Going Back-to-School with NASA Data

As students head back to school, teachers have a new tool that brings NASA satellite data down to their earthly classrooms. For over 50 years of observing Earth, NASA’s satellites have collected petabytes of global science data (that’s millions and millions of gigabytes) – with even more terabytes more coming in by the day. Since 2004, […]

PACE Celebrates National Ocean Month With Colorful Views of the Planet

What do you give to an ocean that has everything? This year, for National Ocean Month, NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite— is gifting us a unique look at our home planet. The visualizations created with data from the satellite, which launched on Feb. 8, are already enhancing the ways that we view […]
