6/02/93: SHUTTLE TILE MATERIAL MAY HELP IN BONE TRANSPLANTS

RELEASE: 93-102
The same material that keeps the Space Shuttle from burning up when it
returns from space may be useful in treating medical problems on Earth.
Researchers from NASA's Ames Research Center, Mountain View, Calif., are
working with physicians from BioMedical Enterprises Inc. and the University of
Texas Health Science Center, both of San Antonio, to determine whether the
Space Shuttle's ceramic surface insulation materials can be used as an implant
for human skeletal reconstruction.
"We're still a long way from having a bone implant that's ready for human
use," said Howard Goldstein, Senior Staff Scientist in Ames' Thermosciences
Division. "But we have data that show the tile material has excellent promise
for use as a bone implant."
Goldstein led the research, development and evaluation of the ceramic,
known as Reusable Surface Insulation (RSI), in the 1970s and 1980s. He also
will lead Ames' RSI research team on the new project.
Tiles made of RSI cover the Space Shuttle and keep it from burning up when
it re-enters Earth's atmosphere. "The theoretical attraction of Shuttle
insulation is that it is biocompatible," said Dr. Dani Goldwater, Manager of
commercial space programs at Ames. "It also provides a porous framework, which
allows infiltration by normal bone cells and deposition of bone mineral. The
result could be complete integration of the implant into normal bone," she
said.
Goldstein cautioned, however, that "a lot remains to be done before we can
demonstrate the many potential uses of RSI as a bone implant." For example,
scientists must improve the material properties of the ceramic fiber composite.
They also will have to increase the pore size of the material for use as a bone
scaffolding, while increasing its strength and maintaining biocompatibility.
Dr. Casey Fox, BioMedical Enterprises Inc., and Dr. Thomas Aufdemorte,
University of Texas Health Science Center, first must determine the safety,
efficiency and applications for these materials as bone implants. After
developing and testing the product in the laboratory, they will work to get
U.S. Food and Drug
Administration approval for use in humans. Fox expects the development,
testing and market approval process to take about 6 years.
If tests are successful, "the ultimate result of this research might be
the production of implants that can substitute for or supplement natural bone,"
Fox said. "The contribution to the relief of human suffering is potentially
enormous."
Fox said physicians perform between 1.2 million and 1.7 million orthopedic
and dental procedures each year that could benefit from the availability of the
bone implant material. People with bone disorders resulting from trauma,
disease and degenerative skeletal changes associated with aging are likely to
benefit from successful development of this bone implant, he said.
"The successful development of RSI technology as a bone implant material
could lead to major improvements in the initial and long-term viability of bone
implants," Fox said. He expects the new bone implant to be used with implants
such as metal pins, wires, plates and screws when treating a fracture.
Physicians also may use it instead of bone transplanted from humans, thereby
preventing disease transmission.
"After healing within and around the porous implant, the result could be a
fiber-reinforced bone," Fox said. In addition, he expects the porosity and
surface chemistry of the ceramic material to allow administration of medicines
that promote bone healing.
RSI is a silica, alumina fiber and borosilicate glass composite that can
be adapted to mimic the structure of bone. Dr. Daniel Leiser, assistant chief
of Ames' Thermal Protection Materials Branch, will lead Ames' effort to refine
RSI for the bone implant study. The goal is to produce a high-purity, large
porosity, low-density, high-strength ceramic fiber composite.
"This research team combines the unique talents of three groups,"
Goldstein said. "The skills of Ames' Thermosciences Division in developing
composites and processes will join with university-based clinical medical
expertise and the biomaterials and implant design skills of private industry."
Ames scientists will develop processing methods to produce ceramics that
meet the requirements for pore size, strength and
biocompatibility. Fox and Aufdemorte will study the performance of ceramic
materials as implants in the laboratory, which may include experiments on
future Space Shuttle flights. They have shown that RSI materials appear to be
biocompatible and potentially useful for oral and general skeletal trauma and
reconstructive treatment.

% Astronaut candidate recruiting begins;
% The Postal Service's new space stamp;
% STS-57 mission update.
It is that time again. NASA is accepting applications for mission specialist
and pilot astronaut positions. Applications are being accepted until July 1,
1993.
After a 6-month process which includes screening, interviews and medical
evaluations, astronaut selections will be announced in the spring of 1994.
Those selected for the astronaut corps will be multi-talented individuals who
are outstanding in their chosen fields. They will also able to handle various
technical assignments and maintain spacecraft systems and experiments.
* * * * * * * * * * * * * * * *
On Thursday, June 3, 1993, at 12 a.m. EDT, the U.S. Postal Service will
present its latest space theme stamp at the Kennedy Space Center. The $2.90
stamp features the image of a futuristic space plane soaring through space,
leaving Earth and other interstellar objects in its celestial wake.
Popular space stamps of the past include a 1969 stamp commemorating the manned
lunar landing. Another favorite was a 1992 joint venture with Russia that
released four stamps depicting international cooperation in space exploration.

6/02/93: WIDE FIELD/PLANETARY CAMERA-2 SHIPPED TO GODDARD

The Jet Propulsion Laboratory's new Wide Field/Planetary Camera, designed
to replace the current camera on board NASA's orbiting Hubble Space Telescope,
was shipped yesterday from JPL, two years after major redesign changes began in
August 1991.
The camera will be delivered to the Goddard Space Flight Center in
Greenbelt, Md., where it will be tested with spacecraft and ground system
simulators before being shipped to Kennedy Space Center in Florida for
integration with the space shuttle, said Larry Simmons, WF/PC-2 program manager
at JPL.
"The Wide Field/Planetary Camera-2 was designed to restore nearly all of
the original imaging capability lost when an optical flaw was discovered in the
Hubble telescope's primary mirror," Simmons said. "We modified the camera's
internal relay optics and made several other design changes to enhance
WF/PC-2's overall imaging capability."
Four small relay mirrors inside the camera's four optical trains have been
polished to a new prescription that will cancel the error in the curvature of
the Hubble Space Telescope's primary mirror by creating an error of equal and
opposite magnitude, Simmons said.
Small actuators will fine-tune the alignment of these mirrors on orbit,
assuring the optical quality that will be required to image fine detail in star
clusters, distant galaxies and objects in the ultraviolet.
After the camera has been tested at Goddard, it will be delivered in
mid-September to Kennedy Space Center, where it will be readied for a Dec. 2,
1993 launch aboard the space shuttle Endeavour.
The camera is scheduled to be installed on the orbiting telescope on the
third day of astronaut extravehicular activities during STS-61, the first of
several Hubble Space Telescope servicing missions designed to replace major
components of the space telescope and science instruments.
About one month after installation, the new camera will be ready to begin
imaging science targets with its three wide-field camera systems and one
planetary camera system. The wide-field cameras will provide extraordinary
sensitivity for the detection of star clusters and distant galaxies, while the
planetary camera will perform high-resolution studies of individual objects,
including planets and their satellites, nearby galaxies and other stellar
objects.
WF/PC-2 will be able to detect objects 100 times fainter than those
visible from Earth-based telescopes, with about 10 times greater spatial
resolution. The camera also has the unique capability of imaging in the far
ultraviolet, a capability that is impossible from ground-based telescopes and
limited, at best, from space.
The Wide Field/Planetary Camera-2 was designed and built by the California
Institute of Technology's Jet Propulsion Laboratory for NASA's Office of Space
Science.
