This Wednesday, November 12 02014, the European Space Agency‘s Rosetta Mission will deploy the Philae lander onto the 67P Comet after over a decade-long journey.  When this mission was first conceived, the ESA asked to put one of Long Now’s Rosetta Disks on the craft, making the Rosetta Probe the first off-world long-term archive of human language.

To honor the culmination of this historic mission, ESA has released a short science fiction film imagining the potential legacy of the Rosetta Mission. This dramatic, inspiring short was directed by Tomek Bagiński and co-stars Aidan Gillen (of The Wire and Game of Thrones). It’s a reminder of how historic this mission truly is.

On November 12, 02014 from 6:00am to 9:00am PT, you can watch the live stream of the Rosetta Space Probe (which carries our Rosetta Disk) sending its lander, Philae, down to comet 67P.

Here in the Bay Area, The Long Now Foundation is partnering with the Chabot Space Center and swissnex SF to host a breakfast event at the Chabot Space & Science Center. The event will feature the live stream and our own Dr. Laura Welcher giving a presentation about the Rosetta Disk, as well as Chabot’s staff astronomer Ben Burress and a live Skype with Kathrin Altwegg from the European Space Operations Centre, Darmstadt. Doors & breakfast are at 6:00am; tickets and more information can be found here.

For over a decade, Long Now has closely watched the European Space Agency’s Rosetta Mission as it has orbited the Sun in search of comet 67P and untold scientific breakthroughs. This pioneering space probe was launched in early 02004, maneuvered itself into orbit around comet 67p earlier this year, and on November 12 it will be the first human-made craft to make contact with the nucleus of a comet.

Where is Rosetta?

For the latter purpose, the Rosetta probe carries Philae, a small landing craft bristling with scientific instruments and the harpoons and drills necessary to “landing” on a low-gravity object like a comet. At just four kilometers in diameter, comet 67P’s gravity is but a millionth of what we feel on Earth, which makes the landing a uniquely challenging endeavor.

While Philae descends towards the comet’s surface and immediately after it has touched down, it will perform a bevy of tests and observations in order to send back as much data as possible – via Rosetta, still orbiting the comet – in case any part of this tricky maneuver goes awry and damages or destroys the craft. Assuming the landing and deployment of Philae’s instruments goes according to plan, the probe will continue to monitor and study the comet as it approaches the Sun and heats up. At some point in March of 02015, it is expected that comet 67P’s proximity to the Sun will cause Philae to overheat, ending its useful life.

While Rosetta has been in orbit around comet 67P, it has been studying the terrain in search of a relatively safe landing spot for Philae. The comet’s landscape is characterized primarily by jagged cliffs and boulders, but the ESA team identified five potential options before choosing their preferred target for the November 12, 02014 landing.

The location of the Rosetta Disk on the Rosetta Spacecraft

Near the turn of the century, while the mission was coming together here on terra firma, a member of the ESA team contacted Long Now because of our own Rosetta Project.

The ESA’s Rosetta probe was inspired by the Egyptian artifact, just as our Rosetta Project was, because of what an essential historical “key” it represented. By allowing linguists and historians to decipher the long-forgotten hieroglyphics of ancient Egypt, the Rosetta Stone “unlocked” the writings of the rich and long-standing culture that built the Great Pyramids, the Great Sphinx and ruled the Nile delta for millennia.

ESA’s scientists hope that comet 67P will serve a similar unlocking role for our understanding of life on Earth. It’s hypothesized that the molecules that eventually became DNA and gave rise to all living things on our planet came not from the Earth itself, but instead from comets and asteroids of the early solar system. By landing Philae directly onto the comet’s surface, scientists will have their first opportunity to directly analyze the material of a cometary nucleus for signs of the ancient organic molecules that can confirm this theory.

Long Now’s Rosetta Project has created a micro-etched, nickel disk meant to last thousands of years that houses an archive of human languages so that future archaeologists and linguists might be able to unlock the writings of civilizations whose languages are likely to be lost in coming centuries.

