Join the Exploratorium's Dr. Paul Doherty as he visits a "sculpture to observe the stars" in northern New Mexico, where the Sangre de Cristo Mountains meet the eastern plains. There artist Charles Ross is creating an art installation that is also a star observatory. This major earthwork has two main elements: the Star Tunnel, which allows you to walk through the entire history of the earth's changing alignment to our North Star, Polaris; and the Solar Pyramid, where one can visually experience an hour of the earth's rotation. 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. 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.
Noel and Paul spent several days at an active volcano, called Mt. Erebus. Join them for more stories about their trip and what the scientists are doing there. The first-ever live event inside the NASA clean room, where space hardware is being prepared for the Hubble Space Telescope. We'll get dressed in "bunny suits" to explore the room and show you the activities of engineers and scientists getting ready for the next Hubble servicing mission in November. A unique chance to watch the live progression of the making of a Hubble image! We'll select an image to follow over the course of the following webcasts, showing you the steps along the way as it goes from raw data to a full-color picture. And we'll talk with people who bring Hubble's fantastic images to the public. Part 2 of the previous program. Hubble's pictures have changed our understanding of the galaxy. Here we meet scientists who show us how their images have led to new discoveries, then check in on our own imaging project and track its progress. How much time does an astronomer need to get that great picture? We'll talk with scientists about how they determine their experiments, and learn what it takes to make their case for a few minutes of the telescope's time. What's so special about putting a telescope above the atmosphere? Find out by visiting Flight Operations and talking with scientists who've nurtured Hubble from the beginning. Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. This week’s “secret” ingredient: corks!
