The International Space Station
Can you image this in your back yard?
This thing is about the size of a football field
While supper was baking in the oven Carol and I spent 4 minutes at dusk watching the
International Space Station (
ISS) pass to the north of us in it's orbit of earth. With the help of
NASA's Satellite Sighting Information webpage (follow the links under the title "Sighting Opportunities") It's easy to step outside at the right moment to find its appearance in the sky and you may be surprise how often you can see it if you have a good sky view. What you are seeing is a bright star about the brightness of Jupiter moving along at a high rate of speed, much faster relative to us on the ground than a passenger jet high in the sky. The
ISS is traveling at 12,000 mph I believe. Sometimes the angle is relatively low so if you are surrounded closely by trees and/or buildings you may have to wait for a time when it passes close to directly overhead. The times I've used are all near dusk as there are no flashing lights to see, only the reflection of the sun on the
ISS itself. I had discovered the
webpage last fall after having spotted the fast moving light one evening and knowing that neither of the space shuttles were in orbit I figured it was the
ISS so I looked it up on the web. Since the time change and the approaching winter I haven't taken the time to see when there might be some sightings coming up. But tonight I did, and four minutes is a long sighting. There was also a sighting for a few seconds about an hour and a half later which I caught barely above the treetops to the west-by-northwest direction. Monday at 5:25pm in my region is a six minute sighting. Yes, its only a light in the sky but considering what it represents I feel a little awe
everytime I see it.
