A search for a scientist who disappeared while exploring the Martian desert. He is Alwyn Stafford and as the search progresses it becomes clear he has discovered something which other people want kept hidden. A new alien civilization? A first novel by a Mars astronomer.

Examines the evidence in photographs of the surface of Mars for the existence of a lost city on the planet.

This study, commissioned by the National Aeronautics and Space Administration (NASA), examines the role of robotic exploration missions in assessing the risks to the first human missions to Mars. Only those hazards arising from exposure to environmental, chemical, and biological agents on the planet are assessed. To ensure that it was including all previously identified hazards in its study, the Committee on Precursor Measurements Necessary to Support Human Operations on the Surface of Mars referred to the most recent report from NASA's Mars Exploration Program/ Payload Analysis Group (MEPAG) (Greeley, 2001). The committee concluded that the requirements identified in the present NRC report are indeed the only ones essential for NASA to pursue in order to mitigate potential hazards to the first human missions to Mars.

Since he was a boy, Julius Stetson dreamt of what life would be like on another planet. After a tragic work accident, he gets an unprecedented chance to make his dream a reality. However, fate plays a cruel trick. As his Martian dream descends into nightmare, the man from Pontiac must make an impossible choice. No matter what he does, his decision will change both worlds.

Gritty and scientifically accurate science fiction adventure from New York Times best-selling author Ben Bova and NASA space scientist Les Johnson. The first human mission to Mars meets with near-disaster when a meteoroid strikes the spacecraft, almost destroying it. The ship is too far from Earth to simply turn around and return home. The eight-person crew must ride their crippled ship to Mars while they desperately struggle to survive. On Earth, powerful political forces that oppose human spaceflight try to use the accident as proof that sending humans into space is too dangerous to continue. The whole human space flight program hangs in the balance. And if the astronauts can’t nurse their ship to Mars and back, the voyagers will become either the first Martian colonists—or the first humans to perish on another planet.

The Jamakkol prasanam is a distinguished technique of horary method of prediction. It is widely practiced in Tamilnadu and for the first time, this procedure is made available in English through this Book. By crossing this language barrier, the Jamakkol prasanam system offers a novel and simple method of astrological divination. This will benefit the astrological community residing in other parts of India and the world. This method is not alien to the conventional and traditional system of astrology. It encompasses all the rules, procedures and the practices of the Parasara system only. It differs in the approach with specific and special rules. The Jamakkol prasanam uses the three vital factors namely the Udhaya, the Aaruda and the Kavippu. These three fundamentals join the Jama planets and their interaction paves the way for the astrological predictions. This book teaches from the basis of the calculations involved in finding the Udhaya, the Aaruda and the Kavippu and also the procedure to fix the Jama planets. The Kaarakathuvas of the planets, the bhavas and the signs are important to arrive at exact results. So they are dealt exhaustively and exclusively. This will be helpful not only to the practitioners of the Jamakkol prasanam, but also to the astrologers in general. Case studies have been included to facilitate the easy comprehension of the Jamakkol system.
