#TBT: Space Shuttle Atlantis Returns to Work -- Nov. 3, 1994
This week in 1994, space shuttle Atlantis returned to work for its first flight since July 1992 after being refurbished. STS-66 advanced comprehensive efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere and how these factors affect global ozone levels.
NASA missions and researchers address some of the critical challenges facing our planet today and in the future -- climate change, sea level rise, freshwater resources and extreme weather events.
