3/15/93: CATARACT SUFFERERS COULD BENEFIT FROM SPACE TECHNOLOGY
Charles Redmond
Headquarters, Washington, D.C. March 15, 1993

Lewis Research Center, Cleveland
RELEASE: 93-45
Thousands of potential cataract sufferers may benefit from technology
development now underway by researchers at NASA's Lewis Research Center,
Cleveland, Ohio. A recently developed, Lewis diagnostic tool may lead to
treatment of cataracts while they are in the early formative stages.
According to Dr. Rafat Ansari, project scientist at the Lewis center,
"Once a series of voluntary patient studies is completed using this prototype
tool, pharmaceutical companies then may have the opportunity to develop the
necessary drugs to neutralize a developing cataract."
The tool is a small, fiber optic probe that can detect protein crystals
suspended in the fluid inside the eye's lens. These crystals are suspected of
forming into a cloudy mass over time, thus causing cataracts.
"Until now," according to Ansari, "physicians have not had the
technology to tell what is really happening inside the lens." Along with
Professor Harbans Dwadwal of the State University of New York at Stoneybrook,
Ansari has developed an instrument that uses laser light to detect cataracts in
the very early formative stages.
An optical fiber transmits a low-power laser beam which is scattered
inside the eye with the reflections picked up by a return fiber optical path.
The reflected light returned through the optical path is sampled by a light
detector inside the small device. The laser light is very weak so there is no
risk to eye damage from the laser.
The electrical signal from the detector is fed to a laptop computer
where it is analyzed and where it also could be stored permanently. A change
in protein particle size might indicate the onset of a cataract.
Ansari points out that fiber optic probes also can measure the sizes of
very small particles that are suspended in solutions. This capability may have
use in industrial applications as well as in the field of ophthalmology.
Originally developed for an experiment in materials processing aboard
the Space Shuttle, the diagnostic tool is small enough to fit in a shirt
pocket.
Ansari is a research professor at Cleveland's Case Western Reserve
University who works as a project scientist for the Lewis Research Center under
a Case Western Reserve-NASA cooperative research program. He currently is
assigned to Lewis' Materials Division.

SPECIAL TOPICS:
(STS-55)
The highest wind at the Shuttle Landing Facility on Saturday
was 63 mph and at Pad 39-A the peak gust was 71 mph. While the
high wind precluded any work by the launch team from the pad
structures on Saturday, there was no damage to the vehicle and
only minor damage in the area surrounding the launch pad. During
the day Saturday the Complex 39 freeze protection plan was
implemented and Columbia's heaters were turned on. The lowest
temperature over the weekend was 32 degrees on Sunday.
(STS-56)
Discovery's rollout from the Vehicle Assembly Building to
Launch Pad 39-B began at 7:28 a.m. this morning. The astronauts
are scheduled to arrive at 3:30 p.m. this afternoon to begin the
required launch pad safety training and for the Terminal
Countdown Demonstration Test which will be conducted on Wednesday
and Thursday.
(STS-57)
In OPF Bay 1, the astronauts completed the Crew Equipment
Interface Test (CEIT) for Endeavour on Saturday. The payload bay
doors are scheduled to be closed on Thursday. Rollover to the
VAB is currently planned to occur on March 25.

NASA managers have set March 21, 1993, as the launch date for Shuttle mission
STS-55. Space Shuttle Columbia and her 7 member crew will fly a mission which
is primarily dedicated to the German Space Agency. The major payload for
STS-55, the pressurized spacelab module or Spacelab-D2, will allow the
astronauts to perform a wide range of experiments in the microgravity
environment of space flight.
Columbia's crew will be divided into two teams who will each work a 12-hour
shift so that science operations can be carried out around the clock. The
STS-55 mission is scheduled to last 9 days and will conclude with a landing at
Kennedy Space Center, Fla.
* * * * * * * * * * * * * * * *
Because Columbia's launch date was rescheduled, Shuttle mission STS-56 is now
targeted for launch around April 7, 1993. Space Shuttle Discovery will carry
the ATLAS-2 payload, and mission duration is planned for 8 days.
Technicians at the Kennedy Space Center have rolled out Discovery to the launch
pad and continue to prepare Discovery for an early April launch.
* * * * * * * * * * * * * * * *
Work on Endeavour is continuing as scheduled. Technicians have installed the
Spacehab-1 and will soon begin the Spacehab closeouts. Workers at the Kennedy
Space Center also will begin closing out the orbiter mid-deck this week.
Space Shuttle mission STS-57 is scheduled for launch in late April. Endeavour
and her 6 member crew is scheduled to fly a 7-day mission.

MGN STATUS 3/12-15, 1993
Magellan Status
Status Report of Magellan for Friday, March 12, 1993:
1. The Magellan spacecraft is operating normally, as it approaches its 7000th
orbit of Venus next Tuesday. (For those of you who have access to orbit numbers
and are confused by the difference between the current orbit number and this
count, remember that the first orbit after Venus Orbit insertion was 100 and an
adjustment during the in-orbit-check-out added another 11.)
2. The swath one starcals continue to produce attitude updates which average
0.1 deg. This is higher than the normal setting of the innovation bound. The
swath two starcals (which scan the same two stars in the opposite direction)
result in updates which average only 0.01 deg. The limit is presently widened
to 0.2 deg.
3. Yesterday spacecraft controllers uplinked the G3071 command sequence which
will control the spacecraft for the next four weeks. It went active at 9:33 AM
PST today and is very similar to the last several command sequences.
4. The spacecraft performs a reaction wheel desaturation on every orbit, a
starcal on every other orbit. The High Gain Antenna is kept pointed toward
Earth (except during the starcal) in order to acquire gravity data, especially
around periapsis. Engineering telemetry is being received at 1200 bps.
5. The Magellan Project continues to implement the plan with the MESUR
Pre-project to collocate 50 MESUR members on the second floor of Bldg. 230,
with minimal impact to MGN preparations for TEX and LMGT. Several MGN team
members have moved this week, and the remaining moves will be complete by March
31st.
6. Magellan has completed 6966 orbits of Venus since August 10, 1990.
Magellan is 74 days from the end of Cycle-4.
Magellan Status
Status Report of Magellan for Monday, March 15, 1993:
1. The Magellan spacecraft continues to operate normally, gathering gravity
data in its fourth 243-day cycle of Venus.
2. Magellan has completed 7989 orbits of Venus since August 10, 1990.
3. The spacecraft has traveled about 258 million kilometers (160 million
miles) in its orbits around Venus, in addition to the 400 million kilometers
(248 million miles) it traveled getting from Earth to Venus.
Magellan is 71 days from the end of Cycle-4.
