When one compares that with the distance from England to the USA by ocean liner, or the distance from Chicago to Los Angeles by Route 66, hmm!

It might be more appropriate to compare the altitude of most orbiting satellites, which is apparently about ten times the closest distance that the asteroid will reach.

I think that that is for the geosynchronous satellites that are in Clarke orbit.

If I remember correctly a lot of satellites and the early manned space flights are much nearer the surface of the earth.

I know that Telstar was much lower. I remember seeing the first Telstar broadcast live from the USA one evening.

Later that evening, when the 20 minute window became available again, which was on the next orbit, a programme from England was broadcast to the USA, but I did not see that as it was on late, after I had gone to bed.

The satellite had to be tracked as it travelled across the radio-observable window.

There is a delay due to cloud cover, but they are going to try in less than 3 minutes from now.

It currently says “This live stream recording is not available.” I wouldn’t expect it to say that if the picture was just an artist’s impression.
