ISS sighting opportunities

Spot The Station will give you a list of upcoming space station sighting opportunities for your location. [Klaatu, Mar 09 2016]

On the ISS, the top and bottom are referred to as "zenith"
and "nadir", with the "nadir" direction being pointed toward
Earth at all times, and that's the side with the multi-
windowed cupola on it. |

// My wife and I saw the ISS go by yesterday evening // |
|
| |
Were you in a parking orbit, then ? |
|
| |
// the "nadir" direction being pointed toward Earth at all times // |
|

The irony of that statement is breathtaking... |
|
| |
64,800 degrees ? That's one really smart photo ... |
|
| |
Or a hot one. Never predicted Ian as a supermodel. Sorry
Ian... |

If this would work, it is a brilliant idea. |
|
| |
If not, please disregard the foregoing. |

It does seem like the total number of degrees or degrees^2
would be 360*^2 or 129,600. |
|
| |
If it was an ISIS weathervane would it feature a headless
chicken? (Probably not in good taste) |

I'm not entirely certain, but if the solar wind were "blowing" hard enough to affect this device, the astronauts and cosmonauts within would have received a fatal dose of radiation. |
|
| |
[WcW] - you're on the right track: it's actually 129,600 / pi
square degrees in a sphere; or about 41,253 deg^2. |
|
| |
// a fatal dose of radiation. // |
|
| |
Not necessarily. The "solar wind" which gives rise to auroral phenomena consists mostly of charged particles, not energetic photons, and can be blocked effectively by a very modest thickness of metal. |
|
| |
The danger arises more from "cosmic rays" which are ionizing and highly penetrating photons. |
|
| |
It'll need some sort of scrolling read-out so the cock can doodle too. |

// which direction on a space station is “atop”?// No gravity: it's all "atop". |
