Composite of a Series of Images Taken From Space Aboard the Station

 
This is a composite of a series of images photographed from a mounted camera on the Earth-orbiting International Space Station, from approximately 240 miles above Earth. Space station hardware in the foreground includes the Mini-Research Module (MRM1, center) and a Russian Progress vehicle docked to the Pirs Docking Compartment (right). Expedition 31 Flight Engineer Don Pettit said of the photographic techniques used to achieve the images: "My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then 'stack' them using imaging software, thus producing the longer exposure." A total of 47 images photographed by the astronaut-monitored stationary camera were combined to create this composite. Image Credit: NASA

Remembering and Visualizing

As we approach the a marker in the endless circle of life, of seasons, of the year, I reflect on the past to inform my thoughts of the future. We spend so much time analyzing our failures so we don’t repeat them. It’s equally important to understand our successes so we can repeat them, apply [...]

Amazing, sometimes, what comes back from one’s childhood—which experiences remain, perhaps subliminally, to resurface on need.

How often have you seen weather briefings that include AIRMETS, and even SIGMETS, for icing or turbulence and wondered, “Just how bad is it, really? What are the conditions up there?” Perhaps you were planning a flight, perhaps [...]
