TUCSON, Ariz. -- The most powerful camera aboard a NASA spacecraft
orbiting Mars will soon be taking photo suggestions from the public.

Since arriving at Mars in 2006, the High Resolution Imaging Science
Experiment, or HiRISE, camera on NASA's Mars Reconnaissance Orbiter
has recorded nearly 13,000 observations of the Red Planet's terrain.
Each image covers dozens of square miles and reveal details as small
as a desk. Now, anyone can nominate sites for pictures.

"The HiRISE team is pleased to give the public this opportunity to
propose imaging targets and share the excitement of seeing your
favorite spot on Mars at people-scale resolution," said Alfred
McEwen, principal investigator for the camera and a researcher at the
University of Arizona.

The idea to take suggestions from the public follows through on the
original concept of the HiRISE instrument, when its planners
nicknamed it "the people's camera." The team anticipates that more
people will become interested in exploring the Red Planet while their
suggestions for imaging targets will increase the camera's already
bountiful science return. Despite the thousands of pictures already
taken, less than 1 percent of the Martian surface has been imaged.

Students, researchers and others can view Mars maps using a new online
tool to see where images have been taken, check which targets already
have been suggested and make new suggestions.

"The process is fairly simple," said Guy McArthur, systems programmer
on the HiRISE team at the University of Arizona. "With the tool, you
can place your rectangle on Mars where you'd like."

McArthur developed the online tool, called "HiWish," with Ross Beyer,
principal investigator and research scientist at NASA's Ames Research
Center in Moffett Field, Calif., and the SETI Institute in Mountain
View, Calif.

In addition to identifying the location on a map, anyone nominating a
target will be asked to give the observation a title, explain the
potential scientific benefit of photographing the site and put the
suggestion into one of the camera team's 18 science themes. The
themes include categories such as impact processes, seasonal
processes and volcanic processes.

The HiRISE science team will evaluate suggestions and put
high-priority ones into a queue. Thousands of pending targets from
scientists and the public will be imaged when the orbiter's track and
other conditions are right.

HiRISE is one of six instruments on the Mars Reconnaissance Orbiter.
Launched in August 2005, the orbiter reached Mars the following year
to begin a two-year primary science mission. The spacecraft has found
that Mars has had diverse wet environments at many locations for
differing durations in the planet's history, and Martian
climate-change cycles persist into the present era. Mars
Reconnaissance Orbiter is in an extended science phase and will
continue to take several thousand images a year. The mission has
returned more data about Mars than all other spacecraft combined.

"This opportunity opens up a new path to students and others to
participate in ongoing exploration of Mars." said the mission's
project scientist, Rich Zurek of NASA's Jet Propulsion Laboratory in
Pasadena, Calif.

The University of Arizona Lunar and Planetary Laboratory operates the
HiRISE camera, which was built by Ball Aerospace & Technologies Corp.
The Mars Reconnaissance Orbiter is managed by JPL for NASA's Science
Mission Directorate in Washington. Lockheed Martin Space Systems is
the prime contractor for the project and built the spacecraft.
