The Space Exposed Experiment Developed for Students (SEEDS) offers a
wide variety of opportunities for student experiments. Investigators will
provide a total of 12.5 million tomato seeds, packaged in kits, to students
from the upper elementary through the university level. Students will have
the unprecedented opportunity to study the effects of long-term space
exposure on tomato seeds. The program encourages active student
involvement and a multidisciplinary approach, allowing students to design
their own experiments and to be involved in decision making, data
gathering and reporting of final results.
The low cost of an LDEF experiment encouraged high-risk/high-return
investigations and made experiments particularly attractive to students
and research groups with no experience in space experimentation.
Investigators could take advantage of NASA and private industry expertise
to develop relatively inexpensive investigations.
The LDEF structure was designed and built at the Langley Research
Center in Hampton, Va. Experiment trays were provided to investigators,
who built their own experiments, installed them in trays and tested them.
To help reduce costs, each investigator established the amount of reliability,
quality control and testing required to insure proper operation of his
experiment.
The LDEF project is managed by Langley for NASA's Office of
Aeronautics and Space Technology in Washington, D.C. E. Burton
Lightner is Manager of the LDEF Project Office. William H. Kinard is
LDEF Chief Scientist and Head of the Data Analysis Team.
AMERICAN FLIGHT ECHOCARDIOGRAPH
The American Flight Echocardiograph is an off-the-shelf medical
ultrasonic imaging system modified for Space Shuttle compatibility. The
AFE noninvasively generates a two-dimensional, cross-sectional image of
the heart or other soft tissues and displays it on a cathode-ray tube (CRT) at
30 frames per second.
AFE has flown before on STS-51D and is designed to provide inflight
measurements of the size and functioning of the heart and record heart
volume and cardiovascular responses to space flight. Results from the AFE
will be used in the development of optimal countermeasures to crew
cardiovascular changes.
Operated by STS-32 Mission Specialist Marsha Ivins, the AFE hardware
will be stored in an orbiter middeck locker. All five crew members will
participate in the experiment as subjects as time allows. Crew members
also will use the AFE to support Detailed Secondary Objective 478, the first
flight of a collapsible Lower Body Negative Pressure unit.
In echocardiography, a probe next to the skin sends high frequency
sound waves (ultrasound) through the skin and into the body, then detects
reflections or echos from the surfaces of the organs, producing pictures.
The Life Sciences Division of NASA's Office of Space Science and
Applications is sponsoring the AFE which was developed at the Johnson
Space Center. Dr. Michael Bungo, the Director of JSC's Space Biomedical
Research Institute, is the Principal
Investigator.
CHARACTERIZATION OF NEUROSPORA
CIRCADIAN RHYTHMS
Characterization of Neurospora Circadian Rhythms (CNCR) in Space is
a middeck payload sponsored by the Office of Space Science and
Applications, Life Sciences Division. The objective of the CNCR experiment
is to determine if neurospora (pink bread mold) circadian rhythm (diurnal
cycles) persists in the microgravity environment of space.
This experiment is intended to provide information about endogenously
driven biological clocks, which might then be applied to other organisms.
Endogenous indicates the activity occurs within a single cell's outer
membrane.
Neurospora grows in two forms, a smooth confluence of silky threads
(mycelia) and cottony tufts of upright stalks tipped with tiny ball-shaped
spores (conidia). When growing in a constant, completely uniform external
environment, the neurospora mold cycles rhythmically from one growth
form to the other. This cycle causes the mold to produce the ball-shaped
spores on approximately 21-hour intervals. This interval is believed to be
controlled by an internal cell clock.
However, under typical circumstances, alterations in the external
environment, particularly day-night cycles with a period of 24 hours, are
capable of readjusting the neurospora internal clock. The fundamental
question addressed by this Shuttle experiment is whether the conditions of
space flight, especially the absence of Earth's strong gravitational field,
affect the neurospora's circadian rhythms. Because these rhythmic
phenomena also are found in all plants and animals, including humans,
this experiment addresses a broad and important biological question.
