Given recent events on Kepler, it seems like a good idea to start looking at the replacement missions.  So here is a starter on TESS.

There is a reasonable summary from Ricker et al here: https://arxiv.org/abs/1406.0151
Latest expected science yield: https://arxiv.org/abs/1804.05050
Main archive page: here

Note: I will update this post to add further links to the archive manual, target catalogues, etc as they become available.

Looks like the link expired since it was posted 4 years ago.  Here's a copy of the presentation.

Bumping this thread for post-launch TESS updates

Both solar arrays deployed following separation, TESS is a live spacecraft.

When I say "Jump!", you say "To which orbital inclination?"

Given the emphasis TESS will give to the northern and southern celestial poles, I'm curious what targets are out there in those regions.  Kepler (initially) targeted a region just off the Milky Way by comparison.

First light is expected on Tuesday 24th April.

This will be followed by a couple of months of commissioning before science observations begin.

Keep in mind that the TESS targets are suppose to be within a few hundred light years range.

Think the Northern ans Southern Celestial poles gets more coverage from the fixed field of view of the cameras. There are notable longitude coverage gaps in the TESS search sphere area during the initial 2 year primary mission period.

I expect they will pick around 6,000 stars to monitor at 2 minute cadence in the polar regions.  I've updated the top post with the latest expected yield paper - this is well worth a read.

Hmm ... I don't think I'd describe the small longitude gaps as "notable" (see figure 7 of the Riker paper in the top post).

There is a 6 degree *latitude* gap at the ecliptic equator.
