In March, NASA will launch five such rockets in approximately five minutes to study these high-altitude winds and their intimate connection to the complicated electrical current patterns that surround Earth. First noticed in the 1960s, the winds in this jet stream shouldn't be confused with the lower jet stream located around 30,000 feet, through which passenger jets fly and which is reported in weather forecasts. This rocket experiment is designed to gain a better understanding of the high-altitude winds and help scientists better model the electromagnetic regions of space that can damage man-made satellites and disrupt communications systems. The experiment will also help explain how the effects of atmospheric disturbances in one part of the globe can be transported to other parts of the globe in a mere day or two.
The five sounding rockets, known as the Anomalous Transport Rocket Experiment (ATREX), will launch from NASA's Wallops Flight Facility in Virginia releasing a chemical tracer into the air. The chemical — a substance called trimethyl aluminum — forms milky, white clouds that allow those on the ground to \"see\" the winds in space and track them with cameras. In addition, two of the rockets will have instrumented payloads to measure pressure and temperature in the atmosphere.", "items": [], "extra_data": {} }, { "id": 349855, "url": "https://svs.gsfc.nasa.gov/10922/#media_group_349855", "widget": "Video player", "title": "", "caption": "", "description": "Short narrated video about ATREX.

Little is known about this high altitude jet stream beyond the fact that its complex motion can spread space weather disturbances around the globe, which, in turn, can cause damage to satellites and disruption to communication systems. To observe the jet stream's wind patterns, NASA launched five 35-foot long sounding rockets packed with a chemical tracer over the Atlantic Ocean on March 27, 2012. Cameras on the ground tracked the movement of the glowing, milky-white clouds that developed in the early morning sky as the tracer deployed from the rockets and interacted with the jet stream.
