SpaceX is changing the Falcon 9 booster recovery from Cape Canaveral to a droneship landing. The Cape Canaveral landing zone needs to be preserved for the post-explosion investigation work. There are pieces of the Crew Dragon around the landing site.
SpaceX confirms droneship landing for the upcoming ISS supply mission. Landing site not an option due to Saturday anomaly:
"To ensure the integrity of the area and preserve valuable information, we will likely attempt a Falcon 9 droneship landing during the CRS-17 mission."
