STS-107 Report #13; Monday, January 27, 2003 -- 5:30 P.M.
CST
Some experiments have run their course aboard the
Space Shuttle Columbia, but there is more in store as STS-107
science continues around the clock in the Spacehab Research Double
Module.
The Structures of Flame Balls experiment, looking at ways of
improving engine combustion efficiency, was shut down after a total
of 39 tests using 15 different fuel mixtures. A total of 55 flame
balls were ignited, including the weakest and leanest flames ever
burned. The longest-lived flame burned in space for 81 minutes,
part of a total burn time for all flames of 6 1 /4 hours.
Oscillating (shrinking and growing) flame balls, which had been
predicted theoretically, were observed for the first time.
The Mechanics of Granular Materials test, looking for ways to
better understand and deal with soil movement associated with
earthquakes, completed its 10th and final run. The Microbial
Physiology Flight Experiment expended its eighth and final set of
samples looking at yeast and bacteria growth in microgravity. The
Canadian-developed Osteoporosis in Orbit also completed its
operations.
The Red team, or day shift – Commander Rick
Husband, Mission Specialists Kalpana Chawla and Laurel Clark and
Israel Space Agency Payload Specialist Ilan Ramon – took time
out from microgravity experimentation about 11:30 a.m. CST to chat
with the other three spacefarers on orbit – Commander Ken
Bowersox, NASA ISS Science Officer Don Pettit and Flight Engineer
Nikolai Budarin. At the time, the space station was some 240 miles
above Southern Russia while the shuttle was over northern
Brazil...
