Students' microgravity experiment on Space Shuttle
ANN ARBOR -- On Thursday (Dec. 3), when Space Shuttle Endeavour blasts off
from Kennedy Space Center in Cape Canaveral, Fla., its payload will include
an experiment designed and built by University of Michigan students. The
launch is scheduled for 4 a.m.
Endeavour's main mission is to begin construction of an International Space
Station that is expected to be completed in 2004. Carrying a U.S.-made
connecting module called Unity, the shuttle will rendezvous with Zarya, a
Russian-built command and control module that was placed in orbit on Nov.
24. During space walks, astronauts will attach the modules to one another.
The astronauts will also be responsible for starting and stopping the U-M
experiment, known as VORTEX (short for Vortex Ring Transit Experiment).
VORTEX is the result of thousands of hours of work over a four-year period
by more than 60 U-M College of Engineering students from the Department of
Aerospace Engineering and the College's Department of Atmospheric, Oceanic
and Space Sciences, as well as the College's Space Physics Research
Laboratory.
The experiment is designed to answer some basic questions about fluid
atomization, the process by which a liquid is converted into tiny droplets.
The microgravity environment of the orbiting Space Shuttle will allow a
closer look at the physics of the process because the students will be able
to generate larger atomized droplets than are possible on Earth.
The main components of the experiment -- all contained in a special canister
-- are a fluid test cell system, a laser-based illumination system, a digital
imaging system, and a computer-based data acquisition and control system.
Data collected by VORTEX could one day be applied to problems ranging from
the atomization of fuel for internal combustion engines to the manufacturing
of microdroplets for drug delivery.
Students have managed all aspects of the project, from fund-raising to
technical issues. Sven Bilen, who recently earned his doctoral degree in
engineering, was the student leader. John Korsakas, who graduated with a
degree in electrical engineering, oversaw computer and control systems.
Aerospace engineering Prof. Luis P. Berna served as faculty adviser for the
effort, as well as liaison between the student team and NASA.
VORTEX has already paid substantial educational dividends. "In addition to
the important physics questions to be answered, we have learned how to work
with industry, academia, and government," said Bilen. "We have gained
valuable, hands-on experience with a real-world engineering project."
Last August, the students delivered VORTEX to NASA personnel at Kennedy Space
Center, and participated in the process of integrating their experiment with
the space shuttle mission. A year earlier, three of the students traveled to
Johnson Space Center in Texas to test VORTEX in near-weightless conditions
aboard the same KC-135A research aircraft seen in the movie Apollo 13 and
used to train NASA astronauts.
Sponsors of the U-M VORTEX experiment include: General Motors, Hewlett-
Packard, IOTech, Michigan Space Grant Consortium, Microsoft, MINCO Corp.,
Nematron Co., Sears, Tektronix, TRW, Utica Engineering, Utica Printing, U-M
Engineering Council, and U-M Student Assembly.
VORTEX is part of NASA's Get Away Special (GAS) Program, which allows
individuals and organizations of all countries to fly small scientific or
engineering payloads on a Space Shuttle at relatively low cost ($10,000 for
U.S. educational organizations, $27,000 for other U.S. and foreign payloads.)
The experiments must weigh less than 200 pounds and fit inside a standard
5.0-cubic-foot GAS canister manufactured by NASA.
