NASA's chief scientist is leaving the agency after more than three years on the job. Ellen Stofan left NASA this month "for new adventures," according to an interview NASA posted on a social media site earlier this month. Stofan had been chief scientist since August 2013, serving as the principal adviser to the NASA administrator on science issues. Separately, NASA has named a new deputy associate administrator for its science directorate. Dennis Andrucyk, the current deputy associate administrator for space technology, will fill that post in mid-January.
