Starlink satellites are launched in batches of 60. They are released from the launch vehicle, and then have to spread out – not only into equidistant slots along a single orbit ring, but now apparently into separate orbit rings (72 rings of 22 satellites).
Since this is rocket science and fuel is precious I imagine there is some clever maneuvering to get the satellites from what is essentially a single point of release into these widespread orbits with minimal fuel consumption. So how do they do it?
(All I've been able to find so far is this answer which notes that the fairing carrying each batch increases its spin rate as each satellite is deployed, which imparts some momentum. I'd be curious as to how much of that contributes to the energy needed to get each satellite to its final orbit and slot.)
