At 16 orbits a day, the ISS is passing over the U.S. and and can be seen from cities across the country. NBC's Brian Williams reports.
The International Space Station orbits the earth 16 times a day. But it just so happens that this week's orbit patterns bring it right over the top of some big U.S. population centers. This week you'll see a bright light moving faster than any plane across the sky -- you'll just need to get to a dark place. As you watch, remember: the ISS is home to six people, travelling 17-thousand miles an hour, and they're more than 200 miles high.

Congratulations to the Chinese for their success. I think space is big enough for everyone with the means to go and explore, and I think that humanity is better off for it.
May good fortune continue to smile on all of the space explorers both governmental and private, American, Russian, Chinese, European, Japanese, and everyone else! You raise our hopes that, one day, we shall all be able to journey through the cosmos.

For well over a year and a half or so I have been watching and during the next to last Space Shuttle Mission I was able to drag my coworker Joyce outside and while we waited she said with wonder how will we know> I said " there it is!" She stepped back and waved and said " Oh can they see us?" I laughed and told her having the Space Shuttle docked to it made it look larger. We were standing outside near the Prayer Garden at Baptist Hospital in Heber Springs, Arkansas. Since then I have watched and waited for this incredible sight wishing others shared my enthusiasm. Thank you for this news cast.

Right on schedule ISS passed over our heads...Imagine, 16 people in there and moving at 17,000 mph...thrilling!! What a world we live in. Thanks NBC and congratulations on your great website.
Thanks Brian Williams and NBC Nightly News- we watched your broadcast and went outside to look for the ISS. Low and behold around 10:16 we saw it from Carlisle Pennsylvania. It was really amazing to see. It was traveling very fast. Can't wait to tell our family and have them over tomorrow night to see it again.
Mr. Williams, Just ordinary folks wanting to be part of something BIGGER. by viewing the International Space Station; ISS. My husband keyed our daughter, my Dad and I to its exact time and location as stepped out into our small neighborhood . Three generations of our family poised ready to search the heavens. Moments later in Yorktown ,VA@ 10:10 pm she flew by high above our heads. We all thoroughly enjoyed viewing the "nighttime wonder" and waved to the astronauts so far above. Please let them know we SAW them and are humbled by their professions.
Thank you for letting us now where to find the I.S.S. It was a brief but spectacular sight flying over our back porch. We truly enjoyed it a few minutes ago!!!!! =)
Thanks Brian Williams for letting us know where to find the I.S.S. We enjoyed watching it fly over our back porch.
What a Sight!!!!! =)
Thanks for letting us know about it so we could see it tonight. We live in a tiny town called Channing, MI and with little light pollution from a big city, we had an awesome view of it. There was a blinky light moving just ahead of it which helped get my girlfriend's attention and she let me know that it was coming to find a brighter white light coming after it that was much bigger. Definitely awesome to see.
Thank you for the information on the ISS. I managed to watch it last night from my patio, even with light pollution from the city I live near, I was able to see it with no problem. This was a treat for me as I was about 9 when the space program began, never made it to see a launch in person (but oh, I wanted to), so this was the next best thing! Hoping to see it again! Thanks again!
Thanks for letting us know about the ISS on your news program! I was able to see it last night from my patio...checked the link, found the time and it was there! What a treat for someone who grew up during the early days of the space program. I'd hoped to make it to see a launch in person but never did...this was the next best thing! Can't wait for the next two nights to see if I can see it again!
The ISS android app really works great! Just watched it pass over 15mins ago!! The ISS app had it down to the second!!! And then WOW!!! There it was!!! It's a light'ish orange/rust color, really cant miss it. I wounder how many people have seen it and not realized what it actually was?!?
Kinda funny, as it was headed off out of my field of view and I was imaging the awe and wonder of space, I was immediately snapped back to life here on Earth as a June Bug hit me in the face....
Here's the link to the ISS App -
Thanks again Brian, NBC & NASA!!!
