  1. NASA launch staff and crew monitor cloud volume to ensure it doesn't present a safety hazard to the launch. Clouds can create two different types of risk to the launch. First, if the clouds are too numerous and too low, they can create a ceiling that prevents the U.S. Air Force from maintaining visual contact with the shuttle during its launch. A ceiling below 6,000 feet (1,829 meters) makes visibility with the shuttle impossible and will delay a launch. Second, the shuttle can cause lightening when passing through or near cumulus clouds. Clearly, the prospect of a lightning strike on the shuttle is not one NASA would risk.
