The article has a link (citation 17) to a site selling toy models of that vehicle as an image source, I can find one (fourth image in the gallery) there where it sorta looks like the wing is missing because the wing is black against a black background but it's not the same image shown in the paper:

The name "Venturestar" is properly rendered in that image but "NASA" and "Lockheed Martin" are thoroughly mangled the way I'd expect text to be mangled in an AI image. The image from the toy site could have been used as as reference image to create the image in the paper one way or another.
