Strong support for Europeana from Neelie Kroes

November 10, 2010 9:27 AM

Neelie Kroes, European Commission Vice-President for the Digital Agenda, says Europeana can be a world leader, if it is able to share the full wealth of written and multi-media material held in cultural institutions across Europe.

The comments came during a recent speech at the Forum d'Avignon, an international meeting for culture, economy and media.

"What a digital wonder this is: a single access point for cultural treasures that would otherwise be difficult to access, hidden or even forgotten," said Kroes about Europeana. She also stressed the importance of Europeana being able to display more 20th century materials, including orphan works and out-of- distribution works.

IKAROSJapan launches Venus orbiter and solar sail experiment

By Physics Today on May 21, 2010 9:32 AM

Physics Today: The Japan Aerospace Exploration Agency yesterday launched two scientific spacecraft aboard a single H-IIA rocket.

The 640-kg Akatsuki (“daybreak”) is now on its way to a rendezvous with Venus in late December or early January. From its orbit around the planet, the spacecraft’s suite of instruments will study lightning, volcanism, and other active Venusian processes. The objective of the rocket’s other payload, the 300-kg

IKAROS (Interplanetary Kite-craft Accelerated by Radiation Of the Sun), is to assess the feasibility of propelling spacecraft solely with solar energy. In a few weeks’ time, IKAROS (depicted at right) will unfurl a 14 × 14 m2 sail that will harvest the momentum of solar photons. Embedded in the sail are thin solar cells that will power the spacecraft’s electronics and drive a second means of locomotion and maneuver: an ion propulsion engine.

Japan to Launch Mission to Venus and Solar Sail on Monday

The Planetary Society Is Mission Participant

Pasadena, CA, — Japan's AKATSUKI mission -- the Venus Climate Orbiter -- will launch Monday, May 17 along with the IKAROS solar sail. Flying aboard both spacecraft are the names of The Planetary Society's members as well as greetings from others who signed up to send their names and messages to Venus.

AKATSUKI -- which means "dawn" -- is designed to explore the atmosphere of Venus, and its scientific instruments include cameras that will study the planet in wavelengths from ultraviolet to the mid-infrared. The mission's goal is to help answer the question of how Venus and Earth, sister worlds in size and composition, evolved into such different planets.

The second mission's name, IKAROS, stands for Interplanetary Kite-craft Accelerated by Radiation Of the Sun. It is a solar sail that is designed to employ both photon propulsion and thin film solar power generation during its interplanetary cruise. Read more...


IKAROS vor dem Start

Die Japanische Raumfahrtbehörde JAXA will mit der Raumsonde IKAROS demonstrieren, dass man Sonnensegel bei Tiefraummissionen für Antrieb und Energiegewinnung einsetzen kann.

IKAROSIKAROS (Interplanetary Kite-craft Accelerated by Radiation Of the Sun) soll gemeinsam mit Akatsuki, einer Sonde zur Erforschung des Klimas auf der Venus, Mitte Mai mit einer HII-A-Trägerrakete auf den Weg gebracht werden. Während Akatsuki (auch Planet C oder Venus Climate Orbiter) Kurs auf unseren inneren Nachbarplaneten nimmt, wird Ikaros auf eine Bahn ins innere Sonnensystem entlassen.

Hier soll ein quadratisches Sonnesegel mit einer Diagonale von 20 Metern durch Rotation entfaltet werden. Dabei ist geplant, dass vier Massestücke, die an den Ecken der Folie befestigt sind, diese straff ziehen. Auf einem Teil der Kunststoffmembran mit einer Dicke von nur 7,5 Mikrometern (0,0075 mm) sind Dünnschichtsolarzellen aufgedruckt, welche die Energie zum Betrieb des neuartigen Raumfahrzeugs liefern sollen.

Les données que nous voulons garder vont-elles s'effacer ?

"Why focus on long-term preservation of digital information, while storage capacity has never been so vast and cheap?

RapportThis question raises a problem more and more important: our societies produce growing masses of information, even though the lifetime of digital media available to store has never been short. Storing or backing in the short term does not raise any particular issue, but check in this way over decades or a century poses a different problem, in that digital media have a lifespan of 5 or 10 years."

