Alien warnings embedded in our crop circles have gone unnoticed, until now. Governments around the globe race against time to evacuate billions of inhabitants from the planet due to the discovery that Earth will be destroyed in the year 2012, a mere eight years away. Where would we go? How would we get there? Who would be left behind? And why is one race of aliens plotting to keep us here? These are just a few of the questions and obstacles faced on this galactic odyssey by our trio of heroes in Escape 2 Earth. Matt, Will, and Art are reluctantly drawn into an adventure by a secret alien organization that will unlock the mysteries of Stonehenge, the White Pyramid of China, the Mayan calendar, and the Great Sphinx in a scramble to help save the human race. This epic quest for Earth's survival takes you from the powdery pink morning skies on the planet Lazon to the subterranean cities under planet Vada and the Whistling forest. The battle between good and evil that began long ago in a far off galaxy is now being played out with the survival of mankind at stake. This sci-fi story is laced with a touch of telepathy, deception, and a murder or two. Discover the hidden alien base deep in the dark murky depths of the Marinas Trench, watch as the aliens prepare to celebrate at the Festival of Life. Who will survive the race to escape this doomed planet? It is anybody's guess. Who will Escape to Earth?

A simple family of indirect-transfer trajectories between circular orbits is used to evaluate the mass ratio required to complete round-trip interplanetary missions using low-thrust propulsion systems. These trajectories, although not optimum, yielded very substantial reductions in total round-trip time for Mars missions with moderate increases in initial weight. For a powerplant specific weight [alpha] of 10 pounds per kilowatt of jet power, trip times were reduced from 1200 to 600 days, for a typical manned mission, with an initial weight increase of a factor of two. Comparison with a nuclear rocket with 1000-second specific impulse indicated that the electric-propulsion system required less initial weight for trip times as low as 550 days with [alpha]=10 and as low at 400 days with [alpha]=5 pounds per kilowatt. Further weight reductions would be expected with more nearly optimum trajectories.

A brief comparison is made between opposition class (with three impulse return), conjunction class, Venus swing-by to Mars and Mars-Venus double stopover trajectories. Vehicle configurations based on NERVA-I engines of varying life and restart capability are considered. It is found that the opposition and Venus swingby trajectories to Mars yield competitive mission performance; the double stopover entails about 30-percent penalties in initial mass and trip time; and that the minimum-weight vehicle uses a single, restartable engine.

In this and a following issue (Vol. VIII, 1962, Fasc. 2-3) of "Astronautica Acta" there will appear the papers presented at the first international symposium sponsored by the International Academy of Astronautics of the International Astronautical Federation. The theme of the meeting was "Space Flight and Re-Entry Trajectories." It was held at Louveciennes outside of Paris on June 19-21, 1961. Sixteen papers by authors from nine countries were presented; attendees numbered from 80 to 100. The organizing committee for the symposium was as follows: Prof. PAUL A. LIBBY, Polytechnic Institute of Brooklyn, U.S.A., Chairman; Prof. LuiGI BROGLIO, University of Rome, Italy; Prof. B. FRAEIJS DE VEUBEKE, University of Liege, Belgium; Dr. D. G. KING-HELE, Royal Aircraft Establishment, Farnborough, Rants, United Kingdom; Prof. J. M. J. KooY, Royal Military School, Breda, Netherlands; Prof. JEAN KovALEVSKY, Bureau des Longitudes, Paris, France; Prof. RuDOLF PESEK, Academy of Sciences, Prague, Czechoslovakia. The detailed arrangements for the meeting were made in a most satisfactory manner by Dr. FRANK J. MALINA, Deputy Director of IAA and Mr. A. R. WEILLER, Acting Secretary of IAA. Prof. THEODORE VON KARMAN, Director of IAA, in his remarks closing the symposium indicated his satisfaction at the interest being shown in "the science of the future." The papers which follow will make a permanent contribution to the literature of this science.
