Mars Phoenix Lander: Daily repeated change of soil electric permittivity and visible evaporating brine in the ground

The mysterious white stuff suddenly appearing in the Martian soil seen by Phoenix Lander on Mars, active May 2008 - November 2008:

It's interesting how apparently all scientists' research only focuses on the disappearance of the white material after the trench was dug and not how is suddenly gradually appeared a few seconds after digging. This gradually appearing hints to a liquid brine pouring out of the ground and then evaporating increasing the salt concentration. This great video presentation goes into the details, but still ignores the pouring out before freezing: https://www.youtube.com/watch?v=AvHaaLIJqYA
For the electric universe discussion this other detail from the same presentation video is interesting: A sudden daily repeated change of the electric permittivity of the Martian soil during the night. That's measured by 4 needles on the robotic arm pressed into the ground. Temperature was also measured with those needles. Though they had problems with the temperature measurements as the contact to the soil was bad and needed unexpected high pressure from the arm to achieve usable measurements. I'm still a bit sceptic about the temperature measurements as they are surprisingly close to the atmosphere temperature also measured by the lander. With the sun shining on the ground it should be noticeable higher in the almost vacuum atmosphere.
In article Formation and Persistence of Brine on Mars: Experimental Simulations, section 3.2 goes into that direction with an interesting lab experiment but also ignores the pouring out before freezing: https://www.liebertpub.com/doi/full/10. ... .2016.1525

As visible in this new animation by user landru79 the white material appeared within a few seconds after digging! https://twitter.com/landru79/status/1762579331505627405
