Space Station Marathon Starting This Weekend
RobGoldsmith writes with this snippet from Space Fellowship: "If you've never seen a spaceship with your own eyes, now's your chance. The International Space Station (ISS) is about to make a remarkable series of flybys over the United States. Beginning this 4th of July weekend, the station will appear once, twice, and sometimes three times a day for many days in a row. No matter where you live, you should have at least a few opportunities to see the biggest spaceship ever built."
Another source for flyby times for the ISS and more. Plus, no java required. http://www.heavens-above.com/
As mentioned in the article, you can get fly-by information from Nasa's ISS tracker
Health Freedom is almost as popular as Freedom itself.
For instance:

The good flybys are periodic: the station needs to be in the brief region of space where it's not in the penumbra or umbra of the earth, but is visible from points on the ground that are in darkness, so the sky does not overwhelm the reflection. That happens on every or nearly every orbit. But the parts of the earth that are lucky enough to have that view varies by time of year.
You can use NASA's satellite finder to view the time when it will pass over your city.
I looked it up for Mexico City and there are two great citing opportunities there, five or six minutes long. Vancouver has over a dozen, better than in my city, and Toronto has many sighting opportunities as well. Suffice it to say, the best ones will likely be from 8 to 11pm local time, and the ISS will be only available for five or six minutes at most.
The last time the ISS flew over my city, I was ready at hand with my dinky 70mm telescope, which I've had a lot of trouble being able to steady despite having it for a year. By the time I had the knobs adjusted right such that it wouldn't slide down as I put my eye to it, I had to run with my telescope after it to a better spotting place before it disappeared with the horizon. It appeared in my viewfinder as two distinct overlapping yellow blurs, but I'm sure I saw it and this time I'd like to try again with a camera.
Seems to me this would be a fairly common occurrence, as it orbits the earth many times a day, every day, all the time.
This is the website where you find the latest sighting opportunities for your location.

Go to +REALTIME DATA / Sighting Opportunities then, choose your country and the rest should be self explanatory, at least for the United States which is all I have used this website for :)
Not the italian guy again ... Hey, Gaetano, DIRECT was NASA's idea in the first place (by about a decade and a half); See the National Launch System.
None of the DIRECT engineers or face people deny this fact. Thus, the only one who is falsely claiming ownership of the concept is you!
