ESA's Venus Express Mission has monitored Venus since April 2006, and scientists worldwide have used mathematical models to investigate its atmosphere and model its circulation. This book summarizes recent work to explore and understand the climate of the planet through a research program under the auspices of the International Space Science Institute (ISSI) in Bern, Switzerland. Some of the unique elements that are discussed are the anomalies with Venus' surface temperature (the huge greenhouse effect causes the surface to rise to 460 DegreesC, without which would plummet as low as -40 DegreesC), its unusual lack of solar radiation (despite being closer to the Sun, Venus receives less solar radiation than Earth due to its dense cloud cover reflecting 76% back) and the juxtaposition of its atmosphere and planetary rotation (wind speeds can climb up to 200 m/s, much faster than Venus' sidereal day of 243 Earth-days).

On July 14, 2015, something amazing happened. More than 3 billion miles from Earth, a small NASA spacecraft called New Horizons screamed past Pluto at more than 32,000 miles per hour, focusing its instruments on the long mysterious icy worlds of the Pluto system, and then continued on its journey out into the beyond. Nothing like this has occurred in a generation - a raw exploration of new worlds unparalleled since NASA's Voyager missions - and nothing like it is planned to happen again. The photos that New Horizons sent back to Earth graced the front pages of newspapers on all 7 continents, and NASA's website for the mission received more than 2 billion hits in the days surrounding the flyby. At a time when so many think our most historic achievements are in the past, the most distant planetary exploration ever attempted not only succeeded but made history and captured the world's imagination. How did this happen? Chasing New Horizons is the story of the men and women behind the mission: of their decades-long commitment; of the political fights within and outside of NASA; of the sheer human ingenuity it took to design, build, and fly the mission. Told from the insider's perspective of Dr. Alan Stern, Chasing New Horizons is a riveting story of scientific discovery, and of how far humanity can go when we work together toward an incredible goal.

Until very recently, all we really knew about Venus, our nearest planetary neighbour, was that it was roughly the same size and mass as the earth and was surrounded by a thick atmosphere. Then, in 1989, American scientists launched Magellan,the spacecraft that would revolutionize our vision of this mysterious planet. Venus Revealed is the first book to explain the breathtaking results of this mission, which unveiled a Venusian world of active volcanoes, shining mountains, and river valleys carved by torrents of flowing lava. At one time, Venus may have even had a wet, temperate climate, much like Earth's. What happened to turn it into a hostile, burning acid world? The answer could very well help us solve some of our most pressing environmental problems,from global warming to acid rain. In Venus Revealed, David Grinspoon eloquently argues that studying our exotic twin will inevitable teach us more about ourselves.