Longevity of Digital Information backside"The evolution of these materials is difficult to predict, only a constant monitoring of data and their migration will ensure perpetual archiving, with a significant cost to organize.

If this problem is properly addressed in a few specialized agencies, it is widely ignored by the general public and the majority of institutions or companies. A significant amount of personal information, medical, scientific, technical, administrative, etc.. Is thus in real danger of extinction."

"This report gives an exact boundaries by focusing on the fraction of the information that keeps its value over the long term papers or personal (family memories, medical data, ...), either public (scientific data acquired during unique experiences, ...). Possible strategies are discussed and various storage media used are reviewed, with a brief discussion of their respective qualities and limitations. The report also assesses the possible spread of the active strategy to all the needs of society. Finally studied are recordable digital optical discs, for which a series of alarming has been performed recently. The authors propose some avenues that could lead to recordable discs much better longevity and issue four recommendations likely to be aware of this general problem and possible ways to solve it."

Extrait :

Un rapport souligne le risque d'amnésie engendré par le vieillissement prématuré des supports de données digitales. Les données que nous voulons garder vont-elles s'effacer ? » Tel est le sous-titre d'un rapport commun des Académies des sciences et des technologies intitulé « Longévité de l'information numérique », rendu public lundi 29 mars. On croit à tort que les données digitales peuvent être conservées indéfiniment. Le rapport tord le cou à cette idée. Les supports numériques, qu'il s'agisse des disques durs, des mémoires flash, des bandes magnétiques ou des différentes générations de disques optiques, ont progressé en termes de capacité de stockage à court terme.

Glass DVD auf dem Mars
Visions of Mars, on Mars
This image shows the DVD provided by The Planetary Society to the Phoenix mission, which contains 250,000 names of people who signed up to send their names to Mars. It also contains "Visions of Mars," messages to future Martian explorers, science fiction stories and art inspired by the Red Planet. The DVD is mounted on the deck of the lander, which sits about one meter above the Martian surface, visible in the background. Credit: NASA / JPL / U. Arizona

The Phoenix DVD


Phoenix touched down safely on the surface of Mars at 23:38 UTC (16:38 PDT). Follow the mission at The Planetary Society's blog.

Phoenix Carries First Martian Library and 250,000 Names. Find out more.

Did you send your name to Mars on Phoenix? You can still find and print your participation certificate.


After landing, the spacecraft's scientific instruments will come alive, and begin their search for water ice in the harsh Martian environment. Nestled among busy instruments, a small and very special DVD will wait patiently for its turn. This unique DVD is made of silica glass, and designed to last hundreds if not thousands of years into the future, when its true mission will commence. It carries nothing less than a message from our world to one centuries away, when humans will roam the Red Planet.

In a unique project called Visions of Mars, the Phoenix DVD carries personal messages from visionaries of our own time to future visitors or settlers on Mars. There is Carl Sagan near his home in Ithaca, New York, addressing the future Martians with a cascading water fall in the background. There is Arthur Clarke seated in the comfort of his home in tropical Sri Lanka. There is Planetary Society Executive Director Louis Friedman, speaking from Society headquarters in Pasadena, and there is Phoenix mission PI, Peter Smith, providing mission information and a greeting to the future.

Others speak to the future not directly, but through their visionary works, which shaped our imaginings of the Red Planet. A wealth of influential pieces are included in Visions of Mars, which was assembled and edited by Planetary Society advisor Jon Lomberg. Percival Lowell, in beautiful poetic prose, expounds his theory of the "Mars canals," and the intelligent beings that built them. H.G. Wells, in War of the Worlds, imagines what such desperate creatures might do to our own beloved Earth. The recording of Orson Welles' 1938 radio broadcast of this classic tale -- which set off a wave of panic across the United States -- is also digitally encoded on the Phoenix DVD. Louis Friedman contributed an afterword, describing the origins and history of Visions of Mars, and how it came to be.

