#79 — Don Davis: Space Art & Humanity's Future
Brief
Don Davis (Speaker 2), a veteran space artist, traces his vocation to childhood experiences of the space age — starting with Sputnik in October 1957 — and to an early job at the U.S. Geological Survey’s Menlo Park office in November 1968. At USGS he moved from hand‑coloring geologic maps to painting scientifically informed reconstructions of the Moon’s ancient appearance under lunar geologist Don Wilhelms; those reconstructions ran in Icarus and became reference visuals that shifted space art from speculative to data‑driven as lunar orbiter photos, Apollo imagery and Mariner 9 for Mars supplied real topography. Davis recounted meeting Carl Sagan (via Paul Fox) and how a Mariner‑based Mars painting helped Sagan appreciate his work; some of Davis’s lunar sequences later appeared on Cosmos despite format awkwardness (Speaker 2). He places artists like Chesley Bonestell and Lucien Rudaux in historical context, explaining how telescopic contrast and vertical exaggeration shaped early, now‑outdated depictions.
The conversation then moves to Davis’s role in the 1970s space‑colony movement: two of his space‑habitat paintings appeared in L5 Society publications, and his San Francisco‑Bay‑in‑a‑colony image — a lush, bridge‑and‑creek interior intended to highlight ecological challenges of closed systems — became especially influential; the original oil is missing and he is preparing a new, wider‑angle version. Davis urged that the biggest technical barrier to large habitats is ecological knowledge (how to transplant and sustain Earth ecosystems in smaller volumes), not solely rocketry. On launches he noted positive iterative progress in SpaceX Starship tests, cautioned that SLS launches are too rare to sustain momentum, and identified about $100/kg as an approximate cost threshold for broad space activity. He also cited cultural touchstones (2001, Bradbury, Willy Ley, Things to Come) as important to inspiring publics. The host and Davis agreed throughout on the central role of visualization — paintings, planetarium shows, VR — to convert technical proposals into emotionally compelling futures; Davis closed by rejecting the ‘‘no Planet B’’ argument, saying humanity will have to build its own Planet B and that limiting human potential is a view future generations will judge harshly.
Why it matters
Don Davis (Speaker 2) remembers his first space-age news event as Sputnik on October 4, 1957, and says that childhood exposure shaped his lifelong career in space art.
Key details
- Davis was hired at the U.S. Geological Survey (Menlo Park) in November 1968 to hand-color geologic lunar maps and then to paint reconstructions of the Moon’s appearance in earlier geologic eras for Don Wilhelms; those reconstructions were published in the journal Icarus (Speaker 2).
- A Mariner 9–informed painting of Mars that Davis brought to a gathering (by Paul Fox) impressed Carl Sagan, who later used some of Davis’s lunar history paintings in the TV series Cosmos (Speaker 2).
- Davis created influential space‑colony paintings for the L5 movement in the mid-1970s (published in L5 News); his famous San Francisco‑Bay‑style interior colony painting is widely circulated in prints but the original oil painting is lost and Davis is producing a new, wider‑angle version (Speaker 2).
- On technical feasibility, Davis argued that lowering launch cost toward roughly $100 per kilogram (he spoke in metric) is a key benchmark for making large-scale space settlement and passenger activity viable; he contrasted reusable rockets (e.g., SpaceX Starship’s iterative testing) with NASA’s heavy SLS launches, which he called too infrequent to create Apollo‑era momentum (Speaker 2).
- Davis emphasized that the hardest problem for space habitats is ecological — learning to sustain closed ecosystems in small, transplanted 'terraria' — and argued visualization (illustration, planetarium shows, VR) is essential to making those concepts comprehensible and galvanizing public support (Speaker 2).
