Two dozen scientists at the meeting gathered for lunch in the National Portrait Gallery atrium to discuss NASA’s scientific research with volunteers. They discussed projects on asteroids, landslide risk prediction, solar eclipse science, water quality, Martian clouds, and more. Science done with volunteers is often called citizen science or participatory science – it does not require citizenship in a particular country. “Between the immense data sets collected by NASA missions and the eternal need to fling open the doors of science so that everyone can experience the joy and rewards of doing research together, citizen science is more than never necessary!” said Sarah Kirn, a citizen science strategist at the Gulf of Maine Research Institute in Portland.
