Three, two, one, and we have
liftoff...as the Space Shuttle heads for Earth orbit from the
John F. Kennedy Space Center, America's premier spaceport. On
April 19, 2001, Kennedy celebrated the 20th anniversary of the
first Shuttle launch with the launch of STS-100 on Endeavour.
During the past 20 years, the Shuttle has transported approximately
three million pounds of cargo, and hundreds of astronauts have
had the unique privilege of traveling aboard this unrivaled space
vehicle. At the same time, more than 100 modifications have been
made to make the Shuttle safer and more efficient and reliable,
as well as to expand its capabilities. Shuttle upgrades include
a "glass cockpit," composed of 11 new, full-color,
flat-panel displays on the flight deck; a relocated airlock to
prepare for International Space Station (ISS) assembly flights;
an updated communications system; and better protection elements
for the orbiter's cooling system.
Weather is very important to
the Shuttle program. Because Florida is known as "the lightning
capital of the U.S.," lightning detection systems play an
important role at Kennedy. A technology that determines the ground
strike point of lightning in the immediate vicinity of the shuttle
launch pads is valuable in determining which electronic equipment
or system needs to be retested following a lightning strike.
The lightning detector technology has commercial potential in
sensitive manufacturing facilities, missile storage facilities,
or hazardous chemical storage bunkers.
As NASA's designated Center of
Excellence in launch and payload processing systems, Kennedy's
primary responsibilities include Space Shuttle processing, the
acquisition and management of Expendable Launch Vehicle launch
services, payload carriers, payload processing, and support.
Kennedy's Spaceport Technology Center (STC) initiative is an
evolving component of Kennedy's dual mission in Space Launch
Operations and Spaceport and Range Technologies. The STC is designed
to align and enhance existing Kennedy technology development
product lines with the needs of current and future reusable and
expendable space transportation systems and their payloads. Kennedy
has established unique development capabilities (personnel and
laboratory/test bed facilities) for collaborative technology
development efforts in several technology thrust areas called
spaceport technology development initiatives (STDIs). The STDIs
are: fluid system technologies, spaceport structures and materials,
process engineering, range technologies, and command, control,
and monitoring technologies. Kennedy also has product lines for "spaceport design and systems development," which
test and integrate an array of component technologies in order to
build and deploy an operational spaceport system. Kennedy's complementary
advanced spaceport technologies and systems will benefit current
and future spaceports on Earth and beyond.
An ongoing project at Kennedy
is a study of the extent to which electrostatic charge can be
generated and how it can accumulate on lunar soil and dust particles.
The findings of this research will provide critical information
and techniques for the successful operation of an extraterrestrial
spaceport by eliminating potential hazards relating to dust accumulation
on equipment surfaces, astronaut suits, solar panels, habitat
filters, thermal radiators, and other equipment. Dust accumulation
could lead to a loss in performance, or even render equipment
unusable. Commercial applications may be found in the antistatic,
paint, and grain industries.

As the quest
continues to construct an orbiting research facility, Kennedy
endeavors to help ensure safe and successful ground operations
for the ISS flight hardware. Kennedy successfully completed Phase
I of Multi Element Integrated Testing (MEIT), involving the U.S.
Laboratory Destiny, electrical power, control and communication
modules, a docking port, and the Canadian-built robot arm. Kennedy
teams focused their efforts on MEIT Phase II test planning and
completed the first MEIT II test configuration involving a Kennedy-developed
ground support U.S. Lab Emulator, additional power modules, and
the Mobile Transporter. One of the first payloads to reside on
the Station, the Protein Crystal Growth-Enhanced Gaseous Nitrogen
Dewar, was processed at Kennedy Space Center for flight STS-106.
It was returned from orbit on flight STS-92, demonstrating the
full cycle for ISS hardware performing research in space.
A technology has been developed
at Kennedy that may be beneficial to ISS and other Low-Earth
Orbit (LEO) vehicles such as the Space Shuttle, as well as long-duration
interplanetary vehicles and future planetary habitats. The personal
cabin pressure monitor warns, by means of audio, vibratory, and
visual alarms, of the impending danger of hypoxia when cabin
pressure has fallen to pre-programmed threshold levels. This
device can also be used in a variety of aviation, aerospace,
and non-aerospace applications where knowledge of one's exposure
to low partial pressure of oxygen is important.

Nitrogen Oxide Waste Conversion Scrubber installed at the oxidizer
farm on Launch Complex 39A at Kennedy Space Center. |
Due to its
location on the Merritt Island National Wildlife Refuge and its
biological diversity, Kennedy Space Center has developed a biological
sciences capability that includes spaceport ecosystem assessment.
Under the Endangered Species Act and the National Environmental
Policy Act, launch operations require evaluation and impact minimization.
Approximately 100 wildlife species found at Kennedy are the subject
of conservation concerns. Monitoring focuses on combining field
and remote sensing data with predictive/interpretive models on
marine turtles, gopher tortoises, indigo snakes, wading birds,
shorebirds, scrub jays, beach mice, and manatees. A technology
developed to reduce hazardous rocket-fuel waste has also resulted
in positive effects to the environment at Kennedy. The Nitrogen
Oxide Waste Conversion Scrubber converts hazardous waste to a
high-grade fertilizer, while reducing air pollution. Its commercial
applications include possible use in power plants.
As we move into the 21st century,
Kennedy Space Center faces many challenges. The strategic goals,
vision, and guiding principles developed at Kennedy mirror the
dedication, excellence, and integrity of investing in America's
future through continued space exploration.
