This packet holds tomato seeds that were flown on-board the Long Duration Exposure Facility (LDEF) in Canister 5 (layers C and D) under a thermal cover in the school bus- size cylindrical satellite's peripheral tray. These seeds are from among the 12.5 million that were in orbit for nearly 6 years - five more than was originally planned as a result of postponements and the loss of Space Shuttle Challenger.
