On the cliffs above San Francisco's Ocean Beach perches a landmark observatory—a giant camera obscura. Step inside with Robert Tacchetto and see how this centuries-old technology creates enchanting images of the outside world.
After its long journey to Saturn's largest moon, Titan, the Huygens probe is released from the Cassini spacecraft. The Huygens probe completes its descent to Titan, capturing hundreds of images on its way. Join Senior Scientist Paul Doherty as he gives us background on this incredible mission and sets the stage for the first close-up images of this mysterious moon.
Our team of middle school students from the Aim High program investigates new technologies that use our unique physical traits as tools for identification. Eye-D explores the possibilities of retinal scans.

Join us as NASA releases the first images from the Hubble Telescope's new camera, NICMOS (the Near Infrared Camera and Multi-Object Spectrometer). We'll discuss the significance and beauty of these pictures of our galaxy with the NICMOS' Lead Scientist, Keith Noll.
The Near Infrared Camera and Multi-Object Spectrometer (NICMOS) will be brought back to life with the installation of the new experimental NICMOS cryo-cooler. The cryo-cooler updates the technology from that of an icebox to a modern refrigerator. We also talk to Keith Noll, head if the Hubble Heritage Project, which is responsible for bringing us those stunning pictures from deep space.
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.
