Stardust Space Capsule to Touch Down Sunday in Utah

If all goes according to plan, Stardust–a space capsule carrying a cargo of comet and interstellar dust particles–will scream into Earth’s atmosphere Sunday, deploy a series of parachutes, and drift down to the Utah desert.

Expected to land at 3:12 a.m. local time, the cargo may reveal answers to fundamental questions about comets, the origins of the solar system, and the building blocks of life.
