2008 challenge acquired suggestions have been
posted and are available to registered participants. Remind
them
Remember: to check back often as challenge suggestions continue to be
acquired.

This challenge is brought
to you by MRO’s High
Resolution Imaging Science Experiment (HiRISE) camera team in
collaboration with NASA Quest. The HiRISE camera, now orbiting
Mars onboard the Mars Reconnaissance Orbiter, is helping NASA
to search for signs of past and present water on Mars. Understanding
the history of water on Mars helps scientists understand if there
is now or ever has been life on Mars.
Scientists have argued for
water on Mars since the first Viking images of Mars were returned
nearly 30 years ago. Since
then, Mars Global Surveyor and Mars Odyssey have collected more
images; now the High Resolution Imaging Science Experiment (HiRISE)
is using a camera attached to a very powerful telescope to look
down on the surface of Mars. |
HiRISE is taking photos of Mars that are higher
in resolution (~30cm/pixel), showing more detail, than any previous
images. Objects as small
as a meter across, approximately the size of a teacher’s desk,
can be seen in the HiRISE images. This allows HiRISE to find small
features like interior channels, streambed features, and layering. Since
the HiRISE camera is “zoomed in” to look at very small regions
of Mars, it will only be able to image about 2% of the surface of the
planet. Thus each image has to count!
You are challenged to help choose some regions
of Mars for HiRISE to image that probably contained water at the surface
in the past. The
HiRISE team will pick several suggestions and image them with the camera
in the coming months. Your team will represent the first people
on Earth to see the resulting image and will have the chance to search
for signs of water in the image.
You can choose areas within a valley system or
outflow channel (like the source region or other interesting spot on
the floor or walls) or obtain a close-up of gullies imaged from past
missions. You can
also choose to re-image an interesting site already seen in a HiRISE
image to look for any changes that may indicate present geologic activity.
To increase your chances of getting your image picked sooner rather
than later, here are a few tips:
- Don’t pick a dusty area. A
large fraction of the planet is covered in dust, and a lot of dust means
that the surface features are hidden.
- Northern Summer begins on June 25, 2008, so we will be focusing on
targets
that are north of latitude 30 degrees South.
- Have a well thought out hypothesis for selecting this target location.
Very few
images can be taken at any given time, and the camera is restricted by
its orbital path and the time of year. In addition, HiRISE is one of
several instruments on board the Mars Reconnaissance Orbiter that also
need to collect data and are allocated part of the data downlink volume.
Image
captions and analysis reports will form the basis for a weekly captioned
student image release on the HiRISE image release website http://hirise.lpl.arizona.edu. Even
if your target is not selected this round, keep checking the website!
You’ll also be able to see what
other school groups have suggested and help in the analysis of those
sites! We want all participating classes to analyze their favorite returned
HiRISE image, whether or not they actually suggested it, and submit a
report on their analysis.
See the calendar below for
planning purposes. Prepare for the Challenge with some background
references to learn about the Mars Reconnaissance Orbiter and Martian
terrain options. Grade-specific
Teacher's Guides and Student Activity Books, tutorials, and other helpful
information are available in .pdf format from the HiRISE
Learning and Activity Center. To browse the released HiRISE
images and for additional information about HiRISE, visit the main
HiRISE website at: http://hirise.lpl.arizona.edu.

Registration
Continues!
Although the Spring 2008 challenge submission deadlines have passed,
that educators and students can still register and and submit image
suggestions.
Please note: After you have registered for the HiRISE Image Targeting
Challenge you will be receive an email giving you information on
how to access to the active website by registering
to HiWeb. HiWeb is the place where you will view images and submit
your entries.
HiWeb
is HiRISE's interactive image suggestion facility and is the same
tool that HiRISE team members use to submit, view and browse all
HiRISE image suggestions. |
Now!
| Begin preparation, understanding:
- What the Mars HiRISE (High Resolution Imaging Science Experiment)
is.
- How is High Resolution photography going to affect what we
are able to see?
- What makes one site better than another in determining where
water/life may have existed in the past?
- Begin to form your
opinion of where you would like to look.
- Explore the Clickworkers to learn to recognize geologic features
images and help build image feature databases for the
HiRISE team.
To help you get started, we've created a page
to step you through the process. It links to a point-by-point tutorial on the use of
HiWeb. Only Registered Participants have access to the HiWeb (Grade-specific Teacher
Guides and Activity Books are available online in .pdf format.)

Thursday, March 6
Web Chat
10:00 a.m. PST
|
Join Dr. Virginia Gulick and ask
your questions about the process of finding and submitting your target
for imaging by HiRISE.
The chat room is now open, so if your schedule will not allow
you to join us on Tuesday, please submit your questions early,
and we will answer as many as possible live. The you can return
and read the archive to find the answers to your question and any
others handled during this hour long chat. |
First Cycle Deadline:
March 9
|
When you have formed an hypothesis
and are ready to request and support your selection of that site,
enter your information at the HiWeb site. Images for this cycle
should be available April 19. As images are available, they will
be open to all registered participants
only. |
March 30 - April 12 |
Images will be acquired for First
Cycle. |
April 30 |
Submit your analysis report and
caption. |
Second Cycle Deadline:
March 23 |
When you have formed an hypothesis
and are ready to request and support your selection of that site,
enter your information at the HiWeb site. Images for this cycle should
be available April 19. As images are available, they will be open
to all registered participants
only. |
April 13 - April 26 |
Images will be acquired for Second
Cycle |
Final reports Due
for Cycle 2 images
May 21 |
As image of student-suggested
sites are downloaded, it is time to participate in the fun of analyzing
these. You can pick any HiRISE image
to analyze, submit a brief report on
it and help write image captions.
This webcast is designed
to help you with this part of the challenge (review, analysis,
and captioning images). If you cannot make the hour of the webcast,
place your questions in the chat room early. We will archive the
webcast as soon as possible after the webcast.
As students
review the images, our NASA experts will be preparing their
comments.
For easier viewing, the slides for this webcast will
be available for download.

Does High Resolution Imagery confirm or refute your hypothesis?
Anything else?

your Challenge Written Report.
Student images are open
only to those who register until
the images have been officially released on the main
HiRISE site.... |
