NASA's Small Business Industry and Advocate awards will be presented on the symposium's second day.
Over the next several weeks, four survival heaters will be shut down, one at a time, in an effort to conserve power.
Shutting down this heater is expected to save 250 watt-hours of power per Martian day.
The thermal and electrical-conductivity probe (TECP), located on the wrist of the arm, has been inserted into the soil and will continue to measure soil temperature and conductivity, along with atmospheric humidity near the surface.
The unit hasn't been used since landing, and disabling its heater is expected to add four to five days to the mission's lifetime.
