| NASA - Topex / Poseidon Oceanography Mission Ends |
 |
The joint NASA/Centre National d'Etudes
Spatiales Topex/Poseidon oceanography
satellite ceased operations after nearly
62,000 orbits of Earth. The spacecraft lost
its ability to maneuver, bringing to a close
a successful 13-year mission.
Topex/Poseidon data have helped in hurricane
and El Nino/La Nina forecasting, ocean and
climate research, ship routing, offshore
industries, fisheries management, marine
mammals' research, modernizing global tide
models and ocean debris tracking.
The satellite's pitch reaction wheel, which
helps keep the spacecraft in its proper
orbital orientation, stalled on October 9,
and ground controllers concluded the wheel
was not functioning. The satellite remains in
orbit 1,336 kilometers (830 miles) above the
Earth, posing no threat to the planet.
Topex/Poseidon's data have been the subject
of more than 2,100 research publications;
major science and application achievements
include:
- the first decade-long global descriptions
of seasonal and yearly ocean current changes
- refined scientists' estimates of rising
global sea level during the past decade
- provided a new understanding of the role
tides play in mixing the deep ocean
- developed the most accurate ever global
ocean tides' models
- provided the first global data set to test
ocean general circulation model performance
- demonstrated global positioning system
measurements in space could determine
spacecraft positions with unprecedented
accuracy, enabling rapid delivery of data.
Jason, a follow-on oceanography mission
launched in December 2001, is continuing
Topex/Poseidon's study of ocean circulation
affects on the Earth's climate. Jason
precisely maps the surface height, wind speed
and wave height of 95 percent of Earth's
ice-free oceans every 10 days. The data
provide invaluable input for short-term
weather forecasting, long-term climate
forecasting and prediction models.
Topex/Poseidon's stellar performance allowed
it to fly in tandem with Jason for nearly
three years, doubling data collection. This
allowed the study of smaller-scale ocean
phenomena like coastal tides, ocean eddies
and currents. It also improved understanding
of how low-frequency ocean waves transmit
signals of climate change.
Beyond Jason, the Ocean Surface Topography
Mission is in development for a scheduled
launch in 2008. It will continue providing
high-precision sea surface height data to the
oceanographic science community.
The joint effort had its genesis in 1979,
when NASA began developing the Topex mission,
while the Centre National d'Etudes Spatiales
was planning a similar one called Poseidon.
The agencies formed a single mission in 1983,
and it was launched August 10, 1992. JPL
manages the U.S. portion of
Topex/Poseidon/Jason for NASA's Science
Mission Directorate. Centre National d'Etudes
Spatiales manages the French portion of both
missions.

| POSEIDON |
 |
É ano novo a bordo do Poseidon. Alegres
passageiros confraternizam-se erguendo suas
taças para um brinde ao futuro. Mas o futuro
chega mais rápido do que eles imaginam; uma
onda de 150 pés acerta a lateral do
transatlântico e põe fim ao prazeroso
cruzeiro, virando o cruzeiro de cabeça pra
baixo, dando inÃcio a uma desesperada luta
pela sobrevivência. Um grupo de 6 pessoas
decide sair do lugar aonde estão para
tentarem buscar outra saÃda. Mas o destino
os reserva muitas surpresas.
Os passageiros precisam confiar uns nos
outros para encontrar a saÃda daquela
gigantesca armadilha marÃtima, enfrentendo
chamas, água e destroços de um mundo de
cabeça para baixo. E há um outro elemento
em cena; o espetacular Poseidon, em seus
incrÃveis 13 andares e com a altura
equivalente a 20 andares. Ele virou,
estremeceu e está prestes a implodir.
