Deep Space Flight and Communications: SETI, KLT and Astronautics in a 2009
book -- Dr. Maccone's new technical book about SETI, KLT and space
missions to the Sun gravity focus will be presented in this talk. This
400-page book is entitled "Deep Space Flight and Communications", costs
(unfortunately) over $100, and is divided into two parts: (1) The first
200 pages describe the astrophysics of light-bending caused by the mass of
the Sun. Since the minimal focal distance turns out to lie in between 550
and 1000 AU, any future space mission to exploit this effect must
necessarily be a "deep space mission". These FOCAL space missions are
studied in the book and a Phase A Proposal was submitted by Dr. Maccone to
ESA back in 2000. He now argues that a similar Proposal should be
submitted to NASA. (2) The second part of the book is devoted to the KLT
as optimal telecommunication tool (better than the FFT). The KLT for SETI
was presented by the author in various talks, but, in this book, the
reader will find the relativistic KLT also. This is useful to keep the
radio link between the Earth and any deep-space spacecraft, such as the
FOCAL spacecrafts to 550 AU. Dr. Maccone discovered mathematically that
the relativistic KLT eigenfunctions are Bessel functions of the first
kind, and that the KLT eigenvalues are the zeros of such Bessel functions.
All this paves the way to "Star-Trek-like" relativistic space flights of
the future.
Clear skies!
