One of a series of Martin Marietta promotional artworks depicting the utility & versatility of the Manned Maneuvering Unit (MMU), manufactured by them. Here, an astronaut is servicing/repairing what appears to be a/the Large Space Telescope (LST), also/later-known as the Hubble Space Telescope (HST).
Note the interesting foot restraint configuration, either incorporated onto the exterior surface of the LST/HST, or possibly affixed to a mounting fixture on the satellite. And, apparently, no tools required…at least not in this instance…just a swap-out. 😉

One of many beautiful works by Charles O. Bennett.

A stunning & creative/imaginative depiction of what looks to be servicing/maintenance of the Long Duration Exposure Facility (LDEF) during an Extravehicular Activity (EVA) performed by two Manned Maneuvering Unit (MMU)-clad Astronauts.
Note the two 'appendages'/rods extending out/forward from the MMU worn by the astronaut on the left. One of them appears to be attached to/grasping(?) the LDEF tray/panel, at a point where the Astronaut is also grasping the tray/panel. I wonder if they're used to "hold" the tray/panel during transit to/from the LDEF & orbiter. So, maybe it was just delivered, or about to be returned to the orbiter. I have no idea if the changeout of exposed sample trays/panels was ever a planned LDEF maintenance activity.

Then again, and bear with me, based on its color, Florida looks to be uncharacteristically arid. So, maybe this is some sort of diabolical orbital desiccant ray weapon being serviced by SPECTRE agents. I mean, it is sort of ‘pointed’ right at the state.

Fortunately, the top tips of some of the letters of the artist’s signature survived the cropping of the image, revealing the artist to be Martin Marietta’s irrepressible Charles O. Bennett. As such, this scene is meant to promote the utility/virtues of the MMU.

And, going against my urge for “right” geographical orientation, especially with something as obvious as the Florida peninsula, the image is oriented as Mr. Bennett intended.
Finally, a rather exaggerated Cape Canaveral can be seen between the LDEF & left armrest of the MMU on the left.

Continue to Rest In Peace Good Sir, and thank you:

“Views taken of Astronaut Bruce McCandless as he maneuvers in the Manned Maneuvering Unit (MMU) around the cargo bay.”

The above & image at/from:

Note that the photograph was obviously taken during orbital “night”. Additionally, McCandless is flying MMU no. 2, which, based on the cursorily documented footage I’ve come across, suggests this to be EVA no. 2. It was during this EVA that McCandless tested Trunion Pin Attachment Device (TPAD) operations. However, the TPAD is not attached at this point, so if this is indeed from EVA no. 2, I assume it’s either at the beginning or end of it. Or not. Regardless, it’s a super rare kick-ass photograph.

“Astronaut Robert Stewart moves back to the shuttle Challenger after moving out to a distance of about 300 feet wearing a Manned Maneuvering Unit (MMU) during his Extravehicular Activity (EVA). His face is clearly visible as he moves by the aft flight deck windows.”

Above paraphrased from/at the following:

Stewart is flying MMU no. 3.

How 'bout that?! A fellow Soldier flying the MMU, second only to Bruce McCandless...a "naval aviator".
Take THAT USAF zoomies…HAH & HOOAH! 😉👍

“Bruce McCandless practices with the trunnion pin attachment device (TPAD) and manned maneuvering unit (MMU) docking with the shuttle pallet satellite (SPAS-01A).”

Also & better, from other photos (linked to below) of the same activity:

“Close-up view of Astronaut Bruce McCandless II, STS 41-B Mission Specialist, as he performs a test involving the Trunion Pin Attachment Device (TPAD) he carries and the Shuttle Pallet Satellite (SPAS-01A) in front of him. In this photo, he is about to attach the TPAD to the SPAS-01A. He is wearing one of the experimental Manned Maneuvering Units (MMU) developed for this mission.”

And/or:

“Astronaut Bruce McCandless, using the Manned Maneuvering Unit (MMU) in its first flight tests, prepares to perform a docking maneuver during flight 41-B of the Space Shuttle Challenger. Using a docking adapter called a TPAD (Trunion Pin Attachment Device), McCandless docked with a pin on the Shuttle pallet satellite. This procedure was a rehearsal for the upcoming Solar Max repair mission.”

If it were ‘properly’ oriented, that is, from the perspective of the shuttle flight deck, from which/where the photograph I assume was taken, McCandless should be facing ‘downward’. However, this rarely seen image is so damned cool, I chose to orient it in a more familiar/comfortable perspective, to better take in its multitude of coolness.

The insect-like ‘antennae’:

Note also the "flat-top" appearance of McCandless' helmet, due to it actually being the housing of the solid state color TV camera...attached to the top of the helmet. The camera was manufactured by Fairchild Weston Systems Inc., of Syosset, N.Y.
Finally, note the "EV1" labeling of the carabiner just above McCandless' left forearm & whatever is just below his right forearm. Apparently, during the EVAs, McCandless' call-sign during air-to-ground transmissions was "EV-1" & Stewart’s was "EV-2." How that translates to labeling of equipment - I don't know. Maybe they were individually configured/adjusted for ease/convenience of use by the respective Astronaut.

The two pointless observations above are from the following informative document:

“This drawing, looking over the shoulder of command pilot Walter Schirra, shows approach of the Apollo 7 module and its third stage booster in rendezvous exercise. Sighting device is lighted reticle projected on window by instrument above.”

The 'instrument' is the Crewman Optical Alignment Sight (COAS). Interestingly, very little is available, both in images & text, pertaining to the one used within the Command Module. Understandably, the analogous COAS used inside the Lunar Module is by far more 'popular'.

Despite being really into Apollo photos, I'm not all that familiar with the CM's instrument panel(s), however; the depiction appears to be pseudo-accurate, albeit greatly simplified.

Fortunately, yet another unique, creative & unexpected Arasmith find.

Thank You Sir, Continue to Rest In Peace.

“An astronaut enters the cargo bay of the Space Shuttle in this artist’s concept. The large white ball is an emergency rescue unit with another astronaut inside. The man carrying the rescue unit is also wearing a backpack maneuvering unit, currently being designed and built by Martin Marietta Aerospace at its space center near Denver, Colorado. The versatile backpack has many uses, including rescue operations.”

I don't think they would've used the side hatch for ingress, as depicted. I'm pretty sure it didn't have an airlock, and I don't think the entire crew compartment was designed for depressurization/re-pressurization. Great/dramatic visual nonetheless!

Also, per the always excellent Aerospace Projects Review website:

“A 1978 NASA artists impression depicting a “rescue ball” being used. This short-lived product was basically a space suit in spherical form, one that a Shuttle astronaut in shirt sleeves could enter relatively quickly in the event of an on-orbit disaster. Another Shuttle could send astronauts to collect the encapsulated and helpless astronauts and transfer them to a non-doomed shuttle. It was *kind* of a good idea, but once it was realized that the Shuttle takes *weeks* to prep for launch, the idea of using a Shuttle to rescue another Shuttle fell by the wayside. Instead of the crew of a stricken Shuttle relying on another Shuttle for rescue, official policy became la-la-la-I-can’t-hear-you and orbital rescue equipment became superfluous.”

1980…a female American Astronaut had yet to fly in space. Three more years until that would occur:
