Encounter with Tiber

This was an interesting read. I enjoyed the Tiberian sections of the story quite a lot as it's a bit of a reverse first contact, where we see from their point of view what happens when they reach Earth and find Stone Age humans. The science and engineering concepts were interesting and always a hallmark of hard sci-fi stories. I found the cast too large for the narrower scope of the story (pretty much everyone is given a name, description, job, etc even if they never get any lines of dialogue) and the plot at times slowed down, but it was otherwise an enjoyable story. It makes me wish humanity was more united in its pursuit of knowledge and of a better tomorrow.

An astronaut's science fiction book.

It is marred in a few places by careless editing that allowed some discontinuities to get into print. A radio signal with a wavelength of 96 meters would require an extensive EVA to construct a full wavelength loop antenna. A signal with a wavelength of 0.96 millimeters is on the border between extremely high frequency radio waves and extremely low frequency infrared light. Not at all the same thing. In any case, a resonant antenna would not be necessary to receive the signals, and a much smaller resonant antenna could be built much more safely.
