Yes, there is a theme here. Astronomy pics often take my breath away. Particularly those of Astronomy Picture of the Day. The one shared here is from September 27, 2009.
At about 100 meters from the cargo bay of the space shuttle Challenger, Bruce McCandless II was farther out than anyone had ever been before. Guided by a Manned Maneuvering Unit (MMU), astronaut McCandless, pictured above, was floating free in space. McCandless and fellow NASA astronaut Robert Stewart were the first to experience such an "untethered space walk" during Space Shuttle mission 41-B in 1984. The MMU works by shooting jets of nitrogen and has since been used to help deploy and retrieve satellites. With a mass over 140 kilograms, an MMU is heavy on Earth, but, like everything, is weightless when drifting in orbit. The MMU was replaced with the SAFER backpack propulsion unit.
Beautiful, just beautiful. Certain worthy of greeting me each day as I sign onto my home computer...

Beautiful. And good to see a post from you again!

Ha.
Yeah, these desktop posts are my lifeline.
But I have also learned, after I already knew it, to never apologize for not posting. Who cares, right..?? You were not posting, now you have. End of story.
Well, unless of course, you were abducted by aliens or something exciting like that. ...:minism:...

I love Astronomy picture of the day. It's good to have a little perspective change every so often. Or in your case, every time you look at your computer...
