ENDEAVOR is FREA's quarterly publication. ENDEAVOR tells the story of Dr. Enzmann and his wife Joanna Enzmann - he a world-class geologist, historian, linguist, astronomer, engineer, and physicist, and she a skilled mathematician and programmer who worked on the first computers and some classified projects - and how they worked together to create the skin in which the space program could grow. FREA's quarterly ENDEAVOR includes papers written on topics like gravity, astronomy, geology, physics, time, history, cosmology, and mythology, symbology, mathematics, space mission planning, planetology, and more. Trivia from the Archive will include photos and artwork, and articles about Dr. and Mrs. Enzmann published over the decades.
