Before the maiden SpaceX launch of Starship, the most powerful rocket ever constructed, Elon Musk had modest expectations.

Elon Musk's SpaceX is preparing to launch its own vehicle, called Starship, which could pack nearly twice the power of anything flown before. The company is targeting liftoff at 8 a.m. CT (9 a.m. ET) on Monday, although it has the ability to take off anytime between 8 a.m. CT (9 a.m. ET) and 9:30 a.m. CT (10:30 a.m. ET).

SpaceX CEO Elon Musk has set expectations low and warned those in the area to stay away from the "Keepout Zone" — the areas directly surrounding the launch site that have been deemed too close to the rocket to be safe during lift off. Locals are known to line the surrounding beaches in South Padre Island to watch tests, and this launch is sure to draw spectators.
