On December 24, 1968, the Apollo 8 crew orbited the moon and discovered Earth. Astronauts James Lovell, command module pilot, William Anders, lunar module pilot, and Frank Borman, commander, were the first people to leave our planet to orbit another rocky body in space, and in this NASA video, we can travel with them to witness the moment they captured this iconic photo of home: Earthrise.
The 45th anniversary video uses data from NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft with audio recordings, data, and photographs from the orbiting lunar excursion module (LEM) to recreate this exhilarating and unanticipated moment of teamwork.

If you’ve seen physics teacher Dan Burns demonstrate how to use stretched spandex lycra to explain gravity and spacetime, then you’ll like this Fabric of the Cosmos how-to video from the 2012 SPS SOCK (Science Outreach Catalyst Kit). Meredith Woy and Melissa Hoffman build the model and then demonstrate orbits, tides, roche limits, and the creation of the solar system.
Physics Teacher SOS workshop leader Dan Burns demonstrates how he uses stretched spandex lycra, weights, marbles, and gravity in his high school classes to make this impressive space-time warping demo. Filmed from afar, this general relativity explainer was made for other educators, but my kids were riveted by these tangible representations that include how our planets orbit the sun, how the moon orbits the Earth, and the free return trajectory used in the Apollo Program.
Update: See how to set up this excellent demonstration in this Fabric of the Cosmos how-to video.
