The today’s collection of interesting/useful links is: Space Shuttle Endeavour and STS-134
NASA shuttle mission page for STS-134 - Straight from the horse's mouth.
Wiki page on STS-134 - Go down the space program rabbit hole.
STS-134 Official Mission Poster - Nice reference to the latest Star Trek. Galaxy Quest would have been acceptable as well.
Pano of Endeavour on the pad - Warning, this is a java app and it launched itself to the background on my Chrome browser. Had to minimize the main window to see it, but it was well worth it.
I made a trip down to the Cape for the launch attempt of STS-134. It got scrubbed. All part of the launch experience. Heading back down on Sunday to see if they can keep all systems go for launch.
