From east coast of Virginia on July 4 were launched two small NASA rockets, directed on an [ad name=”Google Adsense-3 11″] orbit for research of electric whirlwinds in Earth upper atmosphere. Two small NASA rockets started within 15 seconds from the NASA spaceport on the State of Virginia. The mission is to investigate global electric whirlwinds in Earth ionosphere with help of the devices installed on Black Brant V and Terrier-Improved Orion rockets probes. By the words of representatives of NASA they prepared Black Brant V and Terrier-Improved Orion start for show of fireworks in honor of the Independence Day. Start of NASA rockets On the Fourth of July were part of mission of Daytime Dynamo, the joint project with Japanese agency of space researches to study movement of electric whirlwinds in Earth ionosphere at distance between 30 and 600 miles (48 and 965 kilometers) over a surface. People on Earth depend on this current in an ionosphere, called by a dynamo current, every day. Radio signals are reflected from an ionosphere during translations, and satellite communication and navigation signals have to pass through an ionosphere to reach Earth. When the ionosphere is excited, these signals can be distorted. On the big Black Brant V rocket was installed the equipment for measurement of the neutral and loaded particles in Earth ionosphere. The rocket of less Terrier-Improved Orion bears the canister with lithium gas, having let out which will create a chemical trace. The trace will allow scientists to trace on Earth of electric whirlwinds. Two NASA rockets will remain at the height about 100 miles (160 kilometers) and quickly enough to rotate round Earth. Start of rockets took place after several days of a delay in connection with adverse weather conditions.
