It is quite curious that this comic was published exactly when an italian wannabe astronaut (twice discarded by ESA) finally managed to get into outer space by having the italian armed forces pay for his ticket, so now he's on ISS as a *guest*. Of course it's impossible that Randal was hinting at this, but it's an amazing coincidence. --[[Special:Contributions/172.71.114.175|172.71.114.175]] 17:26, 20 January 2024 (UTC) | It is quite curious that this comic was published exactly when an italian wannabe astronaut (twice discarded by ESA) finally managed to get into outer space by having the italian armed forces pay for his ticket, so now he's on ISS as a *guest*.

− | Noting in the Explanation that the length of the ISS solid angle 'area' is going to be a footprint slightly smaller than the stated size of the ISS (not by much, as it isn't really that far up, compared with how far the centre of the Earth is down, but it ''will'' be smaller. Also that (by my own from-first-principle calculations - please ''do'' check my stated working assumptions given in the relevent Edit Summary, or just do it yourself from scratch) slightly over a fifth of the Earth's surface ''never'' gets to experience the ISS being directly overhead. I was going to enumerate the sort of 'general chance that any given point at any given latitude might have the ISS above it', perhaps then to shove overflying speed (assuming zero eccentricity - which it pretty much is), compared with any given proportion of a surface latitude (assuming zero Earth oblateness - even though it is certainly a little bit, even at first approximation). But that seems overkill to actually Explain. Though I think it ''will'' make an interesting graph of +/-latitude vs overlfly 'timeshare' so I'll perhaps do that for my own entertainment momentarily. | + | Noting in the Explanation that the length of the ISS solid angle 'area' is going to be a footprint slightly smaller than the stated size of the ISS (not by much, as it isn't really that far up, compared with how far the centre of the Earth is down, but it ''will'' be smaller.
