You know it’s important.  I know it’s important. Coffee on Mars.

The first batch of coffee started in MMS-1 simulant died, almost immediately.  Now we have MMS-2, a new updated version that is 92% chemically similar superfine regolith simulant, and a second type made in the Exolith Lab at UCF in collaboration with NASA-KSC, MGS-1 that is minerologically identical to Rover samples analyzed by laser ablation and X-Ray spectroscopy.

We are beginning in MMS-2 that has been in our freezer for 8 weeks. We want to make sure all insects, eggs, or bugs are deceased before transplant.

We transplanted today in typical Seattle weather.  So far so, good. Not dead yet!  These plants will be our controls. To be grown in Earth atmosphere, 760 Torr.  Nothing fancy except the transplanting and the soils.
