The HiRISE camera, one of
the instruments on the Mars Reconnaissance Orbiter, has been sending
back high-resolution images of Mars since late 2006. On this site, you
can help us identify landforms in these images. You can also call
attention to interesting features in images taken from a previous
orbiter. These might be considered as places to aim HiRISE in the
The HiRISE task that you can get started on right now is a landform
search. We could use volunteers to sift through images looking for sand
dunes, run through images looking for channels, pore through images
looking for gullies, and more. (Unlike the
task we did as a
, the goal for now is just to locate the features, not measure them.
We're still thinking about the best way to reduce each of these new
landform types to a few numbers.)
Help direct scientists to the features that interest them — catalog HiRISE images.
HiRISE images are huge!
single image, zoomed in all the way, is more than ten computer screens
wide and high. It would take a person a long time to systematically
examine those 100 screens completely at full detail, even ignoring the
significant time it would take to download a full image. Although it's
possible for a scientist or other person to zoom in to areas that look
promising (you can do that using the HiRISE online image viewer
if you're curious), that will tend to overlook small features that
appear in unexpected places, and those would be interesting to know
about. With enough volunteers, a systematic inspection of the images at
all scales may be possible.
Help find new places on Mars for HiRISE to take pictures — search MOC images for landforms of interest.
Mars Global Surveyor operated for over 9 years, and its camera, MOC
returned almost a quarter of a million images. You can look through
these to identify areas that contain landforms that are of particular
interest to scientists on the HiRISE team. This may help guide the
selection of future locations for HiRISE to image. Also, if while
looking for those landforms, you happen see an area that you personally
would like to see imaged, by HiRISE, you can suggest that too. (We will
collect these requests and decide later how to filter them, since we
expect more requests than HiRISE can handle.)
Note: We will show you whole MOC images, and while they're not as large as HiRISE images, they're very large.
