  • Space is big, unbelievably big.

    Low earth orbit is roughly 200 km to 800 km in altitude.

    GPS satellites are at about 20,000 km in altitude.

    Geostationary orbit is 35,000 km up.

    The international space station is at roughly 420km altitude, travels at 27,600 km/h, yet takes 93 minutes to orbit the earth once.

    Space is just big.

    I’m addition, we track objects in orbit, this site says we track over 45,000 items larger than 10cm in size (satellites, rocket parts, debris, the ISS), with there being over a million larger than a centimetre (flecks of paint, lumps of rock/ice, small bits of debris etc). Satellites often have to move to avoid known debris (example for the ISS) and have outer shells that can absorb/disperse smaller impacts (the ISS has armour!)

    The biggest causes of debris has been countries testing out anti satellite missiles. Even small bits of debris, a fleck of paint etc can do a lot of damage when the closing speed is 10s of thousands km/h!

    Edit: fixed spelling and lower bound of LEO









  • There are different reasons against AI, it depends which ones you consider more important.

    A) taking jobs away from artists - you can argue that if you would never have hired an artist for this anyway (throw away character portrait for a D&D game) then it’s justifiable.

    B) That AI was trained on stolen content. - depends on your definition of stolen, this is the area that makes me think twice.

    C) Environmental reasons - I try to generate stuff locally if I use it, but you still have the impact from the model being trained originally.
