The Phoenix Lander launched August 4th, 2007 and landed successfully on Mars near it's North Pole on May 25th, 2008. Since then it's been taking images and samples into it's experimental suite of instruments in the NASA "mantra" of "follow the water" in it's Mars exploration on each Mars mission.
So one might wonder, why Phoenix would NOT sample what could be CLEARLY seen as "puddles" forming in the trench dug by the robot arm named "cupboard"?
See images below by Woodlock and a Great Big Thank You for the talent, work and generosity in sharing these images along with the dedication to following the mission so closely and holding NASA's feet to the fire of BRUTAL TRUTH.
Below are the four images Woodlock did as is...see if you can tell the difference over time. After that will come the SAME four images only I ONLY annotated them by drawing a blue circle around LIQUID WATER as is "seeped" into the hole and then froze.
SOL 86 SOL 87 AM

SOL 87 PM SOL 88 leaky

Now if you hadn't noticed the increasing "white stuff" here's the same images with circled areas. Where did this "ice" come from if it wasn't there on SOL 86 ??? Did LIQUID WATER seep up from the ground with the warmth of the sun at the surface level?
SOL 86 no water no ice SOL 87 AM just a little bit starting

SOL 87 PM NOW there's MORE of it ! SOL 88 WOW !! Now there is a LOT of "it" !!!

Now can you see why NASA/JPL/Phoenix did NOT want to "sample" this stuff ???
OMG !!! LIQUID WATER AT THE MARTIAN NORTH POLE !!!
ALL against common "mainstream" thinking about Mars and what NASA has been saying for all these years.
As the saying goes..."Who you going to believe, NASA or my lying eyes"?
From Woodlock to provide route to raw data:
Agreed Bob any question just ask
Some Phoenix links: JPL (mother) no data.

NASA(father) The archive here takes awhile to get the new data posted, weeks,
hard to navigate.

Arizona(boy) The archive here gets new data the soonest, one till thee days.
hard to download data and find photo numbers.

Texas A&M (citizen) The archive is very good. SSI (Surface Stereo Imager) data
only.