Inspired by the resonance of this hope to unlock knowledge of the past and future, the ESA team offered to put a copy of the Rosetta Disk on the Rosetta Probe and at this very moment an archive of 1,500 human languages is floating out among the solar system, in orbit around comet 67P.

After more than a decade, ESA’s Rosetta Mission arrives at Comet 67P

After ten years, five months, and four days of travel, the European Space Agency’s Rosetta Mission has finally rendezvoused with the 67P comet. The Rosetta mission woke up back in May and has subsequently been maneuvering towards the comet. This is the first mission dedicated to exploring comets, a little understood but important part of our solar system:

Comets are considered to be primitive building blocks of the Solar System and may have helped to ‘seed’ Earth with water, perhaps even the ingredients for life. But many fundamental questions about these enigmatic objects remain, and through a comprehensive, in situ study of the comet, Rosetta aims to unlock the secrets within.

Now that Rosetta has reached the comet, it will slowly approach the comet, mapping the terrain for landing locations and eventually locking into a close orbit:


During development of the mission the ESA invited Long Now to include one of our Rosetta Disks on the probe. And so this ESA mission is not only the most detailed comet researcher ever, it is also the first off-world archive of thousands of human languages.

The Rosetta Project is Long Now’s initiative for long-term archiving of human languages. The disk includes parallel texts (inspired by the original Rosetta Stone) and thousands of pages of information documenting languages from all over the world. The Rosetta disk that is on the probe is an early prototype, a more recent design is shown below:

The Rosetta space probe had been in hibernation since 02011, having completed several flybys and slingshot maneuvers after being launched in 02004. San Francisco’s Exploratorium marked the ESA’s successful re-awakening of the probe in January and will have another event this Thursday to discuss the most recent developments.

Comets generally have very eccentric orbits, meaning they travel in very squished ellipses, rather than perfectly round circles. That eccentricity causes the comets to oscillate between the outer reaches of the solar system and relatively close passes by the Sun. Comet 67P is on its way in toward the Sun right now and that means it’s heating up. This causes ice to melt and boil and eject gas and dust from the comet’s nucleus, creating the characteristic comet tail. The Rosetta mission will orbit 67P for 17 months, through its closest approach to the Sun and then out again. This will provide an unprecedented level of detailed data as the comet goes through the significant changes caused by drastic changes in temperature.

After 17 months of orbit and study from above, the plan is for Rosetta’s Philae lander to drop onto the comet itself in November. It will drill into the surface of the comet and perform experiments to learn more than ever before what composes a comet. And you can follow its progress on Twitter.

Advanced Tickets are strongly encouraged as space is limited

Long Now’s Rosetta Project is dedicated to documenting and preserving human languages. In 02014 preservation is crucial because the languages of the world are dying at an unprecedented rate. And that’s only part of a larger problem.

The link between language diversity and biodiversity is well established. A quarter of all languages on Earth will not survive this century. When we lose a language we also lose the culture of its speakers, their specialized knowledge of the natural world and their care for it.

On Tuesday, July 22, at The Interval you’ll hear more about the situation and a new initiative between Long Now and the Global Lives Project to document the lives and culture of endangered language speakers and raise awareness of the problem in collaboration with The Hans Rausing Endangered Languages Project and a team from the Smithsonian Institution.

Mandana Seyfeddinipur directs the Endangered Languages Documentation Programme at SOAS, University of London. She is enabling hundreds of groups around the world to document dying languages around the world, some of the most important work going in this field.

The Global Lives Project is a Bay Area non-profit developing a video library of everyday life in cultures around the planet. Global Lives’ unique long-form videos tell a “Big Here” story about people around the world.

Long Now’s salon talk events happen on Tuesday nights at The Interval our bar/cafe/museum at Fort Mason Center in San Francisco. The lineup of upcoming talks is growing. Check out the full list here.

Interval donors hear about our events first: there is still time to become a charter donor.

