Former astronaut and retired Marine major general Charles Bolden, Jr., 62, is the front-runner to become the next administrator of the National Aeronautics and Space Administration otherwise known as NASA. He is meeting with President Obama today. If his nomination is confirmed, Bolden will be the first African-American to head NASA, according to the New York Times. While Gen. Bolden is familiar with NASA, his past as an astronaut (he flew in four space shuttle missions in the 1980s and 1990s) and sitting on the board of directors for Gencorp, Inc, a company that contracts to build parts for space shuttles, may work against him since there are some questions of ethics and conflict of interests.—WLW
