话题语境
Thousands of years ago,Chinese poet Qu Yuan wrote the poem Tianwen,meaning Quest for Heavenly Truth.He came up with a series of questions about the sky,stars,nature and the world around us.The poem showed his spirit of finding the truth.
Inspired(激励) by the great poet,China named its latest series of planetary exploration 1. missions (行星探测任务) after the poem in 2020.The first one in the series—a Mars exploration mission—has been named Tianwen 1,the China National Space Administration(CNSA) said on April 24th,2020, China’s Space Day.This shows China’s wish to explore the universe.
China has made great progress in space exploration.In 1970,China sent its first man-made earth 2. satellite (卫星),becoming the fifth country in the world to send a man-made satellite independently.Since 2003,China has carried out nine Shenzhou manned missions.China’s moon exploration missions—the Chang’e series—started in 2007.In December 2018, China became the first country to send the 3. probe (探测器) Chang’e 4 to the moon’s far side.
The Tianwen series follows the Shenzhou and Chang’e series and moves further into space.The first step was to send a Mars probe,which meant the start of China’s exploration of the red 4. planet (planet). The probe was planned to circle around,land on and explore Mars in one mission.It was the first to finish all of these tasks in one mission.The Long March 5 rocket sent the probe to Mars.
After this mission,China plans to visit Mars again in 2028,5. aiming to collect soil from the ground of the planet and bring it to Earth.Around 2030,China will explore Jupiter and several small planets.
