I hope not, and i dont know how reliable this information is, as its from Fox, and i cant find another source as yet.
It seems the problem they had with placing the soil in one of its 8 ovens, where they had to shake the arm to get the soil in, caused a short circuit,
so they are treating the next oven test, as their last.

Engineers said a short circuit that occurred last month in one of its test ovens designed to shake and bake minuscule soil samples could happen
again when the instrument is turned on.

"Since there is no way to assess the probability of another short circuit occurring, we are taking the most conservative approach and treating
the next sample ... as possibly our last," the NASA mission's chief scientist, Peter Smith of the University of Arizona in Tucson, said in a
statement Wednesday.

Initially, the clumpy dirt could not fit through the oven's opening so scientists vibrated the instrument several days to break it up. Engineers
think the short circuit occurred as a result of the repeated shakes.
I suppose there are other instruments on board, cant they continue with them?
