Near infrared (750-1000nm), the wavelengths used by Clementine, does not show thermal radiation but it does highlight certain minerals.
Yes, the pattern on the floor of the crater is interesting. The phenomenon is seen on Earth as well as other planets and is caused by the cooling of molten material. In the case of Tycho it is thought that lava filled the floor of the crater and formed the polygonal pattern as it cooled and hardened.
Regular polygons are common in nature. But I wouldn't call the patterns in Tycho "regular".

These UV/VIS images were formed from a mosaic of five image cubes, each consisting of spectral bands (415 nm, 750 nm, 900 nm, 950 nm, and 1000 nm). These data were acquired during orbit 40 on February 28, 1994.

Yes, but the image you show of Tycho is not from the thermal imaging (LWIR) camera!
(For the third time.)
