More about Planet Four Translations

Üdvözlünk a Planet Four oldalán! 欢迎光临第四行星!Willkommen bei Planet Vier! 歡迎光臨第四行星!

You might remember that Planet Four is available in traditional and simplified character Chinese, but did you know the site is also available  in German and Magyar(Hungarian)? We wanted to share a little bit more about some of the people who’ve helped make these translations possible.

Ning Ding helped verify the science content of the simplified Chinese character  translation. Here’s more about Ning in English and in simplified character Chinese:

Ning Ding is a Ph.D candidate of China University of Geosciences (Wuhan) major in structure geology.She is mainly interested in  the central uplifts of Martian impact craters and comparative planetology. She was a visiting student in HiRISE team in the US where she knew the Planet Four and participated in Chinese translation the website.

丁宁现在是中国地质大学(武汉)构造地质学专业博士生,研究兴趣主要为火星撞击坑中央隆起构造及比较行星学。曾作为访问学生在火星HiRISE项目组学习,并因此接触到Planet Four网站,继而参与Planet Four简体中文版的翻译工作。

Lukas Hackl helped translate Planet Four into German . Here’s more about Lukas in German and English:

My name is Lukas Hackl. I am from Austria and working for an IT company. I am interested in Astronomy, Photography, Motorcycle and other science. I like to be part of researches and help scientists around the world.

Mein Name ist Lukas Hackl. Ich komme aus Österreich und arbeite für eine IT-Firma. Ich interessiere mich für Astronomie, Fotografie, Motorrad und andere Wissenschaften. Es gefällt mir Teil von Forschungen zu sein und Wissenschaftlern auf der ganzen Welt helfen zu können.


Szatmáry László  helped translate Planet Four into Hungarian/Magyar . Here’s more about  László in Magyar and English:

So, I’m an Application Specialist in a Hungarian software company and a beginner amateur astronomer. I’m participated in numerous Zooniverse projects and I think it is a great way to help science and scientist in their works. I have only one bigger experience in translating, I was one of the Hungarian translators of I’m interested in sports, chess, stars and environment defense.

Alkalmazástechnikai szakember vagyok egy magyar szoftvervállalatnál illetve kezdő amatőrcsillagász. Több Zooniverse projektben is részt veszek, szerintem ez egy hatalmas lehetőség a tudomány és tudósok segítésére. Jelentősebb fordítói tapasztalatom eddig a magyarítása volt, itt egy voltam a többi fordító között. Érdekel a sport, a sakk, a csillagok és a környezetvédelem.

Planet Four Now Available in Simplified Character Chinese


欢 迎光临第四行 星!We’re pleased to announce that Planet Four is now available in simplified character Chinese. Thanks to the efforts of the Education and Public Outreach (EPO) Office and Zheng Meyer-Zhao at the Institute of Astronomy & Astrophysics, Academia Sinica (ASIAA) in Taiwan. Also a big thank you to Chris Snyder from the Zooniverse’s development team at Adler Planetarium for  all the technical help and to Ning Ding at the Lunar and Planetary Laboratory at the University of Arizona for help verifying the translation. Below is a note from  Zheng Meyer-Zhao and some info about the site both in simplified Character Chinese and in English:

Zheng Meyer-Zhao

I am a software engineer at ASIAA, born and raised in the north-east of China. It has been my pleasure to participate in the translating efforts the Planet Four website to simplified Chinese. During the Citizen Science workshop organized by Meg in March 2014 at ASIAA, I learned that many people worldwide are joining this great project in their spare time to help out scientists. However, there are not many people participating from China yet. The main reason of this is the availability of the information, as there was no Simplified Chinese site available. The simplified Chinese version of Planet Four provides a perfect opportunity for people in China to join the exciting cutting-edge project to enjoy and experience the amazing images of Mars.


我是中研院天文所的软件工程师,生长于中国东北。我很荣幸能帮助第四行星翻译简体中文网站。2014年三月,Meg 在 中研院天文所组织公众科学研讨会。从一个星期的研讨会中,我了解到, 来自世界各地的志愿者朋友们利用他们的闲暇时间参与宇宙动物园的项目,来帮助科学家们分类海量图像,可是却还没有很多国内的志愿者朋友参与。这其中主要的 原因是缺乏相关讯息,因为宇宙动物园的项目还没有简体中文网站。前一段时间Meg请我帮忙翻译第四行星的网站,我欣然答应。希望第四行星的网站可以给国内的志愿者朋友们提供一个了解火星的平台,让更多的人能够参与这个令人兴奋的项目,体验前所未有的精彩火星图像。


欢迎光临「第四行星」。行星科学家正在计算测量火星地表特征,很 需要你的辨识和协助。在此和你面对面的火星地表图像非常独特,绝对都不会在地球上出现,因为每张图像都取自火星的南极!对火星南极这块陌生区域,我们的了 解仍极有限,其中大部分是人类未曾亲眼见到过的火星景象!


我们需要你帮忙找出火星地表上的「扇形」和「暗斑状」的图(以下简称「扇形」、「暗斑」),并且用框线的方式做出标识。科学家认为这些形状特征代表 风向和风速。只要持续追踪「扇形」和「暗斑」,经过几个火星年后,我们将会渐渐知道这些特征是如何形成、发展以及它们会怎样消失和变化,这能帮助行星科学 家深入了解火星气候。此外,如果相同特性总在相同地点形成,也将有机会认识到这些地表特征会怎样在经年累月后发生变化。




Welcome to Planet Four!

