This is about two fundamental observations with regard to Wikipedia. One has to do with space: There’s always space, because our encyclopedia will never run out of paper. The other observation is about time: You have all the time in the world to edit Wikipedia. Do it whenever you feel like adding to the sum of all human knowledge. Wikipedia is never finished, just keep contributing. No editorial deadlines, no character limits.

However, we want to challenge these basics for a once-in-a-lifetime opportunity: In the year of Wikipedia’s 15th anniversary, the global community is given a very special birthday gift. We can send the free encyclopedia to the Moon! Literally.

And this is how it works: A group called “Part-Time Scientists” are about to send a rover to the Moon and they are planning to take the Wikipedia with them. The Part-Time Scientists are one of a handful of international teams that compete for the “Google Lunar XPRIZE”. The competition started in 2007, challenging science enthusiasts from around the world to bring a rover to the surface of the Moon, get it to drive at least 500 meters and send images to the Earth. Many have accepted the challenge, only a few are nearing the finish line. The Part-Time Scientists, based in Berlin, Germany, are among them. Their very own Moon rover comes with room for a number of scientific experiments and special data discs that are made of ceramic. Having been great Wikipedia fans for years, the Part-Time Scientists are offering Wikimedia Deutschland the chance to use one of the discs for Wikipedia content.

We have accepted the challenge and are committed to make this project a gift to the global Wikipedia community, because we are convinced that there is only one way to honor 15 years of collaborative vision and volunteer enthusiasm: For the community, by the community.

In 2001, Wikipedia hit the start of the new millennium and nobody could have imagined that 15 years later, this open, bold, and pioneering experiment would account for the most extensive snapshot of human knowledge in our times.

In 1977, the Voyager mission used the famous “Golden Record” to send greetings, music samples, and some images to outer space. Let’s make this challenge our “Golden Record 2.0” and create collaboratively a time capsule of both, knowledge and spirit. Wikipedia to the Moon!

Wikipedia is free knowledge. Anyone can use it and re-use it. Why don’t we just take an open dump and put it on the data disc? Well, it’s a bit more complicated than that: The English-language Wikipedia alone is much bigger than the available storage volume of about 20 Gigabyte. And that is not counting edit histories or any media files at all, just plain text of the current revision. What is more, even though the English Wikipedia contains by far the most articles of any of the Wikipedias, there are almost 300 language versions of the free encyclopedia. In short, disc space is limited while Wikipedia is abundant. Thus, there needs to be a selection of content, which reveals the true challenge behind the project: What do we choose? Who gets to decide? How do we do this?

These questions are all rooted in one of Wikipedia’s greatest strengths. Knowledge varies, and so do Wikipedia articles in their respective language versions. There isn’t a canonical knowledge core, from which all translations in every of the hundreds of languages could be copied from. To the contrary, content in various languages is shaped by numerous conditions, including but not limited to cultural factors, the number of editors, rules specific to language communities, access to the internet and many more. But if you get the chance to bring the sum of all human knowledge to the Moon, should you not strive to represent the same diversity that has made Wikipedia the world’s most famous collaborative project to date?

During Phase 1 (discussing scenarios) the project Wikipedia to the Moon is just an internal discussion what Wikipedia data should be send to the Moon. This discussion is meant to involve mainly the communities of the Wikimedia projects. Once it is decided how the project will be shaped, phase 3 (working) starts in July 2016. We plan to reach out to a broader public to invite everybody to get involved and to share their knowledge to be brought to the Moon.
