Feeding astronauts requires science, engineering, and a deft hand with spices. The difficulties of eating in micro gravity include problems of stray crumbs or drops of fluid floating around and lodging in equipment. That means, for instance, that salt and pepper have to be in liquid form. Physiological changes in low gravity include constantly blocked sinuses, which adversely affect human senses of taste and smell. The problems of cooking in very small spaces, with limited access to water, or refrigeration, or even power, and of disposing of packaging materials are also substantial. In space, everyone cleans their plates.
Astronomers first spotted—and drew pictures of—Jupiter's "Great Red Spot" some 300 years ago. It's that "eye of Sauron" spot on the Southern Hemisphere. In reality, it's a very large, very ancient storm, and as the weather on Jupiter changes, so does the Spot. The Spot really is properly called "Great"; it is so far the largest known storm in our Solar System, with a diameter of 15,400 miles. In other words, just the area covered by the storm on Jupiter is almost twice the size of Earth (and about one-sixth of Jupiter’s diameter). We've been watching the spot long enough now that we can see it is definitely shrinking. What's more, as currents and weather patterns shift, we've witnessed, albeit at a very great distance, new storms and smaller spots appearing in Jupiter's images.
At 02:56 UTC on July 21 (10:56pm EDT, July 20), 1969, Astronaut Neil Armstrong began his descent to the moon's surface, and spoke his now famous line: "One small step for man, one giant leap for all mankind." We've all seen the video:
Recently, the video from the special 16 mm Data Acquisition Camera mounted in the lunar module has been widely available. The camera could be set to normal speed, or to one frame per second, to save film. For the moon walk, the camera was set to normal speed.