Among those included in this remarkable message to the future are Isaac Asimov, Ray Bradbury, Poul Anderson, a musical production of Bob Derkach's "Winds of Mars," and many others. A collection of rare Mars artwork, reflecting our changing images of our neighboring planet can also be found on the Phoenix DVD. All this, and much, much more, from the visionaries of the past century, whose dreams of Mars shaped our own.

Thousands of People will be there with Them.

Thousands of people from around the world, joined our age's visionaries of space exploration by adding their names to this remarkable message to the future! The Planetary Society collected names, which are now on Mars on the Phoenix DVD. When the Martians of the future find and decode our message to them, their names will be there too, a permanent record of their part in the story of space exploration.

science publiqueQuelle durée de vie pour l’archivage numérique ?

Selon le cabinet d’études Infotrends, le nombre total d’images numériques enregistrées dans le monde depuis que cette technologie existe atteignait l’an dernier les 180 milliards. Et il devrait bondir à 347 milliards d’ici 2012. Soit presque un doublement en quatre ans. Et il ne s’agit là que des images. Il faut y rajouter le texte, le son et la vidéo. Car aujourd’hui, tout est devenu numérique. Même la télévision. Et bientôt la radio. Cette conversion généralisée à la forme issue de l’informatique a posé un problème important aux organismes chargés de conserver la mémoire officielle de l’activité humaine.
En quelques années, le métier des grandes bibliothèques et autres banques d’images, de musique ou de films a radicalement changé. Il ne s’agit plus de conserver du papier, des pellicules, des disques en vinyle ou des bandes magnétiques mais bien des « données ». C'est-à-dire des suites de 0 et de 1. Comment stocker de telles informations immatérielles ? Bien sûr, l’industrie a créé des supports bien matériels pour y graver la mémoire numérique. Le plus populaire a été inventé il y a tout juste 30 ans, en 1979. Il s’agit du fameux disque compact audio, le célèbre CD. Une petite galette de 12 cm de diamètre pour 1,2 mm d’épaisseur qui a donné naissance au DVD en 1995 et au Blu-Ray en 2006-2007. Soit une capacité de stockage multipliée par près de 40 en moins de 30 ans. Ce support ainsi que d’autres comme les disques durs ou les mémoires flash servent aujourd’hui à archiver des quantités astronomiques de données numériques produites dans le monde entier. Mais pour combien de temps ?
Une question presque saugrenue tant les supports d’information numériques semblent éternels… Et pourtant, fin 2007, un scientifique du CNRS, Franck Laloë, a tiré le signal d’alarme dans le magazine Pour la Science puis dans le journal Le Monde . La durée de vie des supports numériques serait bien plus courte qu’on ne l’imaginait. Pas plus de dix ans, selon lui. Comment les professionnels de l’archivage, mais également le grand public, vont-ils pouvoir, dans ces conditions, transmettre notre mémoire numérique aux générations futures ?

Phoenix DVD with 250,000 Names Ready to Launch to Mars

The Phoenix DVD

May 23, 2007

As part of our Messages from Earth project, The Planetary Society collected names to travel to Mars on board the Phoenix lander. I'm happy to announce the silica glass mini-DVD with a quarter million names on it (including all Planetary Society members) has been installed on the Phoenix spacecraft and is ready to go to Mars!

In addition to the names, the disc also contains Visions of Mars, a collection of literature and art about the Red Planet. The names and Visions of Mars were written to the silica mini-DVD by the company Plasmon OMS using a special technique. The resulting archival disk should last at least hundreds of years on the Martian surface, ready to be picked up by future explorers.

After the disc was written, a special label was applied to the disc to identify it for future explorers. Then, the whole assembly was "baked out" (to kill microbes and also to reduce future outgassing of the materials), and Lockheed Martin in Colorado installed it onto the spacecraft.

After installation, the spacecraft underwent further testing and assembly, was shipped to Cape Canaveral, and is now being prepared for its August launch to Mars. Phoenix will arrive and land in the northern near-polar regions on Mars in late May or early June 2008 (exact date depends on actual launch date).

We'll keep you posted on the mission as it progresses towards launch, and of course, update you on its launch and landing.

Next stop: Mars!
