Drilling is probably the best bet for getting a perchlorate-free sample into the ovens.
Best of all might be drilling into a gypsum vein. A gypsum deposit precipitated from water would be unlikely to contain perchlorate (since perchlorate is much more soluble than calcium sulfate) and might have trapped some material with organic chemicals. In future missions, the simplest method of removing perchlorate from soil samples might be to wash them in sterilized pure water before heating them. |
