印度“月船2号”进入月球转移轨道

Chandrayaan-2 enters lunar trajectory for straight journey to Moon's orbit

“月船2号”进入月球转移轨道，将直奔月球轨道

NEW DELHI: At 2.21am on Wednesday, Chandrayaan-2 said goodbye to Earth and left the planet's orbit to enter a straight path towards Moon. The Indian space research organisation (Isro) successfully conducted the 'trans lunar injection (TLI) manoeuvre. During the TLI manoeuvre, the spacecraft's liquid engine was fired for about 1,203 seconds to make it enter the lunar trajectory after it had spent 22 days in Earth's elliptical orbit.

新德里：周三凌晨2点21分，“月船2号”告别地球，离开地球轨道，进入月球转移轨道。印度空间研究组织(Isro)成功地进行了变轨操作。在操作期间，探测器的液体发动机被点燃约1203秒，使其进入月球转移轨道，此前在地球椭圆轨道上运行了22天。

Explaining the lunar trajectory journey, Isro chairman K Sivan told TOI, "Chandrayaan-2 will take six days to travel in the lunar trajectory to reach Moon (lunar orbit) on August 20." The total distance from Earth to Moon is 3.84 lakh kilometre.

Isro主席K Sivan告诉印度时报：“月船2号将在月球转移轨道上运行6天，于8月20日到达月球(月球轨道)。”从地球到月球的总距离是384000公里。

To put Chandrayaan-2 in the lunar trajectory from perigee (the point in the orbit when the craft is nearest to Earth), Isro had first raised the elliptical orbit of the lunarcraft around Earth by conducting five manoeuvres. The fifth manoeuvre was conducted successfully on August 6 when the propulsion system was fired for a duration of 1,041 seconds, following which Isro had said all the lunarcraft's parameters were normal. Out of 3,850kg (launch) mass of Chandrayaan-2, 2.542kg is just the weight of fuel.

为了将“月船2号”从近地点(距离地球最近的点)送入月球转移轨道，Isro先进行了五次变轨操作，将“月船2号”的椭圆轨道提高。第五次变轨是在8月6日成功进行的，当时推进系统点火持续1041秒，随后Isro表示所有参数都正常。“月船2号”总重量为3550公斤(，其中燃料重量为2542公斤。

On entering Moon's sphere of influence, the onboard propulsion system of Chandrayaan-2 will be fired again to slow down the craft, which will enable it to be captured into a preliminary orbit around Moon.

进入月球范围后，“月船2号”的机载推进系统将再次点火，以减慢速度，这将使它能够进入月球的初步轨道。

Through a set of manoeuvres, the orbit of Chandrayaan-2 around Moon will be circularised at a height of 100 km from the lunar surface. Sivan said, "Like we had raised the Earth orbit of Chandrayaan-2 with the help of the propulsion system to take the craft away from Earth, we will use the propulsion system to lower the lunar orbit of Chandrayaan-2. We will do five to six manoeuvres to reduce its orbit." Thereafter, Lander 'Vikram', named after the father of Indian space programme Vikram Sarabhai, will separate from the orbiter and enter into a 100kmx30km orbit around Moon. Once the lander reaches 30km altitude on September 6, the final descent to the lunar surface will begin.

通过一系列的操作，“月船2号”围绕月球的轨道将在距月球表面100公里的高度。Sivan称:“就像我们在推进系统的帮助下提高了“月船2号”的地球轨道，把它带离地球一样，我们将使用推进系统来降低“月船2号”的月球轨道。我们将进行五到六次降低其轨道的变轨操作。”在此之后，以印度太空项目之父维克拉姆·萨拉巴伊命名的“维克拉姆”号着陆器将与轨道飞行器分离，进入100x30公里绕月轨道。一旦着陆器在9月6日达到30公里的高度，将最后一次降低高度以在月球表面着陆。

If the Chandrayaan-2 team, led by project director M Vanitha and mission director Ritu Karidhal, is able to land the lunarcraft successfully in the wee hours of September 7, India will become the fourth country in the world to land its spacecraft on Moon.

如果探测器能够在9月7日凌晨成功着陆，印度将成为全球第四个在月球上着陆探测器的国家。

It needed a visionary like NEHRU to SEE a need for SPACE RESEARCH way back in 50s and initiate a PLAN in this regard ! KUDOs to visionary leaders we had those days ! Today also OUR leaders are carrying on the same VISION ...

早在50年代，印度就需要像尼赫鲁这样有远见卓识的人，意识到探索太空的必要性，并发起太空计划!
