1. Book (1949) written by Willy Ley and illustrated
by Chesley Bonestell, based on material
earlier published in a series of Collier's magazine articles on space
travel (see Collier's Space
Program). It is best known for Bonestell's inspirational paintings, including
16 in full color.
2. Film (1955) directed by George Pal
and partly inspired by Ley and Bonestell's book. In a thematic sense, Conquest
follows on from Pal's Destination
Moon (1950), taking space exploration beyond the Moon to interplanetary
space and, in particular, a manned journey to Mars.
Although the characterization is poor and the dialogue often inane, there
are some memorable scenes, including those of a rocket attempting to outrace
a pursuing asteroid and a wheel-like space
station, designed along the lines proposed by Wernher von
Braun.
