| Oklahoma City professor sends project on space
shuttle Sept. 14, 2006
By United Methodist News Service*
A professor at a United Methodist-related college is participating in
activities aboard Space Shuttle Atlantis, which docked with the
International Space Station on Sept. 11.
Kent Buchanan, a biology professor at Oklahoma City University, sent a
“life science experiment” to space to investigate the effect of space flight
on microbes—microscopic organisms, particularly bacteria that can cause
disease. Buchanan’s research is on microbial gene expression and virulence.
He is one of four scientists studying organisms on the shuttle. The group received a $1 million grant from NASA for the work about five years ago. Several organisms are being tested; Buchanan’s focus through the Candida Project is on a microbe called Candida albicans.
Buchanan and his team prepared for the space shuttle launch for two and a half years. Prior to Atlantis’ Sept. 9 launch, the team had waited through cancellations and other delays caused by bad weather, equipment failure, Hurricane Katrina and the Space Shuttle Columbia disaster.
“This is only the third flight since Columbia, and a lot of life science
projects were cut,” Buchanan explained. The Space Shuttle Columbia
disintegrated upon re-entry into the Earth’s atmosphere in 2003. “Since this
is going up now, it signals that it’s a high priority for NASA.”
While the organisms are in space, an astronaut will rotate the container
that holds them to initiate the experiment and then repeat the process
periodically to keep it going. “Every time they do something in space, we’ll
do the identical on the ground, so that the only difference is they’re in
space,” Buchanan said.
The results will help determine the effect of space on organisms that
have the potential to cause diseases in astronauts during long-term flight.
Chery Nickerson at Arizona State University is the principal investigator
for the project. Buchanan is a co-investigator, along with Tim Hammond and
Michael Schurr of Tulane University Health Sciences Center.
Buchanan moved to Oklahoma City last year from the New Orleans area after
Hurricane Katrina left the Tulane University Medical Building where he
worked inoperable. He said he was thankful to be able to continue teaching
and working on the experiment, and he plans to travel to the Kennedy Space
Center in Cape Canaveral, Fla., for Atlantis’ landing on Sept. 19.
“We’ll get (the organisms) off the shuttle as fast as we can for the
virulence studies,” he explained.
“The astronauts are very excited about it,” he said. “This has become one
of the highlights in my scientific career. It has turned out to be a big
honor for me.”
The six-member crew of Atlantis launched Sept. 9 on an 11-day
construction mission to the International Space Station.
