Still waiting for the official confirmation
还在等待官方确认着陆成功的消息……
Congratulations!!
祝贺！！
Congratulations.
恭喜！
They beat the European Space Agency in this achievement, right? If so, WOW!
中国在这项成就上已经超越了欧洲航天局，没错吧？如果是这样，哇噢！
Muricans are going to be so crying hurt
米国人此时很受伤
You are succesful???? more sanctions in 3 , 2 , 1 ..... ? -_-
（模仿美国）什么？你居然搞成了？新一波制裁倒计时：3，2，1……？ -_-
Imagine their face when they see the Chinese space program is already completely sanctioned LOL
想象一下美帝人民脸上的表情——当他们得知对中国人的航天项目他们早已经“裁无可裁”之后——哈哈哈
A complete success of all obxtive is what I am hoping for. The rover has to able to roam and conduct experiment like the Perseverance or Curiosity
我希望看到的是所有预定项目都取得圆满成功。（祝融）火星车必须能够实现在火星表面漫游，并进行和（美国）毅力号或好奇号同样的实验操作。
Indians, specifically jai hinds won't be able to gulp it down their throats that China landed on Mars, they kept bragging about themselves as how they reached Mars first before China.
It would be hard pill to digest for them.
印度人，尤其是那些印度教徒，对中国成功登陆火星的消息想必是难以接受的。他们不断吹嘘自己曾如何如何早中国一步率先抵达火星。
对他们来说，这颗药丸实在太过苦涩。

I plotted the landing site for Zhurong. The line is the distance between the reported landing coordinates (top left) to the planned landing site (bottom right, which would be the centre of their landing ellipse).
Landing was about 39.04km to the WNW.
Note that the reported coordinates are only within 0.1 degrees, which is represented by this circle.
Would sure love to see that crater in more detail! But it's about 3.15km to the South.
我大致画了一下祝融号的着陆点，下图中的黄色线段，是根据报告标出的实际着陆点（左上方）到计划着陆点（右下，也就是他们规划的椭圆着陆区域的中心位置）的连线。
可以看到，着陆点向西北偏西方向偏离了大约39.04公里。
注意，根据中方报告的着陆点经纬度误差为0.1度，也就是图中圆圈范围。当然，真的很想看看那个大陨石坑里的详细情况！不过它位于（圆心）南面大约3.15公里（即正好着陆在里面的几率不大）。

How close is it to Viking 2?
这里距离（美国的）维京2号着陆器有多远？
原创翻译：龙腾网 http://www.ltaaa.cn 转载请注明出处
Pretty far, over 22 degrees latitude and 25 degrees longitude.
挺远的，维度差了22度，经度差了25度。
So it could have landed in the crater?
也就是说它还是有可能是降落在那个陨石坑的？
Theoretically
理论上是的

Not surprised at all, great to hear nonetheless.
丝毫不感到惊讶。不过听到成功着陆的消息无论如何都很棒。
It is surprising. China managed to successfully do the entire orbiter + lander + rover combo on Mars on the very first go with all systems being totally indigenous, new, and 100% untested and unproven ... until now.
I was expecting the lander part to be a failure and that wouldn't even be particularly bad. There are only four space agencies capable of putting such payloads into Mars orbit - China, US, Roscosmos, and ESA. To say nothing on landing which has only been done now by two nations. Great to hear for sure but definitely surprising.
应该说还是相当令人惊讶的。中国能在其第一次火星计划就成功完成轨道绕行+着陆+火星漫游这一系列任务，且整套系统使用的都是完全自主研制的、全新的、100%从未在现实航天任务中被测试被验证的技术——当然现在都验证了。
我原本的猜想是，着陆器这一块很可能会失败——即便那样其实也并不特别糟糕。至今为止，地球上也不过只有四个航天机构有能力将这种有效载荷送入火星轨道——中国、美国、俄罗斯航天局和欧洲航天局。没错，听到成功的消息很棒；但绝对更应该感到惊讶。
The rover part is still waiting to be done.
火星车这一块还尚待开展。
I know, working or not, I'm impressed by the lander which is the absolute hardest part. The rover is the whole point of the mission but technically much easier than getting the landing right.
我知道，但火星车能否正常工作还在其次，着陆绝对是最难的部分，我对此也最为印象深刻。火星车虽然是整个项目的重头戏，但从纯技术角度上讲，就要比准确着陆容易太多了。
So far China is the only nation to do it on her first attempt. That's something those meanly mouthed writers can't take away.
