Larry Matthies BSc'79<br />

HIGH LIGHT<br />

If there ever was a U <strong>of</strong> R<br />

alumnus with an out-<strong>of</strong>this-world<br />

job, it's Larry<br />

Matthies BSc'79. Matthies is a<br />

computer scientist at the Jet<br />

Propulsion Laboratory (JPL) in<br />

Pasadena, Calif., the agency<br />

that manages the Mars<br />

Exploration Rover project for<br />

the National Aeronautics and<br />

Space Administration (NASA).<br />

Matthies leads a team <strong>of</strong><br />

scientists that developed the<br />

computerized vision system<br />

used by Spirit and Opportunity, the two robotic<br />

vehicles that rolled <strong>of</strong>f their landers in January to<br />

search for signs <strong>of</strong> life on the red planet.<br />

The image processing s<strong>of</strong>tware developed by<br />

Matthies' team was crucial to the Mars mission. First,<br />

the system was used to estimate the landing crafts'<br />

velocity and slow them, as necessary, for a safe<br />

landing. Secondly, the system was used to create a<br />

three-dimensional representation <strong>of</strong> the surface that<br />

allowed the rovers to safely navigate across the rocky<br />

Martian terrain.<br />

"For my group, our greatest fear was the failure <strong>of</strong><br />

the descent system because it's mission-critical,"<br />

explains Matthies. "The reconstruction they did after the<br />

landing <strong>of</strong> Spirit suggested that if that system hadn't<br />

worked we might have landed too hard on the surface."<br />

Although he earned his BSc in computer science with<br />

distinction, Matthies was no one-trick pony. When he<br />

wasn't busy learning he was involved in many<br />

extracurricular activities including being involved in the<br />

computer science social club and serving as student<br />

representative to faculty senate, member-at-large <strong>of</strong> the<br />

Students' Union and chair <strong>of</strong> the U <strong>of</strong> R Debating Society.<br />

"Those things broadened my experience and made<br />

me a more well-rounded person," he says. "They gave<br />

me skills for things like giving presentations and<br />

running meetings. Those skills have been quite<br />

valuable along the way."<br />

Matthies says that robots with similar vision<br />

systems have military applications and could be used<br />

in hostage situations or in the aftermath <strong>of</strong><br />

earthquakes when searching collapsed buildings is too<br />

difficult or dangerous. As well, such robotic vehicles<br />

are used in automated mining operations and for<br />

automated cargo movement at shipping ports. Still,<br />

it's using the technology for deep space exploration<br />

that most intrigues Matthies.<br />

"To me, the two biggest questions are: Is there life<br />

elsewhere and why is there a universe in the first<br />

place?" Matthies says. "I'm very fortunate to help the<br />

scientists who are working to answer those questions."<br />

In early March, data collected by the rover<br />

Opportunity led scientists to conclude that the<br />

Martian surface once held an abundance <strong>of</strong> water and<br />

therefore may have been capable <strong>of</strong> supporting life as<br />

we know it.<br />
