Professors feel pain of lost lives, science in shuttle disaster
The disappointment of losing scientific research aboard the Space Shuttle
Columbia pales in comparison to the immense grief of losing the seven
astronauts. It's impossible, however, for scientists involved in NASA
projects, including many at ASU, not to wonder how the tragedy will impact
their ongoing research.
Overall, ASU researchers say the disaster will create a greater resolve
to create safer, better ways to explore the unknown.
"I think there is a great drive to explore space that will not be deterred
by this," says Laurie Leshin, an ASU cosmochemist who has a proposal before
NASA for an unmanned mission to Mars. "If anything, this causes us to
dig in our heels even more and try to get out there more safely and more
often."
University researchers have a long tradition of working with NASA. In
fact, the disaster had a direct link to ASU, as the shuttle was carrying
the research of a faculty member and an ASU alumnus.
Professor Petra Fromme, from the chemistry & biochemistry department,
lost all of her research data aboard the shuttle when it broke apart on
reentry. She was growing a series of protein crystals aboard the shuttle
and, upon returning to earth, the crystals would have been exposed to
an ultra-high level x-ray. This would have provided a clear, high resolution
picture of the protein's structure down to the atomic level. Defining
the structure would have given researchers a better understanding of the
process of photosynthesis - nature's process for converting light to energy.
Fromme was in Florida at Kennedy Space Center where the shuttle was scheduled
to land. Within four hours of its landing, Fromme would have removed the
crystals the shuttle and prepared them for transport. The data from the
experiment, including a video of the crystals' growth, was all self-contained
with the experiment on the shuttle.
As the tragedy unfolded throughout the day Feb. 1, Fromme and the other
researchers who had projects on the shuttle were sequestered at the space
center. She remained in Florida through Feb. 3 to disassemble the control
study she was doing with the project. She is scheduled to attend two academic
conferences and will not return to Tempe until mid-February.
Cindy Hutchens, a 1986 graduate from ASU in mechanical engineering, was
in charge of the Vapor Compression Distillation Flight Experiment aboard
the Columbia. The project was a full-scale demonstration of technology
to turn crew members' urine and wastewater aboard the International Space
Station into clean water for drinking, cooking and hygiene.
With the entire shuttle fleet now grounded as NASA investigates the cause
of the disaster, other shuttle research projects, as well as several related
to ASU, are on hold.
Three Corner Sat, a fully functional three satellite constellation built
by ASU students in collaboration with New Mexico State University and
the University of Colorado at Boulder, was planned for launch from the
shuttle later this year or early in 2004.
"Obviously the loss of human life is the most important concern," says
Helen Reed, engineering professor and faculty adviser for the ASU student
satellite program. "The key issue is to determine the cause and to fix
it for future missions. We will face a delay but that is a minor concern.
I know the students in our program are still dedicated to launching our
satellite, and our program will continue to move forward."
Reed said she met Feb. 2 with several of her U.S. Air Force contacts,
who are major sponsors for the Three Corner Sat, and they assured her
the satellite would still be launched.
Reed said in the last week she has heard from many of her current and
former students about the disaster. In the nine years since the student
satellite program began, more than 600 undergraduate and graduate students
have been involved. Most of the former students are now working in some
capacity in the aerospace industry, including former students at both
Kennedy Space Center in Florida and Johnson Space Center in Texas.
The delay in shuttle launches could also have an effect on a major tool
used by many ASU researchers - the Hubble Space Telescope. A maintenance
mission for the telescope is scheduled for a shuttle mission in 2005.
Rogier Windhorst, a professor in the physics and astronomy department,
said that without the proper maintenance, the telescope could fail by
2008.
A failure of the telescope would have a major impact on space research
as a whole and ASU in particular. ASU is considered a major center for
the use of Hubble, used by Windhorst, ASU Astronomy Professor Jeff Hester
and countless graduate and postdoctoral students.
