(Inspired by this question)

One of the distinguishing features of Shuttle Columbia was its Shuttle Infrared Leeside Temperature Sensing (SILTS) pod. This was an experiment that took infrared imagery of the left wing and parts of the fuselage during entry. (It was deactivated long before the STS-107 accident so there was no data from it contributing to the accident investigation.)

enter image description here

Is there any imagery from this experiment available online? I found this paper (warning, pdf) that uses some results, but no actual imagery.


1 Answer 1


Wikipedia has one image that is attributed to the SILTS pod:



Unfortunately, the metadata doesn't give any clue as to where it came from, or where more might be found.

I just happened to be reading the STS-28 page, noticed the image, and remembered this question.

    $\begingroup$ While it appears as of the right-most "hot spot" is the leading edge of the port wing, one one wonders what caused the left-most such "hot spot." $\endgroup$

    $\begingroup$ That is the gap between the inboard and outboard elevons. $\endgroup$ Commented Dec 19, 2016 at 18:28
