9月12日,苏联成功地发射了第二个宇宙火箭,准确地命中月球,这是一个振奋人心的好消息。大家知道,苏联在1957年10月4日发射了第一个人造地球卫星,以后又连续发射了两个;今年1月2日,苏联发射了第一个宇宙火箭,通过月球附近成为第一个人造太阳行星;如今发射的第二个宇宙火箭又成功地到达月球。真是一个胜利接着一个胜利。这次发射的宇宙火箭和上次相比较,无论从速度、重量、准确度等方面,都可以看出,苏联在火箭技术上又取得了巨大的新成就。首先,上次飞行速度是每秒11.2公里多一点,这次又超过了上次的速度;重量方面,这次最后一级去掉燃料是1,511公斤,比上次的重39公斤,仪器重390.2公斤,比第一次又重28.9公斤。上次的火箭在月球附近通过,离月球还约有6,000
On September 12, the Soviet Union successfully launched the second space rocket and accurately hit the moon. This is a very encouraging good news. As we all know, the Soviet Union launched its first man-made earth satellite on October 4, 1957, and fired two more consecutively. On January 2 this year, the Soviet Union launched its first space rocket and passed the vicinity of the moon as the first one Artificial sun planet; the second space rocket now launched successfully reached the moon again. Really a victory followed by a victory. Compared with the last time, the space rocket launched this time shows that the Soviet Union has made tremendous new achievements in rocket technology in terms of speed, weight and accuracy. First of all, the flight speed last time was a little more than 11.2 kilometers per second, this time exceeding the speed of last time. In terms of weight, the amount of fuel removed at this last stage was 1,511 kilograms, 39 kilograms more than the previous one and 390.2 kilograms , 28.9 kg heavier than the first one. The last rocket passed near the moon and about 6,000 from the moon
