I challenge you not to look at this and make a ping/spring/boing happy sort of a noise.

The Organic Free Blank (OFB)
http://www.lpi.usra.edu/meetings/lpsc2008/pdf/1067.pdf (top of page 2) QUOTE The Phoenix OFB will be used only if organic C is detected on Mars by TEGA. The OFB will then be sampled and analyzed, and results will be compared to the organic signatures released by the Martian sample. After OFB analysis, a TEGA run will be conducted on a second sample of the putative organic-containing material to validate the first analysis. High concentra-tions of organic molecules and possibly organic frag-mentation patterns not in the OFB will also contribute to a credible positive identification of organic mole-cules indigenous to Mars. The high total carbon con-tent in the OFB FM (1.6 μg C g-1 of sample) may re-quire that the total C content in the Martian materials substantially exceed this number, perhaps as much as 10 μg C g-1 of sample before a positive detection of organic molecules on Mars is credible.

We do not want talking about the subject of the press conf, don't we ? They are probably going to unveil a picture of a beautiful sunset. That's all. -------------------- If Occam had heard my theory, things would be very different now.

Mmh, during the last press conf they wore a witch hat to talk about Wicked Witch.
I wonder if they'll talk about Snow White today. |
