atmosphere would distort the beam a bit, and absorb some of it, but most of the light would make it.

What happens if you point a laser to 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.

How long does it take the laser beam to reach the moon?

The distance of the Moon from the Earth has been already determined very preciselyusing a laser as a source of light. A laser light beamed at the Moon takes 2.56 s to return after reflection at the Moons surface.

Does laser light reach space?

The light from a laser in space would continue on forever unless it hit something. However, if you were far enough away, you wouldn't be able to detect the light. A projectile would also continue on forever unless it hit something. Lasers produce light that can be tightly focused.

Can a laser reach Mars?

Engineers from Canada claim that a laser-based system to reach Mars could tremendously cut the time it takes to reach the Red Planet. According to NASA's estimates, it would take about 500 days for humans to reach Mars at current speeds.

Can a handheld laser hit the moon?

The typical red laser pointer is about 5 milliwatts, and a good one has a tight enough beam to actually hit the Moon—though it'd be spread out over a large fraction of the surface when it got there. The atmosphere would distort the beam a bit, and absorb some of it, but most of the light would make it.

How far can a 1000mw green laser go?

So we return to the question: “how far can I see my laser beam for?” As mentioned there will be many different factors to consider, but here is a basic guideline. 200mW green lasers will be visible for more than 10 miles and blue lasers 1,000mW or more will also be visible for 10 miles or more on a clear line of sight.

What color laser is strongest?

As a general rule, green lasers are 532nm are 5-7X brighter than any other laser color, at the same power. Whether blue, red, purple/violet, or a light color like yellow, green is the best at strength for visibility.

How far does a 532 nm laser go?

Green Laser Pointer, 532nm, Range to 3,000 Ft.

Can a laser destroy a mirror?

Ryan Hoffman, Counter-Directed Energy program manager, says that mirrors protect well against low-power lasers. “However, reflective surfaces are not 100 percent reflective,” he says. “The small amount of laser energy that's absorbed will heat the mirror and cause damage.”

Can telescopes see the American flag on the moon?

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.

How far can a green laser go?

The 1 mW red pointer has a glare distance of 255 feet, compared to the same power green laser, which can cause glare at 490 feet.

Does laser travel faster than light?

Laser pulse travels 300 times faster than light.

How far can a Class 3 laser go?

The Nominal Ocular Hazard Distance (NOHD) for the most powerful Class 3R visible-beam laser (4.99 mW) with a tight beam (0.5 milliradian divergence) is 104 ft (32 m).

How fast can laser propulsion go?

The scientists estimated that a 0.035-ounce laser sail with a 4-inch sail driven to speeds of about 112,000 mph (180,000 km/h) could reach Mars in 20 days, compared with the 200 days for NASA's Perseverance rover; Jupiter in 120 days, compared with five years for NASA's Juno probe; Pluto in less than three years, ...

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 you see equipment left 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.

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.

Can a laser shoot down a missile?

The U.S. Navy reports that it has shot down a simulated cruise missile using an all-electric laser weapon for the first time ever. The Navy has used a laser to shoot down a missile before - but long ago, and with a much different technology.

Will lasers replace bullets?

For certain niche scenarios, lasers might prove themselves ideal. It seems unlikely, however, that they will ever outright replace missiles and bullets, as they do in so much sci-fi warfare. "No conventional weapon is a panacea," said Douglas Beason, former associate lab director at Los Alamos National Laboratory.

Will laser guns ever exist?

After decades of R&D, as of January 2020 directed-energy weapons including lasers are still at the experimental stage and it remains to be seen if or when they will be deployed as practical, high-performance military weapons.

What's the most powerful laser?

Magurele Laser in Romania officially becomes the most powerful laser in the world. The laser at Magurele, near Bucharest, Romania marked a world premiere after reaching the highest power, 10 PetaWats.
