The High Resolution Imaging Experiment (HiRISE) located on the Mars Reconnaissance Orbiter has already produced one of the largest data sets ever collected of Mars by sending back images of the surface, resolving objects as small as a desk. Earlier in the year, concerns were raised as image quality was declining and pixels were being lost. Recent testing has indicated that while some unexpected complications in the electronics will cause the images to be less than perfect, most of the problems can be ironed out, primarily by pre-warming certain components of the detector array prior to each image. Thus, scientists are confident that HiRISE will continue to send back high quality images for years to come.
