This was the sixth test launch of the Starship vehicle, which could eventually carry humans and cargo to the moon. It was extremely loud. Also, divers have recovered seeds of a long-lost rye variety from a 146-year-old shipwreck in Lake Huron.

In the uncrewed mission, the sixth test of the system, the company was seeking to test its ability to restart the Starship engines while in orbit, a function that’s necessary for in-space maneuvering.
