2/08/93: ASTROPHYSICIST NAMED 1992 NASA INVENTOR OF THE YEAR

Headquarters, Washington, D.C. February 8, 1993

RELEASE: 93-024
A NASA astrophysicist whose work in developing x-ray telescopes led to his
invention of a revolutionary new microscope, has been named NASA Inventor of
the Year for 1992.
Richard B. Hoover of the Marshall Space Flight Center, Huntsville, Ala.,
was selected for his invention of the Water-Window Imaging x-ray Microscope.
This instrument should enable researchers to see in great detail high contrast
x-ray images of proteins, chromosomes and other tiny carbon structures inside
living cells. Resolution of the microscope could be so high that it may
produce detailed images of the building blocks of life -- tiny DNA molecules.
"I believe the microscope has immense potential in many biological and
medical research areas," Hoover said. These include genetic and gerontology
research; gene splicing and genetic engineering; cancer research and early
tumor cell diagnostic imaging; AIDS research including analysis of the viral
structure of HIV and assessment of real time interactions of influencing drugs
and antibodies; and chemical drug analysis.
The device uses x-rays instead of visible light to create ultra-high
resolution, high-contrast images.
Will See Things Never Seen Before
The Microscope got its "water-window" name because it is designed to
operate in a narrow band of the x-ray part of the electromagnetic spectrum at
which water transmits or passes x-rays and appears transparent, and carbon
absorbs x- rays and becomes opaque. In this "window" between 23.3 and 43.7
angstroms, the microscope can produce detailed images of the important carbon
structures inside a living cell, which is made up primarily of water.
Above this "window," carbon becomes more transparent to x-rays so carbon
structures will not show up. Below the "window," water absorbs x-rays and
becomes opaque, obscuring the carbon structures inside the cell.
"This instrument essentially will allow us to see through the water and
into the living cell with very high resolution and high contrast, without using
dyes or stains which produce limitations," explained Hoover. "When development
is complete and cell biologists begin using the microscope, it is possible that
they will begin seeing things they have never seen before."
The advance in capability provided by the microscope may be as great as
the difference between a doctor looking at a conventional photograph and a
doctor looking at an x-ray picture of the human body, according to Hoover.
Hoover is a member of the Solar-Terrestrial Physics Division of the
Marshall Center's Space Science Laboratory. A veteran of 27 years with the
center, his primary research has been devoted to development of advanced x-ray
imaging systems. He has contributed significantly to improved technologies for
x-ray optics.
Most recently, he was instrumental in the development of a new kind of
solar x-ray telescope. Launched aboard sounding rockets in 1987 and 1991, the
solar x-ray telescopes have produced some of the highest resolution x-ray
images ever taken of the sun. Hoover found that the new optics technologies
developed for this x-ray telescope could be applied to the development of a
high resolution x-ray microscope.
In addition to his work at NASA, Hoover has devoted time to research in
other disciplines. He is an internationally recognized authority on
photomicroscopy and the micropaleontology of diatoms (a microscopic single-cell
algae).
He graduated with honors from Henderson State University in Arkadelphia,
Ark., in 1964 with a bachelor of science degree in physics and mathematics. He
was a physics instructor at the University of Arkansas from 1965 to 1966 and
later studied optics at the University of California at Los Angeles and the
University of Alabama in Huntsville. He is married to the former Miriam
Jackson.
Hoover was selected to receive the Inventor of the Year Award by NASA's
General Counsel Office, Headquarters, Washington, D.C.

Kennedy Space Center management is holding its launch readiness review today
for Columbia and the STS-55 D-2 Spacelab mission. The formal Flight Readiness
Review by NASA Office of Space Flight management will be held at KSC this
Thursday, Feb. 11. The launch dress rehearsal with the astronaut and ground
launch team crews -the Terminal Countdown Demonstration Test-will begin on
Thursday, Feb. 11, and conclude with a simulated launch at 11:00 am EST on
Friday, Feb. 12.
Launch processing of Columbia has returned to its nominal schedule. This could
allow for the launch of the Columbia mission later this month-tentatively Feb.
25. The STS-55 mission is the second dedicated German research flight; the
first was the D-1 mission which flew on STS-61A in November 1985. This flight
is scheduled as an 8-day and 22-hour, seven-crewmember mission with the
Spacelab long module and a variety of scientific discipline investigations.
This mission's major Spacelab facilities will continue the exploration of fluid
physics and human physiological changes in microgravity.
Because this is a dedicated German mission, the operations control center for
much of the Spacelab equipment will be near Munich. Communications with the
equipment and payload specialist crew will be much the same, though, as if the
payload control center were at Huntsville or Greenbelt.
The mission is slated for a landing at the Kennedy Space Center Shuttle Landing
Facility at mission's end, nominally March 6 for a Feb. 25 launch.

NASA flight management has added a spacewalk to the STS- 51 mission aboard
Discovery, now set for a July launch to deploy the Advanced Communications
Technology Satellite and to deploy and retrieve the ORFEUS ultraviolet
spectrometer on the SPAS sub-satellite system. The addition of this spacewalk
adds to the series of spacewalks NASA has performed which allow for the
continual refinement of human performance capabilities and the continual
expansion of knowledge concerning human performance limitations, all of which
are important baseline considerations in preparations for the manufacture,
launch and assembly of Space Station Freedom components.

A commercial suborbital rocket carrying 7 experiments has been scheduled for
launch on Friday, Feb. 19, at 1:00 pm EST at the White Sands Missile Range. The
launch is sponsored by the University of Alabama in Huntsville's Consortium for
Materials Development in Space (a NASA Center for the Commercial Development of
Space).
EER Systems, Corp., Vienna, VA, will launch a Consort 6 vehicle for the
consortium. The rocket will carry the payloads to an altitude of 200 miles
providing about 8 minutes of microgravity exposure. Several of the experiments
will investigate several different material properties involving metallic and
non-metallic compounds. Other experiments will investigate the potential of
microgravity to improve the purification process for biological materials.
