Dust vs. Tinúviel / sound card

Taken in my room in Dabney House (alley: Upper 7) at Caltech. I had a desktop computer named Tinúviel, after the elven maiden in J. R. R. Tolkien’s The Silmarillion. I had to periodically clean the dust out of her case. The Southern California air and smog was not kind to her.

Dust Storm Over Buvinda Vallis, Mars

My job is to take pictures of Mars. How cool is that? I am a member of the science operations team for the Context Camera (CTX) aboard NASA’s Mars Reconnaissance Orbiter (MRO), which just celebrated its 5th anniversary at Mars on 10 March.

This pair of CTX images shows an area of Mars called Buvinda Vallis, a valley adjacent to the volcano Hecates Tholus at ~32°N, 207°W. In an attempt to get stereo (3D) coverage of the area, we shot the valley in February 2009. When we came back less than a month later to acquire the second image in the stereopair, a local dust storm obscured part of the image. Atmospheric dust tends to make CTX images look pretty bad (noisy). However, in this case, what we captured were some spectacular dust clouds in the southern portion of the image. The small white speck to the east of the crater near the center of the image is a dust devil.

Each image is 30 km wide. North is slightly to the upper right and illumination is from the left. Taken during autumn in the martian northern hemisphere.

Question by skipr12: How do you make the drop down arrows appear permanently for the drop down boxes created in Excel?
I have created drop down boxes in Excel. When I click on the cell that contains the drop down box, the arrow appears on the right. When you go to a different cell, the arrow disappears. How do you display these arrows at all times so that the user knows which cells have drop down boxes available?

Thanks in advance for the help.
