Space missions to the Sun’s gravity focus (550 to 1,000 AU) -- So much gain at 550 AU -- Scientific investigations along the way to 550 AU -- Magnifying the nearby stellar systems -- Astrodynamics to exit the solar system at the highest speed -- SETI and the FOCAL space mission -- GL-SETI (gravitational lensing SETI): Receiving far ETI signals focused by the gravity of other stars -- The gravitational lenses of Alpha Centauri A, B, C and of Barnard’s Star -- The Coronal Plasma “pushing” the focus of the gravity + plasma lens far beyond 550 AU -- NASA’s Interstellar Probe (ISP:2010–2070?) and the Cosmic Microwave Background (CMB) -- KLT-optimized telecommunications -- A simple introduction to the KLT (Karhunen—Loève Transform) -- KLT of radio signals from relativistic spaceships in uniform and decelerated motion -- KLT of radio signals from relativistic spaceships in hyperbolic motion -- KLT of radio signals from relativistic spaceships in arbitrary motion -- Genetics aboard relativistic spaceships.
The majority of books dealing with prospects for interstellar flight tackle the problem of the propulsion systems that will be needed to send a craft on an interstellar trajectory. The proposed book looks at two other, equally important aspects of such space missions, and each forms half of this two part book. Part 1 looks at the ways in which it is possible to exploit the focusing effect of the Sun as a gravitational lens for scientific missions to distances of 550 AU and beyond into interstellar space. The author explains the mechanism of the Sun as a gravitational lens, the scientific investigations which may be carried out along the way to a distance of 550 AU (and at the 550 AU sphere itself), the requirements for exiting the Solar System at the highest speed and a range of project ideas for missions entering interstellar space. Part 2 of the book deals with the problems of communicating between an interstellar spaceship and the Earth, especially at very high speeds. Here the author assesses a range of m
