2001: A YEAR OF CHALLENGE AND ACCOMPLISHMENT
FOR NASA
As NASA's space
odyssey for 2001 comes to an end, the Agency faces a year of transition
and new challenges as it prepares to continue its mission of discovery
into the new millennium.
In the last year,
the International Space Station, the largest and most sophisticated
spacecraft ever built, celebrated its first full year of human habitation.
The successful arrival of NASA's Mars Odyssey at the red planet energized
space scientists and, for the first time, NASA was able to create a
complete biological record of Earth.
In 2001, the Space
Shuttle turned 20 as NASA launched a new initiative to find better and
cheaper access to space, all while facing new fiscal realities that
could fundamentally change the way the agency does business.
"The people
of NASA have much of which to be proud as we reflect on the agency's
accomplishments in 2001," said Acting Administrator Dr. Daniel
R. Mulville. "Our future challenges are formidable, but our resolve
to overcome those challenges is equally intense. In 2002, NASA will
continue its mission to expand air and space frontiers with renewed
vigor."
CHANGE OF NASA LEADERSHIP
For the first time
in nearly a decade, NASA will have new leadership. President George
W. Bush nominated Sean O'Keefe, the Deputy Director of the Office of
Management and Budget, to be the agency's new Administrator. Daniel
S. Goldin, the longest-serving Administrator in NASA's history, resigned
in November after serving more than nine years under three American
presidents. During the transition, Mulville, NASA's Associate Deputy
Administrator was appointed Acting Administrator.
FLAGS FOR HEROES AND FAMILIES
The tragic events
of September 11 brought the nation together with a new sense of pride
and determination. Expedition Three commander Frank Culbertson was the
only American not on Earth the day of the attacks and documented visible
signs of the destruction from the International Space Station. To honor
those heroes killed and seriously hurt in New York, Washington and Pennsylvania,
NASA sent more than 6,000 American flags into space aboard the Space
Shuttle Endeavour. The flags will be distributed to the victims and
their families.
NASA'S MARS PROGRAM SEES RED
The agency's Mars
exploration program rebounded in 2001 when Mars Odyssey successfully
entered orbit around the red planet following a six-month, 286-million
mile journey. NASA's Mars Global Surveyor sent back its 100,000th image
of the Martian surface. The orbiter has been snapping dramatic and images
for four years. In 2001, Mars Global Surveyor, in tandem with the Hubble
Space Telescope, had a ringside seat to the largest global dust storm
on the Martian surface seen in decades.
THE SEARCH FOR UNIVERSAL LIFE
Is there life on
another world? In 2001, astronomers using the Hubble Space Telescope
measured the atmosphere of a planet outside our solar system. Astronomers
funded by NASA and the National Science Foundation discovered eight
new extrasolar planets that have circular orbits, similar to the orbits
of planets in our own solar system. Also, NASA's Submillimeter Wave
Astronomy Satellite provided the first evidence that there are water-bearing
worlds beyond our solar system.
REMOTE SENSING SEES A CLIMATE CHANGE
NASA announced
the creation of the first complete "biological record of Earth"
by using data from NASA's Sea-viewing Wide Field-of-View sensor. Researchers
also suggested the Earth is becoming a greener greenhouse, determining
that plant life in the northern latitudes has been growing more vigorously
since 1981. In February, NASA released a new map of Antarctica made
from Radarsat data. Using the new maps and comparing them to maps produced
in 1981, scientists will track Antarctic ice changes, a key to understanding
our global environment and climate change. In 2001, NASA research also
suggested that desert dust in the atmosphere over Africa might actually
inhibit rainfall in the region, contributing to drought conditions.
NASA COMES DOWN TO EARTH
In 2001, NASA announced
a commercial partnership that will allow placement of advanced global
positioning technologies in farm equipment. The technology will be used
to help farmers navigate fields in poor weather and at night. Throughout
the summer of 2001, NASA satellites tracked the devastating spread of
wildfires around the western United States, helping federal, state and
local governments mitigate these natural disasters.
NASA RESEARCH BENEFITS LIFE ON EARTH
Using lasers developed
by NASA, researchers discovered a way to bring a beam of light to a
stop, store it, and then send it on its way. The discovery could lead
to next-generation technologies, such as increasing the speed of computers.
A revolutionary early breast cancer detection tool based on NASA technology
began human clinical trials in November. The technology may one day
allow physicians to diagnose tumors without surgery. In 2001, NASA and
the National Cancer Institute began a three-year program to explore
new biomedical technologies to develop and study microscopically small
sensors that can detect changes at the cellular and molecular level.
SOLAR SYSTEM EXPLORATION NEARS PERFECTION
NASA's Near-Earth
Asteroid Rendezvous Shoemaker spacecraft did something it wasn't designed
to do when mission managers gently landed the spacecraft on the asteroid
Eros after a yearlong orbital mission. In a risky fly-by maneuver, the
Deep Space 1 spacecraft successfully navigated past a comet, giving
researchers an unprecedented view inside the glowing core of icy dust
and gas. During 2001, a NASA-funded research team presented evidence
that Earth's most severe mass extinction, an event 250 million years
ago that wiped out 90 percent of life, was triggered by a collision
with a comet or an asteroid.
HUMAN SPACE FLIGHT PROGRAMS REACH MILESTONES
Celebrating its
first full year of human habitation, the International Space Station's
research odyssey began in 2001 with the launch of the Destiny module,
the first science lab delivered to the station. The space station is
now the most complex and powerful spacecraft ever built. Facing financial
challenges in the coming years, an independent task force produced a
report that is expected to help managers get the program back on track.
The construction of the International Space Station is made possible
by NASA's robust fleet of Space Shuttles. The Shuttle celebrated its
20th anniversary in 2001, having carried more than three million pounds
of cargo and more than 600 passengers into space.
FUTURE NASA TECHNOLOGY TODAY
In 2001, NASA launched
an ambitious multi-billion-dollar initiative designed to develop the
technologies needed to build a second-generation reusable launch vehicle.
NASA's Space Launch Initiative, or SLI, will also identify 21st-century
designs that can provide safer, more reliable and less expensive access
to space. Instead of rocket fuel, NASA's propeller-driven Helios aircraft
used solar energy to help set a world record altitude of 96,500 feet.
NASA researchers also tested a revolutionary cockpit display that will
offer pilots an electronic picture of what is outside their windows,
no matter the weather or time of day. This Synthetic Vision will show
terrain, ground obstacles, air traffic and other important data to the
flight crew.
