NASA Scientists Build First-Ever Wide-Field X-ray Imager

The unique collaboration involved heliophysics, astrophysics and planetary science divisions at NASA's Goddard Space Flight Centre in Greenbelt, Md., and resulted in the first successful demonstration of the Sheath Transport Observer for the Redistribution of Mass (STORM) instrument and a never-before-flown X-ray focusing technology called lobster-eye optics.
