Origins: Hubble:  Hubble Space Telescope Servicing Mission 4 (Webcast)
Running Time:
00:32:23
On May 11, 2009, the space shuttle Atlantis was launched from the Kennedy Space Center and docked with the Hubble Space Telescope 360 miles above the earth. During Servicing Mission 4 (SM4), astronauts installed new, cutting-edge scientific instruments and replaced gyroscopes, batteries, and other equipment. After a difficult but very successful upgrade of the telescope, the astronauts released Hubble on May 19. The Exploratorium Webcast team will bring you two live Webcasts (May 20 & May 23) about this arduous mission and the future of the telescope.

Ice Stories:  Clockwise (Clip)
Running Time:

Why do the hands on clocks go "clockwise?" Seems like a circular definition, but if you looked closely at sundials in the northern hemisphere, you'd notice that the shadow of the sun moves around the sundial in a "clockwise" direction. This was adopted by clock-makers and became the standard we know today. In the southern hemisphere, the sun's shadow moves around the dial in the opposite direction, so if clocks had been invented there, our watches would move the other way.

Solar Eclipse:  Live from China (Webcast)
Running Time:
01:13:00
On August 1, 2008, a total solar eclipse occurred as the new moon moved directly between the sun and the earth. The moon's umbral shadow fell on parts of Canada, Greenland, the Arctic Ocean, Russia, Mongolia, and China. The Exploratorium's eclipse expedition team (our fifth!) Webcast the eclipse live from the remote Xinjiang Uygur Autonomous Region in northwestern China near the Mongolian border.
