How were the scientists able to study the moon?
Without a telescope, you can look up and tell that the moon has creators and what appears to be a white surface. Scientists use powerful telescopes to discover a bit more. For instance, NASA’s Lunar Impact Monitoring telescope studies lunar craters that large meteoroids create.
How did scientists explore the moon in the past?
Humans first landed on the Moon on July 20, 1969. Moon rock samples were brought back to Earth by three Luna missions (Luna 16, 20, and 24) and the Apollo missions 11 through 17 (except Apollo 13, which aborted its planned lunar landing).
Who is the last person to walk on the moon?
commander Eugene Cernan
He is 84. Apollo 17 mission commander Eugene Cernan holds the lower corner of the U.S. flag during the mission’s first moonwalk on Dec. 12, 1972. Cernan, the last man on the moon, traced his only child’s initials in the dust before climbing the ladder of the lunar module the last time.
How do scientist describe the moon’s surface?
The surface of the moon The moon’s surface is covered with dead volcanoes, impact craters, and lava flows, some visible to the unaided stargazer. Early scientists thought the dark stretches of the moon might be oceans, and so named such features mare, which is Latin for “seas” (maria when there are more than one).
How do scientists learn about the moon and the other planets?
Use telescopes on the ground or in space to make observations of distant planets, moons, etc.. Carry out experimental work in laboratories or in at different sites on the Earth which replicate different planetary environments.
How was observing the moon been important to science?
In just eight years, we had gone from zero human spaceflight capability to landing men on the surface of the moon. From these missions, scientists developed a new view of the origin and evolution of the planets and of life on Earth. Their visual observations added to the burgeoning knowledge of lunar geology.
What is moon and its characteristics?
A moon is a large body or mass or material that orbits around a planet. Characteristics of our Moon include its size of only about 1/4 the diameter of the Earth, while its gravity affects the Earth’s tides. The Moon looks bright at night because of sunlight that is reflected off its surface.
What are the characteristics of the Moon?
Moon
| Moon | approximate ratio (Moon to Earth) | |
|---|---|---|
| mean density | 3.34 g/cm3 | 1:1.7 |
| mean surface gravity | 162 cm/sec2 | 1:6 |
| escape velocity | 2.38 km/sec | 1:5 |
| mean surface temperature | day, 380 K (224 °F, 107 °C); night, 120 K (−244 °F, −153 °C) | — |
How do scientists know about the planets?
When astronomers look at an object’s spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy. This spread-out light is called a spectrum.
What can we learn from studying the Moon?
Some scientists have suggested that microorganisms could have existed on the Moon, possibly carried there by meteorites from Earth. Others have also proposed combing through lunar soil for elements, including ancient nitrogen or oxygen, from Earth, which could fill in gaps in knowledge about things like the development of Earth’s atmosphere.
What did the astronauts find on the Moon?
In all, astronauts collected 22 kilograms of material, including 50 rocks, samples of the fine-grained lunar “soil,” and two core tubes that included material from up to 13 centimeters below the Moon’s surface. These samples contain no water and provide no evidence for living organisms at any time in the Moon’s history.
Who was the first person to set foot on the Moon?
1969: Neil Armstrong was the first human to set foot on the surface of the Moon. He was also the first astronaut to become an educator. (Apollo 11) 1983: Sally Ride was America’s first female astronaut to fly on the Space Shuttle. (STS-7)
Who was the first American to go to the Moon?
