STS-78 was a space shuttle mission conducted by NASA, launched on June 20, 1996. The mission's primary objective was to conduct scientific research in microgravity aboard the Space Shuttle Columbia. It lasted for 17 days, during which astronauts performed various experiments in fields such as biology, materials science, and fluid mechanics. During STS-78, the crew included six astronauts who worked on over 30 experiments. The mission provided valuable data that contributed to our understanding of how different materials and biological systems behave in space. This information is essential for future long-duration space missions and the development of new technologies.
