Checking out the What's Hot rubric in the Destination Guide, last night I ended up in the International Spaceflight Museum. Wanting to see more details about the Jet Propulsion Laboratory, I inadvertently teleported there in the middle of a conversation (serves me right, chatting and clicking on things at the same time). Duncan came along, and we had an interesting time looking around.
The ISM sim has been inworld since 2007, as far I could tell, but this has been the first time I've heard of it. One indication of its age are the notecards you receive upon TP, advertizing events supposed to take place some time in 2008. The other clue is its somewhat dated appearance, which must have looked amazing back in '07. In any case, ISM is a fascinating place if you're even remotely interested in the history of space exploration.
The Museum is located on a spacious sim containing lecture halls and a large number of exhibits, some of which are clickable for added features. There are nicely built models of rockets and satellites, also of different NASA facilities.
ISM is present in the virtual world only, run by a non-profit. It's one of the better organized ones, too, with regularly updated presence on Facebook and its own wiki. I'm not sure if there are any lectures taking place there these days (the Events page on wiki does not give any information about the 2015 events yet), but the Museum is definitely a place worth visiting and supporting.
