Flown Heuer stopwatch carried on STS-29 by Mission Specialist Robert C. Springer, featuring dark blue hands on a white face with black Arabic numerals in five-second increments. The black back of the stopwatch is hand-etched "1006." In fine condition. Accompanied by a certificate of authenticity signed by Springer, in part: "This stop watch from my personal collection was flown on STS-29. Several of the experiments I operated required precise time constraints and I chose to use my personal stop watch to manage the critical events." Among the experiments conducted on STS-29 were a test on rats to determine whether the environmental effects of spaceflight inhibit bone healing, an experiment to determine the effects of spaceflight on fertilized chicken embryos, a test for a potential spacecraft cooling system, a protein crystal growth experiment, and a life sciences experiment designed to show the effects of microgravity on root development in plants. An interesting flown timepiece carried on a significant Shuttle mission.