The Principal Investigator is Dr. James S. Ferraro, Southern Illinois
University, Carbondale, Ill. Project Manager is Dr. Randall Berthold at
NASA's Ames Research Center, Mountain View, Calif. Project Scientist is
Dr. Charles Winget, also at Ames. Program Scientist/Manager is Dr.
Thora Halstead, NASA Headquarters Life Sciences Division. Mission
Manager is Willie Beckham of NASA's Johnson Space Center, Houston.
PROTEIN CRYSTAL GROWTH EXPERIMENT
The Protein Crystal Growth (PCG) payload aboard STS-32 is a continuing
series of experiments that may prove a major benefit to medical technology.
These experiments could improve food production and lead to innovative
new drugs to combat cancer, AIDS, high blood pressure, organ transplant
rejection, rheumatoid arthritis and many other diseases.
Protein crystals, like inorganic crystals such as snowflakes, are
structured in a regular pattern. With a good crystal, roughly the size of a
grain of table salt, scientists are able to study the protein's molecular
architecture.
Determining a protein crystal's molecular shape is an essential step in
several phases of medical research. Once the three-dimensional structure
of a protein is known, it may be possible to design drugs that will either
block or enhance the protein's normal function within the body. Though
crystallographic techniques can be used to determine a protein's structure,
this powerful technique has been limited by problems encountered in
obtaining high-quality crystals well-ordered and large enough to yield
precise structural information.
Protein crystals grown on Earth are often small and flawed. The
problem associated with growing these crystals is analogous to filling a
sports stadium with fans who all have reserved seats. Once the gate opens,
people flock to their seats and in the confusion, often sit in someone else's
place. On Earth, gravity-driven convection keeps the molecules crowded
around the "seats" as they attempt to order themselves. Unfortunately,
protein molecules are not as particular as many of the smaller molecules
and are often content to take the wrong places in the structure.
As would happen if you let the fans into the stands slowly, microgravity
allows the scientist to slow the rate at which molecules arrive at their seats.
Since the molecules have more time to find their spot, fewer mistakes are
made, creating better and larger crystals.
During the STS-32 mission, 120 different PCG experiments will be
conducted simultaneously using as many as 24 different proteins. Though
there are three processes used to grow crystals on EarthQvapor diffusion,
liquid diffusion and dialysisQ only vapor diffusion will be used in this set of
experiments.
Shortly after achieving orbit, either Mission Specialist Marsha Ivins or
Mission Specialist David Low will combine each of the protein solutions
with other solutions containing a precipitation agent to form small droplets
on the ends of double-barreled syringes positioned in small chambers.
Water vapor will diffuse from each droplet to a solution absorbed in a
porous reservoir that lines each chamber. The loss of water by this vapor
diffusion process will produce conditions in the droplets that cause protein
crystals to grow.
In three of the 20-chambered, 15-by-10-by-1.5-inch trays, crystals will be
grown at room temperature (22 degrees Centigrade); the other three trays
will be refrigerated (4 degrees C) during crystal growth. STS-32 will be the
first mission during which PCG experiments will be run at 4 degrees C,
making it possible to crystalize a wider selection of proteins. The 9-day
flight also provides a longer time period for crystals to grow.
A seventh tray will be flown without temperature control. The crew will
videotape droplets in the tray to study the effects of orbiter maneuvers and
crew activity on droplet stability and crystal formation.
Just prior to descent, the mission specialist will photograph the droplets
in the room temperature trays. Then all the droplets and any protein
crystals grown will be drawn back into the syringes. The syringes then will
be resealed for reentry. Upon landing, the hardware will be turned over to
the investigating team for analysis.
Protein crystal growth experiments were first carried out by the
investigating team during Spacelab 2 in April 1985. These experiments
have flown six times. The first four flights were primarily designed to
develop space crystal growing techniques and hardware.
The STS-26 and STS-29 experiments were the first scientific attempts to
grow useful crystals by vapor diffusion in microgravity. The main
differences between the STS-26 and STS-29 payloads and those on previous
flights were the introduction of temperature control and the automation of
some of the processes to improve accuracy and reduce the crew time
required.
