The ATMOS Instrument on Board ATLAS 2The STS-56/ATLAS 2 mission was launched on April 8, 1993 from the Kennedy Space Center. During 9 days of operation, the ATMOS instrument made a total of 104 observations, 65 at sunrise in the north polar region around 65 degrees north, and 39 at sunset between 10 and 50 degrees south. The Arctic polar vortex, the airmass over the north pole where the processes leading to ozone depletion occur, was still partially intact even at this late date in the springtime; ATMOS took measurements both inside and out of this air. The shuttle landed on Runway 33 at KSC on April 17.
