Dr Ellen Stofan was, until December 2016, the Chief Scientist at NASA, a post that she held for approximately three and a half years. During a personal visit to Scotland, Ellen took time out to visit SSERC in its Dunfermline Headquarters to find out more about the work of the organisation and to meet some Scottish STEM Ambassadors.  During a round table discussion with STEM Ambassadors, she talked about her career to date and answered questions ranging from equality of opportunity  within the space industry to the potential for a  manned mission to Mars.   Ellen was accompanied by Susan Wilson, Principal Officer at the US Consulate General in Edinburgh and  met with our CEO Alastair MacGregor and Chairman Alan Nimmo.
