How well do you know Earth's Moon? How did it form, rotation, its orbit? Get up close and familiar- 5 points
Moon
1/5 How did the Moon form? According to the information provided by NASA, the leading theory behind the formation of the Moon is that a Mars-sized object collided with Earth billions of years ago, and debris from this collision eventually formed the Moon. (NASA)

2/5 Moon's rotation: The time it takes for the Moon to rotate once on its axis is equal to the time it takes for the Moon to orbit once around Earth. This keeps the same side of the Moon facing towards Earth throughout the month. (NASA)

3/5 Moon orbit Earth: According to NASA, the Moon takes about one month to orbit Earth (27.3 days to complete a revolution, but 29.5 days to change from New Moon to New Moon). As the Moon completes each 27.3-day orbit around Earth, both Earth and the Moon are moving around the Sun. Because of this change in position, sunlight appears to hit the Moon at a slightly different angle on day 27 than it does on day zero ― even though the Moon itself has already traveled all the way around Earth. It takes a little more than two additional days for sunlight to hit the Moon in the same way it did on day zero. This is why it takes 29.5 days to get from new moon to new moon, even though it doesn’t take quite that long for the Moon itself to travel once around Earth. (NASA)

4/5 Does the Moon have gravity? What would happen if there was no Moon? The Moon does have gravity. Because the Moon has less mass than Earth, its gravitational pull is weaker (about one-sixth of Earth’s). On the Moon, you will be able to jump about six times as high as you can on Earth ― but you would still come back down, informs NASA. Also, If there would be no Moon, Earth would be a very different world. The Moon’s gravity keeps our planet from wobbling on its axis too much, which helps to stabilize our climate. The Moon also plays an important role in creating tides in Earth’s oceans. (NASA)

5/5 Who Has Walked on the Moon? Neil Armstrong and Edwin "Buzz" Aldrin were the first of 12 human beings to walk on the Moon. Four of America's moonwalkers are still alive: Aldrin (Apollo 11), David Scott (Apollo 15), Charles Duke (Apollo 16), and Harrison Schmitt (Apollo 17). In all, 24 American astronauts made the trip from Earth to the Moon between 1968 and 1972. Three astronauts made the journey from Earth to the Moon twice: James Lovell (Apollo 8 and Apollo 13), John Young (Apollo 10 and Apollo 16), and Gene Cernan (Apollo 10 and Apollo 17). (NASA)

NASA scientist answers the most asked question “Is there water on the surface of the Moon?” (NASA)

Is there water on the surface of the Moon? This question ignites excitement as it opens up so many possibilities for the human species out there in near space. To answer NASA Moon expert, Casey Honniball answered all the queries. You will be glad to know that the answer is “Yes!” But it is not like we found the presence of water on Earth. Surprisingly, water is available all over the surface of the Moon, but it is available in the form of ice and not pools of liquid water. Some places on the Moon have more water than others.

Moon experts say that at the poles of the Moon are areas that never receive any sunlight, and so they're extremely cold, hence there could be a lot of ice inside them. Don't assume this ice as a pure form of water. The ice inside these regions can be mixed with the lunar soil, buried deep below the surface, or it could be just a sheet of ice. While surfaces on the Moon that do see sunlight experience extreme temperature changes of 300 Celsius, which makes it harder for water to survive. However, the water that remains on the surface is unlike any water available on Earth.

“..One day, future astronauts may be able to harvest this water and use it for drinkable water, breathable oxygen or rocket fuel to take us farther out into our solar system,” Honniball said. Harvesting this water will be critical in the future. Here's when the role of NASA's VIPER comes in.

About NASA's VIPER

NASA's VIPER, short for Volatiles Investigating Polar Exploration Rover, is a mobile robot traveling to the Moon's South Pole to search for ice and other potential resources of water to know where they came from. It could eventually be harvested to sustain human exploration on the Moon, Mars — and beyond. VIPER is also the first resource mapping mission on another celestial body. 

The VIPER robot is planned to deliver on the surface of the Moon in late 2024 under NASA's Commercial Lunar Payload Services (CLPS) program.
