Unlike past missions, LADEE will be using lasers instead of radio waves to communicate with mission control.

Moon Facts
Deep Impact

The moon's deepest craters are 4,500 m (15,000 feet). The South Pole-Aitken basin on the moon is an abyss that could engulf the United States from the East Coast through Texas.

Our Drifting Moon

Did you know the moon is moving away from the Earth at a rate of 1.5 inches per year?

First Interaction with the Moon

In 1940, the Diana Project was the first experiment to successfully bounce radio signals off the moon.

Prince of Tides

There are two high tides and two low tides every day on every beach on Earth. This is due to the moon's pull.

Tiny Temblors

"Moonquakes" are millions of times less powerful than earthquakes.

Once in a Blue Moon

About every 2.5 years an extra full moon, called a "Blue Moon" occurs.

The term Blue Moon is believed to have originated in 1883 after the eruption of Krakatoa. The volcano put so much dust in the atmosphere that the moon actually looked blue in color. This was so unusual that the term "once in a Blue Moon" was coined.

Inverted Moon

As the astronomical telescope with its inverted image came into use, astronomers adopted the habit of representing the way they saw the moon -- upside down. This practice was followed until very recently. Lunar images are now constructed and stored digitally and can be displayed at any orientation. The moon is now typically shown right side up.

Moon Gods

Most ancient religions had a moon god or goddess. One Roman moon goddess was named Luna, and this is why many modern words associated with the moon have "Luna" as their root.

Mighty Minotaur

LADEE will be launched on an five-stage Minotaur V rocket. The first three stages of the Minotaur V are former Peacekeeper ballistic solid rocket motors. The fourth and fifth stages are commercial motors.

The Wolf Moon

When the snows were deep in January, wolf packs would often howl near Native American villages, prompting the title "full wolf moon" for the first full moon in January (according to climatologist Brent McRoberts of Texas A&M University).

Long Gone

There are no active volcanoes on the moon now. The moon's volcanoes have been extinct for billions of years.

Moon Day

A lunar day (or the time it takes from sunrise to sunrise) on the moon is approximately 708 hours.

Surface Boundary Exosphere

The atmosphere of the moon, called a surface boundary exosphere, is likely the same type of atmosphere found on many other planets.


There are two types of earthquakes that happen on the moon: deep moonquakes and shallow moonquakes.

Moon Rocks

Between 1969 and 1972 six Apollo missions brought back 382 kg (842 pounds) of lunar rocks, core samples, pebbles, sand and dust from the lunar surface. In addition, three automated Soviet spacecraft returned important samples totaling 300 g (approximately 3/4 pound).

Who's the Bunny Girl on the Moon?

Apollo 11 Buzz Aldrin to Mission Control, "Okay. We'll keep a close eye out for the bunny girl."

One Small Step ...

In 2009, a NASA team restored the first grainy video of Neil Armstrong's first step on the moon.

The Moon Festival

Did you know the Chinese and Vietnamese have a festival each year to celebrate the moon?

Massive Impact Basin

Did you know the largest impact basin in the Earth-moon system is the South-Pole-Aitken basin on the moon measuring 2,500 km in diameter?

Moon Rocks

Rocks from the moon are similar to three kinds of igneous rocks that are found here on Earth: basalt, anorthosites and breccias.
