Great topic
Been listening to Rogan(don't hate, it's a time killer at work) and his discussions about aliens are awesome.
But yeah, space.... It's dark.
Stikman is a fan

I would assume it’s because it is flying back to earth in a controlled manner from “not too high” whereas the other ships plummet back from much higher. I was watching an Apollo doco a few weeks back and I think from memory that was coming back at over 10,000 km an hour |

Stikman is a fan Rogan is an amazing interviewer. The vast array of guests he has and how he is able to hold interesting conversations with all of them for hours on end shows a real talent. He can talk just as easily with astro physicists or meathead MMA guys. |

Great info. so how far is the space station then? normal satellites? those starling satellites? I know they are lower than normal ones |

Great info. so how far is the space station then? normal satellites? those starling satellites? I know they are lower than normal ones The ISS is about 400km high. Satellite vary greatly on their intended purpose, if they need to match the rotation of the earth then they are up to 36,000km out, the majority are between 160-2000km. Have a read of this regarding re entry and the associated problems.
