Rapid Acquisition Imaging Spectrograph Experiment or RAISE is a NASA funded series of sounding rocket missions to study the Sun in extreme ultraviolet.[1] RAISE is supported by NASA's Sounding Rocket Program at NASA's Wallops Flight Facility in Virginia. NASA's Heliophysics Division manages the Sounding Rocket Program.[1]
Several missions continuously study the Sun such as NASA's Solar Dynamics Observatory (SDO), and the Solar Terrestrial Relations Observatory (STEREO) but certain areas of the Sun demand especially high-cadence observations in order to understand the rapid changes occurring there. This is the purpose of RAISE.[1]
The third flight in the series was launched as RAISE at 14:24:58 EDT, on 5 May 2017. The payload was launched on a NASA Black Brant IX sounding rocket at the White Sands Missile Range in New Mexico and flew to an altitude of . The experimenter, Don Hassler with the Southwest Research Institute, reported that good data from the instruments observing the Sun was received during the flight. The payload was recovered.[1]
