China’s “Question for Heaven” spacecraft has reached the orbit of this red planet, and it will launch one in May or June. Wanderer Explore its surface. Therefore, the Asian giant became the sixth space power to reach Mars after Russia, the United States, Europe, India and the United Arab Emirates yesterday.
On the second day of the Arab probe “Hope” inserted into orbit on Mars, the Chinese spacecraft also succeeded. Tianwen-1, Confirmed National Space Administration (CNSA) and China’s official news agency Xinhua News Agency.
After a journey of nearly seven months from the earth, the powerful 3000N engine of Astro One 12:52 hours (Spain time) began to slow down.
After a quarter of an hour, the spacecraft had slowed down enough to be captured by the gravity of Mars and entered Elliptical orbit Around the red planet, it will maintain an appointment with the red planet 400 km In the closest position.
Tianwen-1, which means “Ask heaven‘Written for a poem Qu Yuan (About 340-278 BC), it takes about 10 earth days to complete its orbit.
This event marks the completion of China’s current key step Mars Exploration Project, Designed to maintain Orbiter Around him, another one will be launched in three or four months.”Lander“From this in turn, Wanderer Or explore tools.
After entering Mars orbit, the instruments on the orbiter, including cameras and various particle analyzers, will begin to work and study the planet.
Since the launch of a Long March rocket launched from Wenchang Space Center (China) on July 23, 2020, on May 5, Five tons Weight, has been flying in space for 202 days.
Astro One has performed four orbit corrections and a deep-space maneuver, and it has also taken the first black and white photo of its approach to Mars.Flew 475 million kilometers It reached the orbit of the red planet 192 million kilometers from the earth.
One Radio telescope Can be controlled by a 70-meter-diameter antenna located near a Chinese city Tianjin, Is a key facility for receiving scientific data sent by the mission. The one-way communication delay is about 10.7 minutes.
Landing in May or June
Now, the spacecraft will perform multiple orbit corrections to enter the temporary parking orbit on the red planet and study possible landing sites in preparation for its “landing” in May or June. Wanderer Nearby Utopia.
It is a large plain in the northern hemisphere, under which there are a large number of frozen water, This is a resource of scientific and strategic significance for future manned missions.
If a successful landing on Martian soil, the rover will descend-similar to another flight on the moon-at least to operate Martian 90 days (About three months on Earth).
The entire mission, including the orbiter, the “lander” and WandererResearchers will study aspects such as the geological structure of Mars, the distribution of ice water on its surface, the ionosphere and the climate of the red planet, without forgetting the technological leap that China will achieve in space exploration compared with its rival, the United States.