ESA’s Rosetta Probe begins approach of comet 67P

The European Space Agency’s Rosetta probe has sent some great images back to Earth illustrating its approach as it has pulls to within 2 million kilometers of 67P/Churyumov-Gerasimenko the comet it is targeting. Later this year it will drop a lander on the comet to conduct important experiments on its composition–more on that below.

During development of the mission the ESA invited Long Now to include one of our Rosetta Disks on the probe. And so this ESA mission is not only the most detailed comet researcher ever, it is also the first off-world archive of thousands of human languages.

San Francisco’s Exploratorium marked the ESA’s successful re-awakening of the probe in January and continues to follow its journey. Last month Exploratorium Senior Scientist Paul Doherty spoke with Rosetta Project Scientist Claudia Alexander about recent developments and what scientists hope to learn from this up-close look at a comet.

Comets generally have very eccentric orbits, meaning they travel in very squished ellipses, rather than perfectly round circles. That eccentricity causes the comets to oscillate between the outer reaches of the solar system and relatively close passes by the Sun.

The Algonquian Linguistic Atlas is a project helping to preserve and celebrate North America’s linguistic diversity. The Algonquian family of languages have an estimated 50,000 speakers and the atlas allows viewers to explore the roughly 30 languages within it.

algonquianatlas

The project gives speakers and researchers a common tool to study and share the cutural diversity Native Americans developed over many thousands of years.

Linguist Arika Okrent points out,

It isn’t just a repository of words and stories though. It is organized in a way that lets you explore the similarities and differences between the languages, and see how they are distributed by place.

Pins on the map indicate the locations of speakers who have contributed recordings of common phrases. Choose a phrase to see how it’s spoken in languages all accross Canada and the northern United States.

By doing this, it becomes easy to see the relatedness, but also the divergence of the languages. Is the distance between two speakers a good predictor of how differently they’ll say a given phrase? Give the map a spin and see for yourself.

Lera Boroditsky: How Language Shapes Thought – A Seminar Flashback

In October 02010 Lera Boroditsky spoke for Long Now on How Language Shapes Thought in a talk that resonates with the Rosetta Project, Long Now’s language preservation project.

SALT audio is free for everyone on our Seminar pages and via podcast. Long Now members can see all Seminar videos in HD. Video of the 12 most recent Seminars is also free for all to view.

Twice a month we highlight a Seminar About Long-term Thinking (SALT) from our archives. Members can watch this Seminar video here, and this talk in particular is even better with the visuals.

Lera Boroditsky is a cognitive scientist at UC San Diego (and was previously at MIT and Stanford). She has been named one of 25 Visionaries changing the world by the Utne Reader; other honors include being named a Searle Scholar, a McDonnell scholar, and an NSF Career award. She is Editor in Chief of Frontiers in Cultural Psychology.

In How Language Shapes Thought Boroditsky presents fascinating insights into the relationship between languages and thought. Drawing directly from her own work and other contemporary research, the questions she addresses include: whether those who speak different languages think differently? Does learning a new language shape the way you think? Do multilingual individuals think differently when speaking different languages? Are some thoughts unthinkable without language?

From Stewart Brand’s summary of the talk (in full here):

Lera Boroditsky speaks for Long Now

Time is the most common noun in the English language said Boroditsky. (Followed by person, year, way, and day.) Time is often expressed as travel in space: “We’re coming up on Christmas.” But some languages put the future in front of us, and others put it behind us. For Aborigines that Boroditsky studied in north Australia, time and sequence gets blended into their profound orientation to the cardinal directions. They don’t use relative terms like “left” and “right,” but absolute compass terms (There’s an ant on your southwest leg), and they have extraordinary orientation skills.

She cites a wide range of languages and research from around the world in a scientific tour through cultures and cognition that includes a few experiments with the audience at the Seminar. This is a fun and accessible talk filled with 02000′s pop cultural references like Dick Cheney’s quail hunting mishap and “Freedom Fries”–Boroditsky even has some helpful tips on how to better annoy the French.