To further develop the scientific and technological foundation for protein
crystal growth in space, NASA's Office of Commercial Programs and the
Microgravity Science and Applications Division are co-sponsoring the STS-
32 experiments with management provided through Marshall Space Flight
Center, Huntsville, Ala. Blair Herren is the Marshall experiment
manager and Richard E. Valentine is the mission manager for the PCG
experiment at Marshall.
Dr. Charles E. Bugg, director of the Center for Macromolecular
Crystallography, a NASA-sponsored Center for the Development of Space
located at the University of Alabama-Birmingham, is lead investigator for
the PCG research team.

MICROGRAVITY RESEARCH WITH
THE FLUIDS EXPERIMENT APPARATUS
Fluids Experiment Apparatus
The Fluids Experiment Apparatus (FEA) is designed to perform
materials processing research in the microgravity environment of
spaceflight. Its design and operational characteristics are based on actual
industrial requirements and have been coordinated with industrial
scientists, NASA materials processing specialists and Space Shuttle
operations personnel. The FEA offers experimenters convenient, low-cost
access to space for basic and applied research in a variety of product and
process technologies.
The FEA is a modular microgravity chemistry and physics laboratory for
use on the Shuttle and supports materials processing research in crystal
growth, general liquid chemistry, fluid physics and thermodynamics. It
has the functional capability to heat, cool, mix, stir or centrifuge gaseous,
liquid or solid experiment samples. Samples may be processed in a variety
of containers or in a semicontainerless floating zone mode. Multiple
samples can be installed, removed or exchanged through a 14.1-by-10-inch
door in the FEA's cover.
Instrumentation can measure sample temperature, pressure, viscosity,
etc. A camcorder or super-8mm movie camera may be used to record
sample behavior. Experiment data can be displayed and recorded through
the use of a portable computer that also is capable of controlling
experiments.
The interior of the FEA is approximately 18.6-by-14.5-by-7.4 inches and
can accommodate about 40 pounds of experiment-unique hardware and
subsystems. The FEA mounts in place of a standard stowage locker in the
middeck of the Shuttle crew compartment, where FEA is operated by the
flight crew.
Modular design permits the FEA to be easily configured for almost any
experiment. Configurations may be changed in orbit, permitting
experiments of different types to be performed on a single Shuttle mission.
Optional subsystems may include custom furnace and oven designs,
special sample containers, low-temperature air heaters, specimen
centrifuge, special instrumentation and other systems specified by the
user. Up to 100 watts of 120-volt, 400-Hertz power is available from the
Shuttle orbiter for FEA experiments. The FEA was successfully flown on
two previous missions, as a student experiment on STS- 41D and as the first
flight of the JEA on STS-30.
Rockwell International, through its Space Transportation Systems
Division, Downey, Calif., is engaged in a joint endeavor agreement (JEA)
with NASA's Office Commercial Programs in the field of floating zone
crystal growth and purification research. The 1989 agreement provides for
microgravity experiments to be performed on two Space Shuttle missions.
Under the sponsorship of NASA's Office of Commercial Programs, the
FEA will fly aboard Columbia on STS-32. Rockwell is responsible for
developing the FEA hardware and for integrating the experiment payload.
Johnson Space Center, Houston, has responsibility for developing the
materials science experiments and for analyzing their results.
The Indium Corporation of America, Utica, N.Y., is collaborating with
NASA on the experiments and is providing seven indium samples to be
processed during this mission. NASA provides standard Shuttle flight
services under the JEA.
Floating Zone Crystal Growth and Purification
The floating zone process is one of many techniques used to grow single
crystal materials. The process involves an annular heater that melts a
length of sample material and then moves along the sample. As the heater
moves (translates), more of the polycrystalline material in front of it melts.
The molten material behind the heater will cool and solidify into a single
crystal.
The presence of a "seed" crystal at the initial solidification interface
will establish the crystallographic lattice structure and orientation of the
single crystal that results. Impurities in the polycrystalline material will
tend to stay in the melt as it passes along the sample and will be deposited
at the end when the heater is turned off and the melt finally solidifies.
Under the influence of Earth's gravity, the length of the melt is
dependent upon the density and surface tension of the material being
processed. Many industrially important materials cannot be successfully
processed on Earth because of their properties. In the microgravity
environment of spaceflight, there is a maximum theoretical molten zone
length which can be achieved.
