Yes visible with binos, not a point of light more rectangular to me in the binos.

Sat in the car this morning waiting for a client I decided to work out roughly how fast the ISS was travelling. It seems if my math is correct its travelling at approx 10,000 mph ? Is this right or have mis calculated ?

It needs to travel at 15,500 to stay in orbit.

According to NASA it's...

"The International Space Station travels in orbit around Earth at a speed of 17,500 miles per hour (that's about 5 miles per second!). This means that the Space Station orbits Earth (and sees a sunrise) once every 92 minutes!"

I was only 7500 miles out lol

how crazy that immense speed and they feel no speed at all!
