6/23/93: SHUTTLE OZONE DATA RETRIEVED FROM ATMOS RECORDER
Brian Dunbar
Headquarters, Washington, D.C. June 23, 1993
Jim Doyle
Jet Propulsion Laboratory, Pasadena, Calif.
RELEASE: 93-118
Important ozone data was saved by a new tape recorder during an April
Space Shuttle mission.
Despite transmitting problems, the on-board data recovery system
captured 103 orbital sunrises and sunsets observed by the Atmospheric Trace
Molecule Spectroscopy (ATMOS) instrument. ATMOS, part of the second
Atmospheric Laboratory for Applications and Science (ATLAS 2), measures up to
40 gases that affect global ozone levels. The ATLAS 2 mission's orbital path
allowed ATMOS to measure the gases over high northern latitudes during the
early spring, when the atmosphere is changing from winter to summer circulation
patterns. These circulation patterns affect the weather conditions that can
lead to ozone depletion.
The ATLAS series, which began in 1992, is part of NASA's Mission to
Planet Earth, which uses the unique global perspective available from space to
study how the environment changes. The ATLAS instruments observe the chemical
makeup of the atmosphere and the energy output of the Sun, two of the key
factors in the creation and depletion of ozone.
ATMOS has flown aboard the Shuttle two other times but the April
flight, designated STS-56, was an engineering test flight for the ATMOS
recorder subsystem.
During the flight, the Shuttle's telemetry system, which would have
transmitted ATMOS data to the ground during flight, ran into problems.
ATMOS/Spacelab controllers and the Space Shuttle flight team developed a plan
that allowed the Spacelab's high data rate recorder to record some data on the
orbiter data system and transmit it at a reduced rate. Unfortunately the data
included some errors, project officials said, rendering most of this data
useless.
The ATMOS team was able to rely on its recorder subsystem, a separate,
dedicated data recording system that uses a tape recorder manufactured by
Schlumberger Industries, a French company. The recorder saved the atmospheric
observations, said ATMOS Assistant Project Manager Greg Goodson. In early June,
the data tape was played back for the first time at NASA's Jet Propulsion
Laboratory, Pasadena, Calif.; scientists found the data's quality to be
excellent.
The new recorder subsystem, which has a 44-gigabyte (353 billion bits)
storage capacity, recorded more than half of the scheduled ATMOS observations
-- nearly 6-1/2 hours of data. Results of the data analysis, which is already
underway, are expected to be published within the next year, Goodson said. The
results will present a better understanding of the gases that damage the ozone
layer.

STS-57 Status Report #5
Wednesday, June 23, 1993, 5 a.m. CDT
Endeavour's crew worked with a host of secondary experiments this morning as
their spacecraft drew ever nearer to one of the the main objectives of the
mission -- tomorrow's capture of the European Retrievable Carrier satellite.
Today's activities so far have included more operations with the Superfluid
Helium On-Orbit Transfer experiment in the cargo bay; an evaluation of
soldering in weightlessness by Pilot Brian Duffy; continued work with crystal
growth, materials processing and biological experiments in the Spacehab module;
and the activation of several student-devised experiments in the cargo bay.
Early this morning, experimenters at NASA's Goddard Spaceflight Center in
Greenbelt, Md., successfully completed a third run of the SHOOT experiment, and
Endeavour's Commander Ron Grabe fired the shuttle's steering jets so the
experimenters could guage the effects of the disturbance on their equipment. A
second, similiar engine firing is planned later today as well as more SHOOT
runs. SHOOT studies technology that may one day lead to a method of refilling
satellites in orbit with liquid helium, used for cooling various science
instruments.
Duffy's soldering work is part of an evaluation of maintenance equipment that
may be used on the space station. Duffy began by soldering several electrical
connections together at a special workbench in the Spacehab. Next, he'll
evaluate removing solder from several electrical connections.
Later today, Grabe will fire Endeavour's large orbital maneuvering engines at
around 12:10 p.m. central to continue refining Endeavour's closing on EURECA,
and a second engine firing also may be performed later in the day to prepare
for tomorrow's rendezvous. Endeavour is now about 1,300 nautical miles behind
EURECA, moving closer by about 195 nautical miles with each 93-minute long
orbit.
The crew was awakened at 12:37 a.m. central today by the song "The Smurfs,"
played to them by Mission Control in honor of Mission Specialist Nancy
Sherlock, whose nickname among the astronaut corps is "Smurf."

