The are a few cool milestones that may well occur this year for SpaceX, beyond just their manifest ripping by at a clip:
- The reuse of a Dragon capsule that's already been to the ISS.
- a propulsive landing of a Dragon capsule that's been at the ISS (this would be absolutely amazing to see).
- the reuse of a previously launched F9 first stage.
- The first launch of a falcon heavy.
All, none or some of these could happen this year. Exciting!
