10 Facts about Moon

10 Facts about Moon:


1. The Moon is drifting away from the Earth:The Moon is moving approximately 3.8 cm away from our planet every year. It is estimated that it will continue to do so for around 50 billion years. By the time that happens, the Moon will be taking around 47 days to orbit the Earth instead of the current 27.3 days.


2. The Moon has only been walked on by 12 people; all American males:The first man to set foot on the Moon in 1969 was Neil Armstrong on the Apollo 11 mission, while the last man to walk on the Moon in 1972 was Gene Cernan on the 
Apollo 17 mission. Since then the Moon has only be visited by unmanned vehicles.


3. The Moon has quakes:These are caused by the gravitational pull of the Earth. Lunar astronauts used seismographs on their visits to the Moon and found that small moonquakes occurred several kilometres beneath the surface, causing ruptures and cracks. Scientists think the Moon has a molten core, just like Earth.


4. The first spacecraft to reach the Moon was Luna 1 in 1959:This was a Soviet craft, which was launched from the USSR. It passed within 5995 km of the surface of the Moon before going into orbit around the Sun.


5. The Moon will be visited by a man in the near future:NASA plans to return astronauts to the moon to set up a permanent space station. Mankind may once again walk on the moon in 2020's if all goes according to plan.


6. In a survey conducted in 1988, 13% of those surveyed believed that the moon is made of cheese.


7. It is possible to have a month without a full moon. This occurs in February, but either January or March will have two full moons.


8. The Apollo missions brought back 2196 rock samples weighing 382 kg in total


9. The moon's diameter is about 1/4 the diameter of the Earth. About 49 moons would fit inside the Earth.


10. When Alan Sheppard was on the moon, he hit a golf ball and drove it 2,400 feet, nearly one-half a mile.

10 Facts about Voyager 1: 1. Voyager 1 Has Been Traveling for 35 Years Launched in 1977, September 5 will mark the 36th anniversary of Voyager 1's launch. That makes it one of the oldest pieces of space technology that is still in contact with Earth. 2. V1 Has Traversed Over 11 BILLION Miles To put this number in perspective, 11 billion miles is the equivalent of circling the Earth 440,000 times. And yet, in terms of light-years, the unit to measure space that is marked by how far light can travel in a year, V1 hasn't even left the neighbourhood. It will take 40,000 years for V1 to reach only two light-years distance from the sun. As large as 11 billion is, space is infinitely bigger. 3. V1 is Traveling At 39,000 mph This speed makes it the fastest space technology we have right now. Even spacecraft that have been launched years later with better technology is slower than V1. 4. It Was Originally Only Supposed to Survey Jupiter The original intention of V1 a

By 1942, the world had its first nuclear reactor. 4. Today, 104 nuclear plants supply about 2 0% of the United State’s electricity. The oldest plants have been operating since before 1979. 5. Contaminated food was still sold in the Ukraine after the Chernobyl accident. One worker described the conditions after the accident: “Contaminated meat would come from the factory. The internal organs of the cattle would be black and rotten, but still, the meat was sold." 6. Currently, nuclear waste in the United States is stored in cooling pools of water and in dry storage casks at nu