MISSION CONTROL CENTER
STS-57 Status Report #6
Wednesday, June 23, 1993, 3:30 p.m. CDT
The STS-57 crew completed its third work day in space this afternoon. Mission
Commander Ron Grabe completed a pair of jet firings this afternoon to bring
Endeavour closer to the EURECA satellite for Thursday's early morning
retrieval. The first maneuver at 12:08 p.m. helped Endeavour move closer to
EURECA and the second maneuver at 12:55 p.m. brought the Shuttle into a
co-elliptic orbit with EURECA--so that both spacecraft are precisely the same
distance apart in their separate orbits around Earth. Endeavour is now 291
nautical miles behind EURECA, closing in at 32 nautical miles per 94-minute
orbit.
David Low and Jeff Wisoff with assistance from Brian Duffy checked out the
space suits that Low and Wisoff will wear on Friday during a spacewalk to test
tools and procedures that may be used during the Hubble Space Telescope repair
mission later this year. The suit checks went well and both suits are fully
ready for the spacewalk.
The Spacehab module work was completed for today at 2 p.m. CDT. The soldering
experiment conducted by Brian Duffy at a special workbench in the Spacehab
included soldering several electrical connections onto a printed circuit board
and removing the solder from some electrical connections.
Nancy Sherlock reported getting excellent photography of the Bahama Islands for
the CAN-DO project, a student experiment mounted in canisters in the cargo bay.
Students in the Charleston County School District, South Carolina, assembled
the experiment that features a camera to take more than a thousand photos of
Earth for studies of the environment. A second part of the experiment studies
the effects of space on hundreds of different materials.
The space station experiment, Environmental Control and Life Support System
Flight experiment, has a partial clog in the unibed filter. The experiment
tests components of the water recycling system under development for the space
station. An inflight maintenance procedure performed by David Low did not
unclog the filter. Experiment managers plan to evaluate the situation further
while letting this first half of the experiment continue to run in the hope
that some data may be gathered from partial operation. The second half of the
experiment is scheduled for Saturday.

MAGELLAN STATUS 6/21/93
Magellan Status Report as of 6/21/93
1. With 27 days elapsed in the 80-day Transition Experiment, the Magellan
mission still has a margin of 15 days in the estimated completion of
aerobraking.
2. The spacecraft has made 220 drag passes in the upper atmosphere, and the
apoapsis has been reduced by over 2700 km. The apoapsis will be reduced by
almost 8000 km by the end of the Transition Experiment. All subsystems are
nominal.
3. Corridor Orbit Trim Maneuver #6 was executed early Sunday morning, raising
the periapsis by about 700 m. COTM7 is expected by Wednesday or Thursday of
this week.
4. The move of COTM6 by four days from its original predicted time illustrates
the uncertainty of these aerobraking operations. COTM predictions are based on
our best models of the atmosphere, local gravity fields, and the effects of
small forces. As the spacecraft controllers compare the actual performance
with the predictions, adjustments are made to the plan.
5. The atmospheric model includes the effect of local solar time, that is, the
angle of the sun where Magellan makes its drag pass. Currently, the local
solar time is nearing 1:30 PM and will pass to the night side of Venus before
aerobraking is completed. There is greater uncertainty about the nightside
atmosphere.
6. The local gravity field seems to match closely the R50x50S Magellan gravity
field model rather than an earlier gravity model which had been used for
planning the aerobraking experiment.
7. The "small forces" are primarily the thruster firings used to maintain
attitude control during the drag pass. Although these forces are measured in
millimeters/ sec relative to Magellan's velocity in orbit, they have to be
considered when predicting the spacecraftUs orbit several days in the future.
8. The continuous refinement in our predictions is helping the spacecraft team
maintain a "safe" corridor for Magellan's aerobraking experiment.
