In late June, the Mars Phoenix Lander (artistically depicted to the right) scooped up a sample of Martian dirt, dumped it into its Thermal and Evolved Gas Analyzer (TEGA) and made the first unambiguous discovery of water on Mars. On July 7, 2008 the Mars Phoenix Lander put a sample of Martian dirt into its Microscopy, Electrochemistry, and Conductivity Analyzer (MECA) and found... something really exciting, but NASA's not telling what that is. In fact, NASA had a press conference today (Aug. 4) specifically to announce that they weren't announcing anything. However, if the buzz in the planetary science community is any indication, whatever was found is something with implications beyond the Mars science community.
Rumors have been flying that it may be something really exciting - confirmation of past water flow, organic molecules, signs of life, microorganisms playing volleyball, God himself! Ok, maybe not God, but pretty much all of the other possibilities are still on the table. A member of the collaboration that built and operates the TEGA (not the MECA, which is the instrument that found whatever it was) was visiting CU last Friday, got a phone call, yelled into the phone, jumped into the air, and then told everyone that they couldn't talk about it.
While I don't know what will come of this, if NASA hasn't publicly released the information then it means one of two things:
- NASA is doing responsible science and trying to confirm the discovery before shouting it from the rooftops.
- NASA is waiting to give someone higher up on the totem pole (i.e. the head of NASA or President Bush) the chance to make the announcement.
I personally think it's probably option #1. To me, this seems a lot like the possible Higg's boson detection last year at the Tevatron in that it's interesting, but far from a sure thing. Still nothing fuels rumors like a press conference specifically to deny there is anything to announce, so I, for one, will be watching this one pretty closely.
