The High Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter (MRO) acquired 8 terapixels of data in 9137 images of Mars between October 2006 and December 2008, covering ~0.55% of the surface. Images are typically 5–6 k

We present in detail the laboratory apparatus and techniques that were used to complete a full radiometric calibration of two space-based lightning detectors developed at NASA Marshall Space Flight Center (MSFC). A discussion of the methods applied t

Following its launch in August, 2005 and a year of interplanetary cruise and aero-braking, the successful Mars Reconnaissance Orbiter (MRO) mission is currently orbiting Mars and down-linking imagery from the High Resolution Imaging Science Experimen

The Lightning Imaging Sensor (LIS) wide field-of-view solid-state camera can measure the global distribution of lightning from LEO, through the use of a narrowband interference filter to detect the neutral O band at 777.4 nm. Prelaunch testing and ca

We examine the role of processing errors on diffraction efficiency of binary optical elements and the validity of the Fourier model to predict diffraction efficiency. We show that mask alignment error can significantly degrade efficiency. Models base

For many applications, for example, in ground-based astronomy, detector systems using small arrays or small numbers of discrete IR. detectors are very useful. In particular, systems using indium antimonide (InSb) detectors are approaching background-
