Stephanie Wilson was born in Boston, Massachusetts on September 27, 1966. About a year later, her parents, Eugene and Barbara Wilson, decided to move to Pittsfield, Massachusetts. Eugene, a native of Nesmith, South Carolina, used his electronics training from his time in the Navy to get himself a degree from Northeastern University and a long career in electrical engineering for Raytheon, Sprague Electric, and Lockheed Martin, while Barbara worked as a production assistant for Lockheed Martin. After attending Stearns Elementary School, she attended Crosby Junior High School. For a career awareness class in middle school, Wilson was assigned to interview someone in a field that interested her. Since she liked to look up at the sky, she interviewed Williams College astronomer Jay Pasachoff, , clarifying her potential career interest in space. In high school, Eugene encouraged Stephanie to go into engineering, so she decided to become an aerospace engineer. Wilson graduated from Taconic High School, Pittsfield, Massachusetts, in 1984. She attended Harvard University, receiving a bachelor of science degree in engineering science in 1988. Wilson earned a Master of Science degree in aerospace engineering from the University of Texas, in 1992. Wilson has returned to Harvard as a member of the Harvard Board of Overseers. She was the Chief Marshal for the 362nd Harvard Commencement on May 30, 2013.
With the GRAIL data, the astronomers were able to map the gravity field both in and around over 1,200 craters on the lunar far side. This region--the lunar highlands--is our Moon's most heavily cratered, and therefore oldest, terrain. Heavily cratered surfaces are older than smoother surfaces that are bereft of craters. This is because smooth surfaces indicate that more recent resurfacing has occurred, erasing the older scars of impact craters. The precise chemical composition of these very alien lakes and seas remained unknown until 2014, when Cassini's radar instrument detected Ligeia Mare, now known to be Titan's second-largest hydrocarbon-filled lake. Ligeia Mare is brimming with an abundance of sloshing methane, and this enormous liquid reservoir is approximately the same size as two of Earth's Great Lakes combined--Lake Michigan and Lake Huron. Many planetary scientists think that the seabed of Ligeia Mare may be blanketed with a thick layer of sludge that is composed of organic-rich compounds. If you want to measure our solar system, how would you do it? This simplest way is to measure it in light years. For those not familiar with the term, a light-year is the distance that light travels in a vacuum in one year. This is because the distances between stars is so huge that it is otherwise very challenging to imagine them. A light year is exactly 9,460,730,472,580.8 kilometers. Putting this into real world distances, the Milky Way is approximately 100,000 light-years across.
