Interesting talk today on X-ray. I like learning about the history of telescope projects. It reminds me that learning takes time. Time to ask a question you can try to answer, time to build an instrument that can make a measurement that can help you answer your question, time to analyze the measurements and compare them to models. Our country has to be willing to be patient and wait for answers while funding the projects.
- The Splitting of the Dunes
The mound in the center of this Mars Reconnaissance Orbiter image appears to have blocked the path of the dunes as they marched south (north is to the left in this image) across the scene. Smaller dunes run perpendicular to some of the larger-scale dunes, probably indicating a shift in wind directions in this area.
