Soil Science in Outer Space

In 2007, METER scientists developed a Thermal and Electrical Conductivity Probe (TECP) probe for NASA’s Phoenix Scout Mission, which landed on Mars May 25, 2008. The solar-powered lander collected data for five months until the sunlight waned, ice took over, and communication ceased.

Choosing the Right Water Potential Sensor in 2023

If you’re not measuring water potential, or not measuring it correctly, your data could be telling you the wrong thing. Water content measurements can only tell you so much, and inferring water potential from water content is inaccurate at best, and completely misleading in worst-case scenarios.
