So a large change for today, instead of Outer Space books we are going to Inner Space with Undersea Base. I have blogged about Mae Freeman's book Space Base (1974) several times. In it she showed children visiting a space station in the future.  I recently found she had also written a children's book about futurist undersea exploration and children visiting an undersea base in the future. The late 60s and early 70s had an optimism about what might happen in the future and that shows in this lovely book. As a child of that time I remember being a big space flight fan and thinking about living in space as an astronaut and I also had dreams of living under the sea as an aquanaut. Freeman, Mae.
