This marks the longest one-way communication via laser, as the light made its way across the 240, 000 miles between the Earth and Moon.
More likely, craters on both the earth and the moon were the acne scars left by volcanic eruptions.
The phases of the moon occur due to cycles among the moon, the earth and the sun.
If all goes well, the next target will be L1, the point 85% of the way to the moon where the gravitational pulls of moon and Earth balance.
ECONOMIST: The Americans may still go to the moon before the Chinese
In 1609, Italian philosopher and physicist Galileo Galilei used descriptions of Lippershey's gadget to build his own telescope, and with it he was able to observe the Earth, the Moon and several planets in our solar system in detail for the first time.
Dr Amy Mainzer, principal investigator on the Neowise (Near-Earth Wise observations) project at the Jet Propulsion Lab (JPL) in California, said that "estimating the ages and origins of the asteroids should help us to correlate events on Earth and impact craters on the Moon with what is going on in the Solar System".
And the fact that the sun and moon were particularly close to the Earth at precisely the same time -- well, that made the tidal bulges even bigger.
Donald Olson and Thomas Lytle of Southwest Texas State University have calculated the tidal forces exerted on the earth by the sun, the moon and the planets.
In his version (From the Earth to the Moon, 1865, and its sequel, All Around the Moon, 1870), an aluminum craft launched from central Florida achieves a speed of 24, 500 miles per hour, circles the moon and splashes down in the Pacific.
The other way of doing things is for the company to retrieve smaller asteroids, put them into orbit around Earth or the moon, and then dissect them at its leisure.
It was discovered in 1986 and it takes a convoluted horseshoe path around our planet as it is tossed about by the Earth's and the Moon's gravity.
If the 295 trillion megabytes (or, exabytes) of stored information were saved on CD-ROMs, the stack of CDs would stretch from the Earth to beyond the moon, according to Hilbert and Lopez.

Certainly it claims it wishes, like President John Kennedy 50 years ago, to send people to the surface of the moon and return them safely to Earth.
The data could shed light on how impacts shaped the evolution of the Moon and other bodies such as the Earth.
BBC: Nasa reveals new information about moon probes crash sites
As Laine explains in the video, an elevator from the surface of the Moon to a rendezvous point between the Earth and its satellite is actually possible using current technology.
ENGADGET: Liftport turns to Kickstarter for space elevator experiment (video)
Tide: periodic rising and falling of large bodies of water resulting from the gravitational attraction of the moon and sun acting on the rotating earth.
The problem NASA has faced is that since the Eagle landed on the moon and Apollo 11 returned safely to the earth the American people lost interest in our manned space program.
FORBES: Who Says America Is Falling Behind In The Space Race?
For example, instead of the lunar rendezvous method that NASA chose for the Apollo program, the player can opt for Earth-orbit rendezvous or even direct-ascent where a single giant spacecraft lifts off from Earth and lands on the Moon.
My company, Moon Express, is focused on the next stage of commercial space beyond low Earth orbit, and is already developing early precursor robotic missions in partnership with NASA to explore the Moon and learn how to develop its resources for the benefit of life on Earth.

Energy resources that can be harvested in space for the benefit of Earth include helium-3 that occurs in abundance on both the Moon and asteroids and is ideal for new small fusion plants, as well as solar energy that can be collected and transmitted in concentrated form to Earth.
In turn, that should help resolve questions about how the Moon, the Earth, and other planets in the solar system evolved in the first place.

The intention was to give the US a crew-carrier and rocket technology that could go beyond low-Earth orbit to more distant targets, back to the Moon and further.
The television pictures on board were designed to begin operating when the rocket came within 2, 500 miles (4, 023km) of the lunar surface - 40 minutes before impact - and then send an image of the Moon back to Earth every 13 seconds.
Without it, we might still fancy the Earth situated in the center of the cosmos, with the sun, the moon and all the stars orbiting around us.
The modular tin cans that took us to the moon and back, and have kept us in Low Earth Orbit (LEO) ever since, will eventually be superceded by full-scale space cities.

As we were leaving the museum through the Rose Center for Earth and Space, past stunning images of the Apollo astronauts working on the surface of the moon, I asked her, for the record, why she'd never felt the urge to visit before.
Also, over strong London coffees, Isaac Newton, Christopher Wren and philosopher Robert Hooke met to discuss the movement of Earth and Dr John Wilkins mooted, for the first time ever, the idea of flying to the moon.
These upheavals will, supposedly, be the result of a planetary alignment, as the combined gravitational influences of the moon, Mercury, Venus, Mars, Jupiter and Saturn wreak havoc on the earth.
And the Moon is close by and always in the sky, unlike the asteroids that flyby the Earth at incredible velocities or inhabit orbits tens of millions of miles away that take years to reach.
