Cosmic Rhapsody PPT, Part 2: The second phase of the moon landing breakthrough

2: The second phase of the moon landing breakthrough

In the second phase of China's lunar exploration project, the "lunar lander" will softly land on the lunar surface. There is no atmosphere on the moon, so a parachute cannot be used to complete a soft landing. Therefore, a brake rocket must be used to decelerate. After reaching a safe landing speed, a soft landing is completed through a landing buffer device.

The second phase of the lunar exploration project will launch a "lunar lander" and a "lunar rover" that can patrol and inspect the lunar surface. The main functions of the lunar rover: carry detection instruments and provide normal working guarantees for the detection instruments, such as power supply, temperature control, measurement and control conditions, etc.; transmit scientific detection data back to the earth.

Cosmic Rhapsody PPT, the third part: Chang'e's return to the earth in the third issue

Three: Chang'e returns to the earth in the third period

In the third phase of China's lunar exploration project, the "Lunar Automatic Sample Return Detector" will automatically collect lunar samples on the lunar surface.

In the third phase of the lunar exploration project, the "lunar automatic sampling return probe" return capsule flew away from the moon and flew towards the earth.

The "Lunar Automatic Sample Return Probe" return capsule is on its way back to Earth

The Lunar Automatic Sample Return Probe's return capsule carries lunar samples and flies over the Earth

Cosmic Rhapsody PPT, Part 4: Why the Moon was Developed

Why develop the moon

First: The moon is rich in mineral resources.

Second: The development and utilization of new lunar energy has broad prospects.

Third: The special space environment on the lunar surface is an ideal place to establish astronomical observatories, research bases and develop special biological products and materials.

Fourth: As mankind’s only, large and stable “natural space station”, it is also an outpost and transfer station for mankind to explore the solar system and carry out deep space exploration.

Cosmic Rhapsody PPT, Part 5: Summary of the Chang'e Project

Summary of Chang'e Project

my country's lunar exploration plan, codenamed "Chang'e Project", began implementation in 2004. It is divided into three stages, which can be summarized in three words: "circling down and returning".

Orbiting: Chang'e-1 was launched in 2007 and orbited the moon for one year.

Fall: Launch a lunar probe to land on the moon before 2010.

Answer: Before 2020, the lunar landing robot will return to Earth after collecting some samples from the lunar surface.

Can you create your own blueprint for developing the moon? After class, students communicate and cooperate with each other to complete the task.

Search for aliens

1. Extensively receive and study various electromagnetic wave signals from space.

2. Actively transmit signals to space.

3. Launch the detector.

Cosmic Rhapsody PPT, Part Six: Conjectures about Aliens

Conjectures about aliens

1. Questions you want to explore: Are UFOs authentic or aliens?

2. Methods to solve problems: ask experts, search in the library, search online

3. Information to be collected: progress of the lunar exploration project, scientists’ plans to explore extraterrestrial organisms

4. Activities to be carried out: Portraits of Aliens in My Heart, Report on Latest Developments of Alien Creatures

Cosmic Rhapsody PPT, Part 7: Homework

after class homework

1. If you were the designer of Chang'e 5 or 6, how would you design it?

2. If you wrote or chatted with aliens, what would you say?
