Musk has said the plan with the Falcon Heavy is to recover “at least two of the three cores” on each flight, though recovering all three would be ideal.
And SpaceX has a good idea of what went wrong with the third landing.
The rocket needs three of the nine engines to land, and only one lit up. So that’s where they’ll start.

The new vehicles are much larger than the existing SpaceX fleet, and the large payload to
low-Earth orbit (LEO) of 150,000
kg (330,000
lb) making it a
super heavy-lift launch vehicle.
