Origins: Hubble:  New Eyes for Hubble (Webcast)
Running Time:
00:31:20
The Advanced Camera for Surveys (ACS) was successfully installed. In preparation for the installation of the NICMOS Cooling System tomorrow, the astronauts also installed the Electronics Support Module. We also talk with Massimo Stiavelli, a scientist at the Space Telescope Science Institute about his involvement with the ACS and the future Wide Field Planetary Camera 3 (WFPC3) scheduled to be installed during the next servicing mission in 2004.

Origins: Antarctica:  Antarctica Fractals with Benoit Mandelbrot (Webcast)
Running Time:
0:46:48
In 1963 Benoit Mandelbrot introduced the fractal concept. Fractals are shapes or behaviors that have similar properties at all levels of magnification. Just as the sphere is a concept that unites raindrops, basketballs and Mars, so fractal is a concept that unites clouds, coastlines, plants and strange attractors. Dr. Mandelbrot dropped in for a visit during our 2001 series of webcasts about Antarctica. We took some time out from the freezing cold to interview him.
