Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) is a 2020s NASA Earth-observing satellite mission to observe global ocean color, biogeochemistry, and ecology, as well as the carbon cycle, aerosols and clouds. [3] PACE is intended to be used to identify the extent and duration of phytoplankton blooms and improve understanding of air quality. [4]
TOPEX/Poseidon was a joint satellite altimeter mission between NASA, the U.S. space agency; and CNES, the French space agency, to map ocean surface topography. Launched on August 10, 1992, it was the first major oceanographic research satellite. TOPEX/Poseidon helped revolutionize oceanography by providing data previously impossible to obtain.
Meanwhile, the Measurement of Air Pollution from Satellite (MAPS) instrument took data on the carbon monoxide content and distribution in the atmosphere since shortly after launch. During the initial activation of the X-SAR, controllers reported they were unable to fully power up the amplifier that provides power to the radar.
After less than one month in operation, Aquarius produced the first map showing the varying degrees of salinity across the ocean's surface produced by NASA. [8] The first salinity maps from space were provided by the European Space Agency satellite SMOS (Soil Moisture and Ocean Salinity) that was launched in November 2009. [9] Previous ...
The satellite will fly two radar antennas at either end of a 10 m (33 ft) mast, allowing it to measure the elevation of the surface across a 120 km (75 mi) wide swath. The new radar system is smaller than, but similar to, the one that flew on NASA's Shuttle Radar Topography Mission (SRTM), which made high-resolution measurements of Earth's land ...
The Blue Marble is a photograph of Earth taken on December 7, 1972, by either Ron Evans or Harrison Schmitt aboard the Apollo 17 spacecraft on its way to the Moon.Viewed from around 29,400 km (18,300 mi) from Earth's surface, [1] a cropped and rotated version has become one of the most reproduced images in history.
The decommissioning of the satellite took some days; the final decommissioning activities on the satellite ended 9 October 2019, with the satellite rendered fully inactive. [15] Because Jason-2 is orbiting at an altitude of over 1,300 km (810 mi), NASA estimates that it will remain in orbit for at least 500 to 1,000 years after decommissioning.
The crystallized magma forms a new crust of basalt known as MORB for mid-ocean ridge basalt, and gabbro below it in the lower oceanic crust. [16] Mid-ocean ridge basalt is a tholeiitic basalt and is low in incompatible elements. [17] [18] Hydrothermal vents fueled by magmatic and volcanic heat are a common feature at oceanic spreading centers.