The Seminars About Long-term Thinking series began in 02003 and is presented each month live in San Francisco. The series is curated and hosted by Long Now’s President Stewart Brand. Seminar audio is available to all via podcast.

Reviving and Restoring Lost Sounds

Posted on Thursday, December 26th, 02013 by Catherine Borgeson

In 02008 Kevin Kelly called for movage (as opposed to storage) as the only way to archive digital information:

“Proper movage means transferring the material to current platforms on a regular basis— that is, before the old platform completely dies, and it becomes hard to do. This movic rythym of refreshing content should be as smooth as a respiratory cycle — in, out, in, out. Copy, move, copy, move.”

Five years later, Berkeley physicist Carl Haber received the MacArthur “Genius Grant” for doing just this–moving two- or three-dimensional audio recordings on obsolete platforms and/or decaying storage media and digitally restoring them. These long-lost analog sounds can essentially be played with a virtual needle.

Haber already had the technology in place from his research on imaging radiation. He had cameras precise enough to image and measure the patterns of particles and debris that emerged from subatomic particle collisions. He and his colleagues at the Lawrence Berkeley National Laboratory applied this noninvasive image processing to develop IRENE (Image, Reconstruct, Erase Noise, Etc.). They derived the acronym from the first recording used to demonstrate the concept of IRENE–The Weavers performing “Goodnight Irene.”

Just like the detailed technique required to measure radiation, pictures taken at great magnification are needed to map the surface of an audio recording.  One pixel is about one micron on the disc or cylinder surface, meaning in order to acquire a sufficient digital map, the camera scans the object slowly enough to synthesize a gigapixel image:

A disc or cylinder is placed in a precision optical metrology system, where a camera following the path of the grooves on the object takes thousands of images that are then cleaned to compensate for physical damage; the resulting data are mathematically interpolated to determine how a stylus would course through the undulations, and the stylus motion is converted into a standard digital sound file.

So IRENE uses image processing to take a picture and mathematically break down the information in that image to calculate the motion of the groove and determine what sound would actually be played. It’s all done with an algorithm on a computer, never having to touch the recording in the process.

Haber has collaborated with archivists and researchers around the world to test IRENE on a variety of audio recordings. The Smithsonian has about 200 experimental recordings from Volta Laboratory Associates, a collection of some of the earliest audio recordings ever made. It is “a reflection on the intense competition between (Alexander Graham) Bell, Thomas Edison and Emile Berliner for patents following the invention of the phonograph by Edison in 1877.”

Now, in collaboration with the Smithsonian and the Library of Congress, IRENE has started to recover these fragile recordings made out of rubber, beeswax, glass, tin foil and brass. The cryptic recordings on such delicate and damaged storage mediums can presently be heard, over a century later:

Early experimental recordings are not the only recovered lost voices. Anthropologists, linguists and ethnographers were among some of the first to use recording as a research tool and to document cultural heritage. IRENE has restored some of these field recordings, including wax cylinders from the Alfred L. Kroeber collection at the Phoebe A. Hearst Museum of Anthropology in Berkeley. There are over 3,000 cylinder recordings in the collection that document California Native American culture from 01900-01919. Around 300 of these cylinders are 2-3 minute long recordings of Ishi, the only surviving member of the Yahi at the time. 53 of the 300 cylinders are Ishi telling the story of the “Wood Duck” in 01912.

Earlier this month Smithsonian’s National Museum of Natural History received a $1 million grant from the Arcadia Fund to digitize its endangered-language materials, including the estimated 3,000 hours of sound recordings. The recordings will then be electronically available to the public through the Smithsonian’s catalog system:

Digitization of these materials within the NAA (National Anthropological Archives) will give both scholars and local communities new access to documentation of endangered languages and cultural knowledge about threatened environments around the world, ranging from southern California to small Micronesian atolls.

In September 02010, The Library of Congress released the first comprehensive study on a national level examining the preservation of sound recordings in the United States. It found that many historical recordings have already deteriorated or are inaccessible to the public due to their experimental and fragile nature.