Materials of industrial interest include selenium, cadmium telluride,
gallium arsenide and others. Potential applications for those materials
include advanced electronic electro-optical devices and high-purity feed
stock. Zone refining to produce ultra-high purity indium also is of interest
for the production of advanced electronic devices from indium antimonide
and indium arsenide.
FEA-3 Experiment Plan
The FEA-3 microgravity disturbances experiment involves seven
samples (plus one spare) of commercial purity indium (99.97 percent
purity). Indium was chosen for this experiment because it is a well-
characterized material and has a relatively low melting point (156 degrees
Celsius). The samples each will be 1 centimeter in diameter and 18
centimeters long and will be processed in an inert argon atmosphere. The
sample seeding heater translation rates and process durations are provided
in the following table:
Experiment Samples and Parameters
Heater Rate Duration
Sample Seeded (cm/hour) (hours)
1 No 0 2.00
2 Yes 24 4.50
3 Yes 12 9.00
4 Yes 24 4.50
5 Yes 48 2.25
6 Yes 12 9.00
7 Yes 96 1.10
At 5.25 hours mission elapsed time (MET), the flight crew will unstow
the FEA and connect its computer and support equipment. The samples
will be sequentially installed at 20, 26, 44, 66, 97, 114 and 144 hours MET and
processed.
The experiment parameters (heater power and translation rate) will be
controlled by the operator through the FEA control panel. Sample behavior
(primarily melt-zone length and zone stability) will be observed by the
operator and recorded using the on-board camcorder. Experiment data
(heater power, translation rate and position, experiment time, and various
experiment and FEA temperatures) will be formatted, displayed to the
operator and recorded by the computer. The operator will record the MET
at the start of each experiment and significant orbiter maneuvers and other
disturbances that occur during FEA operations. In addition, accelerometer
measurements during the induced disturbances will be recorded for
postflight analysis.
In general, the experiment process involves installing a sample in the
FEA, positioning the heater at a designated point along the sample, turning
on the heater to melt a length of the sample, starting the heater translation
at a fixed rate and maintaining a constant melt-zone length. When the
heater reaches the end of the sample, it is turned off, allowing the sample to
completely solidify, and the heater's translation is reversed until it reaches
the starting end of the sample. The sample 8mm camcorder cassette and
computer disk with the experiment data then can be changed and the next
experiment started.
FEA-3 Experiment Description
Most materials are processed in space to take advantage of the low
gravity levels achievable in low-Earth orbit, which has been demonstrated
to produce superior quality crystals over those grown on the ground. The
focus of the FEA-3 experiment entitled "Microgravity Disturbances
Experiment," is to investigate the effects of both orbiter and crew-induced
disturbances in the microgravity environment on the resulting
microstructure of float-zone-grown indium crystals.
The FEA-3 experiment is one of the first designed specifically to grow
crystals during known disturbances to investigate their effects on crystal
growth processes. The disturbances to be investigated in this experiment
will focus on orbiter engine firings and crew exercise on the treadmill, but
will include several other disturbances typical of orbiter operations. This
research should provide information useful in establishing the
microgravity-level requirements for processing materials aboard Space
Station Freedom and also provide a greater understanding of the role of
residual gravity in materials processing.
This experiment will also investigate the effects of disturbances on the
stability of a freely suspended molten zone and provide information on the
impurity refining capability of float zone processing in space.
MESOSCALE LIGHTNING EXPERIMENT
Space Shuttle mission STS-32 will again carry the Mesoscale Lightning
Experiment (MLE), designed to obtain nighttime images of lightning to
better understand the global distribution of lightning, the relationships
between lightning events in nearby storms and relationships between
lightning, convective storms and precipitation.
A better understanding of the relationships between lightning and
thunderstorm characteristics can lead to the development of applications in
severe storm warning and forecasting and in early warning systems for
lightning threats to life and property.
In recent years, NASA has used the Space Shuttle and high-altitude U-2
aircraft to observe lightning from above convective storms. The objectives of
these observations have been to determine some of the baseline design
requirements for a satellite-borne optical lightning mapper sensor; study
the overall optical and electrical characteristics of lightning as viewed from
above the cloud top and to investigate the relationship between storm
electrical development and the structure, dynamics and evolution of
thunderstorms and thunderstorm systems.
