You're not wrong! It looks that way because it's a reentry vehicle. You put this thing in a low orbit which decays over the course of a few weeks until it eventually falls from space, then you go find it. | ||||||||||||||

They have thrusters and do controlled re-entry, at a location of their choosing. The uppermost parts of the atmosphere are very dynamic, with changes in solar activity causing them to contract and expand on a scale of hours. And this is very significant for the amount of drag felt by re-entering objects. Because of this, if you slowly deorbit something naturally through drag, you are not going to be able to pick the destination, or even know where it ends up until very close to it falling down. So instead you intentionally lower the perigee so that it deorbits in a controlled manner. | ||||||||||||||
