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.

A commercial Falcon 9 rocket in the final stages of launch preparations fired its nine Merlin main engines Saturday at Vandenberg Air Force Base in California, verifying its readiness for liftoff with a Taiwanese Earth-imaging payload Thursday.

A United Launch Alliance Atlas 5 rocket launched at 5:02 p.m. EST (2202 GMT) Thursday from Cape Canaveral with NOAA’s GOES-S weather satellite, the second in a series of upgraded observatories destined to cover the western United States and the Pacific Ocean.
