Do Not Open Until Hannukah

My interest is officially piqued -- the Mars Science Laboratory team has found something on Mars.

What?

They're not telling.

Not yet, anyway.  Speculation abounds, but most people are guessing some sign of life (past, probably) or water.

I'm hoping for something cooler -- instructions on how to build a jump drive, maybe, left there by a wandering merchant ship two hundred thousand years ago.

Or keys to a hangar full of working space ships?

But yeah, okay.  A nice aquifer (past or present) would also be cool.
