NASA Earth Observing Fleet including Landsat 8
This animation shows the orbits of NASA's current (as of May
2013) fleet of Earth remote sensing observatories. The satellites
include components of the A-Train (Terra, Aqua, Aura, CloudSat, CALIPSO), two satellites launched in 2011 (Aquarius, Suomi NPP), and nine others (ACRIMSAT, SORCE, GRACE, Jason 1 and 2, Landsat 7, Landsat 8, QuikSCAT, TRMM, and EO-1). These satellites measure tropical
rainfall, solar irradiance, clouds, sea surface height, ocean
salinity, and other aspects of the global environment. Together,
they provide a picture of the Earth as a system.
This is an update of entry 3725. It was created for display on the
NASA Center for Climate Simulation (NCCS) hyperwall, a 5 x 3 array
of high-definition displays with a total pixel resolution of 6840 x
2304. The orbits are based on orbital elements with epochs in April
of 2013. The animation spans twenty-nine hours, from 04:10 UT on
April 14, 2013 to 09:24 UT on Aril 15, 2013.
