In my younger days I was involved in the U.N.'s effort at colonization of Jupiter.The nuclear propulsed Aldebaran, a ship that I have spent time on, and will always have a place in my heart.
My good old space propulsion calculator - very handy for in course corrections - I would have been caught dead without it.
One of Von Braun's rockets, I saw one take off and it was a sight I will never forget.
This was a postcard handed out to new recruits, it simplified our space craft as a subway map simplifies the system it seeks to communicate. For instance, I could say " I'll take the space stick and you can watch the televisor for awhile." and they wouldn't get lost in all the technical jargon.
A cut away of the typical Jovian high orbit station, I have also spent extended time periods aboard these ill designed cans. I do not recall anything pleasant about that structure, except for the cut-away artwork that was supposed to represent that malfunctioning tub.
The last image is of the Soviet Jupiter shuttle. Its mission was to transport cargo from the cans, (Jovian orbit space station) to the zeppelins. The flight consisted of a gradual descent through the upper atmosphere of Jupiter; the frantic hunt by coordinates for the zeppelin we were looking for (radio communication is bad to non-existent); and then the landing. If you look closely at the zeppelin you will notice that the landing pad was a little space on top, hair raising!
That's all of the unclassified info I have at this time. Maybe someday soon my entire story can be told.
