Space Travel

Dr. Odenwald has written three books on space travel based on his perspective as an astronomer. See a short FAQ selection at the bottom of this page!


Interstellar Travel:An Astronomer’s Guide,  describes the many astronomical and human-scale issues that make interstellar travel a formidable challenge, even with the right technology for making the actual trip. Since the 1920’s, science fiction authors have invented dozens of ways to make interstellar travel a reality. Sadly, after nearly 100 years of effort, scientists and engineers have yet to invent a single inexpensive technology to get us to the stars. What is more disturbing about this challenge is that the actual technology to make the trip is mostly irrelevant. Some of the issues are already known and being addressed such as: What will be our destination? How many travelers should go? What will happen to human health along the way? But the Big Picture of interstellar travel goes well beyond the design of the engines that power our starships.

The core questions are what they have always been: Where should we go? What will we do there? and How will it benefit folks back on Earth?

Interplanetary Travel: An Astronomer’s Guide, Why is it that 50 years after the official start of the Space Age we do not have colonies on the moon and Mars already? Why are we still plodding along in Earth orbit? There are a million of these kinds of questions you can ask, but when you dig into their answers you uncover something very odd indeed.  In this  book,  we discover that in fact we have all the technology we need to make it happen, but our current problem is we lack dreams.

A Guide to Space Travel from A to B, is a condensed version of the previous two books and covers all of the same issues, though with fewer illustrations to make the cost substantially less! There is also a Kindel version of these books!
