Chesley Bonestell and the Landscape of the Moon

Chesley Bonestall's Conquest of Space (1949).
Paul D. Spudis
The Once and Future Moon
Smithsonian Air & Space

The influence of the arts on our popular culture is well known. The television generation grew up with Forbidden Planet and Star Trek, shaping our sensibilities and expectations about space travel.  The genre of “space art” enlightened and expanded our minds and ignited our imaginations.  The sixties and seventies brought us  “space” artists with their startlingly realistic vistas of unvisited worlds and ancient times.  Authors, writing for all ages and levels of interest, found eager audiences.  From the beginning, the space age left an indelible mark on many.

The spiritual father of these efforts was an artist from the earlier half of the century.  Renowned for what was called “astronomical art,” Chesley Bonestell (1888-1986) painted some of the most famous and classic works of space art.  His sequence showing the ringed giant planet Saturn from its various moons inspired hundreds of students to take up math and science.  Bonestell loved painting the planets because he was convinced that we would soon be visiting them.  His artwork was used to illustrate what media described and popularized about the forthcoming age of planetary exploration.

Bonestell made great efforts to get the technical details of his paintings correct.  He read the scientific literature so that his planetary landscapes reflected the most current knowledge of how his imagined scenes might really appear.  One of his classic pieces of work was for the influential film Destination Moon, produced in 1950 and based on stories by the classic science-fiction writer Robert Heinlein.  Bonestell did matte paintings for the Earth departure and lunar approach scenes.  His masterpiece in that effort was a fourteen-foot long, full panoramic view of the surface used during the lunar stay scenes in the movie.

Bonestell reminded his audience that our home planet is nearby — the backyard of near-Earth space.  Earth hangs relatively low in the sky over the horizon of the crater Harpalus in Mare Frigoris (latitude 52°N); rough jagged peaks, starkly lit by unfiltered blazing sunlight, are set sharply against a black sky holding a sea of silent, non-twinkling stars.  The demands of film intruded onto his artistic vision through the addition of giant cracks on the surface, a modification to which Bonestell objected.  The producer, George Pal, needed the surface cracks so that he could starkly illustrate perspective, as nearby human-scale cracks would rapidly fade into smaller ones in the distance.  Bonestell wanted to show just a dusty surface, a far-field contrast that would have been difficult to portray on the screen.

It is in regard to his portrayal of the mountains of the Moon that Bonestell has received, if not criticism, at least light censure (not without some slightly smug condescension) from some scientists.  He painted a lunar landscape ringed with rough, jagged peaks, towering about the plains, similar to the barren landscape of Death Valley in his native California.  In part, this was the conventional portrayal of lunar mountains; drawings made by engineer/astronomer James Nasmyth in the 19th Century likewise show jagged mountains on the Moon.  Telescopic views leave this impression, based largely on the dramatic appearance of sharp cast shadows on the lunar surface, visible at low sun elevations as shadows of the ringed mountains of the mare basins extend hundreds of kilometers across the flat plains of the dark maria.

The remarkable smoothness of the lunar mountains was evident when Apollo 15 went to the Moon in 1971.  To the disappointment of many, Bonestell’s vision of rugged, craggy peaks (blindingly illuminated by early morning sunlight in the black sky) gave way to an undramatic,  smooth, undulating terrain, so bland that it was difficult to gain any perspective on distance.  The sense of letdown among space buffs was widespread and illustrated most dramatically in a 1990 painting by David Hardy entitled The Way It Should Have Been, which paid tribute to Bonestell’s now-obsolete vision of lunar vistas by showing an Apollo Lunar Module snugly parked amidst the craggy peaks of Bonestell’s old Moon.

More of the Moon’s physical appearance has been unveiled.  The recent fleet of spacecraft that orbited the Moon has shown us dramatic vistas never before seen.  The spectacular high-definition television of Japan’s Kaguya spacecraft (by the way, when will NHK release a Blu-ray video disk of all that magnificent footage?) displays awesome landscapes that slowly drift beneath the orbiting vehicle, and NASA’s Lunar Reconnaissance Orbiter Camera system has provided some unique and remarkable views.  Some of the most dramatic are oblique-looking perspective views of famous lunar landmarks.  An oblique panorama of the floor of Tycho, the prominent rayed crater on the lunar near side, shows its magnificent, rugged central peak rising out of the inky darkness of the early lunar morning.  That description sounds familiar, doesn’t it?  In fact, when I first saw the new Tycho oblique, I seemed to recall a specific Bonestell painting that was very similar to it.  It was one that Bonestell did for an early 1960’s book, Rocket to the Moon.  The distant peak in Bonestell’s painting eerily foreshadows the dramatic LROC image by 50 years.

Chesley Bonestell’s Moon lives!  Fresh, uneroded features there are as sharp and dramatic as he portrayed them half a century ago.  As lunar features slowly erode under constant sandblasting by micrometeorites and downslope movement of debris, they become smooth and rounded.  The Apennine mountains at the Apollo 15 landing site are smooth because they formed almost 4 billion years ago, in the early dawn of lunar evolution.  In contrast, the central peaks of Tycho were thrust up a mere 100 million years ago, a blink of the eye in lunar geologic terms.  In a couple of billion years, it too will round off and mellow, a gentle undulation on the floor of a nearly obliterated crater.

