2. Research question Worked on by Gary • Where are double wind streaks mostly found? • Why is your science question important?It can help show scientists studying Mars the direction of the wind. It also shows where the wind blows strongly on the red planet. • Why is your science question interesting? Wind streaks are cool, because they come in different colors and shapes, but when you see a wind streak in different directions on a single crater, it looks even better.

4. Worked on by Ben Background Information Slide #1 • Definition- Most wind streaks on Mars are associated with geographic obstacles, and the streaks form in response to a lot of wind around those obstacles. • Wind Direction- Whichever way the wind streak is pointing in, is the way the wind is blowing on Mars. It works the same way on Earth, and every planet that has wind. history.nasa.gov/JPL-93-24/ch6.htm

5. Worked on by Ben Background Information Slide #2 • How They Are Created- The result of erosion and deposition • Types- Most common types of wind streaks are bright and dark streaks, which are mostly connected to craters, or hills • Dark Wind Streaks- Dark streaks are created when the bright dust is blown off the surface of the wind streak. http://ougseurope.org/rockon/surface/windstreaks.asp

6. Worked on by Josh and Ben Background Information Slide #3 • Still Active- Some wind streaks have been seen to change in short amounts of time, indicating that the erosion and deposition that formed them is active right now! • Shape- Wind Streaks are tear-shaped features seen behind craters, ridges or cliffs. http://www.lpi.usra.edu/publications/slidesets/winds/ http://www.lukew.com/marsgeo/aeolian2.html

7. Worked on by Gary and Ben Hypothesis • Josh, Ben, Gary, Isaiah, Leila’s Hypothesis. If there are 120 pictures of double wind streaks, then by looking at the pictures of double wind streaks most will be found in southwest, because there are a lot of craters there. • Logan's Hypothesis. If there are 100 pictures of double wind streaks, by looking at double wind streaks, most wind streaks will be found near the south pole, because there are a lot of craters there will be a lot of wind streaks.

Worked on by Isaiah Procedures Website list : http://themis.asu.edu/ 1) Go to the website http://themis.asu.edu/ 2) Click on the wind/dust topic • http://themis.asu.edu/node/5757 • Look for pictures of wind streaks. Then put them into categories, double wind streaks and regular wind streaks. An image will be useful if it has wind streaks, especially if it is a double wind streak. • We put all the pictures we find into a Microsoft Excel document, categorized by lat., Long., and # of streaks.

12. Data

16. Discussion

17. These are all the examples we found of double wind streaks. We were only able to find a few double wind streaks, and few wind streaks as well. This data is relevant to what we were finding, because we were interested in wind streaks with more than one streak on the obstacle, and I didn’t think we were going to find any, but it turns out there is! This data is important, because it helped us do the MOLA map, which was extremely difficult.

18. We found out from this MOLA map that all of our double wind streaks were somewhere near the Martian equator. This also lead us to think that maybe the most forceful wind happens near the equator. Most wind streaks in general happened near the equator too.
