A small magazine article from 1963 describing and depicting a MOL-like “space lab” equipped with a SNAP 2 nuclear reactor. This would have provided something along the lines of 3 kilowatts, plus an added bonus radiation environment. As show in the art, the reactor would be separated from the lab by a fairly long extendable rod, provided a reduction in radiation flux. The reactor would be the small object at far left; immediately next to it would be the “shadow shield,” typically made of tungsten (to stop gamma rays) and lithium hydride (to stop neutrons). This conical frustum is typically the most massive part of space reactors like this, and was used to shield a relatively small conical region, in this case centered on the space laboratory. If someone were to do a  space walk from the lab and drift too far away to the side, entertaining things could well be done to their DNA. Extending beyond the shadow shield is a black cone, the thermal radiator for the system. Contained within the radiator would be tanks of mercury, pumps and turbogenerators; liquid sodium metal would flow through the reactor then through a heat exchanger, boiling the mercury. The mercury vapor would then either directly flow through the radiator, being cooled back to liquid, or through a heat exchanger, some other fluid being passed through the radiator.

Numerous ideas were floated through the mid 1960’s for attaching reactors such as this to MOL-like space labs. The main problem with this was that these labs were typically planned for only a single use; in that case, hydrogen/oxygen fuel cells or solar panels would almost always make more economic and mass budget sense.

Three Radial Module Space Station

Around 1963-64 a fair amount of effort went into the concept of a single-launch space station with artificial gravity. These stations would be launched atop a Saturn V and would deploy either toroidal or radial structures for the crew to inhabit. The design below (probably Lockheed) is reasonably representative of the radial-arm configuration. During launch the three arms would fold down “behind” the station core, and would deploy out 90 degrees once in orbit.

Space Station concept art

Two pieces of NASA-marked (but likely not NASA-produced) concept art from the 1960’s depicted artificial-G space stations.

 

The first station (previously presented here in black and white not so long ago) depicts a substantial three-armed station witha  multi-segment spine and three habitats. At one end of the spine is a nuclear reactor and its radiator; at the other end is a presumably rotationally0decoupled docking section. There is also an external “track” with two cars seemingly to provide transport from one habitat to another; it doesn’t really seem like this would provide a substantial improvement in transport over simply taking an elevator from one hab up to the spine and then down another elevator to the destination hab.

This space station, which appears from the art style to be a Grumman design, is a single-launch space station to be launched atop a Saturn V. The two arms would fold back for storage on the launch vehicle and would deploy once in orbit. An Apollo CSM is shown approaching for docking along the centerline; it’s not clear if the docking cone was rotationally decoupled. if it was not, the two Apollo-like capsules hanging off the sides of the cone are a bit of a head scratcher.

Both renderings have been uploaded in their full resolution to the 2019-01 APR Extras dropbox folder. This folder is available to APR Patreon Patrons and APR Monthly Historical Documents Program subscribers at the $4 per month level and above.

Northrop artificial-g space station art

A piece of concept art circa 1960 depicting a Northrop concept for a space station. Not much to say about it as there are no good scale references, nor do I think I have anything else depicting the station. It is, however, not dissimilar from a lot of other space station concepts of the time… replace the four “habitat” cylinders with a single torus, and this would be pretty much every space station from the Colliers series until the Manned Orbital Space Station concept from the early 60’s.

Shuttle-C art

The Shuttle-C of the late 80’s/early 90’s would have carried a whole lot more to orbit than the Shuttle Orbiter, but would not have been quite as capable of precise maneuvering as the Orbiter. Consequently, it might get close to a space station, but it would be unlikely to dock with it unless it was moved into position with secondary orbital maneuvering vehicles or grabbed with manipulator arms. This artwork depicts a Shuttle-C standing off some distance from a space station, with the cargo being shuttled over with an OMV.

The Shuttle-C was described and illustrated in US Launch Vehicle Projects #4.

Maintenance Station in Space

A piece of art from 1962 depicting a Westinghouse Electric Corp. concept for a space station meant to provide servicing for nuclear powered spacecraft. it appears to be more of a space craft than a space station, since it is equipped with a substantial nuclear propulsion system of its own. It’s unclear what the set of rings at the “front” of the space station are meant to do.

Rotating space station art

An artists concept of a rotating space station circa 1962. It has a NASA ID number but it *may* be North American Aviation, as they designed a space station essentially identical to this, as described and illustrated in an article written by Dennis R. Jenkins for Aerospace Projects Review issue V1N6. This space station was designed to be launched as a single payload atop a two-stage Saturn V; it would unfold once in orbit to form the pseudo-toroidal shape. This piece of art depicts a central docking hub that must have been intended to be rotationally decoupled from the station. The space station must have been non-rotating at the point in time illustrated, or those spacewalking astronauts are going to have an interesting time doing their job.

A high-rez scan of this piece of art has been uploaded to the 2018-08 APR Extras folder on Dropbox for APR Patreon patrons at the $4 level and above. If this sort of thing is of interest, please consider signing up for the APR Patreon.