The MLE began as an experiment to demonstrate that meaningful,
qualitative observations of lightning could be made from the Shuttle.
Having accomplished this, the experiment is now focusing on quantitative
measurements of lightning characteristics and observation simulations for
future space-borne lightning sensors.
Data from the MLE will provide information for the development of
observation simulations for an upcoming polar platform and Space Station
instrument, the Lightning Imaging Sensor. The lightning experiment also
will be helpful for designing procedures for using the Lightning Mapper
Sensor, planned for several geostationary platforms.
The Experiment
The Space Shuttle payload bay camera will be pointed directly below the
orbiter to observe nighttime lightning in large, or mesoscale, storm systems
to gather global estimates of lightning as observed from Shuttle altitudes.
Scientists on the ground will analyze the imagery for the frequency of
lightning flashes in active storm clouds within the camera's field of view,
the length of lightning discharges and cloud brightness when illuminated
by the lightning discharge within the cloud.
If time permits during missions, astronauts also will use a handheld
35mm camera to photograph lightning activity in storm systems not
directly below the Shuttle's orbital track.
Data from the MLE will be associated with ongoing observations of
lightning made at several locations on the ground, including observations
made at facilities at the Marshall Space Flight Center, Huntsville, Ala.;
Kennedy Space Center, Fla.; and the NOAA Severe Storms Laboratory,
Norman, Okla. Other ground-based lightning detection systems in
Australia, South America and Africa will be integrated when possible.
The MLE is managed by NASA's Marshall Space Flight Center. Otha
H. Vaughan Jr., is coordinating the experiment. Dr. Hugh Christian is
the project scientist and Dr. James Arnold is the project manager.
IMAX
The IMAX project is a collaboration between NASA and the Smithsonian
Institution's National Air and Space Museum to document significant
space activities using the IMAX film medium. This system, developed by
the IMAX Systems Corp., Toronto, Canada, uses specially designed 70mm
film cameras and projectors to record and display very high definition
large-screen color motion pictures.
IMAX cameras previously have flown on Space Shuttle missions 41-C,
41-D and 41-G to document crew operations in the payload bay and the
orbiter's middeck and flight deck along with spectacular views of Earth.
Film from those missions form the basis for the IMAX production, The
Dream is Alive.
In 1985, during Shuttle Mission STS-61-B, an IMAX camera mounted in
the payload bay recorded extravehicular activities in the EASE/ACCESS
space construction demonstrations.
So far in 1989, the IMAX camera has flown twice, during Shuttle
missions STS-29 in March and STS-34 in October. During those missions,
the camera was used to gather material for an upcoming IMAX production
entitled The Blue Planet.
During STS-32, IMAX will film the retrieval of the Long Duration
Exposure Facility and collect additional material for upcoming IMAX
productions.
AIR FORCE MAUI OPTICAL SITE
CALIBRATION TEST (AMOS)
The Air Force Maui Optical Site (AMOS) tests allow ground-
based electro-optical sensors located on Mount Haleakala, Maui, Hawaii, to
collect imagery and signature data of the orbiter during overflights of that
location. The scientific observations made of the orbiter while performing
reaction control system thruster firings, water dumps or payload bay light
activation, are used to support calibration of the AMOS sensors and the
validation of spacecraft contamination models. The AMOS tests have no
payload-unique flight hardware and only require that the orbiter be in a
pre-defined attitude operations and lighting conditions.
The AMOS facility was developed by the Air Force Systems Command
(AFSC) through its Rome Air Development Center, Griffiss Air Force Base,
N.Y., and is administered and operated by the AVCO Everett Research
Laboratory in Maui. The principal investigator for the AMOS tests on the
Space Shuttle is from AFSC's Air Force Geophysics Laboratory, Hanscom
Air Force Base, Mass. A co-principal investigator is from AVCO.
Flight planning and mission support activities for the AMOS test
opportunities are provided by a detachment of AFSC's Space Systems
Division at Johnson Space Center. Flight operations are conducted at JSC
Mission Control Center in coordination with the AMOS facilities located in
Hawaii.
