TEGA High-Temp Soil (TA7_plugged) DAY 2

Reconciled with block: tega_sporty_ht_ramp_ta7_2 Objectives:

Power on and perform Day-2 of a full high-temperature ramp on the sample in TA7, which has been previously heated via midday-1 High-temperature ramp. This sample had a plugged frit during the low and mid-T runs, and is assumed to be plugged here. The purpose of this run is to provide a baseline for the enthalpy associated with decomposition of altered minerals found on Day-1 and to provide a baseline for the gases given off by the decompositions. We are flowing no carrier gas, so the calling block will be identical to the Day-1 block except that the TA Sample valve is left closed throughout the run.

Configuration:

High-temperature Day-1 ramp has been completed previously. The carrier valve is closed and the TA manifold has no gas in it. It was emptied during the Day-1 procedure. The carrier valve will not be operated due to its erratic behavior. Software updates were made post Sol 113 to the 386SW and the mode table was changed to V125
