Liquid-fueled carrier rocket
On June 25, the Long March 7 rocket was successfully launched in China’s Hainan province. The newest member of the Long March family was designed as a liquid-fueled carrier rocket, powered by *liquefied oxygen and *kerosene. Compared to earlier rockets, the Long March 7 is expected to be cleaner and stronger. Its fuels only produce carbon dioxide and water when they burn.
6月25日，长征七号运载火箭在海南文昌航天发射场点火升空。作为“长征家族”的新成员，长征七号是液体燃料运载火箭，采用了液氧煤油发动机等新技术。和此前的火箭相比，长征七号更清洁，动力也更强。在燃料燃烧时，只产生二氧化碳和水。
马上学：液体燃料运载火箭使用的是液体火箭发动机(liquid propellant rocket engine)，它采用液体燃料和氧化剂(oxidizing agent)作为能源产生推力。
