U.S. Space & Rocket Center Rocket Park Aerial Photos
The U.S. Space & Rocket Center's Rocket Park has changed over the years, even since I started visiting. Several rocket engines have been moved indoors, as has the Saturn V. The Titan II has been taken off display. I have photos of these artifacts on this Website, and these artifacts are still visible in the historic Google Earth imagery.
The best-quality aerial imagery on Google Earth showing all of the artifacts in the Rocket Park which were exhibited when I first visited is dated March 30, 2002. I've annotated the locations of the Titan II, Saturn V, Descent Propulsion System (DPS) rocket engine, J-2 rocket engine, NERVA rocket engine, F-1 rocket engine (which is still displayed outdoors), A-7 rocket engine, and V-2 rocket engine:
For the most part, I don't know the dates on which the artifacts were relocated; the best I can do is examine the dates of the last photos I took of the artifact in its old location and the first photo I took in its new location. Of course, I didn't necessarily take photos of the artifacts on every visit, and probably would have only taken new photos when I noticed that they had moved.
I was actually surprised that the V-2 engine was still displayed outdoors as late as my first visit to the USSRC: I don't specifically remember seeing it outdoors and I didn't purposefully photograph it, so I assumed that the aerial imagery above was captured prior to my first visit. However, upon seeing it in the photo above, I looked more closely at some of my old photos of artifacts near the V-2 engine's position, and I did find one such photo from July 2002. By October 2002, the V-2 engine had been removed from the Rocket Park (although part of its stand had not yet been removed), so it's no wonder that I don't remember it being on display outdoors.
The DPS engine was moved indoors sometime between October 2002 and June 2005.