LATITUDE-LONGITUDE
LOCATOR EXPERIMENT
On Shuttle mission 41-G, Payload Specialist and oceanographer Scully
Power observed numerous unusual oceanographic features from orbit but
was unable to determine their exact locations for subsequent study. NASA,
in conjunction with the Department of Defense, began work on an
instrument that would be able to determine the precise latitude and
longitude of objects observed from space.
The Latitude-Longitude Locator (L3) was developed and flown on a
previous Space Shuttle mission. This flight will continue tests to determine
the accuracy and usability of the system in finding the latitude and
longitude of known ground sites.
L3 consists of a modified Hasselblad camera equipped with a wide-angle
40 mm lens, a camera computer interface developed by JSC engineers and
a Graphics Retrieval and Information Display (GRID) 1139 Compass
Computer.
Crew members will take two photographs of the same target at an
interval of approximately 15 seconds. Information will be fed to the GRID
computer, which will compute two possible locations. The crew, by
knowing whether the target is north or south of the flight path, will be able
to determine which of the two locations is correct and the target's latitude
and longitude.
Andy Saulietis of NASA's Johnson Space Center is the Principle
Investigator for the experiment.
SPACEFLIGHT TRACKING
AND DATA NETWORK
Primary communications for most activities on STS-32 will be conducted
through the orbiting Tracking and Data Relay Satellite System (TDRSS), a
constellation of three communications satellites, two operational and one
spare, in geosynchronous orbit 22,300 miles above the Earth. In addition,
three NASA Spaceflight Tracking and Data Network (STDN) ground
stations and the NASA Communications Network (NASCOM), both
managed by Goddard Space Flight Center, Greenbelt, Md., will play key
roles in the mission.
Three stationsQMerritt Island and Ponce de Leon, Fla., and BermudaQ
serve as the primary communications facilities during the launch and
ascent phases of the mission. For the first 80 seconds, all voice, telemetry
and other communications from the Space Shuttle are relayed to the
mission managers at Kennedy and Johnson Space Centers by Merritt
Island.
At 80 seconds, the communications are picked up from the Shuttle and
relayed to the two NASA centers from Ponce de Leon, 30 miles north of the
launch pad. This facility provides the communications between the Shuttle
and the centers for 70 seconds, or until 150 seconds into the mission. This
is during a critical period when exhaust from the solid rocket motors
"blocks out" the Merritt Island antennas.
Merritt Island resumes communications with the Shuttle after those 70
seconds and maintains communications until 6:30 after launch, when
communications are "switched over" to Bermuda. Bermuda then provides
the communications until 11 minutes after lift off when the TDRS-East
satellite acquires the Shuttle. TDRS-West acquires the orbiter at launch
plus 50 minutes.
Communications will alternate between the TDRS-East and TRDS-West
satellites as the Shuttle orbits the Earth. The two satellites will provide
communications with the Shuttle during 85 percent or more of each orbit.
The TDRS-West satellite will handle communication with the Shuttle
during its descent and landing phases.

In article <37350@ames.arc.nasa.gov> Our Favorite Agency sez: [ The Latitude Longitude Locator includes ] > ... a camera computer interface developed by JSC engineers and >a Graphics Retrieval and Information Display (GRID) 1139 Compass >Computer. Though we may lag behind the Soviets in the mundane, yucky _flight hardware_ part of the space race, nobody can lay a glove on our lead in _acronyms_. We can even reverse engineer an acronym when needed! In this case, the GRiD Systems Inc. Compass computer, selected by the National Acronym Stockpile Authority (NASA) for auxiliary middeck computing since 1981 -- but inconveniently innocent of acronymic origins itself (its inventor was a mariner and just meant "map grid") -- gets spruced up with something nicely nonsensical. (_Graphics retrieval and information display_? Are the graphics stored somewhere? Does that parse as "retrieval and information" or "retrieval and display"?) I guess it's a good thing they didn't buy a Panasonic, huh. -- War is like love; it always \%\%\% Tom Neff finds a way. -- Bertold Brecht %\%\%\ tneff@bfmny0.UU.NET
