that way the wtf shadow does not interfere with hb cube measurement and the hammering does not troubleise, even though we will use it for some cool measurements because we're generating a seismic signal. once hb cubed is safely on the grund, we make sure it is in a good location and release the mole to the surface so it can begin the penetration phase. what does it look like? the mole hammering peck nix, it is like a long nail with a hammer inside of it, which saves time. so there is a motor here what is going to spin a weight and lift it up, and as it lifts the weight, it is actually compressing a spring above it, and then the spring pushes that weight down really rapidly, and hits the tip, and moves it slightly into the ground with every strike. so it is slowly hammering its way in. and there is actually a spring at the top that absorbs some of the recoil so it doesn't just bounce in place. as we go down, we will go about 50 centimeters at a time and pause and let the soil cool off for a pew days and do a thefrmle conductivity measurement. and then move on. because once we've left on
