On A Clear Day You Can See Forever. This is the title of a romantic musical movie in 1970 which was sung by Barbra Streisand.
What does it have to do with the International Space Station? Nothing really, but if the skies are going to be clear this coming Friday to Sunday, you might have a chance to see it, according to the press release from NASA
It’s orbiting us at a height of 431km and at a speed of 66 kilometer per second. That’s faster than anything here on earth. However, since the distance from earth and the space station isn’t quite as far as the moon, human eyes can perceive it with a little difficulty, if the weather permits. It won’t be long, but it’ll be enough to give us an opportunity to see it traversing the earth’s atmosphere, which is about 480 kilometers high.
The space station will be visible for three minutes this Friday, beginning at 6:38 p.m. It will be moving towards the southwest, becoming visible 10 degrees just over the west-northwest horizon.
If you miss it, on Saturday it will visible for much longer, about six minutes this time, beginning at 5:47 p.m. This time, it’ll be visible just 10 degrees above the northwest horizon moving to the southeast.
Sunday, the space station will be visible again for one minute, starting at 6:35 p.m. You’ll find the station 13 degrees above the southwest moving towards the south-southwest.
And if you miss all these, you’ll still have another chance of seeing the space station on Sunday at 6:35 pm. It will be 13 degrees above the southwest, heading towards the south-southwest.
You won’t really see it as it appears on the pictures; instead, it will appear more like a shining metal ball in the sky. A simple scan with your bare eyes or a better view with a telescope will end up the same: it will still appear like a metal ball.
