The 65 kg (143 lb), US$40 million instrument was built under the direction of the [[University of Arizona]]'s [[Lunar and Planetary Laboratory]] by [[Ball Aerospace & Technologies Corp.]] It consists of a 0.5{{nbsp}}m (19.7 in) aperture [[reflecting telescope]], the largest so far of any [[deep space exploration|deep space]] mission, which allows it to take pictures of Mars with resolutions of 0.3{{nbsp}}m/pixel (1{{nbsp}}ft/pixel), resolving objects below a meter across.
HiRISE has imaged [[Mars Exploration Rover|Mars exploration rovers]] on the surface, including the [[Opportunity rover|''Opportunity'' rover]] and the ongoing [[Curiosity rover|''Curiosity'' mission]].<ref name=voa>{{cite web|url=https://www.voanews.com/a/mars-orbiter-photographs-old-nasa-landers-139039139/173778.html|title=Mars Orbiter Photographs Old NASA Lander|work=[[VOA]]|access-date=20 November 2018|date=February 8, 2012}}</ref>
==History== [[Image:MRO-First Image-crop.jpg|thumb|left|Crop of one of the first images of Mars from the HiRISE camera]] In the late 1980s, {{MoMP|16975|Alan Delamere}} of [[Ball Aerospace & Technologies]] began planning the kind of high-resolution imaging needed to support sample return and surface exploration of Mars. In early 2001 he teamed up with Alfred McEwen of the University of Arizona to propose such a camera for the Mars Reconnaissance Orbiter (MRO), and NASA formally accepted it November 9, 2001.
Ball Aerospace was given the responsibility to build the camera and they delivered HiRISE to NASA on December 6, 2004 for integration with the rest of the spacecraft. It was prepared for launch on board the MRO on August 12, 2005, to the cheers of the HiRISE team who were present.
[[Image:Hirise at mars.jpg|thumb|right|Artist's rendition of HiRISE at Mars]]
During the cruise phase of MRO, HiRISE took multiple test shots including several of the [[Moon]] and the [[Jewel Box (star cluster)|Jewel Box]] cluster. These images helped to calibrate the camera and prepare it for taking pictures of Mars.
On March 10, 2006, MRO achieved Martian orbit and primed HiRISE to acquire some initial images of Mars.<ref name="Ref_a">{{cite web|url=http://mars.jpl.nasa.gov/mro/mission/orbiter_update.html |title=Mars Reconnaissance Orbiter Successfully Enters Orbit Around Mars! |work= NASA MRO website| access-date=2006-06-08 |archive-url = https://web.archive.org/web/20060603061811/http://mars.jpl.nasa.gov/mro/mission/orbiter_update.html <!-- Bot retrieved archive --> |archive-date = 2006-06-03}}</ref> The instrument had two opportunities to take pictures of Mars (the first was on March 24, 2006) before MRO entered aerobraking, during which time the camera was turned off for six months.<ref name="Nasa2006">{{cite press release | publisher=NASA | date=2006-03-24 | title=UA Team Cheers Launch of Mars Reconnaissance Orbiter, HiRISE | url=http://mars.jpl.nasa.gov/mro/newsroom/pressreleases/20060324a.html | access-date=2006-06-08}}</ref> It was turned on successfully on September 27, and took its first high-resolution pictures of Mars on September 29.

Further work showed that the degradation can be reversed{{clarify|date=January 2021}} by heating the ADCs.{{cn|date=January 2021}}
On October 3, 2007, HiRISE was turned toward [[Earth]], and took a picture of it and the [[Moon]].

These seismic events were also detected by [[InSight|Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight)]].

==Purpose== [[Image:Mars Reconnaissance Orbiter HiRISE comparison.jpg|thumb|Comparison of resolution of MRO HiRISE camera with predecessor, the [[Mars Orbiter Camera|MOC]] aboard [[Mars Global Surveyor|MGS]]]]

