Reusability is a key strategy for SpaceX to lower the cost of orbital and interplanetary launches. With the Falcon 9 they are using the powered landing approach to recover the first stage for reuse.
Landing the Falcon 9 requires a suicide burn approach using just the the central Merlin engine. They have to time the burn just right because the Merlin can’t be throttled back enough to use a more measured, controlled landing.
With the Raptor engine being 2-3 times more powerful are they going to be able to land anything equipped with Raptor engines at all?
