    **EU5 Chap 2(263-300) 2/20/03 1:16 PM Page 263 Chapter Two NASA and Planetary Exploration by Amy Paige Snyder Prelude to NASA’s Planetary Exploration Program Four and a half billion years ago, a rotating cloud of gaseous and dusty material on the fringes of the Milky Way galaxy flattened into a disk, forming a star from the inner- most matter. Collisions among dust particles orbiting the newly-formed star, which humans call the Sun, formed kilometer-sized bodies called planetesimals which in turn aggregated to form the present-day planets.1 On the third planet from the Sun, several billions of years of evolution gave rise to a species of living beings equipped with the intel- lectual capacity to speculate about the nature of the heavens above them. Long before the era of interplanetary travel using robotic spacecraft, Greeks observing the night skies with their eyes alone noticed that five objects above failed to move with the other pinpoints of light, and thus named them planets, for “wan- derers.”2 For the next six thousand years, humans living in regions of the Mediterranean and Europe strove to make sense of the physical characteristics of the enigmatic planets.3 Building on the work of the Babylonians, Chaldeans, and Hellenistic Greeks who had developed mathematical methods to predict planetary motion, Claudius Ptolemy of Alexandria put forth a theory in the second century A.D. that the planets moved in small circles, or epicycles, around a larger circle centered on Earth.4 Only partially explaining the planets’ motions, this theory dominated until Nicolaus Copernicus of present-day Poland became dissatisfied with the inadequacies of epicycle theory in the mid-sixteenth century; a more logical explanation of the observed motions, he found, was to consider the Sun the pivot of planetary orbits.5 1.

The entire program is privately funded by members and supporters of The Planetary Society, the world’s largest non- profit space advocacy organization. Spacecraft design started in 2009; by the end of 2011 both spacecraft had largely been built but not fully tested, and neither had a firm launch commitment. Following an 18-month program pause during 2012-2013, the effort was resumed after launch opportunities had been secured for each spacecraft. The first LightSail spacecraft—dedicated primarily to demonstrating the solar sail deployment process—was launched into Earth orbit on 2015 May 20 as a secondary payload aboard an Atlas 5 rocket, and on June 9 mission success was declared. The mission plan for the second LightSail includes demonstration of solar sailing in Earth orbit, among other objectives. It is on track for a launch in 2016 aboard a Falcon Heavy rocket as a key element of the Prox-1 mission.
