STS-48
STS-48 was a NASA Space Shuttle mission launched in September 1991 aboard the Space Shuttle Discovery. Its main goals were to study Earth's atmosphere, particularly focusing on ozone layer observations, and to test new technology for space research. The crew conducted several scientific experiments, used onboard instruments to monitor atmospheric conditions, and deployed and retrieved satellites. The mission helped improve understanding of atmospheric chemistry and environmental monitoring from space, contributing to efforts to protect Earth's ozone layer and develop future space station technology.
