I am one of two people who coordinates the operations of the Mars Pathfinder Rover.
Right now, the Rover Team is spending most of its time training, but when the Pathfinder
spacecraft lands on Mars on July 4, my job will start for real!
The first thing the Rover Team must do is quickly figure out that Sojourner survived
the landing (Sojourner is the official name of the Rover), and that all her systems are
still operating properly. Assuming they are, Sojourner must then make the dangerous
journey off the Lander petal and onto the surface of Mars. This is a difficult and
complex operation that requires good timing between the Lander and Rover, and a keen eye
for understanding the Martian terrain using the pictures the Lander is sending back to
Earth. Until we get off the Lander petal, the Rover blocks the Lander solar array,
forcing the Lander to use limited battery resources.
Once Sojourner has made it off the Lander, we will send her sets of instructions about
where to go, what experiments to do, and which rocks to investigate each day. This may
last for many weeks.
To accomplish all of this, there are teams of Rover engineers doing different things
(one group analyzes the data sent back, some engineers analyze the pictures, others
prepare the instructions to be sent back up to the Rover), and I help coordinate
activities among them. I also help coordinate the activities of the Rover Team with all
the engineers on the spacecraft Lander Team.
My Career Journey
In high school, I got good pretty good grades in math and I enjoyed solving puzzles
and problems. That made me think I might like being an engineer. But I didn't start out
as a spacecraft engineer, I actually began in the Navy. I graduated from the US Naval
Academy in Annapolis, MD and became an officer in the Submarine Force. I spent about five
years driving a Los Angeles Class attach sub around various oceans.
After awhile though, I decided to go back to graduate school to do more technical
engineering. NASA's space program had always interested me. To me, NASA lets you take a
big poke at the unknown, and if you can help solve just a little bit of it, then you
played at least a bit part in everything that happens in the future. So after getting a
masters degree at Caltech, I applied for and was lucky to get a job at the Jet Propulsion
Laboratory, or JPL.
