unknown. Subsequent experiments with the Engineering Model (EM) at Ball Aerospace provided definitive evidence for the cause: contamination in the analog-to-digital converters (ADCs) which results in flipping bits to create the apparent noise or bad data in the images, combined with design flaws leading to delivery of poor analog waveforms to the ADCs. Further work showed that the degradation can be reversed by heating the ADCs. On October 3, 2007, HiRISE was turned toward Earth, and took a picture of it and the Moon. In the full-resolution color image, Earth was 90 pixels across and the Moon was 24 pixels across from a distance of 142 million km. On May 25, 2008, HiRISE imaged NASA's Mars Phoenix Lander parachuting down to the surface of Mars. It was the first time that one spacecraft imaged the final descent of another spacecraft onto a planetary body. By 2010, HiRISE had imaged only about one percent of Mars's surface and by 2016 the coverage was around 2.4%. It was designed to capture smaller areas at high resolution—other instruments scan much more area to find things like fresh impact craters. MRO's Context Camera (CTX) captured two fresh impact craters (>130 meter each) formed on Mars in late 2021, the largest discovered by MRO. These seismic events were also detected by Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight). The crater in Amazonis Planitia was discovered independently by both missions, while the crater in Tempe Terra was first observed by Insight and then searched for with CTX images. On April 1, 2010, NASA released the first images under the HiWish program in which the public suggested places for HiRISE to photograph. One of the eight locations was Aureum Chaos. The first image below gives a wide view of the area. The next two images are from the HiRISE image. The following three images are among the first images taken under the HiWish program. The first is a context image from CTX to show where the HiRISE is looking. Examples of HiRISE images The following group of images show some significant images taken by the instrument. Some of these hint at possible sources of water for future colonists. The following set of pictures show first a full image of a scene and then enlargements from parts of it. A program called HiView can be used to produce more detailed views. Some pictures are in
