- That also was a result of the 3 seconds it takes for a radio signal to travel to and from the moon, since radio waves are another form of light waves. Since moonlight is reflected sunlight, it originates at the Sun's surface 93 million miles from the Earth/Moon system.It takes about 8 minutes for that trip, so the short, final hop from the Moon to the Earth is trivial by comparison.ince moonlight is reflected sunlight, it originates at the Sun's surface 93 million miles from the Earth/Moon system.

How Far is the Moon? The USSR launched the first mission to the moon, Luna 1, in 1959. With no propulsion system, the sphere-shaped satellite was hurled into space, and took only 34 flight-hours to make the trip. After its flyby, the satellite went into orbit around the sun, between the orbits of Earth and Mars.

- The time it takes to get to the moon depends on the speed of the spacecrafts. The Apollo 11 was launched July 16, 1969 from Kennedy Space Centre and landed on the moon on July 19th. It took a total of 3 days, 3 hours and 49 minutes to fly to the Moon and 3 days to return to Earth.Afterwards, on April 11, 1970, Apollo 13 was launched from the Kennedy Space Centre and landed on the Pacific Ocean after traveling around the Moon on April 17th.he shortest trip to the Moon took place in January 2006 by the NASA Pluto probe New Horizons. With the speed of 58,000 km/hr, it only took 8 hours and 35 minutes to get to the Moon from Earth.

- Pulsed Light delivers wavelengths from 500 to 1200 nm while Laser can deliver only 1 wavelength at a time. Pulsed Light can deliver total pulse durations up to 25 msec or 1235 msec while most Laser can deliver pulse durations up to 40-100msec (and 1 machine can deliver 1000 msec but at only 800nm) Pulsed Light's larger light beam size allows for faster treatment and deeper light penetration.

No, The Moon Landings Werenât Faked. In the grand scheme of things that really is not very far AT ALL, considering the size of the universe, but it's not exactly a trip to the Moon either. A trip to the Moon (which is NOT far at all) with current technology (nowhere near the speed of light of course) takes about 3 days one way. Secondly, it being a 'habitable' planet, doesn't exactly mean it's an island paradise.. From the data it would seem the planet is similar to Earth in its dimensions, with a diameter about 1.2-1.4 times that of ours, and a mass about three times as large.

How long does it take for the moon to orbit the earth? The orbit of the Moon around the Earth is completed in approximately 27.32 days. The more precise figure is 27 days, 7 hours, 43 minutes, 11.6 seconds. The period between consecutive phases is longer, at 29.53 days, because the position of the Earth and Moon changes as Earth orbits around the Sun.

- I believe I remember reading that the Saturn V rocket took three days to make the trip to the moon. The moon is about 220,000 kilometers from the Earth. You do the math. (The number I am getting in my head is a little less than one kilometer per second, or about 3,000 km/h, or about 2,000 mi/h). I think that the Chinese are planning on repeating this particular experiment. We will see what they come up with.

How Long Does It Take To Get To The Moon? Rockets can get you going much faster. The first spacecraft to make the run was the Soviet Luna 1 probe. It completed a flyby in 1959. Luna 1 wasn't trying to get into orbit. It was there to whiz past the Moon and take a few pictures as it went. It completed the journey in only 36 hours, traveling at a speed of 10,500 kilometers per hour.

- Because 6 trillion miles is such a huge number, we really need to break it down to understand just how far it is. So let's start by looking at a light second. Since light moves at 186,000 miles per second, a lightsecond is 186,000 miles. The moon is about 1.3 lightseconds away. Since the circumference of the earth is about 25,000 miles, light could travel all the way around the earth 7 and a half times in one second. A millisecond is a thouandth of a second. So a lightmillisecond is 186 miles.

How long would it take a rocketship to reach Venus? The Moon is 385000 km from Earth (in average). The average distance of Venus is 108000000 km from Earth. So the ratio is #108000000/385000 \approx 280#. The rocket used to go to the Moon, the Saturn V, took 3 days. Then, a similar rocket, would take #3*280=840# days or #2.3# years. Of course a mission on Venus would probably be done with a better technology and fastest rocket, so this is just a guess.

- The vastness of space has opened our minds, but its size has limited our search. We want to explore distant worlds, but how can we travel faster so we can go farther into space? Jet speed certainly isn’t the answer. Imagine traveling by jet to the moon from Earth, about 386,000 km (240,000 miles). A jet traveling at 1,600 km/h (1,000 mph) would take about 240 hours or about 40 days to reach the moon.

Solar observation Another early observation was of solar prominences, described in 1185 in the Russian Chronicle of Novgorod. In the evening there as an eclipse of the sun. It was getting very gloomy and stars were seen ... The sun became similar in appearance to the moon and from its horns came out somewhat like live embers.

DISA mulls laser system for satellite communications The Lunar Laser Communications Demonstration was able to transmit data from the moon to the Earth at a rate of 622 megabits/sec, which was six times faster than previous state-of-the-art radio systems. An all-optical satellite communications system is potentially capable of significantly increasing data transfer rates. Also, because the system doesn’t use the radio frequency spectrum, it won’t have to deal with spectrum allocation or mutual interference due to satellite spacing.

How long does it take for the Sun's light to reach us?  (Beginner) Thank you for your time. The sun's light takes about 8 minutes to reach the Earth after it has been emitted from the sun's surface. The time it takes for light to reach planets in our Solar System (not the Milky Way, which is our galaxy) varies from about 3 minutes for Mercury, to about 5.3 hours for Pluto. There is nothing out in space to prevent the sun's light from going infinitely far, in principle.

How Long Does It Take for Light From the Moon to Reach the Earth? It takes light from the moon's surface approximately 1.3 seconds to reach the Earth. This is also the amount of time it takes for sound to travel from the Earth to the moon. That means that communication from the Earth to an astronaut on the moon has a 2.6-second delay.
