NASA's Stardust sample return capsule brought home the world's first particles from a comet to join the collection of flight elite in the Smithsonian's National Air and Space Museum in Washington D.C. The capsule will go on public display in the museum's Milestones of Flight Gallery on October 1, the 50th anniversary of NASA.

Stardust, comprising a spacecraft and capsule, completed a seven-year, 3-billion-mile journey in 2006. A tennis racket-like, aerogel-lined collector was extended to capture particles as the spacecraft flew within 150 miles of comet Wild 2 in January 2004. Carrying the collected particles, the capsule returned to Earth January 15, 2006, landing in Utah. Two days later, it was transported to a curatorial facility at NASA's Johnson Space Center in Houston.

"Very few people get to build something, launch it into space, see it be successful and then get it back in their hands," said Karen McNamara, Johnson recovery lead for the Stardust mission. "To be able to share this with the public is phenomenal."

The capsule joins the Wright brothers' 1903 Flyer, Charles Lindbergh's Spirit of St. Louis and the Apollo 11 command module Columbia that carried the first men to walk on the moon. Hardware provided to the Smithsonian includes actual flight components. Elements relevant to the science goals of the mission remain with NASA.

After successfully completing its mission, Stardust will use its flight-proven hardware to perform a new, previously unplanned investigation. The mission, called Stardust-NExT, will revisit comet 9P/Tempel 1. This investigation will provide the first look at the changes to a comet nucleus produced after a close approach to the sun. It also will mark the first time a comet ever has been revisited.

"Usually, when a piece of your spacecraft goes into the Smithsonian that means the mission's over," said Stardust-NExT project manager Rick Grammier, of NASA's Jet Propulsion Laboratory in Pasadena, California "But the Stardust spacecraft is still doing the job for NASA and in February 2011, it will fly within 120 miles of the comet."

Stardust is a low-cost, Discovery Program mission for NASA's Science Mission Directorate. The Jet Propulsion Laboratory manages the project. Joseph Veverka of Cornell University in Ithaca, New York, is the mission's principal investigator. Lockheed Martin Space Systems of Denver, Colorado manages mission operations.
