On January 15, 2006, the Stardust spacecraft"s sample return capsule parachuted gently onto the Utah desert. Nestled within the capsule were precious particles collected during Stardust’s dramatic encounter with comet Wild 2 in January of 2004 and something else, even rarer and no less precious: tiny particles of interstellar dust that originate in distant stars, light-years away. They are the first such pristine particles ever collected in space, and scientists are eagerly waiting for their chance to "get their hands" on them.
By asking for help from talented volunteers like you from all over the world, we can do this project in months instead of years. Of course, we can"t invite hundreds of people to our lab to do this search—we only have two microscopes! To find the elusive particles we are using an automated scanning microscope to automatically collect images of the entire Stardust interstellar collector at the Curatorial Facility at Johnson Space Center in Houston. We call these stacks of images focus movies. All in all there will be nearly a million such focus movies. These are available to Stardust@home users like you around the world. You can then view them with the aid of a special Virtual Microscope (VM) that works in your web browser.
Bisher ist Stardust noch kein wirkliches BOINC-Project, sondern "Handarbeit"!

von Cori | Habe heut ne Email von Stardust bekommen, in der Phase 2 angekündigt wird:
| Zitat: | Dear O'Cloud,
We are writing to let you know about an exciting new phase that is about to begin in the Stardust@home search. Ever since we launched Stardust@home nearly a year ago, you and other dedicated "dusters" have proved incredibly successful at detecting possible particle tracks in the Stardust interstellar collector. We can truly say that the ability of our dusters to pinpoint even the smallest and most subtle features in the aerogel has been a constant source of amazement to us. Some of these features may well turn out to be the very first solid samples of matter from outside the solar system ever collected.
Now we can do even better. We are currently reprocessing the images we took of the Stardust collector so as to double the magnification of the focus movies. By scanning these new movies our dusters will be able to pinpoint even smaller and subtler potential tracks. A new stardust track hunt, of unprecedented sensitivity, will be on!
But first -- a short break. In order to launch this new Stardust@home "Phase 2" we will first need to end the current phase and take the virtual microscope (VM) off line for around two weeks. Our plan is to close down the VM between July 27 and August 9. The training and testing features, as well as the actual search for particle tracks, will all be unavailable during this time. We hope to have the forums and the rest of the website open during the transition.
When we temporarily disable the Stardust@home VM, we will also finalize the results of all the dusters who took part in Phase 1. The scores, rankings and candidate lists from this phase will all be preserved and permanently displayed on the Website. When the new Stardust@home Phase 2 launches in early August all dusters will begin anew with a clean slate and an equal chance at discovering more candidate stardust tracks. For more information on our transition to Phase 2 see our website at http://stardustathome.ssl.berkeley.edu/forum/viewtopic.php?t=1858.
We thank you all for your amazing contributions to Stardust@home, and we look forward to the next phase of this historic project. Your talent and dedication to this project have been truly impressive. We couldn't do it without you!

Site Problems and a Candidate Evaluation Plan
More new candidate evaluation comments from the Berkeley Team have been posted to the database this week. You can see them by viewing your My Events page...

Over 20 Million Served!
As of October 6th, 2006 the Stardust@home collaborators have performed more than 20 million searches! More than a quarter of the aerogel collector has been scanned and those focus movies uploaded.

How do you work with a $200 million collector? An update.
On September 18, the Stardust@home project director, Andrew Westphal, presented the current status of the Stardust@home search to the CAPTEM Stardust Oversight Committee at the Lunar and Planetary Institute near NASA Johnson Space Center in Houston. Dr. Westphal is also the chair of the committee, but he set aside that role when making this presentation. The question at issue was: how do we further investigate the candidate interstellar tracks that Stardust@home collaborators -- you!! -- have identified, with minimal risk to the collector?

von Cori | Juhu, hab was gefunden! Also vielleicht wenigstens... 
Habe gerade noch mal meine "Event"-Liste angeschaut, da ist tatsächlich ein Fund dabei, der inzwischen einen offiziellen Kommentar vom Stardust@Home Team bekommen hat: "IS candidate? WCO".
WCO steht für "worth checking out", der offizielle Status dieses Movies ist: "Passed cut 1". Bin gespannt, was die weiteren Tests ergeben!
Da macht die Suche doch gleich wieder richtig Laune, wenn was dabei ist, was möglicherweise echter Sternenstaub ist! |
