Probably this:

"CO2 splitting, CO2 → CO + 1/2 O2"

ARRGGHH!!! . . .
Oxygen exists in a Diatomic state/molecule.
2 x CO2 --> 2 x CO + O2 :box:

Isn't that the same equation?
You can't have O but you can have half as much O2.
MikeK:
I'm assuming the authors of that article knew what they were talking about when they wrote that equation.

In a volumetric sense, I suppose - but in chemical formula expressions, I was never guided into half of anything. You get multiples of whole molecules in a result - not half ones.

Fourth flight is impressive:
"872-foot (266-meter) round trip"
Would be nice if this could do some scouting for the rover. Would be really nice if it would video a descent into one of the caves.
