释义
TOPEX/Poseidon

Space Exploration
  • A mission launched in August 1992 to map the surface topography of the Earth's oceans. It was a joint project involving NASA and the Centre National d'Etudes Spatiales (CNES), the French space agency, which launched the craft aboard an Ariane 4 rocket. Able to reveal minute differences in ocean height, the spacecraft monitored the effects of ocean currents on global climate change and investigated such phenomena as the El Niño climate changes. The data provided by TOPEX/Poseidon had also improved the understanding of the Earth's gravity field and produced the most accurate global maps of tides to date, as well as the first global views of seasonal changes in ocean currents. A malfunction ended the mission in January 2006.


Geology and Earth Sciences
  • A joint NASA and French Centre National d’Études Spatiales (CNES) space mission that was launched from French Guiana on 10 August 1992 into a polar orbit at a height of 1330 km. Its instruments measured sea level, tides, and large-scale ocean features, as well as changes in the heat stored in the oceans. The mission was planned to last three years, but it was not until October 2005 that a malfunction caused the satellite to cease transmitting data and it was turned off on 18 January 2006.
