You get sales alerts, Twitter alerts, sports alerts and Facebook alerts. Now you can also get an alert when the International Space Station is visible overhead thanks to NASA's new Web app Spot the Station.
The International Space Station's orbit 200 miles above Earth makes it visible to more than 90% of the Earth's population, NASA said. The trick is knowing when to look for it.
NASA's Johnson Space Center already calculates the sighting information several times a week for more than 4,600 locations worldwide. With its new Web app, it is just sharing that information with the space-obsessed public.
As long as you know where to look, the International Space Station is pretty easy to see, NASA said. It is the third-brightest object in the sky after the sun and the moon, and it looks like a fast moving point of light about the size and brightness of the planet Venus.
