In an article posted at http://www.nasaspaceflight.com/content/?cid=4727 "'The most visible legacy will be the International Space Station. When it's completed, we'll see it as a star in the sky, even during the day,' noted (Robert) Lightfoot in MSFC's internal magazine Marshall." This is the first I've heard of this possibility... almost hard to believe. Has anyone else heard of this? ------------------

I've heard that said for years. Don't know enough to comment on its veracity.------------------

I vaguely remember heard about this but I don't know if it refers to the current planned design or if it referred to the "dual keel" version envisionned in the late 80s. But the fact that it could be seen in daylight was due to the sun reflecting on the station's solar panels, when complete. Again, whether that applies to the present configuration, I don't know.

Its certainly possible during dawn/dusk at viewing site and ISS coming up/going down from the dark side. For rest of daylight hours I would expect that it would need to be an exceptionally clear day at view site (no clouds or haze layer), deep blue sky and viewer perhaps directly underneath flight path? Also to have some form of optical aid (binos/scope). I wouldn't think it would be visible naked eye but would like hear if anyone has seen it naked eye during daylight hours.

With a telescope it is possible to see it in the daytime even now, much as you can the brighter planets and stars.But, I think what he means (as in naked eye) is simply being able to see it in technical daytime; very close to sunset or after sunrise. Or perhaps even including the 15 minutes before and after as 'daytime.' NASA, for examples, considers a 'daytime' launch to be any launch from 15 minutes before sunrise to 15 minutes after sunset. |

It should be pretty easy to spot. If you know where to look, Venus can be seen during the day with the naked eye. Saturn and Jupiter can be seen during daylight also with a telescope. Here is Saturn from a sunny afternoon in blue sky from my backyard.  |
