William J. Borucki is a space scientist working at the NASA Ames Research Center.Upon joining NASA in 1962, Borucki designed the heat shields for Apollo program spacecraft.He later turned his attention to the optical efficiency of lightning strikes in the atmospheres of planets, investigating the propensity that these lightning strikes could create molecules that would later become the precursors for life.Subsequently, Borucki's attention turned to extrasolar planets and their detection, particularly through the transit method.In light of this work, Borucki was named the principal investigator for NASA's Kepler mission, launched on March 6, 2009 and dedicated to a transit-based search for habitable planets.In 2013, Borucki was awarded the United States National Academy of Sciences's Henry Draper Medal for his work with Kepler. In 2015 he received the Shaw Prize in Astronomy.
