to a half-dozen space shuttle launches per year.
"The constrained shuttle flight rate requires that NASA give priority to [International Space Station] payloads, Hubble Space Telescope reboost, and microgravity payloads," said NASA spokesman David Steitz. "Consequently it's not possible to identify a definitive launch date for Triana."
The Triana team has been told to finish the spacecraft and prepare it for storage, Steitz said. NASA hopes to find a shuttle flight for the spacecraft "within the next several years," he said.
