I guess WISE got its mission extension after all. I wonder what changed between these two updates.

I can't find anything more than you. It would seem the panel's decision wasn't executive.

They realized their earlier decision was really unwise.

The brown dwarf harvest has begun. Emily has a post on it (which alerted me) but this article says more about the number already in the pipeline awaiting confirmation/publication, and the possible eventual total: http://www.spacedaily.com/reports/Cool_Sta...A_Find_999.html

Wonder why no big announcement yet. Could it really be there's nothing closer than Proxima? Or does the analysis just take a lot longer than I imagine it should. (A common problem, I should admit.) :-)

I've got a funny feeling that analyzing data from a survey that covers the entire visible (well, visible in IR) universe might just take a wee bit of time...
Not to mention that if you're going to announce that you've found a major astronomical object closer than Proxima, you really want to make sure you've got it right. |

Oooops(?).
It's possible I jumped the gun by a few days, I don't really know. I assumed that when the last dark blue streaks disappeared from the WISE coverage map, that would mean that the second survey was done. But it's possible that some high coverage areas from the first sky scan (which could show up as 16X+) have yet to have their six month checkup. If so, then we're still just a matter of days away from completion. The first survey ran from January 14 to July 17. At any rate, here is the latest. There is going to be a public data release sometime in April. It will cover half the sky from the first survey. So, I expect that we may be hearing about some significant discoveries, if any, before then. Particularly if they are present in the area covered by the release. LINK |

Ran into one of the WISE team and got a little more information on operations. Apparently, the warm mission extension was funded primarily to detect and characterize NEOs, and includes operations only through the end of January.

I suppose at this point a fair question would be whether there would be any scientific value in an additional 6 or 12 months, given that the satellite is already in orbit and such.

I see they're still planning for a public release of data (some of the data) in April, so if they've got a big announcement, they'll probably want to make it before that.

QUOTE NASA's NEOWISE Completes Scan for Asteroids and Comets Looking at fig. 3 in the paper I would say the scan for asteroids needed another 2 months to complete. |

The scan is complete. Read the figure caption:

AU in the gure is due to the exhaustion of the secondary tank's cryogen on 5 August, 2010, resulting in the loss of band W4. |