到目前为止，中国是唯一一个首次尝试（火星着陆）即成功的国家。这就让如今那些卑鄙拙劣、张嘴就来的“写手”们无论如何接受不了啦。
First off, congratulations to China. That's damned awesome. I really want to see the pictures and video from the surface.
I don't think that is correct. The US first attempts were the Viking landing. They were both successful.
首先，恭喜中国，真的太棒了。我现在一心期待着他们发布的火星表面照片和视频。
其次，我想楼上说的不准确。美国的第一次（环绕+着陆）尝试即维京-1号（又名海盗-1）计划，也是（环绕+着陆）都成功的。
It will take several days for the solar panels to gain enough solar energy to power up the rover. If, God forbid, a dust storm obscures the sun during this process, it can take even longer.
还需要好几天时间才能通过太阳能电池板为火星车准备好足够的动力。而万一（拜托千万不要）突发一场火星沙尘暴遮蔽了阳光，那就可能还得要更长时间。
“This landing reinforces the point that we don’t own space any more,” King told
Oops! Did he just let his inner thoughts slip for a moment here?
美国参议员：“中国登陆火星提醒我们：‘太空不再是我们美国的了’”
参议员金恩说，“这次成功登陆无疑是一个强烈信号，即我们‘不再独自拥有太空’”
哎呀！他是不是一不小心把自己的内心活动给说出来啦？
Nah...rather more reasons for congress to support the US Space Force against the "big bad China".
不是……他是为了给国会更多理由支持美国“太空军”去对付“中国大坏蛋”。
He's talking to those inside the Beltway idiots who think that Beidou is fake news (yes, there are still plenty of people like that in DC).
他是在向美国那些政治精英圈里的白痴，那群仍然以为北斗系统是“假消息”的家伙喊话（没错，在华盛顿仍有很多这样的人）。
There are some very deeply stupid people inside the Beltway. They are high unlikely to ever get the levers of power, but as shown by Trump, it is not completely impossible.
美国政治圈里有一部分人真的非常愚蠢。（原以为）这类人不太可能把持权柄，然而特朗普的出现表明，这也并非绝无可能。

SANCTION China space program!
But Sir it is already sanctioned!!
No! Sanction it moree
“制裁中国航天项目！”
“可是，长官，已经制裁了啊！！”
“我不管！给我叠加再制裁！”
how fragile the white anglo is to be so threatened by scientific discovery.
昂撒人是有多脆弱，才会把一项科学探索计划当成如此大的威胁
It's the crowd that hates China combined with the crowd that considers itself exceptional and "superior" so need to find excuses and reasons for everything that seems to put those assumptions into question.
However this vocal stuff is actually good as the balanced and reasonable part of western populations can see the blatant hate and dismissive attitudes and recognise that China and Chinese people indeed are treated and considered quite unfairly from the streets to the highest echelons of politics. It wakes some people up...
Oh and of course paid/unpaid Indian trolls that are everywhere on the English speaking internet whenever the word "China" comes up. That is their main hustle next to demanding explicit photos from western women.
只是那么一群仇中的人，再加上一些自命不凡总以为自己“高人一等”的家伙，当他们那些虚幻的假设遭到质疑时，就会急不可耐地寻找一切借口和理由。
然而，这一类声音实际上有它的好处——它让那些心态平衡且理性的西方人，可以看清这种公然的仇恨和歧视，并认识到中国和中国人的确是遭受到了相当程度的、针对性的不公平对待——从街头巷尾的底层，直到政治权力核心的最高层级。这至少能唤醒其中的一些人……
哦，当然了，在英语世界的互联网上，只要一出现“中国”这个词就会引来一群有偿或无偿的印度网军。此事另当别论——毕竟这就是他们的主要工作——而其次要任务则是向网上的西方女性索要露骨照片。
Well India will always claim they got to Mars orbit before any other Asian country and there will be the backhanded jibes in the media about how Russia has never managed to successfully soft land something on Mars! When the pictures from the Chinese rover do get released, we'll get the 'China Threat, need to invest more in space" stories.
On that point there's precious little news about the UAE's mars mission launched on a Japanese H-2 rocket that arrived in orbit around mars a day before the Tianwen either.
