Q&A with Marc Rayman, chief engineer on NASA’s Dawn mission (members only)

A balky interplanetary seismic instrument that ran into technical problems in 2015, forcing a two-year delay in the launch of NASA’s InSight lander to Mars, cleared a major test last week after engineers redesigned part of the sensor package, boosting confidence that the mission will be ready to blast off in May 2018.

On the eve of the Cassini spacecraft’s deepest pass through the polar plumes of Enceladus, Spaceflight Now’s Stephen Clark spoke with Jonathan Lunine, a member of the mission’s science team from Cornell University, about what he hopes to learn from the encounter.

Processing images from the camera aboard NASA’s Juno spacecraft orbiting Jupiter has turned into a cottage industry of sorts, as rank amateurs, accomplished artists and experienced researchers turn relatively drab “raw” images into shots ranging from whimsical to spectacular and everything in between.