“Those audio cassettes are just time bombs,” the study’s co-author Sam Brylawski said. “They’re just not going to be playable.”

But maybe this is not the case after all. Perhaps Haber has taken upon an archaeological endeavor that postpones the detonation of media “time bombs.” It comes back to Kevin Kelly’s idea of movage. Haber has taken big technological steps to digitally play these long-lost analog voices, now the key is to keep on moving.

Wake up, Rosetta!

Almost ten years ago, the European Space Agency launched a probe with the goal of approaching and studying a comet. The probe was named Rosetta because, just as the Rosetta Stone allowed historians to piece together an ancient language and unlock a great deal of human history, the Rosetta probe will give us a better understanding of comets than we’ve ever had and possibly help us unlock a great deal of our solar system’s history.

The ESA invited Long Now to include one of our Rosetta Disks (in early prototype form at the time) on the probe. The Rosetta mission, therefore, serves a second purpose (after its comet research) as an off-world archive of several thousand human languages.

In search of its target, Comet 67P/Churyumov-Gerasimenko, Rosetta performed several slingshot fly-bys of our solar system’s inner planets, the last of which happened in 02009.

Rosetta has been in hibernation mode ever since, speeding its way toward Comet 67P. It needs to wake up in January to begin preparing for its August rendezvous and the ESA wants some help rousing it:

In a competition that opens today, ESA invites you to mark this important milestone in the Rosetta mission by sharing a video clip of you shouting “Wake up, Rosetta!”

You can upload your video clip and share it with the world via ESA’s dedicated Facebook page.

Be creative and imaginative – you can include friends, family, colleagues, members of your team, social clubs, and school groups, or even put together a flash mob to create a memorable video shout.

Creators of the two most popular videos will get to watch the Rosetta probe drop a lander named Philae onto the comet from mission control in Germany! Details and how to enter. You can keep up with the Rosetta mission on Facebook and Twitter.

The Heirlooms of Language Through Temporary Tattoos and a Nickel Disk

Posted on Wednesday, October 23rd, 02013 by Catherine Borgeson

On Saturday October 19, 02013, Long Now participated in Exploratorium Market Days—a series of free, outdoor “mini-festivals” geared to educate the public through the science and art communities and museums. The theme of the month was “Heirlooms,” which focused on the “diverse treasures that we preserve and pass along to future generations.”

Together the Rosetta and PanLex Project staff presented the intangible culture of language in a very tangible way—the Rosetta Disk and temporary tattoos.

The PanLex Project is building an enormous database with the goal of translating all of the words of all of the world’s languages. They created an interface to this database where people could either choose from a list of commonly-used words in tattoos, such as “patience” or “victory,” or enter one of their own choice.

The next screen listed all the translations of that word in the PanLex database, sometimes for hundreds of languages. People were captivated at looking through the list and deciding which language to print their tattoo in. For some, the deciding factor was an interesting script, or because only a handful of people spoke that language. For others it was a language they themselves spoke and personally connected with.

In addition to the PanLex and Rosetta Project staff, Exploratorium Explainers helped run the booth. These are a diverse group of high school students interested in learning new things while explaining and helping others in the process.

Market Day 1

Market Day 2

Market Day 3

On a more permanent role of archiving and preserving languages, the Rosetta Disk was also on display. A steady stream of people viewed the micro-etched languages with a microscope throughout the day.

Market Day 4 Market Day 5

Market Day 6 Market Day 7

Exploratorium’s Director of Public Programs Melissa Alexander invited Long Now to participate in Market Day. She wanted people to get a sense of the vast amount of languages while understanding that like many species, languages are endangered and are disappearing from the planet regularly.

“I had a Ray Bradbury moment–I wanted everyone to learn how to say hello, please & thank you and welcome in at least one endangered language. Loved the setup and clearly our Explainers did too–if our Explainers like it, it’s golden–teenagers are great thermometers.”