Welcome to Planet Four, a citizen science project designed to help planetary scientists identify and measure features on the surface of Mars . . . the likes of which don’t exist on Earth. All of the images on this site depict the southern polar region, an area of Mars that we know little about, and the majority of which have never been seen by human eyes before!

What am I looking for?

We need your help to find and mark ‘fans’ and ‘blotches’ on the Martian surface. Scientists believe that these features indicate wind direction and speed. By tracking ‘fans’ and ‘blotches’ over the course of several Martian years to see how they form, evolve, disappear and reform, we can help planetary scientists better understand Mars’ climate. We also hope to find out if these features form in the same spot each year and also learn how they change.

Why do you need our help?

There are far too many images for a group of scientists to get through alone and computers are just no good at detecting the features we are trying to mark. The human mind is far superior at analyzing images with the complexity of the Martian surface!

Your markings will be collected together with the markings made by other volunteers on that same image. Taking an average of these markings, we will produce an extremely reliable map of the ‘fan,’ and ‘blotch’ features on the surface of Mars and the first large scale measurement of wind on the planet.

Planet Four Now Available In Traditional Character Chinese


歡迎光臨第四行星!We’re pleased to announce that Planet Four has been translated to traditional character Chinese thanks to the Education and Public Outreach (EPO) office at  Academia Sinica’s Institute of Astronomy & Astrophysics (ASIAA). A big thank you to Lauren Huang for translating and Mei-Yin Chou for verifying the translation. I’m a postdoctoral fellow at ASIAA and Lauren, Mei-Yin, and I will  be introducing Planet Four and the new translation to educators from around Taiwan at a teacher workshop on March 2nd as part of a larger workshop on Citizen Science in Astronomy  hosted at ASIAA from March 3-7th. Michael and I will both be attending the full workshop as well.

Also many thanks to the Zooniverse’s Chris Snyder for getting all the technical things set up for the translation to go live on the site in time for the teacher workshop, and thank you to the Zooniverse’s Rob Simpson and Michael Parish for their help as well.

Are you interested in helping translate Planet Four into other languages? Find out more here. 

What follows is the announcement from ASIAA, in English and then in traditional characte Chinese regarding the new Planet Four translation.


No rocketship required, help scientists study Mars from Earth

We need your help to explore Mars. On Planet Four (, you will be shown images of the South Pole of Mars taken by the HiRISE camera aboard the Mars Reconnaissance Orbiter. We are asking you to mark dark fans and dark blotches that appear and disappear during the Spring and Summer on the South Pole of Mars. During the winter carbon dioxide (CO2) condenses from the atmosphere onto the ground and forms the seasonal ice sheet. The ice begins to sublimate in the spring, and the seasonal cap retreats. The dark fans and blotches begin to appear in the Southern spring when the ice cap begins to thaw and sublimate back into the atmosphere. The fans and blotches then disappear at the end of the summer when there is no more ice left.

We want to study how these fans form, how they repeat from Spring to Spring and also what they tell us about the surface winds on the South Pole. If the fans are places where the wind is blowing, then they tell us the direction and the strength of the wind. Blotches then tell us where there is no wind. This is a task that computers cannot do, but which humans are really good at. We need to collect together many people’s markings and combine the results to be able identify the fans and blotches in the HiRISE. With your help mapping the seasonal fans and blotches, we can better study and understand the Martian climate. Explore Mars today at!

(Below is Lauren, the translator, wrote to share her excitement: )

As planetary scientists delight in seeing their probes launched into space, now that the Chinese translation of the Planet Four website is finished, we are also excited for more new volunteers from our own country are about to join this project! Either by way of a probe or a newly added translated language, the two things is similar: opening up a gate to a new world always makes us feel great!

Meg asked me to say a few things as to “why I translate the website for Planet Four”. Of course, the number one motive is serving the community! During the translating process, I constantly thought about the participants of zooniverse, that they are voluntarily doing this, offering their time and resource to support science research; it is our duty to put things in clear Chinese with correct science, so that our helpers can enjoy their science quests with pleasure. However, this task is not easy and is impossible if without my colleague’s help! I’d like to thank Dr. Mei-Yin Chou greatly, who helped verifying each paragraph throughout the site.

Chinese proverb says “one step back, a broaden sky” (退一步海闊天空). I guess whenever people have the time to log in this Planet Four website, it could be a time set aside as a retreat designated of Mars exploration. We are all curious to know more about the fourth planet of our solar system and can’t wait to see how the wind blows there! Have fun!

左鄰拉右舍,樓上牽樓下,探索火星氣候需要大家作伙來幫忙。如果你還沒聽說的話,第四行星網站(是個需要靠人來幫忙辨識圖像的地方,這個網站會顯示一些火星南極圖像給你──這些照片都是由裝在火星偵察軌道機上的HiRISE照相機從火星南極現場拍回來的。按電腦程式出題,網站會請分類員對黑色暗斑和扇形圖像做出標示。這些圖像春季出現、夏季消失,地點是在火星南極。冬季時,火星大氣中的二氧化碳(CO2)會在地面上結凍,形成季節性冰席(ice sheet)。當春季來臨,火星南極的冰冠開始融化,昇華到大氣,到盛夏所有冰層都融化的時候,這些黑色扇形物跟斑點就全部消失了。