Just lots about that NASA mars helicopter with the software control bug
好吧 ，印度会一如既往地声称自己才是亚洲国家中第一个抵达火星轨道的；他们的媒体也会一如既往地嘲讽俄罗斯从未成功在火星实施软着陆！而当中国火星车拍摄的照片发布时，我们或许又会听到“来自中国的威胁！我们需要更多太空投资！”一类故事。
还有就是，有关阿联酋使用日本H-2火箭发射的火星探测器任务，似乎至今没有任何重要的消息传回来？这个探测器应该是在天问一号之前一天抵达火星轨道的吧。
最近只读到很多关于NASA的火星直升机控制软件bug频出的新闻了。
Eh, I know that everyone is happy about this but the reality is, it was done with help from Argentina and France, the latter is a NATO member. The idea of complete autarky for China or any single country is unrealistic. China should have learned this from the Qing dynasty. Even the US has to pay attention to how it is viewed abroad and the opinions of its allies.
呃，我知道大家都对这个消息感到高兴，但还是要实事求是，中国这次任务的成功，还有阿根廷及法国的参与和帮助，注意后者还是北约成员国。中国或者说任何一个国家，想要百分之百不借助其它国家完全靠自己（进行太空探索）是绝不现实的。中国应该不会忘记清朝的历史教训。即便是美国，也必须要关注外国对它的看法，以及盟友们的意见。
America couldn't stop a proud and independent France from collaborating with AmeriKKKa's sworn enemy, shows the limits of American power. Argentina was actually the most important partner, since they provide a tracking station which saves China from deployment of one ship in the yuanwang fleet.
美国甚至无法阻止一个自豪而独立的法国与美国的死对头合作，这充分显示了美国实力的局限性。事实上，阿根廷才是这次任务最重要的外国合作伙伴，因为他们提供了一个跟踪观测站，否则中国将不得不把一艘远望号部署过去。

and the vitality of YOUTH too.
而且还是如此朝气蓬勃的青年才俊。
I`m in love, i want to marry her right now <3 ;)
This is one of the most exciting forum section ever, one huge respect and congrats for China for all those astonishing acomplishments, great work, im looking forward for more amazing missions and advance in Chinese space exploration. Keep great work up, cheers!!
ps: im serious to marry this goddess!!
我爱她！我现在就想和她结婚 <3 ;)
说真的，这个论坛板块实在是（互联网上）少有的激动人心之处！我要对中国所有这些惊人的成就、伟大的工作致以崇高的敬意和祝福！并期待更多令人赞叹的航天任务、更加深广的太空探索。继续努力！欢呼！！
附：想和那位女神结婚，我也是说真的！！
Official response regarding photos from Martian surface:
Many people are asking how come there still aren't any photos from Zhurong yet. It's been three days since landing and still no photo back, is there a problem blablabla. Don't be so hasty, we will analyse the reason behind lack of photo.
On the day of the landing the lander will be talking to earth via direct communication. In this mode the bandwidth is 16bps, so 2 bytes per second. At this speed the comms is only sufficient for judging spacecraft status and not enough for transmission of photos. A 100KB uncompressed low resolution photo will take 14 hours to transfer at this rate, and this is not taking into account Zhurong's own bandwidth requirements. 3 Sols after landing (Monday night, 17/05/2021) the rover will attempt first UHF communication with Tianwen-1 in orbit, and each transmission attempt will last 8-10 minutes. Once established each day it will support 20Mbit (2.5MB) of data. Then after this every 3 days the rover will attempt to establish X band communication, this channel will support 50Mbit (6.25MB) of data per connection. Thus tonight (night of 17/05/2021) first data pack of 2.5MB should arrive, hopefully this 2.5MB data pack will have some post landing photos. If not worry not, more data will come in the coming days, sooner or later you will see first photo from the Martian surface.
People probably aren't going to be impressed with low resolution photos and trying to cram a high resolution photo in the 2.5mb data isn't really a good use of that bandwidth since there are lots of other things needing to be sent back to earth I'm sure.
