“Starship Overview
SpaceX’s Starship spacecraft and Super Heavy rocket – collectively referred to as Starship – represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. Starship will be the world’s most powerful launch vehicle ever developed, capable of carrying up to 150 metric tonnes fully reusable and 250 metric tonnes expendable.”

Size comparison with Apollo.
The first attempt at a full launch is due tomorrow evening our time. It is planned to orbit, re-enter, “fly” down to near the surface, rotate to vertical and try to “land” vertically on the surface of the ocean. It will then fall over and likely be recovered.
There are many modes of failure, rocket science is hard. It would be very unlikely that it worked first time, but we can only hope for the best.