“The Way It Should Have Been?”  Nah – the way it really is.  On the Moon, as on Earth, spectacular landscapes feed the human spirit and kindle our desire to travel to new places.

LOLA's Sea of Crises



NASA GSFC - Located in the northeast quadrant of the lunar near side, Mare Crisium is a Nectarian aged basin that spans 740 km. LOLA data reveal that the floor of Mare Crisium is approximately 1.8 km below lunar datum, or "sea level," the Moon's global average elevation - while the outer rim is about 3.34 km above lunar datum.

Lava flow features are prominent enough in this mare that they can be seen in the LOLA topographic data (see arrows in image for locations of some of these features).

Two Soviet missions landed in Mare Crisium in the 1960's and 70's. Luna 24 landed in Mare Crisium in 1976 and returned samples from the lunar surface to Earth.


Brighter shades represent higher elevations in this early release of LOLA data showing the outer rings of the ancient impact. Palus Somni and the rays of Proclus on the basin's western extremes, so familiar to observers on Earth, are not so distinct in this digital elevation model [NASA/GSFC/MIT].

Luna 24's predecessor, Luna 15, was less successful. It crash-landed in Mare Crisium in 1969.

Mare Crisium is also the location of Luna City - a fictional city featured in the book "The Moon is a Harsh Mistress."

Where is Harriman when we need him?



Wayne Hale
NASA Blogs

During my childhood, back in ancient times, science fiction was my reading material of choice. Isaac Asimov, Arthur C. Clark and Robert Heinlein were first among the pantheon of science fiction writers in those days.

One of the best was Robert A. Heinlein's 1949 story "The Man who Sold the Moon". A brilliant American businessman (today we would say entrepreneur, then Heinlien called him a robber baron) devoted his vast wealth to building a moon rocket. Think Elon Musk but with Bill Gate's fortune and Donald Trump's ethics. Of course he succeeded, despite of all the difficulties, including the roadblocks set up by the government. At the end of the story Harriman famously tells his best friend: "I would cheat, lie, steal, beg, bribe -- do anything to accomplish what we have accomplished".

Where is Delos D. Harriman today? We sure could use him. "We" being all those folks who really really really want to humanity off this planet in a significant way. And maybe not depending on the vagaries of politics and politicians.

This Reborn Passion for the Moon

Some preliminary thoughts have come to mind, admittedly from quite a distance from the 3rd Space Exploration Conference in Denver, about Goldstone's radar survey and what NASA has revealed today about the region inside 5 degrees of the Lunar South Pole, particularly what we now appear to know with increased certainty about the elevations and general topography of that historic region.

It may be a little difficult to think of a previously obscure and unvisited spot in the Earth-Moon system as historic. Perhaps we should think of the Prospector impact point as essential to "Future-History," and no longer the realm of Science Fiction masters like Robert Heinlein.

Long ago, back in 1999 when Prospector and its neutron spectrometer showed a definitive signature of Hydrogen around the lunar poles no one was more tickled than I. Some of us have been literally anxious for a reawakening of interest in our Moon since December 1972 and the bittersweet success of Apollo 17. A possible presence of water slurry somewhere on the Moon might be just the thing, and indeed it has been, cinching the deal and making our return inevitable whether those, perhaps not so ancient, cometary remnants prove to amount to much or not, and quite possibly with or without the leave of governments and taxpayers.

Since then, it's been shown water can be refined from the lunar surface and perhaps just about anywhere on the Moon. The obvious positioning of our relatively large natural satellite as a kind of pier, a site for rail guns and materials and astronomy, with no ecological worries, no EIS responsibilities and all the rest some of us deducted and lobbied for over the past 35 years is more generally known then ever before or since.

It's a relief, really, no longer having to have to explain these things, over and over. And if you can give credit to such simple probes as Clementine and Prospector, catalysed by the horror of Columbia tearing the cover off the rudderless administrative inertia of NASA, so much the better.

In 1999 the presence of water on the moon, I believed. would be the Discovery of the Year, and I still do. The object at rest has been set into motion, harder now to stop than it was to start.

One way to tell how very much interest in space exploration has grown in the short time since is how the news of that "discovery" was received in 1999 and then to speculate on how such news would be received today. I suppose it's a chicken and the egg thing, possibly, whether the "Vision" following Columbia or the possible detection of water or something else entirely has stimulated this passion for the Moon, we've been waiting for these radar studies and the passion for the challenge of a return to the Moon, for plain and practical reasons and by all sorts of people for a long, long time.

In 1999, no one was discussing traffic control problems in lunar orbit or how to set that first flag back up at Tranquillity Base, according to Edwin Aldrin blown over by the Apollo 11 Lunar Module ascent stage - without disturbing those first foot prints. In 2008, were already counting the months until the next probe, the first private probe, the next nation's manned return and where and when the United States will return to this new world, this time to stay.

Once again, "the clock has started."

Nevertheless, with these new radar studies showing us 100 fold clearer detail of a part of the Earth - Moon system never before seen, the Lunar South Pole is better known by the space community than ever before.
