4月20日19时41分,搭载着天舟一号货运飞船的长征七号遥二运载火箭在我国文昌航天发射场点火发射,约596秒后,飞船与火箭成功分离,进入预定轨道,发射取得圆满成功。这是我国载人航天工程“三步走”发展战略第二步的收官之作,标志着我国即将开启空间站时代。从项目立项到产品运抵海南文昌发射场,过去6年间,天舟一号“隐姓埋名”苦练内功,经历了上千小时测试验证,经受了上百次大型试验考核,百炼成钢。
At 1941 on 20 April, the Long March No.7 Launch Vehicle of the Long March carrying the spacecraft No. 1 was fired at the launch site of Wenchang Space Station in China. After about 596 seconds, the spacecraft and the rocket successfully separated and entered the scheduled orbit, launching A complete success. This is the final conclusion of the second step of China’s manned space project and the “three steps” development strategy, marking the moment that China is about to open the space station. Over the past six years, Tianzhou One, an “incognito” masterpiece, has experienced thousands of hours of test and verification and has undergone hundreds of large-scale test tests to make it 100% refined into steel.
