On May 5, 2017, scientists will launch a sounding rocket 200 miles adult into a atmosphere, where in usually 5 minutes, it will take 1,500 images of a sun. The NASA-funded RAISE goal is designed to investigate split-second changes occurring nearby a sun’s active regions — areas of intense, formidable captivating activity that can give arise to solar flares, that eject appetite and solar element out into space.
Several missions invariably investigate a object — such as NASA’s Solar Dynamics Observatory, or SDO, and a Solar Terrestrial Relations Observatory, or STEREO — though certain areas of a object direct generally high-cadence observations in sequence to know a quick changes occurring there. That’s where RAISE — brief for Rapid Acquisition Imaging Spectrograph Experiment — comes in.
“Dynamic processes occur on all timescales,” pronounced Don Hassler, principal questioner for a RAISE goal during a Southwest Research Institute in Boulder, Colorado. “With RAISE, we’ll review out an picture any two-tenths of a second, so we can investigate really quick processes and changes on a sun. That’s around 5 to 10 times faster than allied instruments on other sounding rocket or satellite missions.”
RAISE images are used to emanate a information product called a spectrogram, that separates light from a object into all a opposite wavelength components. By looking during a power of light during any wavelength, scientists can consider how solar element and appetite moves around a sun, and how that transformation evolves into large solar eruptions.
“RAISE is pulling a boundary of high-cadence observations, and doing so is challenging,” Hassler said. “But that’s accurately what a NASA sounding rocket module is for.”
The moody of a sounding rocket is short-lived, and has a parabolic arena — a figure of a frown. Most sounding rocket flights final for 15 to 20 minutes, and usually 5 to 6 of those mins are spent creation observations from above a atmosphere, observations that can usually be finished in space. In RAISE’s case, a impassioned ultraviolet light a instruments observe can’t dig Earth’s atmosphere. After a flight, a cargo parachutes to a ground, where it can be recovered for use again.
This will be a RAISE mission’s third flight, and a scientists have invariably updated a technology. For a arriving flight, they have refurbished a detectors and updated a moody software, and a cargo carries a new diffraction grating, that reflects light and separates it into a apart wavelengths.
The launch window for RAISE opens during 2:25 p.m. EDT during a White Sands Missile Range nearby Las Cruces, New Mexico. The accurate timing of a launch depends on continue conditions, and concurrent timing with other space observatories such as NASA’s SDO and IRIS, as good as a corner Japan Aerospace Exploration Agency/NASA’s Hinode.
RAISE is upheld by NASA’s Sounding Rocket Program during NASA’s Wallops Flight Facility in Virginia. NASA’s Heliophysics Division manages a Sounding Rocket Program.
