The quotes from the www.museumofhoaxes.com post are taken directly from a news article "Stardust@home battles early glitches" published in Nature just 2 days after we launched. This is a good, honest appraisal of the project at that time. Nothing to do with the recent updates.

Replies: 8

Hi The two Stardust collectors were mounted back to back on a single deployment arm. There was nothing in between the backs of the aerogel tiles, but no impacts from either side penetrated all of the way through (tracks that large would have been seen during the initial documentation stage back in J...

Latest Findings: Movie Reviews

Here are some of the movies we have picked out to review. We emphasize that interesting candidates are just that. We have learned from working with the Stardust Cometary collector that it is very difficult to identify tracks while the aerogel is still in the collector frame. We can only be sure abou...

Please see our update on the "cheating" issue http://stardustathome.ssl.berkeley.edu/forum/viewtopic.php?t=874 We can confirm that a small number of volunteers have been boosting their scores by spending their time on calibrations and not the real movies. We can spot this activity in our database an...

Update 16Aug06: "cheaters" vs science!

Several colleagues pointed out on the forum that people could "cheat" by advancing rapidly through the real movies to the calibration movies. Although the "cheaters" only cheat themselves out of an opportunity to find a real interstellar dust particle, we did want to find them so that we could ignor...

Update 11Aug06: reviewing movies

Many of you have been wondering when and how we are looking at movies that have been clicked on. Firstly, we've picked out the top 100 movies with the current highest scores, meaning those with the greatest number of agreements, and we've looked at the focus movies. From those movies we selected a s...

Update 10Aug06: retiring movies

1920 Bad Focus movies have been retired from the VM today. Those retired were the most obvious cases, having 'Bad Focus' or 'No Track' clicked by almost everyone who has viewed them. There will still be a number of movies that are bad focus, since this is an unavoidable aspect of automated scanning ...

Sorry everyone.

This sensitivity = specificity bug was a little mix-up in the VM this morning.
It's been fixed and will push through to the servers in a few minutes.
Your scores should return to normal very soon.


Thanks for the rapid feedback!

Hi

This is a problem where the movie seems to have very few frames.


The VM is functioning correctly. The problem was caused in processing the focus movie.

The answer is to click Bad Focus.


Thanks

After months of delays we are finally ready to begin our search for interstellar particles of dust trapped in the aerogel collector from NASA's Stardust mission! The project will officially begin at 11:00 AM Pacific Daylight Time (PDT) on August 1s...

Nikita - :lol: Wolter, fjgiie - Hi. Yes, you're both right. The lighting is an issue for us. We imaged the Mir and lab aerogel in our lab in Berkeley with all the tricks we've learned in imaging aerogel: reflected light, side lighting and a mirror underneath gives the best possible contrast.

Hi folks just a note to confirm a couple of things: We will open the test at the same time as we launch the Virtual Microscope (VM). Part of the reason is that we are remaking the test to include Stardust focus movies, replacing those from laboratory shots and aerogel flown on Mir that we used in al...
