A. Seeing The Earth In A New Light

Narrator: This is Science Today. For the first time, researchers will be able to study the Earth from a vantage point a million miles away in deep space. Francisco Valero, director of the Atmospheric Research Lab at the University of California's Scripps Institution of Oceanography, will lead this NASA-sponsored study called the Triana mission.

Valero: Normally, we put satellites in orbit very close to the Earth. This image is usually not complete. Satellites cannot see the whole Earth. So what Triana does, Triana goes far away enough. You can take a look at the whole sunlit side of the planet in one image.

Narrator: Once Triana is launched in December 2000, Valero says researchers and students alike will have a new way to study how the planet's climate works as an integrated system.

Valero: That is one of the main scientific objectives of Triana. We want to understand the radiative balance, the energy balance of the planet and relate that to the issues of global change and the issues of climate.

Narrator: For Science Today, I'm Larissa Branin.
