While I was driving south on Highway 29 past the University last
year, a co-worker who was new to NASA called my cell phone and asked,
"What does it mean when the shuttle is late?" The countdown
clock at Cape Canaveral had reversed direction and started counting
upward. The crowd in Florida anxiously awaited the welcoming sonic
boom announcing the arrival of the space shuttle Columbia. The boom
never came. One year later we are memorializing our fallen friends,
family members and heroes.
For
almost 15 years I have been involved with the space program, thanks
to the Engineering School at the University of Virginia. Former
engineering professor Glenn Stoner invited me to assist him with
electrochemistry research while I was still pursuing dreams of a
career as a wide receiver with the Dallas Cowboys. I was able to
take graduate courses in materials science via videotape while catching
footballs by day for Tom Landry's America's Team. Eventually an
injury derailed my gridiron goals, but a welcoming faculty at Virginia
brought me back into the classroom and returned me to the engineering
track.
As an engineer, I worked for nine years at NASA Langley Research
Center before receiving the call to join a different "America's
Team" - the Astronaut Corps. Throughout my career I have utilized
engineering principals to apply health-monitoring smart sensors
to aerospace vehicles, helping to ensure a safe and cost-effective
operation. Currently, I serve at NASA Johnson Space Center in the
Robotics Branch, which is intimately involved with the shuttle "Return
to Flight" efforts. The shuttle robotic arm will be used with
a sensor suite to help ensure that the shuttle's thermal protection
systems are not compromised in future flights.
Engineering is about more than building, designing and synthesizing.
It is about making life more productive and safer for humankind.
Our nation has paused to redefine its space policy in the wake
of the Columbia tragedy. I was in Washington, D.C., when President
Bush announced our new space vision to return humans to the moon,
with future explorations to Mars. As engineers, it is our duty to
make certain that the next generation of explorers is well equipped
with the tools necessary to meet this challenge.
These young minds that we inspire now will follow in the unprecedented
tracks made on the Martian surface by NASA rovers Spirit and Opportunity.
With SPIRIT and OPPORTUNITY, we can do anything!
