Earth's Satellite Moon PPT, Part 2: New Lesson Explanation

Human exploration of the moon

People observe the moon with their naked eyes and use stones, charcoal, etc. to record their observations.

In 1610, Italian scientist Galileo invented the astronomical telescope and observed the moon with an astronomical telescope for the first time.

In September 1959, scientists from the former Soviet Union used an unmanned lunar exploration vehicle to fly over the back of the moon and take pictures of it, allowing people to understand the full picture of the moon.

In July 1969, the American "Apollo 11" manned spacecraft sent humans to the moon for the first time. Astronaut Armstrong was the first to set foot on the moon, and humans successfully landed on the moon for the first time.

3. The volume of the moon is about 1/49 of the earth

4. The moon’s gravity is about 1/6 of the earth’s

Topographic features of the moon

There are two main types of terrain on the moon: maria and craters.

Moon Sea

The lunar maria is a basin made of solidified lava, a "sea" without a drop of water.

Many people believe that the lunar maria was formed when a small celestial body hit the moon, breaking the lunar crust and causing the lunar mantle to flow out. The basalt magma covered the lowlands and formed the lunar maria.

Yuelu

The moon itself does not emit light, it only reflects sunlight. We call the surface of the moon the lunar surface. The bright parts of the moon visible to the naked eye, commonly known as the lunar continent, are actually mountains and plateaus on the moon.

China’s aerospace development history

1: Breaking through the "satellite to the sky" barrier: China's medium and long-range missile technology has passed the barrier

On April 24, 1970, my country successfully launched the Dongfanghong-1 artificial earth satellite into space using its self-developed Long March-1 carrier rocket. The beautiful music "Dongfanghong" spread throughout the world, and countless Chinese people rushed to tell each other and cheered. .

2: Breaking through the "satellite recovery" barrier: the vanguard reconnaissance satellite monitors the United States, Japan and Taiwan

On November 26, 1975, my country successfully launched a returnable satellite using the "Long March 2" carrier rocket. The satellite returned to the ground as scheduled after operating in orbit for 3 days. China became the third country in the world to master satellite recovery technology.

Three: Breaking through the "one arrow, multiple stars" barrier: the split-guidance technology makes it difficult for the enemy to guard against it

On September 20, 1981, my country used a launch vehicle to simultaneously launch three satellites into orbit, making China the third country in the world to achieve multi-satellite technology with one rocket.
