When New England was hit by Tropical Storm Irene in 2011, there was not a satellite monitoring tropical storms that far north; the Tropical Rainfall Measuring Mission (TRMM) was operating in a band between the 35-degree latitudes. The Global... (View More) Precipitation Measurement (GPM) mission will change that. GPM will build upon TRMM's capacity by examining a larger swath of Earth with instruments that are more advanced and more sensitive. This video introduces the GPM satellite, its instruments and their capabilities. (View Less)

This video provides a glimpse into the snowfall research planned as part of the Global Precipitation Measurement (GPM) mission. GPM Deputy Project Scientist, Gail Skofronick-Jackson, reveals the capabilities of the satellite's new sensors, which,... (View More) through increased sensitivity, will help to overcome the challenges associated with measuring snowfall from space. (View Less)

In this brief video, NASA scientists discuss the Global Precipitation Measurement (GPM) mission and its role in studying and tracking Earth's freshwater resources. The GPM mission will advance our understanding of Earth's water and energy cycles,... (View More) improve the forecasting of extreme events that cause natural disasters, and extend current capabilities of using satellite precipitation information to directly benefit society.

Research physical scientist, Dr. Dalia Kirschbaum, is featured in this short (~3 min.) video. Dr. Kirschbaum explains how the integration of her initial interest in math and her subsequent interest in the science of natural disasters lead to her... (View More) career focus of landslide modeling. Now part of the NASA Global Precipitation Measurement (GPM) team, she communicates about the GPM mission and data to the public and to others who use it in their work and/or research. (View Less)

These short videos introduce learners to the electromagnetic spectrum though eight animations including an introduction to electromagnetic waves and one animation for each wavelength of the EM spectrum (Radio, Microwave, Infrared, Visible,... (View More) Ultraviolet, X-Rays and Gamma Rays). Each wavelength of the EM spectrum offers a construct to illustrate and teach about NASA sensors, missions, and science. Emphasis is placed on relevant science (e.g., lunar exploration) and hot science topics (e.g., climate change). Each video is computer animated and offers engaging illustrations to appeal to middle and high school age learners. The examples and narrative for each wavelength animation build on the learners’ prior knowledge then introduces examples from NASA missions. These examples explore the use of spectral analysis and visualizations that help scientists make discoveries about the world around us using EM waves. (View Less)

This 34-minute video is the result of a collaboration between the National Park Service and NASA. It tells the story of the Underground Railroad, the South/North escape routes used by freedom-seeking slaves during the 19th century. Slaves traveling... (View More) the Underground Railroad, usually on foot, depended on celestial navigation to find their way northward. They continually looked to the Big Dipper and the North Star for direction. The purpose of this video is to increase student awareness of the Underground Railroad and the role celestial navigation played in the Railroad's success. The video also highlights the importance of modern GIS technology in reconstructing historical topographies and finding the exact route of the Railroad. The video combines historical facts, such as the use of handmade quilts for communication, with topics including mathematics, remote-sensing technology, Earth system science, and astronomy.
