Editing LEGRI (section)

The '''Low Energy Gamma-Ray Imager''' ('''LEGRI''') was a payload for the first mission of the Spanish [[MINISAT]] platform, and active from 1997 to 2002. The objective of LEGRI was to demonstrate the viability of [[Mercuric iodide|HgI<sub>2</sub>]] detectors for space [[astronomy]], providing imaging and spectroscopical capabilities in the 10-100 KeV range. 

LEGRI was successfully launched on April 21, 1997, on a Pegasus XL rocket. The instrument was activated on May 19, 1997. It was active until February 2002.<ref name="leg">[http://ipl.uv.es/?q=content/project/legri-low-energy-gamma-ray-imager LEGRI (Low Energy Gamma Ray Imager)]</ref>
