The Prentice-Hall Book About Space Travel / The True Book About Space Travel (1954/1955) PART 2

As promised I have some more space art to share from these books.  For the first post see here:

The art in The True Book about Space Travel had been redone for American publication a year later.
 The first one up is this nice diagram of a manned flight. This is based closely on the British Interplanetary Society's (BIS) plans for a manned ship.

The next is the surface of Mars

Finally the V-2 "bumper" rocket set up that were the only actual rocket tests going on at the time.

Any conclusions to be drawn from these drawings?  Mostly they are interesting to see how two artists interpreted the same scenes.
