The white paper says the payload release doesn't have to be precisely timed, if TARS is on a circular orbit, and I do not understand why. Sure, the plane in which the payload shoots off, is defined by the orbital position of TARS. But there are 360 degrees of freedom within that plane. If we aim at e.g. a specific star, how is release timing not a critical factor? And if it is, what timer would survive the solar radiation and extreme spinning, remaining reliably operational and microsecond accurate?

Are you talking about this?

My understanding is that it means it does not have to be precisely timed with regard to velocity, but has to be with regard to angle.

The timer would not need to be onboard the spinning flywheel, it could be on an observing quasite orbiting higher. When it's time to launch it could shine a control laser at the flywheel, which is used to time the triggering of a cutting laser at the right position to slice the payload off at the correct angle.

One timer could be used to launch multiple flywheel payloads over time
