I'm not sure, but it may be because a mod is inactive or unworkable with the current KSP build. I have on that needs to be updated (Firespitter) and I had that screen for the first time today. By far my favorite bit is the random Kerbal all up in the camera's face. Sadly this entire "faked mun landing" was itself just a fake. KSP mission directors had planned to use filmed footage because Jebediah's design stipulation for "MOAR BOOSTERS!" would have delayed the project indefinitely for lack of funds. Jebediah, ignoring KSP's official position that a kerballed launch would be suicide and doomed to failure absconded from the guarded film stage with his crew and went ahead with the real mission to the mun anyways. His piloting prowess unmatched, he landed the CSM nosefirst into the munar surface. Jebediah & Co's fate is currently unknown (prominent theories as to their whereabouts vary from "they settled down and took up root in a cave" to "planning an epic EVA return voyage to the Kerbal Space Station. George Klooney has been flown there just in case they run out of EVA propellant as they approach the station's large solar panel arrays.
