Associated space launch
MSX (Midcourse Space Experiment) demonstrated different multispectral imaging technologies to identify and track ballistic missiles during flight by observing rocket launches and orbital debris. Additionally it measured the composition and dynamics of the Earth's atmosphere by observing ozone, chloroflourocarbons, carbon dioxide and methane.
MSX was lifted into orbit during the mission ‘Delta II | MSX’, on board a Delta II space rocket.
The launch took place on April 24, 1996, 12:27 p.m. from Space Launch Complex 2W.
