Quest Spring 2008 Challenge Written Report

Name of teacher/student or class group:
- What HiRISE image did you choose to analyze?
- Describe the area that has been imaged
by HiRISE. You can do this by using some of the lower resolution
Mars images* for overviews. (For example, is it part of a valley,
canyon system, located in a crater, or near a volcano? What is the
name of the area or feature? Is it located in the South Polar Region? Is
it equatorial?) What features in the images provide clues to the
type of geologic setting? Why might this be a good general area to
look for evidence of water? What additional information can
you find about the area on the web or in your textbooks.
* Hint: There are many ways to do this. Easiest: Look at the lower
resolution zoomable map (located on the website below the HiRISE Quest
student challenge images) or the Context image map (located below the
selected HiRISE image. More challenging: Log in to our image suggestion
website and type in the latitude and longitude on the front main page.
Or you can click on an area on the colorful Mars map to bring up a zoomable
Mars map. Click the “gazetteer” and “grid” buttons
at the bottom of this map to see the lat/lon and place names added. Most
Challenging: You can also go to the login/image suggestion website and
type in the HiRISE Image ID number to bring up the area of interest.
- When you look at the whole HiRISE image on the Quest website
(http://marsoweb.nas.nasa.gov/hirise/quest),
zoomed all the way out, what do you see? Does it look like
anything you’ve seen on Earth?
- Use the
pan/zoom feature on the HiRISE Quest image website to zoom in and
view the HiRISE image at about 50% of the full resolution. What do
you see that you couldn’t see when you were zoomed
out? Are there any interesting features that are small
or textures that you can see?
- Now zoom in all the way to full
resolution. Do you
see anything you couldn’t see before, like additional surface
roughness, rocks/boulders, polygons, layers, dunes?
- What observations or clues in the HiRISE image
at the various scales lead you to think there may or may not have
been water at this location in the past? Why are they important
and what can they tell you? Draw conclusions from your work. What
have you learned?
- Now try to write a figure caption. Here are some hints:
When writing an image caption, you want to first tell the reader something
about where on Mars the image is located: Is it near the North or South
pole, is it in a crater, or is it in a channel or at an intersection
of two valleys? You should have answered this in question 1.
Describe the features in the image. How large are the features
of interest in the image? Look at the browse version of the image for
an image scale. Can you see different features at different scales
(try starting from the most zoomed out scale and talk about changes
as you zoom in)?
Next, pick out a really interesting aspect of the image and describe
it. This is a good time to have a cutout, or sub image to show, if possible.
Are boulders falling down the walls leaving tracks behind them? Is the
color pattern indicating that there is frost on the tips of the dunes?
Finally, try a little interpretation and give the reader the basic idea
as to how this area ended up looking like it does: Did rivers flow down
the walls of a volcano carrying mud and water? Did wind blow sand into
large dunes in a crater floor? Did mud cracks form from the surface going
through wet and dry periods?
Take a look at some of the figure captions from the last challenge,
all labeled “Student Image of the Week:…”. You might
further explore the HiRISE website (http://hiroc.lpl.arizona.edu/images/)
for examples that are similar to your image. Don't worry about technical
jargon, just give the location, describe some interesting feature(s)
in the image, and finally give some ideas as to how it might have gotten
that way or how the features might have formed.

May we have
your permission to post information in this report on our website? If
you have suggested an image, may we have your permission to post
the teacher’s name, class, school,
location (town, state, country)? For example, with
your permission, we would like to add to the figure caption
something like: “this
image was suggested by Mrs. Smith’s 6th grade class,
Saratoga Middle School, San Jose, CA as part of the HIRISE
Quest Spring 2008 Student challenge.” If we post your
suggestion or use material from this report, how would you
like your group cited?
- Thank you very much for participating in the Spring 2008
HiRISE Quest Student Challenge. So that we may improve future
HiRISE Quest Student Challenges, could you please take a few minutes
to tell us what you liked about this challenge? What areas
need improvement? Any other suggestions or comments?j
