It's not entirely obvious to me why the sol 65 thread was closed, but I'll assume it is time to move discussions to the extended mission thread. The following quote is from the previous thread. If I've misplaced this comment, hopefully the mods will move it.

Found another story on the perchlorates. Most of it old news but I at least had not seen this before ...

That was a pretty interesting story, and a nice summary of the work done so far. I can't help but wonder if perhaps this ClO₄^- story has really surprised the Phoenix team at this late date in the mission. Has the robotic arm delivered enough samples from enough locations to the various instruments to define the extent of the perchlorate ions, and if indeed there are any perchlorate concentration gradients?

It sounds like a tricky wicket to me, so lately in the game.
