SpaceX is likely to land the first stage of the Falcon 9 rocket set for launch April 30 on a drone ship just off the coast of Cape Canaveral, not at the company’s onshore recovery site as originally planned, after a ground test of the company’s Crew Dragon capsule at the landing pad ended in an explosion Saturday.

The cargo-carrying SpaceX Dragon spacecraft arrives at the International Space Station and is grappled by Canadarm2 to complete a two-day journey since launch.

A cache of cargo bound for the International Space Station lifted off on a commercial SpaceX launcher Friday, thundering into mostly clear skies over Florida’s Space Coast aboard a reused booster that made a bullseye landing back at Cape Canaveral accompanied by a crackling sonic boom.