（中国）官方关于那些询问火星表面照片的回复来了：
“最近很多人问为什么祝融号到现在依然没有图片回传？着陆两三天了都还没回传是不是有问题等等等，诶，别着急，下面就分析一下为什么直到现在都没有照片的原因：
“落火当天使用的是自主的直接对地通讯方式，这个对地通讯模式的传输速率仅仅为16bps，也就是一秒传输2个字节，在这种带宽下，仅仅只能判断探测器状态，极其难以实现图片回传，如果一张100KB的低清图片没有经过压缩的话，使用这个小水管回传需要大概14小时左右，这还是不考虑祝融号本身测控的所占用的带宽，但是，在三个火星日之后（也就是5月17号晚上）火星车会首次和轨道上的天问一号尝试建立UHF通讯链路，每次持续8~10分钟，建立链路成功以后，每天就能够回传20Mbit（2.5MB）的数据，所以，如果一切都顺利，今天晚上可能拿到祝融号的第一批大小约为2.5MB的数据，就让我们期待这2.5MB小小的数据包里面有没有着陆后的照片吧。如果没有也不要灰心，再等几天，数据会陆续的传回来，相信早晚能看到我国第一张从火星表面发来的照片的！”
China releases photos from Tianwen-1 Mars probe after landing
Ramp deployed cleanly, looks like the lander picked a very flat spot indeed.
中国公布“天问一号”火星探测器着陆后照片：
滑降斜面布置得非常干净，还有看起来着陆器确实选择了一个相当平坦的着陆点。
The key step! Data can be transmitted back!
But there are still important tasks to be done. At present, the Mars rover is preparing to leave the landing platform. It will choose a plane to drive on the surface of Mars and begin to patrol and explore.
非常关键的一步！证明数据可以回传！
但后面仍有重要任务等着完成。目前，（祝融）火星车正准备脱离着陆平台。它将选择一个平坦区域，开始火星漫游和探索之旅！
Beautiful. Can’t wait till it rolls off the ramp.
漂亮！真等不及想看到它从那斜坡上出发了！
The probe also sent back a video taken by a camera on the orbiter, showing how the lander and the rover separated from the orbiter during landing.
天问一号还同时发回了一段从轨道飞行器（环绕器）上的摄像头拍摄的视频，显示的是着陆器和巡视器在开始登陆任务时是如何与环绕器分离的。
Again, China is doing this for the first time and it's already showing all the happenings in Mar's orbit, in this case, the separation of the Zhurong capsule from the Tianwen-1 orbiter. I don't recall NASA showing any video footage of its spacecraft's action in Mars' orbit other than CGI.
再一次，中国哪怕是在其首次尝试时，就在努力向世人展示火星轨道上发生的一切，这里就包括祝融号与天问一号轨道飞行器分离的情景。在我的印象里，NASA除了CG动画外，还从未展示过其航天器在火星轨道上运行的任何视频片段。
Despite the success of Tianwen-1, the Chinese are lucid about the technological gap with the Americans. For example In the early stage of the development of the Mars program, research was carried out on Mars aircraft. The team carried out analysis of various models (including fixed wing and rotor) but concluded that due to Mars low atmospheric density, current domestic technology level is inadequate.
尽管天问一号取得了成功，但中国人自己也清醒地认识到他们与美国的技术差距。例如，他们在筹备火星任务的早期阶段，就对火星飞行器进行过论证。研究小组对各种飞行器模型（包括固定翼和旋翼）都做了分析，得出的结论是，由于火星大气密度过低，目前中国（在火星部署飞行器）的技术水平还不够。
To put things into context, this mission has a takeoff mass of 5,000kg, contains an orbiter, lander and rover, enters Mars orbit with the orbiter, and uses powered descent and obstacle avoidance during final. All this on China's first attempt at anything past the Moon. Not to mention the earlier trouble with Long March 5 between 2017 and 2019 putting the mission in doubt.
This has got to be one of the most insane interplanetary missions in decades if not ever, congratulations to CNSA and everyone involved for acing another major mission milestone! Now onwards to the surface and discovery!
总的来看，不论如何此次任务都是一次发射有效载荷达5吨，把一个轨道飞行器、一个着陆器外加一个巡视器，运送到火星轨道，最后采用反推火箭+避障机制实现着陆的一整套探火工程。而所有这一切都仅仅是中国航天对“走出地月系”的首次尝试！更别提在2017到2019年期间由于长征五号出状况而让整个项目遭受质疑的时刻（有多少困难）了。
这必将被铭记为过去数十年来最大胆/最疯狂的太空计划之一（如果不是有史以来的话）。祝贺中国国家航天局和所有参与其中的航天人，你们完成了又一个重大里程碑式任务！现在，朝着新的极限前进，继续去探索发现吧！
