CCTV News: Over the past decade, some key core technologies in my country have achieved breakthroughs, strategic emerging industries have developed and grown, and major achievements have been achieved in manned space flight and lunar and fire exploration.
400 kilometers, which is the distance from the earth to low-Earth orbit in space.
In this busy area, the most dazzling one is China Space Station . At this moment, 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.
In the past decade, 11 astronauts entered space, and the space rendezvous and docking was shortened from 44 hours to 7 hours, while the time for astronauts to stay increased from 13 days to 6 months.

Now, on the other side of the moon that we cannot see, " Yutu 2 " has spent 45 months, traveling more than 1,200 meters in total, becoming the lunar rover , which has been working the longest time on the moon.
.4 billion kilometers, which is the distance from the earth to Mars .
On this planet, Zhurong Mars rover has traveled nearly 2,000 meters. my country's first Mars exploration completed the three major goals of Mars orbiting, landing and patrol through a mission, creating the first in human space history.
In the past ten years, my country has used satellite in orbit and has served people's livelihood with more than 600 aerospace technology achievements.
In the past ten years, from 400 kilometers to 400 million kilometers, this nearly and far space coordinate records the continuous innovation and leapfrog journey of China's aerospace .
