When can I spot the Space Station? The International Space Station can easily be spotted with the naked eye. Because of its size (110m x 100m x 30m) it reflects very much sunlight.
This simple tool will tell you all of the opportunities you can view the ISS over the next ten days, along with a brightness index and a map tracing its transit across your local sky. The red line shows where the ISS is sunlit and visible. On the blue line the ISS is in the Earth's shadow and invisible or it is less than 10° above the horizon. [more inside]

The United States Department of Defense has generously
"decided to give NASA two telescopes as big as, and even more powerful than, the Hubble Space Telescope." They apparently had some antiquated spy satellite hardware sitting around unused and unwanted. NASA still needs to find money to outfit them with recording instruments and pay a team to manage them, which may take 8 years

The World at Night. This amazing image
(warning 500K) is actually a composite of hundreds of pictures made by the orbiting DMSP satellites over regions of the world at night. You can clearly see the Nile river, Hong Kong, Hawaii and probably, if you look close enough, the town you are in right now. From Astronomy Picture of the Day

This reminded me of one of the stupidest things I've ever seen.
Once on vacation in Eastern Oregon, there was a total eclipse of the moon, just like this one. And some people nearby were taking photographs of it.
photographs. The round-trip time to the moon at the speed of light is 3 seconds and I wouldn't even want to calculate the attenuation caused by 320,000 miles of range.
Sometimes it seems as if some people are completely and totally clueless about what they're doing.
