Matt Heverly has one of the coolest jobs in the Solar System: he drives rovers. On Mars. He drove NASA's Opportunity rover for four years and now he's getting ready for the biggest mission in the history of NASA's planetary exploration—driving the $2.6-billion car-sized Curiosity rover after it lands this Sunday (I will be covering this amazing event live, crossing my fingers, from the Jet Propulsion Laboratory in Pasadena, California).


Matt is here now to take your questions, starting at 3PM EST/12PM PST.

I love robots. If they are exploring Mars or vacuuming your floor, the idea of a machine intelligently doing a task for you has always been interesting. I always loved to design and build things, and when I discovered that I could make that thing that I built do something cool, I was hooked.


I have worked on snake robots to repair gas pipelines, robots to help with surgery, and legged robots that might help explore the Moon. I was fortunate enough to drive the Opportunity rover on the surface of Mars for four years and am now preparing to drive Curiosity once she lands safely on August 5th. Curiosity will allow us to add another chapter to our understanding of the red planet.

She is the most capable rover ever sent to Mars and will allow us to explore Gale Crater and the 3.1-mile (5-kilometer) tall Mount Sharp as we search for the building blocks of life.

Something you want to ask Matt? He's here—live in the discussion section taking your questions. Fire away!


What Was It is a series of short interviews co-hosted on Gizmodo and io9 that asks the luminaries of science and technology what inspired them.
