When the Spirit rover that began beaming color images from the Mars
surface Tuesday starts exploring the dusty, red landscape, a Cincinnati
native, Steve Lever, will help steer it.
Lever,
a computer science specialist for the Jet Propulsion Laboratory in
Pasadena, Calif., is a member of the team that sends computer commands
to the six-wheeled rover across 105 million miles of space.
It will be the most exciting moment of his professional life.
"This
job does beat digging ditches,'' said the 42-year-old Cincinnati
native, who lived in Hyde Park and Groesbeck before moving to Kettering
while he was a fifth-grader at Ann Weigel Elementary School. "And I've
dug ditches in my time.''
Lever is among several Ohioans deeply involved in the current Mars mission.
Ron
Li, a professor of geodetic science at Ohio State University, is
leading a team of Ohio State engineering students working with Jet
Propulsion Laboratory to gather information about the precise location
of the Spirit rover. Researchers at NASA's Glenn Research Center in
Cleveland and its satellite in Sandusky, Plum Brook Station, worked on
the rover's air bag landing system.
Lever's
job title at NASA's JPL is sequence integration engineer. When
geologists and other scientists tell him and fellow engineers what they
want Spirit to do - dig a hole, pick up a rock, turn left, turn right -
he and his co-workers develop computer command sequences that they pass
along to the rover's computer.
"The
scientists put their requests together at the end of each Martian solar
day,'' said Lever, who lives in Pasadena with his wife and three
daughters. "And then we go to work creating the commands to make it
happen.''
Once
Lever and his teammates move the rover out of its current crouched
position later this week, Spirit will be guided toward a dusty crater
scientists call Sleepy Hollow, about 40 feet away.
"This
mission has been so successful so far, it almost takes your breath
away,'' said Lever, who has worked at Jet Propulsion since 1984.
"People know here what it is to have a mission fail. That makes this
especially sweet.''
Lever
has worked on several Mars missions, successful and unsuccessful, since
leaving a job as a computer specialist for a California savings and
loan to join Jet Propulsion.
He
left Ohio after graduating from Kettering Fairmont East High School in
1979 to study computer science at California State University; and he
later earned a masters' degree in computer science from Azusa Pacific
University.
Once
a year, Lever returns to Cincinnati to visit his aunt, Patricia Reams,
in White Oak and to go to a Bengals game. Lever has Bengals season
tickets, most of which he sells on eBay.
