Our Moon

A:

One of the main reasons the United States sponsored a mission to the moon was because of the space race with Russia. Russia was the first country to put an artificial satellite in space, which caused a lot of embarrassment for the U.S.

    Q: How long does it take to get to the moon?

    A: The Apollo 11 astronauts on the famed 1969 mission took 3 days, 3 hours and 49 minutes to go from launch to close lunar orbit, typical of manned missions. Unmanned spacecraft employ a much wider range of travel times.

  • Why does the moon look orange?

    Q: Why does the moon look orange?

    A: Any time the moon appears orange in the sky, it's because of light diffusion and refraction in the atmosphere. When the moon is low in the sky, the blue light reflected from its surface is scattered in the dense atmosphere, giving the moon a reddish-orange cast.

  • What are the phases of the moon?

    Q: What are the phases of the moon?

    A: The phases of the moon are: new moon, waxing crescent, first quarter, waxing gibbous, full, waning gibbous, third quarter and waning crescent. After the waning-crescent phase the moon returns to the new-moon phase and the cycle starts again. The complete cycle takes a little over 29 days.

  • What happens during a lunar eclipse?

    Q: What happens during a lunar eclipse?

    A: A lunar eclipse happens when the Earth passes between the moon and the sun. Lunar eclipses cast a shadow on the moon due to the Earth's location. From the perspective of the moon, the Earth completely blocks the sun.

  • What is the temperature on the dark side of the Moon?

    Q: What is the temperature on the dark side of the Moon?

    A: Temperatures on the dark side of the moon average around negative 280 degrees Fahrenheit. This is do in part to the moon's lack of an atmosphere; there is no insulation to hold heat (on the far side) or soften the sun's rays (on the sun facing side).

  • Where does the moon rise?

    Q: Where does the moon rise?

    A: The moon rises in the eastern sky and sets in the western sky because of Earth's rotation. Its rising and setting positions vary throughout the year from northeast/northwest to due east/west to southeast/southwest.

  • What is the weight of the moon?

    Q: What is the weight of the moon?

    A: The moon has a mass of 7.35 x 10²² kilograms. It is only about 60 percent as dense as Earth, and as such, the moon's mass is only 1.2 percent of Earth's. Thus, it would take the mass of 81 moons to equal the mass of Earth.

  • What objects did astronauts leave on the moon?

    Q: What objects did astronauts leave on the moon?

    A: Thanks to six moon landings, hundreds of objects are still scattered across the surface of the moon: golf balls, boots, cameras, javelins, sculptures, photographs, and a golden olive branch. Because the moon doesn't have an atmosphere, most of these objects will remain preserved until something impacts that area of the moon.

  • How was the moon formed?

    Q: How was the moon formed?

    A: The most popular theory regarding lunar formation is that a Mars-sized planetoid slammed into the Earth and flung molten debris into orbit around 40 million years after the solar system was created, according to scientists at the National Aeronautics and Space Administration (NASA). This is called the giant impact theory.

  • How much would you weigh on the moon?

    Q: How much would you weigh on the moon?

    A: According to the Argonne National Laboratory, a human being weighs approximately one-sixth as much on the moon as he does on Earth. If an individual weighs 180 pounds on Earth, that weight is converted to 30 pounds on the moon.

  • What is the meaning of a yellow moon?

    Q: What is the meaning of a yellow moon?

    A: When the moon appears orange or yellow, it simply means that the observer is looking at it through more layers of atmosphere. Similar to the way in which the sun will look orange or red on the horizon, when the moon is low in the sky, the light from it will have to pass through more of the blue-absorbing atmosphere to reach the viewer's eye. By this time, only yellow, orange and red light will remain unabsorbed.

  • How long does it take the moon to rotate on its axis?

    Q: How long does it take the moon to rotate on its axis?

    A: One lunar day, the length of time it takes the moon to complete a full rotation on its axis, is equivalent to 28 days on Earth. This is also the amount of time it takes for the moon to complete its orbit around the Earth.

  • Do full moons really make us crazy?

    Q: Do full moons really make us crazy?

    A: Humans have long believed that there is a connection between a full moon and erratic behavior, but there is no scientific proof that this is the case. Even though no real evidence exists of the moon's crazy-making powers, many continue to believe that the two things are connected. This is known as "illusory correlation," in which people imagine that they see a logical connection where there isn't one.

    A: One of the many differences between the Earth and the moon is simply that the Earth is a planet and the moon orbits the Earth as its satellite. The Earth's circumference is 24,873.6 miles, while that of the moon is 6783.5 miles.

  • What is the difference between a new moon and a full moon?

    Q: What is the difference between a new moon and a full moon?

    A: When the moon is full, the moon is at its brightest, and the entire disk is visible. New moons occur when the Earth comes between the moon and the sun, resulting in a moon that is completely obscured by the Earth's shadow and is barely visible in the night sky.

  • Why does the same side of the moon always face Earth?

    Q: Why does the same side of the moon always face Earth?

    A: Though the moon does rotate around its axis, the speed with which it completes these revolutions match the amount of time it takes to orbit around the Earth, leading the same side to be faced toward Earth at all times. This process takes a about month, meaning the moon's days are as long as an Earth month.

  • What went wrong with Apollo 13?

    Q: What went wrong with Apollo 13?

    A: As the source of the iconic phrase, "Houston, we've had a problem," the Apollo 13 mission went from an intended moon landing to a narrowly averted disaster when one of the oxygen tank exploded as the shuttle was en route to the moon. This event occurred on April 14, 1970, three days after the shuttle's launch. After the explosion, the shuttle's crew, consisting of commander Jim Lovell, Jack Swigert and Fred Haise, worked with NASA mission control in Houston, Texas to successfully get themselves back to earth without major injury.

  • Are blue moons actually blue?

    Q: Are blue moons actually blue?

    A: While the name "blue moon" conjures up a vivid, colorful image, the term actually refers to those times when there are two full moons in a single month; that second full moon is referred to as the blue moon, though its color is likely to be the same as it ever is. It is possible for the moon to have a bluish appearance, but this is usually due to atmospheric changes on earth, such as smoke or ash in the upper atmosphere as the result of fires or volcanic activity.
