my country has more than 600 application satellites in orbit: the farthest spacecraft is 400 million kilometers away from the earth
This represents the most complex and cutting-edge scientific and technological achievements in the aerospace field today, and is flying around the earth at the first cosmic speed of 7.9 kilometers per second.
400 million kilometers is the distance from Earth to Mars. On this planet, the Zhurong rover has traveled nearly 2,000 meters. my country’s first Mars exploration completed the three major goals of Mars orbiting, landing and inspection through one mission, creating the first time in the history of human spaceflight.
In the past ten years, the number of application satellites in orbit in my country has exceeded 600, and more than 2,000 aerospace technology achievements have served people’s livelihood.
In ten years, 11 astronauts entered space, the space rendezvous and docking shortened from 44 hours to 7 hours, and the astronaut residence time increased from 13 days to 6 months.
In the past ten years, my country has successfully completed the three-step strategy of “circling and falling back” for lunar exploration. At present, the Moon Rabbit No. 2 on the back of the moon has spent 45 months on the moon, traveling a total of 1,200 meters, becoming a human being on the lunar surface. The longest working lunar rover.
In the past ten years, from 400 kilometers to 400 million kilometers, this space coordinate, which is near one and one far away, records the continuous innovation of China’s aerospace industry.
