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".

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
