Satellite competition

In the screening hall of the Aerospace Technology Training Center, 100 many students who have participated in the aviation summer camp are watching the movie Satellite Contest with great interest.

On the big screen, a huge rocket soared into the sky, with a flaming flame at its tail. Ten seconds later, the rocket rising vertically began to turn (ancient), and Wan (Wan) flew in the sky like a white dragon. About ten minutes later, the satellite left the rocket and went around the earth in a certain orbit.

Accompanied by this spectacular picture, came the sweet voice of the commentator's aunt: "Today, with the rapid development of science and technology, people have created many satellites with their diligence and wisdom, sent them into space with rockets, and circled the earth with the moon. Since 1957, the first Soviet artificial satellite was launched into the sky, human beings have successfully launched many satellites. According to different uses, artificial satellites can be divided into reconnaissance satellites, meteorological satellites, navigation satellites, communication satellites, resource satellites and rescue satellites ... They show their talents in space and compete to make contributions to mankind. "

The satellite competition has begun. The first thing that appears on the screen is a reconnaissance satellite with wings, which is shaped like a Dapeng (péng). It raised its camera and searched for military targets warily, shooting planes and submarines for a while and tanks and cannons hidden in the Woods for a while. It proudly said: "I can see soldiers walking in the barracks and people resting in the shade;" From the wheel tracks of cars and the hoofprint of war horses, we can also calculate the transfer of troops and the position of headquarters. "

In a flash, the clouds above the earth fluctuated and the meteorological satellites flapped their wings and flew slowly. It took out an infrared camera, took one photo after another for the earth, and encoded the cloud image and sent it to the earth quickly. It also sends out an emergency signal in time to warn a certain place (mǒu) that a typhoon or hurricane is about to happen, so that ships at sea can quickly enter the port. Meteorological satellite solemnly declared: "As long as I exist, people can reduce the losses caused by storms and floods."

The third appearance is the navigation satellite. It is like a palace lantern hanging in the sky, swinging back and forth rhythmically, and constantly giving out a silvery cry: "I am here, I am here ..."). Submarines and planes in the air hear its cry and sail to their destinations accurately according to the route it guides.

The fourth appearance is the communication satellite. It is covered with solar cells and has a trumpet-shaped antenna device on its head, which runs synchronously with the earth at an altitude of 36,000 meters. It is very sensitive to accurately transmit a large amount of information from telegraph, telephone and television on the ground. The communication satellite said confidently, "As long as I exist and take care of all the people on the earth, I can communicate and watch TV."

The fifth appearance is the resource satellite. With a big belly, it is equipped with a spectral camera, an infrared camera, a microwave radiometer and a test radar. It keeps taking pictures of the land and the sea on the earth, sorts out all kinds of information obtained, and then distributes it to all users on the earth. People use this information to draw maps, survey mineral deposits, catch fish and shrimp and protect the environment ... so it proudly declares: "I am creating great wealth for mankind every day."

Later, various satellites appeared on the screen one after another. Their shapes are different, some are spherical, some are cuboids, some are cylinders, and some are polygonal prisms ... It's really dazzling (Lí ná n ɡ) and dazzling (xiá).

Aunt, the commentator, said excitedly: "The satellite is difficult to distinguish. In today's wave of scientific and technological revolution, they all showed their magical powers and made great contributions to mankind! "
