中国首次火星探测任务“天问一号”探测器成功发射

2020年7月23日12时41分，在海南岛东北海岸文昌航天发射场，中国用长征五号遥四运载火箭成功发射首次火星探测任务（天问一号）探测器。飞行2000多秒后，成功将探测器送入预定轨道，开启火星探测之旅。美国宇航局局长Jim Bridenstine对中国此次火星探测的成功发射表示支持，他在在Twitter写道："今天的发射意味着，中国也正在加入火星国际科学探险家的行列，" 他还写道："天问一号，一路平安！"

A Chinese-made rocket took off from Hainan Island carrying the Tianwen-1 probe, the People’s Daily said on its Twitter account, on the initial leg of its seven-month journey to Earth’s neighbor, traveling 3 miles per second as the program tries to make China a space superpower. Last year, it became the first nation to land a probe on the far side of the moon. NASA Administrator Jim Bridenstine welcomed China’s mission.“With today’s launch, China is on its way to join the community of international scientific explorers at Mars,” he said in a message on Twitter. “Safe travels Tianwen-1!” he wrote.  source
