36.219 US Black Brant IX was launched from White Sands Missile Range, NM on August 23, 2010.The purpose of this mission is to observe and analyze dynamics and heating of the solar chromosphere and corona. The Rapid Acquisition Imaging Spectrograph Experiment (RAISE) sounding rocket payload is an extremely high speed scanning-slit imaging spectrograph designed to observe and analyze dynamics and heating of the solar chromosphere and corona on time scales as short as 100 ms, with TRACE-like spatial resolution and a velocity sensitivity of 1-2 km/s. RAISE will address three general topics that are accessible only with our instrument's unique capabilities: 1) Small-scale multithermal dynamics in active-region loops; 2) the strength, spectrum, and location of high frequency waves in the solar atmosphere; and 3) the nature of transient brightenings in the chromospheric network. The Principal Investigator is Dr. Don Hassler/Soutwest Research Institute.
