SCIENTIFIC
OUTLOOK
2001:
A Year of Challenge and Accomplishment for NASA
By
Bob Jacobs, 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 became the largest and most sophisticated
spacecraft ever built, and 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 presidents. During the transition
period, 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 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 year-long 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. It's
the first science lab delivered to the orbiting science
station. The space station is now the most complex and
most 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 the
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.
