NASA is set to launch on Saturday a sounding rocket which will release blue-green and red artificial clouds. "Clear skies are required at one of the ground stations to view blue-green and red artificial clouds that will be produced as part of the test. These artificial clouds may be seen from New York to North Carolina," NASA said.
The rocket will eject 10 canisters about the size of a soft drink can between 10 to 20 km from the rocket's main payload, and these containers will release the vapour between 4 and 5.5 minutes after launch.The development of the multi-canister or ampule ejection system will allow scientists to gather information over a much larger area than previously allowed when deploying the vapour just from the main payload.
"The vapour tracers are formed through the interaction of barium, strontium and cupric-oxide. The tracers will be released at altitudes 96 to 124 miles high and pose absolutely no hazard to residents along the mid-Atlantic coast," NASA said.
