This animation shows the orbits of NASA's fleet of Earth observing spacecraft that are considered operational as of August 2021. The clouds used in this version are from a high resolution GEOS model run at 10 minute time steps interpolated down to the per-frame level.
Changes to this version include: removal of SORCE and the addition of Sentinel-6 Michael Freilich.
