International Spacecraft Carrying NASA's Aquarius Instrument Ends Operations
An international Earth-observing mission launched in 2011 to study the salinity of the ocean surface ended June 8 when an essential part of the power and attitude control system for the SAC-D spacecraft, which carries NASA's Aquarius instrument, stopped operating. Read more
NASA's Ocean Salinity Pathfinder Celebrates its First Year in Orbit
It's been a busy first year in space for Aquarius, NASA's pioneering instrument to measure ocean surface salinity from orbit. Designed to advance our understanding of what changes in the saltiness of the ocean's top layer say about the water cycle and variations in climate, Aquarius took only two and a half months after its launch to start measuring global salinity patterns. Since then, it has also observed regional features such as the freshwater plume gushing from the Amazon River and localized changes in ocean saltiness following a tropical storm. Read more
Nasa has released the first global map of ocean surface salinity acquired by the Aquarius/SAC-D satellite, which was launched in June this year. Knowing the saltiness of seawater will improve scientists' understanding of some key climatic processes. Variations in salinity help drive ocean circulation and their measurement can also reveal how freshwater is moving around the planet. Read more
Aquarius Yields NASA's First Global Map of Ocean Salinity
NASA's new Aquarius instrument has produced its first global map of the salinity of the ocean surface, providing an early glimpse of the mission's anticipated discoveries. Aquarius, which is aboard the Aquarius/SAC-D (Satélite de Aplicaciones Científicas) observatory, is making NASA's first space observations of ocean surface salinity variations -- a key component of Earth's climate. Salinity changes are linked to the cycling of freshwater around the planet and influence ocean circulation. Read more
NASA's Aquarius instrument has successfully completed its commissioning phase and is now "tasting" the saltiness of Earth's ocean surface, making measurements from its perch in near-polar orbit. Read more
The Argentine satellite SAC-D/Aquarius launched today from Vandenberg military air base in California. The launch was initially programmed for yesterday, but it was postponed on Wednesday afternoon due to "minor inconsistencies" found in the "launch information system" at NASA, Delta II. Read more
A satellite that will map the saltiness of seawater has gone in orbit. Data from the Aquarius/SAC-D spacecraft will help scientists understand better the processes that drive ocean circulation and the movement of freshwater around the planet. A Delta rocket carried the satellite aloft, launching from California, US, at 0720 local time (1420 GMT). Read more
NASA'S "Age Of Aquarius" Dawns With Launch From California
NASA's 'Age of Aquarius' dawned Friday with the launch of an international satellite carrying the agency-built Aquarius instrument that will measure the saltiness of Earth's oceans to advance our understanding of the global water cycle and improve climate forecasts. The Aquarius/SAC-D observatory rocketed into space from Vandenberg Air Force Base in California atop a United Launch Alliance Delta II rocket at 7:20:13 a.m. PDT. Less than 57 minutes later, the observatory separated from the rocket's second stage and began activation procedures, establishing communications with ground controllers and unfurling its solar arrays.
