uh
and good morning columbia as you're
going well past the wild blue yonder
good morning bill that song sounded
vaguely familiar to me
great to hear your life
well we're ready for another exciting
day uh here in the space business
for right now though we're going to
tembu up a fuel cell purge for you
this is mission control houston this
morning's wake up call
the air force song by the united states
air force academy cadet chorus
that for pilot steve lindsay who is a
major in the air force and
commander kevin kriegel formerly of the
air force
this is usmp4 science operations control
huntsville science activities aboard the
space shuttle columbia continue to go
well this afternoon a new growth cycle
is underway with the isothermal
dendritic growth experiment
the study is designed to improve metals
used in automobiles and jet engines
in the experiment materials are melted
and re-solidified to observe the growth
of dendrites you're looking now at live
video downlinked from the shuttle
columbia of the idge experiment as the
dendrite grows in space in the
microgravity environment idg's lead
scientist professor matthew koss of
rensselaer polytechnic institute in troy
new york says the science team is
repeatedly performing growth cycles at
the same super cooling this allows
researchers to obtain the best science
data set possible for later analysis
and the growth cycles continuing with
the idge experiment on board the space
shuttle columbia
also today uh very uh
good reports from the science teams both
with mephisto and another furnace on
board columbia
the advanced automated directional
solidification furnace
these views showing some of the payloads
in the cargo bay
these payloads many of them have been
operating throughout the mission
mounted in canisters in columbia's
payload bay
they include
various technology experiments so
studying uh new technologies that can be
used on future spacecraft
among those are a study of a heat pipe
technology that can be used for cooling
a passive cooling system that would
include no moving parts
being studied for possible use on future
satellites
that experiment is called the loop heat
pipe experiment it's sponsored by the
center for space power at texas a m
university in corpus christi texas
also another experiment in the cargo bay
along with the heat pipe experiment is
uh called the
sodium sulfur battery experiment looking
at
how sodium sulfur batteries can operate
in weightlessness a possible source of
battery power for future spacecraft
other experiments in the cargo bay that
have been operating throughout
columbia's mission include the turbulent
gas jet diffusion flames experiment
that experiment
seeks to understand the characteristics
of
turbulent gas jet diffusion flames and
wasteless weightlessness
training session underway as we see
jerry ross here is to evaluate the
handling characteristics of the
satellite
he and his colleague jim newman have
been passing the uh
the mock-up of the spartan
back and forth to
understand and get a good feel for its
handling characteristics
the spartan actually
weighs in at about 1200 pounds of course
in space with microgravity uh it really
has no weight but its mass is still
there so it is
the prudent thing to do to understand
the the handling characteristics of the
uh
spartan satellite
so they'll continue this training
session for another a couple of hours in
the uh water tank
which is uh
near the johnson space center here in
houston
and this wider view
gives a better idea of the size of the
satellite in relation to the two
astronauts
and again in this view jerry ross is on
the
left and jim newman is on the right
they are distinguishable by their air
hoses which obviously are not used in
space but underwater they are and
jerry ross's is red and jim newman's is
white
oh
is
foreign
you