The general public is allowed to request sites for the HiRISE camera to capture (see [[HiWish program|HiWish]]). For this reason, and due to the unprecedented access of pictures to the general public, shortly after they have been received and processed, the camera has been termed "The People's Camera".<ref name="Ref_i">{{cite web |url=http://hirise.lpl.arizona.edu |title=HiRISE |publisher=[[Lunar and Planetary Laboratory]], [[University of Arizona]] |access-date=19 March 2006 }}</ref> The pictures can be viewed online, downloaded, or with the free [[HiView]] software.
==Design== [[Image:The Earth and the Moon photographed from Mars orbit.jpg|thumb|Photograph of Earth and Moon roughly to scale, taken from Mars orbit by HiRISE]] HiRISE was designed to be a high resolution camera from the beginning. It consists of a large mirror, as well as a large [[Charge-coupled device|CCD]] camera. Because of this, it achieves a [[Angular resolution|resolution]] of 1 [[radian|microradian]], or 0.3 meter at a height of 300 km. (For comparison purposes, satellite images on [[Google Mars]] are available to 1 meter.<ref name="Ref_j">"[http://earth.google.com/faq.html#4 Google Earth FAQ]" ''Google Earth Website''.</ref>) It can image in three color bands, 400–600 nm ([[blue]]–[[green]] or B–G), 550–850 nm ([[red]]) and 800–1,000 nm ([[near infrared]] or NIR).<ref name="Ref_k">{{cite web |url=http://marsoweb.nas.nasa.gov/HiRISE/instrument.html#components |title=MRO HiRISE Camera Specifications |work=HiRISE website |access-date=2 January 2006 }}</ref>
HiRISE incorporates a 0.5-meter primary mirror, the largest optical telescope ever sent beyond Earth's orbit. The mass of the instrument is 64.2 kg.<ref name="Ref_l">[http://cat.inist.fr/?aModele=afficheN&cpsidt=20649610 Mission to Mars: the HiRISE camera on-board MRO], ''Focal plane arrays for space telescopes III,'' 27–28 August 2007, San Diego, California, USA</ref>
Red color images are at 20,048 [[pixel]]s wide (6 km in a 300 km orbit), and blue-green and NIR are at 4,048 pixels wide (1.2 km). These are gathered by 14 CCD sensors, {{nowrap|2048 × 128 pixels}}. HiRISE's onboard computer reads out these lines in time with the orbiter's [[ground speed]], meaning the images are potentially unlimited in height. Practically this is limited by the onboard computer's {{nowrap|28 [[Gigabit|Gbit]]}} ({{nowrap|3.5 GB}}) memory capacity. The nominal maximum size of red images (compressed to 8 bits per pixel) is about 20,000 × 126,000 pixels, or 2520 [[megapixel]]s and 4,000 × 126,000 pixels (504 megapixels) for the narrower images of the B–G and NIR bands. A single uncompressed image uses up to 28{{nbsp}}Gbit. However, these images are transmitted compressed, with a typical maximum size of 11.2 gigabits. These images are released to the general public on the HiRISE website as [[JPEG 2000]].<ref name="Ref_m">{{cite web |url=http://marsoweb.nas.nasa.gov/HiRISE/papers/6th_int_mars_conf/Delamere_HiRISE_InstDev.pdf |title=HiRISE: Instrument Development |work=NASA Ames Research Center website |access-date=7 February 2006 }}</ref><ref name="Ref_n">{{cite web |url=http://www.nasm.si.edu/research/ceps/cepsicons/highlights/fact_sheet_front.pdf |title=Fact Sheet: HiRISE |work=National Air and Space Museum |access-date=18 February 2006 |archive-url=https://web.archive.org/web/20130621134946/http://airandspace.si.edu/research/ceps/cepsicons/highlights/fact_sheet_front.pdf |archive-date=21 June 2013 }}</ref>
To facilitate the mapping of potential landing sites, HiRISE can produce stereo pairs of images from which the topography can be measured to an accuracy of 0.25 meter.

The target code refers to the latitudinal position of the center of the planned observation relative to the start of orbit. The start of orbit is located at the equator on the descending side (night side) of the orbit. A target code of 0000 refers to the start of orbit. The target code increases in value along the orbit track ranging from 0000 to 3595. This convention allows the file name ordering to be time sequential. The first three digits refers to the number of whole degrees from the start of orbit, the fourth digit refers to the fractional degrees rounded to the nearest 0.5 degrees. Values greater than 3595 identify observations as off-Mars or special observations.
Examples of target code: * 0000 – planned observation at the equator on descending side of orbit. * 0900 – planned observation at the south pole. * 1800 – planned observation at the equator on the ascending side (day side) of the orbit. * 2700 – planned observation at the north pole.
Off-Mars and Special Observations Values: * 4000 – Star Observation * 4001 – Phobos Observation * 4002 – Deimos Observation * 4003 – Special Calibration Observation
