Deep Impact, or at least part of the flight system, is designed to crash into comet 9P/Tempel 1. This bold mission design enables cometary researchers to peer into the cometary nucleus, analyzing the excavated material with its imagers and spectrometers. The book describes the mission, its objectives, expected results, payload, and data products in articles written by those most closely involved. This mission has the potential of revolutionizing our understanding of the cometary nucleus.

Non sono necessariamente richiesti strumenti mastodontici per produrre risultati scientificamente validi nel campo dell'astronomia. Anche l'astrofilo dotato di un piccolo telescopio, con un diametro di soli 8-9 cm, puo contribuire alla scienza del cielo realizzando utili osservazioni del Sole, della Luna, dei pianeti, delle comete, degli asteroidi, delle stelle doppie o variabili, delle nebulose e degli ammassi stellari.

Il manuale di M.K. Gainer spiega quale sia la dotazione minima (un piccolo telescopio, un computer, una semplice fotocamera digitale), come utilizzarla, e quali siano...

Many amateur astronomers are short of time. A full-time career usually takes up most waking hours, and there very often simply isn t time for leisurely observing sessions, at least a few hours sleep being something of an imperative during the week. Fortunately, modern technological advances such as computer-controlled telescopes equipped with GPS, north-seeking and level detection, have made setting up a telescope much quicker. Today s imaging systems enable time-pressed astronomers to take excellent astrophotographs of many objects without the hours-long exposures that used to be a...

This well-researched and clearly-written book tells the story of the complications involved in NASA's selection of astronauts. The Real Stuff is the history of NASA's astronaut recruitment and selection process from 1959-1984. The authors consider the various criteria applied in selecting astronauts from among military test pilots, scientists, and mission specialists, and demonstrate the scientific and social concerns which led to the policy changes that brought scientific specalists, women, and minorities into the space program. Included are such topics as: the Eisenhower space...

Instead of taking somebody's word for it about the basic size and distance statistics for the solar system, this book shows amateur astronomers how to measure these things for themselves. This is an enriching experience for any amateur astronomer - to understand and personally measure some fundamental astronomical quantities and distances.

A basic knowledge of geometry is required, but it is amazing how simple the geometry can be. Readers are led through the geometry as gently as possible - and in a light-hearted way - presuming that most non-academics will have half-forgotten most...
