Isro wants Chandrayaan-2 lander to orbit moon first

印度空间研究组织希望“月船2号”着陆器先实现绕月飞行

BENGALURU: Isro’s Chandrayaan-2 will now involve the lander going around the moon, taking a close look at the lunar surface, before descending on the dusty terrain for a battery of tests. The earlier plan was to make a direct landing after the lander carrying a rover separates from the orbiter.

班加罗尔：印度空间研究组织(ISRO)的月船2号现在将涉及着陆器绕月飞行，近距离观察月球表面，然后着陆并进行一系列测试。早先的计划是，在运载月球车的着陆器与轨道飞行器分离后直接着陆。

The change in plan, made at the fourth technical review meeting on June 19, entailed major changes to the lander hardware, including addition of a fifth liquid engine and a new leg configuration. This has resulted in further delay of the mission that missed three deadlines.

在6月19日第四次技术审核会议上，对原先的计划做出改变，涉及对着陆器硬件进行重大改变，包括增加第五部液体发动机和新支架配置。这导致发射任务的进一步推迟，而且已经错过了三次发射期限。

The team hasn’t decided how many times the lander should orbit before landing, but they know the orbit will be elliptical, with the farthest point at 100km and the nearest at 30km. This changed the mission configuration and caused the delay. As per the earlier plan, the lander was to separate from the orbiter at 100km and descend vertically up to 18km from the moon’s surface.

该组织尚未决定在着陆前着陆器应该绕轨道飞行几周，但他们知道轨道是椭圆形的，最远距离是100公里，最近距离是30公里。这改变了任务配置，并导致发射延迟。按照早先的计划，着陆器将在100公里处与轨道飞行器分离，垂直下降至距月球表面18公里处。

From there, the orientation would change, making the lander go slightly horizontal for about 8.5km and then make a soft landing, a senior member of the Chandrayaan-2 team said. “The earlier plan gave the lander little time to assess the tough terrain it has to touch as it slows from 6,000kmph to near zero to make a soft landing. The new plan allows the lander a better assessment,” said a senior scientist.

“月船2号”研究小组的一名高级成员称，从那里开始，着陆器的方向将发生变化，使着陆器略微水平移动约8.5公里，然后实现软着陆。早些时候的计划让着陆器几乎没有时间来评估它必须接触的恶劣地形，由于它的速度从6000公里/小时降至接近零，以实现软着陆。新计划允许着陆器进行更好的评估。

The lander will use its micro star sensors to read its own velocity and deploy its four reaction wheels for the landing.Isro wants Chandrayaan-2 lander to orbit moon first

着陆器将使用它的微星传感器来读取自己的速度，并为着陆部署四个反作用轮。ISRO希望“月船2号”的着陆器能先实现绕月飞行。

The best part about coming here to read the comments are from the ones who hate India. These are mooslees, Congress and mamta backers, christians, especially the newly converted christians and the angry ones who cannot make money from corruption anymore These people are the ones who want to see India fail at every step.

最有意思的是看那些讨厌印度的人发布的评论。这些人希望看到印度每走一步都以失败告终。

Congratulations to Yug Purush Modi Ji and BJP for funding these projects. Nowadays we are seeing almost every alternate days ISRO/Science/Technologies news. Muslim Party Congress wasted tax-payers money in distributing freebies, reservation to Muslims. Free Laptops, Free Cycle, Rs 30,000 were distributed to Muslims by Congress ally Namaajwadi Party in Uttar Pradesh. Rs 5 Lakh to every Muslims as free loan in Karnataka. Islamic Congress broke India''s economic backbone.

祝贺莫迪和人民党，他们为这些项目提供了资金。现在我们几乎每隔一天就会看到ISRO/科学/技术方面的新闻。msl国大党给msl分发免费赠品，预留名额，这浪费了纳税人的钱。在北方邦，国大党的盟友Namaajwadi 党向msl发放了免费笔记本电脑、免费自行车以及3万卢比。在卡纳塔克邦，给每个msl提供50万卢的免费贷款。ysl国大党摧毁了印度的经济支柱。

we should upgrade our technology by reading the vedas and old sanskrit texts. we had all this technology during mahabharat times.

我们应该通过阅读《吠陀经》和古老的梵语文本来升级我们的技术。我们在摩诃婆罗多时代就有了这些技术。

Sudarsan

Very prudent move. Circular path allows us complete views, and decide on the most appropriate place for landing. Also this gradual landing would allow less damage and landing gear.

非常谨慎的行动。圆形轨迹允许我们看到完整的视图，并决定最适合降落的地方。此外，这种逐渐着陆也会减少对起落架的损坏。

When will India put man on the moon.

印度什么时候能把人送上月球?

Great job ISRO! Its very refreshing to see the best of Indian minds striving to make the Mission Chandrayan 2 a success by leaving nothing to chance. Proud of ISRO - all the best for this well as all future space missions.

ISRO，做得好 !看到最优秀的印度人致力于实现月船 2号任务的圆满成功，真是令人振奋。为ISRO感到骄傲，祝未来所有太空任务一切顺利。

It is best religion and politics are kept out of this discussion, and many others .

在讨论这个问题或其它问题时，最好把宗教和政治排除在外。

isro could have done better to save 30 lives in Kerala floods by forcing the water bodies Dept with perfect data's to timely vent waters.

ISRO本可以更好地拯救喀拉拉邦洪水中丧生的30条生命，及时为水利部门提供准确数据来泄洪。

Is that a news? I dare anyone to land straight on moon without orbit. Intelligence of T0l is worst than 5 yr old.

这算新闻吗?我敢打赌，任何人都可以在没有绕月的情况下直接在月球上着陆。印度时报的智商比5岁的孩子还低。

Makes me wonder y, v wish to go down there when predators have found nothing. Y waste our money.

我不禁在想捕食者在那什么也没发现，你们还去那干吗？你们这是浪费我们纳税人的钱。

Any chance that we can put our own Pappu on the moon with his dynasty money flag converting the moon to Pappustan.

如果有机会，我们可以把拉胡尔送到月球上。

Paresh Patel

Don''t understand why waste poor taxpayers'' money just land a probe where live people had landed decades ago.

我不明白为什么要浪费纳税人的钱，仅仅是为了往几十年前别人就登陆过的地方送一个探测器。

Slumdogs dream of setting up slums on moon where can lynch and gang rape each other.

贫民窟的人梦想在月球上建立贫民窟，在那里可以实施私刑和轮奸。

Achievements of these sorts requires years and years of planning. Due respect should be given to the present and previous govt. Everything good that is being done in Country is Modi''s achievement and all bad things are fallout of congress rule

这些成就需要多年的计划。应该对现任和前任政府给予应有的尊重。一切好事都是莫迪的成就，所有坏事都是国大党执政的结果
