Impressive, but I just bet we're going to get MHers quoting a bad analogy made in that article:

Van Leeuwen said the satellite's data may be old, but its accuracy is still impressive. "If the satellite was on Earth, it would be able to see a child on the moon take a step," van Leeuwen told SPACE.com.

They say it will record an equivalent of 20 Thousand DVDs of raw information on the stars in our Galaxy

Is the catalog of stars to observe complete yet (I assume they are cataloged well before launch)?

This is a very ambitious project for a five year mission, in my opinion. I imagine it will be many years after that before the first data releases are made public. Have they given any estimates to catalog completion? 10 years, 15 years?

As far as I know, several mega-star catalogs are still far from complete and several have missed their targeted release dates by quite a while.
