Hi-C to Investigate Activity in Solar Atmosphere

02.07.2012
NASA's Marshall Space Flight Center in Huntsville, Ala. is leading an international effort to develop and launch the High Resolution Coronal Imager, or Hi-C, on a sounding rocket from the White Sands Missile Range at White Sands, N.M. Hi-C is a next-generation suborbital space telescope designed to capture the highest-resolution images ever taken of the million-degree solar corona.

Key partners include the University of Alabama at Huntsville, Smithsonian Astrophysical Observatory, University of Central Lancashire in Lancashire, England, and the Lebedev Physical Institute of the Russian Academy of Sciences.


Hi-C will image the Sun at a 5x higher resolution (0.1 arcsec/pixel image) than any previously done. The mission will demonstrate the technology necessary to collect 150-kilometer-resolution images of the sun in the extreme ultraviolet spectrum. Using a resolution 5 times greater than any previous imager, Hi-C will observe the small-scale processes that exist everywhere in hot magnetized coronal plasma. Above image is 0.5 arcsec/pixel.

Understanding the sun's activity and its effects on Earth's environment is the critical scientific objective of Hi-C, which will provide unique, unprecedented views of the dynamic activity in the solar atmosphere.

The telescope is slated for launch in July 2012. It will fly aboard a Black Brant sounding rocket to be launched from the White Sands Missile Range in New Mexico.

The mission will demonstrate the technology necessary to collect 150-kilometer-resolution images of the sun in the extreme ultraviolet spectrum. Using a resolution 5 times greater than any previous imager, Hi-C will observe the small-scale processes that exist everywhere in hot magnetized coronal plasma. Additionally, the mission is designed to study the mechanisms for growth, diffusion and reconnection of magnetic fields of the corona, and to help understand the coupling of small-scale dynamic and eruptive processes to large scale dynamics.

A major scientific impact of Hi-C will be to place significant new constraints on theories of coronal heating and structuring, by establishing whether or not there is additional fine structure below the current level of resolution.

"This instrument could push the limits on theories of coronal heating, answering questions such as why the temperature of the sun's corona is millions of degrees higher than that of the surface," said Marshall heliophysicist, Dr. Jonathan Cirtain, who is Principle Investigator, on the Hi-C mission.

"Hinode has shown that current instrumentation used for coronal structure studies has insufficient resolution to separate individual features along the line-of-sight," Cirtain said. "Hi-C will accomplish this measurement, with margin".

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
