Increased runoff and paleolake development, Thermal inertia of Mars: Sites of exobiological interest. Educator workshops using HiRISE and Mars Educational Program products will be held each year at or near the institution of a HiRISE team member. These images are being evaluated during the 6 months of aerobraking, to develop, test, and refine calibration and image‐processing techniques. Nevertheless, the ability to resolve the specific signatures related to individual geomorphic processes is crucial for understanding the geologic evolution of a planetary surface. If the spacecraft motion occurs mainly at particular frequencies, it may be possible to remove these artifacts by spatial filtering of the DEM as has been done for MOC data. Layering in Central Candor Chasma. The images are processed via automated procedures (HiProc) and checked by HiROC staff, students, and others to validate the results prior to PDS release. Another option is to slew the spacecraft or instrument or a scanning mirror to slow down the ground velocity of the instrument field of view; slewing the instrument is the strategy used by the Compact Reconnaissance Imaging Spectrometer for Mars, CRISM [Murchie et al., 2007].

Gully channels are the most suggestive of liquid water as the eroding agent [Malin and Edgett, 2000a]. Some layers appear to be only a few meters thick and are rhythmic, while other layers appear more resistant and massive in appearance.

Scene width is 3.2 km. In a full-resolution color image, Earth was 90 pixels across and the Moon was 24 pixels across from a distance of 142 million km. In this way we preserved meter‐scale resolution (3 pixels across a meter‐scale object) anywhere on Mars, provided high‐frequency spacecraft pointing jitter does not significantly smear the images. Can differences between short‐lived and long‐lived landforms provide clues about the Martian climate history with respect to water and temperature? Jitter can also have a third effect on HiRISE images that has no analog in our MOC experience: motions that occur during TDI will result in blurring in addition to geometric distortion.

[147] The future landing site of most immediate concern to MRO and HiRISE will be that for the 2007 Phoenix mission [Smith and the Phoenix Science Team, 2004].

The SFD of boulders, for example in a stratigraphic layer, may enable us to deduce whether or not the layer was emplaced as impact ejecta. However, the data volume per image is large so the number of such images will be limited. In fact, some models predict explosivities similar to plinian eruptions on Earth [e.g., Hort and Weitz, 2001; Hynek et al., 2003]. Off-Mars and Special Observations Values: Camera on board the Mars Reconnaissance Orbiter. Geomorphic evidence for shorelines has also been controversial, with several workers concluding that Noachian‐age features would no longer be recognizable. [152] The HiRISE team plans to cast a wide net to collect suggestions for the ∼10,000 high‐resolution images expected from the PSP.

Therefore, at equatorial latitudes we will try to have the emission angle of the 1st component of each stereo pair be small and looking either east or west, with the 2nd component being larger and looking west.

Other failed landers of potential interest are the 1971 Mars 2 and Mars 3 and 1974 Mars 6 landers from the former Soviet Union [Snyder and Moroz, 1992].

A general understanding of glacial and periglacial landforms and their specific morphological characteristics will aid in developing a broader understanding of the climate history of Mars and the history of water. Counter‐intuitively, tectonic features associated with the dichotomy are observed to be compressive on the southern side and tensile on the northern side. Dust devil triggering of slope streaks on Mars. If you do not receive an email within 10 minutes, your email address may not be registered, Testing the deltaic origin of fan deposits at Bradbury Crater, Mars.

High and low albedo features on Mars have fairly constant locations, but their extent and boundaries are highly variable from one year to the next [Geissler, 2005]. The general public is allowed to request sites for the HiRISE camera to capture (see HiWish).

Likewise data is transmitted from JPL to HiROC for data processing.

The visible camera of THEMIS provides images in five color band passes from 400 to 900 nm wavelength and up to 18 m/pixel scale, but these data contain a stray light component that has been difficult to calibrate [McConnochie et al., 2006]. Some of these hint at possible sources of water for future colonists. We cannot turn off nadir at will, as that may conflict with the desires of other MRO experiments or requirements. [61] The last two modes in Table 5 favor RED CCDs 2, 3, and 4, for use where high SNR is key but color is not important.

[20] The random noise is close to the desired values, ∼80 to 120 electrons RMS (root‐mean squared).
Comparatively little is known about local‐scale tectonics; these may hold the key to answering some outstanding questions. [35] A large set of internal calibration images were also acquired in December. However, both terrestrial experience and physical models indicate that Martian pyroclastics are likely to be very voluminous. High Resolution Imaging Science Experiment is a camera on board the Mars Reconnaissance Orbiter which has been orbiting and studying Mars since 2006.

[14] The first image below gives a wide view of the area. In particular there is interest in identifying meter‐scale hazards such as boulders and in characterizing periglacial landforms to aid in assessment of potential sites for meeting the Phoenix mission science objectives. Users will be able to download portions of a HiRISE image in a variety of popular image formats (tiff, jpeg, jpeg2000, gif, and PDS). However, evidence for fluids in ejecta emplacement, such as boulders transported by water or channels suggestive of dewatering of the ejecta flow, has not been confirmed in MOC images according to Williams and Edgett [2004].

Typically we will retire any suggestion or ROI that overlaps with an acquired image of high quality, but new suggestions may be entered at any time. Since HiROC is serving as a PDS data node, we can release image products as soon as possible, hopefully well before the formal delivery deadlines (6 months after acquisition for EDRs and end of mission for RDRs). value along the orbit track ranging from 0000 The loss of resolution in bin 1 images is minor because the PSF is broader than 1 pixel, but bin 2 and higher images could be more severely degraded. The dichotomy is demarcated by a topographic scarp that reflects a decrease in crustal thickness from the southern to the northern hemisphere.

[68] The objective of the HiRISE downlink process is to retrieve data from the MRO operations center at JPL, then produce and validate the products to be shared with users (the HiRISE science team, other MRO investigators, the Mars Exploration Program, the Mars science community, and the general public).

The bottom image shows the entire red‐filter image with 10 CCDs. We do not plan to use bin 16 since bin 8 is already highly compressed in data volume and is less likely to saturate.

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. [88] Subsurface ice abundances can also be investigated from viscous relaxation of topography [Squyres, 1989; Squyres and Carr, 1986]. Immediately after validation of the binned RDR products, the EDR and completed RDR products will be made available via HiWeb as well as PDS Web sites. This global picture serves well as a high‐level description of the state of Mars' volatiles, however in detail there are numerous questions to address regarding the condensation and sublimation processes. The images were acquired during a major solar flare and contain many cosmic‐ray “hits” or noise spikes.

HiRISE DEMs of multiple small craters on potentially ice‐rich terrains could be used to constrain the subsurface ice abundance, stratigraphy, and history, complementary to observations from the Shallow Radar (SHARAD) experiment on MRO [Seu et al., 2004, 2007].
