- Get the rocket safely back to earth
- Transport rockets via a ship
- Disassemble and move them on port
- Pack, cover and send them back to hangar
- Inspect, clean and replace the parts
- Reassemble and move them out to different warehouse
- Maintain the rocket till its next launch date
- Send rocket back to flight hangar
These processes (and possibly industry) literally did not exist years ago. It's a completely different challenge.
