Systems Engineering for the Kepler Mission

--------------------
"After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance.
I see that such intercourse long continued would make one thoroughly prosaic, hard,
and coarse. But the longest intercourse with Nature, though in her rudest moods, does
not thus harden and make coarse. A hard, sensible man whom we liken to a rock is
indeed much harder than a rock. From hard, coarse, insensible men with whom I have
no sympathy, I go to commune with the rocks, whose hearts are comparatively soft."

- Henry David Thoreau, November 15, 1853

Here is an image of a Milky Way star field in the vicinity of
Alpha Cygni (Deneb).

This image is near the Kepler FOV and gives an idea of the task facing
Kepler. Recall that Kepler will be staring at a star field, containing
about 100,000 - 200,000 stars, for 4 years looking for planetary transits.
This image is part of an on-line collection of classic Milky Way
images obtained by E.E. Barnard. The search page can be found at

I think we should club together and buy Alan a sherif badge smile.gif

All credit to the guy - these are not easy decisions to make - and the best decision is rarely the easiest one.

I really love the Kepler mission concept, and I've been sad to see it delayed so long, but (reading the article) it sure sounds like Alan was spot-on with this one. Sadly, it feeds my perception that most of Nasa's problems are self-inflicted. On the bright side, it suggests things could get much better if Alan keeps making calls like this.

Why this so different from the first Dawn decision?

Too bad Alan wasn't around to prevent the GP-B fiasco.

Slightly related...We've often heard the quote, "That sure would look great in the Smithsonian". Got two questions:

1. Are there any projects that were killed and placed in the Smithsonian, or A&S museums in general?

2. Really, wouldn't you be disappointed to see an unlaunched space probe sitting there in the A&S museum? I think it would be better to mount it in the foyer of the managing team's facility as a reminder. smile.gif

Two examples - one big, one small.

The Saturn V at JSC is built from parts destined for Apollo 18/19 and/or the third stage that got pulled off to make room for Skylab.

And Marie Curie - the Sojourner spare - then destined for the 01 lander, which got cancelled, and never made it onto the Phoenix payload - not sure where she lives now but she's been to exhibitions afaik.

"...The Saturn V at JSC is built from parts destined for Apollo 18/19 and/or the third stage that got pulled off to make room for Skylab..."

I believe there are 3 Saturn 5's on display, the third one at Marshall or somewhere Huntsville, though only 2 flight vehicles remained after Apollo's 18 and 19 were budget canceled. The third vehicle is the dummy pad-checkout vehicle that was used to test VAB/Crawler/Pad operations and connections/hookups before Apollo 4's Saturn 501 was prepared for launch. I read somewhere that parts of it are included in both the Canaveral and Houston display vehicles, so none of the vehicles on display is 100% flight capable hardware.

This is what Wiki says:

Currently there are three Saturn Vs on display, all displayed horizontally:
A Saturn V on display at the U.S. Space & Rocket Center in Huntsville, Alabama.
A Saturn V on display at the U.S. Space & Rocket Center in Huntsville, Alabama.

* At the Johnson Space Center made up of first stage of SA-514, the second stage from SA-515 and the third stage from SA-513.
* At the Kennedy Space Center made up of S-IC-T (test stage) and the second and third stages from SA-514.
* At the U.S. Space & Rocket Center, made up of S-IC-D, S-II-F/D and S-IVB-D (all test stages not meant for actual flight)(soon to be moved to a new visitor's center).


So the JSC one is all flight hardware (and the only one to be so) - just not from the same vehicle.

The space station appears destined to contribute a lot of hardware to these lists.
