Are these trees on Mars? (No…but they sure do look like trees!)

Wake up with IR! Here's today's dose of Caffeine Priority
Well, you could have fooled me. I'm surprised I missed this image when it was initially released, as I generally visit the Astronomy Picture of the Day page first thing every morning over coffee. Sure enough, they are for sure not trees, and in fact they don't protrude at all as they cast no shadows.
But if not protrusions.... what then?
Images from the cosmos get ever more interesting the further we explore and the farther we can see with modern imaging technology. For the planet Mars, this has meant HiRISE, the High Resolution Imaging Science Experiment. And boy, what an experiment! Its imager can resolve objects on the Martian surface of roughly a third of a meter, and in 2006 it began capturing and beaming these high resolution images back to Earth.
So obviously this isn't at all new to the science community, but I'd simply never seen this particular image and wanted to share it with our readers who also may have yet to see it. And those tress? They're actually dark sand streaking down dunes near the Martian north pole!
Traveling onboard the Mars Reconnaisance Orbiter and courtesy of the folks at the University of Arizona Lunar and Planetary Laboratory, HiRISE has become known as "The People's Camera" as the general public has been involved in both the decisions on what to photograph (via HiWISH) and in being given virtually unlimited access to the images created by HiRISE. As of this writing there are now almost 40,000 (!) images for you to enjoy, study, and download, so you really have no more excuse for boredom because there are some truly stunning images, and the Martian landscape is so much more diverse than we'd ever imagined before HiRISE.

Caffeine Priority is a new series of short photo-tidbits to ease you into your day, and give us a chance to share a bit more of what life’s like here at IR. We're more like a group of friends testing and talking about cameras and lenses than the buttoned-down, big-corporation world that some of our photo-friends at other companies work in; hopefully these little snippets will share some of that. So... grab another coffee and join in the conversation with us down below!
