NASA efficiently launched the Auroral Zone Upwelling Rocket Experiment or AZURE mission on April 5 from the Andøya House Middle in Norway.
Two Black Brant XI-A sounding rockets had been launched at 6:14 and 6:16 p.m. EDT on April 5 carrying scientific devices for learning the power alternate inside an aurora.
The AZURE mission is designed to make measurements of the atmospheric density and temperature with devices on the rockets and deploying seen gasoline tracers, trimethyl aluminum (TMA) and a barium/strontium combination, which ionizes when uncovered to daylight. The vapors had been launched over the Norwegian Sea at 71 by 150 miles altitude.
These mixtures, utilizing substances much like these present in fireworks, created colourful clouds that permit researchers to trace the movement of impartial and charged particles with the auroral wind. By monitoring the motion of those colourful clouds by way of ground-based images and triangulating their moment-by-moment place in three dimensions, AZURE will present useful knowledge on the vertical and horizontal movement of particles in two key areas of the ionosphere over a variety of various altitudes.
Many individuals consider the Earth’s ambiance “ends” some 20-30 miles above the bottom. Nonetheless, the air we breathe doesn’t abruptly finish at some predefined level — as an alternative, it step by step thins. At 150 to 200 miles above Earth, the “air” is extraordinarily skinny and these vapor clouds disperse quickly and observe the winds which may be transferring at a number of hundred miles per hour.
AZURE is one in all 9 missions being carried out as a part of the Grand Problem Initiative (GCI) – Cusp, a collection of worldwide sounding rocket missions deliberate for launch in 2018 – 2020.
NASA and U.S. scientists are becoming a member of these from Norway, Japan, Canada and different international locations to analyze the physics of heating and charged particle precipitation on this area referred to as the geomagnetic cusp — one of many few locations on Earth with quick access to the electrically charged photo voltaic wind that pervades the photo voltaic system.
NASA beforehand carried out two missions in December 2018 and two in January 2019 as a part of the Initiative. The ultimate two NASA missions — the Cusp Heating Investigation and the Cusp Area Experiment — are scheduled for November 2019.

AZURE is supported by NASA’s Sounding Rocket Program on the company’s Wallops Flight Facility in Virginia. NASA’s Heliophysics Division manages the sounding rocket program.
