A great opportunity tonight (July 28) to see three spaceships cross the sky at once! Endeavour just undocked from the ISS today, so they will be close to each other, plus there’s another spaceship lurking nearby: a Progress re-supply ship ready to dock with the ISS. How can you find out when and where to look for the three spacecraft? There are a couple of different websites that provide real-time tracking data and information about the ISS sighting opportunities. See below for more info.
The image above is a screenshot from NASA TV of the ISS as Endeavour undocked. Notice the shadow of the shuttle on the ISS solar arrays!
NASA has a Quick and Easy Sightings by City site, where you just search for your country and city which provides local times and the location in the sky where the station will be visible.
The European Space Agency also provides their ISS: Where Is It Now site that also allows you to select your country and city to find the station’s location.
The Heaven’s Above website (which also powers ESA’s site) is also an excellent site to find out when the ISS, as well as all sorts of other satellites and other heavenly sights will be visible. At Heaven’s Above, you can plug in your exact latitude and longitude, so if you live in a remote area, you’ll be able to have exact times and locations to look for satellites instead of relying on information for the nearest city.
Additionally, you can get a notification on Twitter when the space station will be zooming over your skies. Follow Twisst. (Thanks to big ian for the reminder of this new Twitter addition!)
Here’s wishing everyone clear skies and great views!
