Curiosity’s RAD (start time 7:14). To design a successful manned mission to Mars, we’ll have to know a lot about the radiation environment between the Earth and Mars and on the planet’s surface. The Radiation Assessment Detector (RAD) instrument on Curiosity is designed to make those measurements. We talk with Southwest Research Institute’s Dr. Donald Hassler, the RAD instrument Principle Investigator, about RAD’s purpose, how the instrument works, and the joys and scary moments that come with working on Mars.
Planetary science budget (start time: 15:49). Despite the successes of the Mars missions and voyages to our other planetary neighbors, the White House decided that NASA’s planetary science budget should be drawn down. The hit would be substantial, a twenty percent reduction from 2012. 300 million dollars would be removed from a baseline one and a half billion dollars. We ask Dr. Alan Stern, who has served as the chief of the Science Mission Directorate at NASA, about why the planetary science budget should be restored.
