This picture was an "In Memoriam" for Bruce McCandless, who died just before Christmas, but many in this thread seem to have missed that.
An appreciative obituary appeared today in the UK national newspaper the Gaurdian:

Reminds me that for a few years (a few years ago) at my university we had a Dean who had a horror of black holes. It seemed to come up in every talk she gave.
Well... this is the first time I've mentioned any fear of floating free in space, I think.

I'm not afraid of floating free in space, because I trust the gravity of good ol' Earth not to let go of me!

I think the root of whatever fear I may have of the thought of floating free in space harks back to 1969, when I first saw 2001: A Space Odyssey. One of the astronauts in the ship that is on course for Jupiter falls out, and I realized that he would be falling and falling and falling and falling forever in the black emptiness out there. (Today, of course, I would say that he'd be orbiting the Sun.)

David Bowie's video Blackstar spoke pretty strongly to me. Bowie sang about his own imminent death, and he portrayed himself as a jewel-encrusted cranium inside a space helmet, and as a skeleton falling into the Sun. Those images resonated with me.

(And now, when I watched that video again, the scene with the skeleton falling into the Sun was gone. Well, it was there before.)

Ann... Frank Poole does not "fall" off of the Discovery...he is SHOVED by HAL...his oxygen tube is severed, and he frantically tries to get it reconnected...

And...he does not "fall forever", as Dave Bowman goes out and gets him... so, nothing to fear.....EXCEPT HAL!!!!!

Thanks, Boomer! :D

I was just telling you what my 14-year-old and extremely impressionable self thought of that scene.

Thanks for the info! :D

Awesome.... and when they got back in, the Nitrogen was used to cool a couple of "TALL ONES".... no doubt....

I don't think the astronaut here was in much danger. The dangerous part about space is mainly in getting there and getting back, not being there.
That's horrible enough for me!!!

I would love to float free in space, of course, with the knowledge that I'd easily get back. :)

An amazing photo!

Anyone who really wants to float free in space must either have a death wish, or have imbibed too much!

Of course, the view must be beyond spectacular!

Bruce McCandless II made it to 80. I salute him!

Image To Fly Free in Space

Explanation: What would it be like to fly free in space? At about 100 meters from the cargo bay of the space shuttle Challenger, Bruce McCandless II was living the dream -- floating farther out than anyone had ever been before. Guided by a Manned Maneuvering Unit (MMU), astronaut McCandless, pictured, 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 worked by shooting jets of nitrogen and was 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.
