BOCA CHICA BEACH, Texas—The launch of SpaceX's second full-size Starship rocket from South Texas is now scheduled for Saturday, a day later than previously planned, according to company founder Elon Musk.

This 24-hour delay will allow time for SpaceX technicians at the company's launch facility, known as Starbase, to replace a component on the rocket's stainless steel Super Heavy booster. There is a 20-minute launch window on Saturday, opening at 7 am CST (13:00 UTC), shortly after sunrise in South Texas.

A delay at this point is unsurprising. Starship is a complex launch vehicle with a sum of 39 methane-burning engines, each producing roughly a half-million pounds of thrust, powering its booster stage and upper stage. And this is only the second test flight of SpaceX's new full-scale, nearly 400-foot-tall (121-meter) rocket, the largest launch vehicle ever built.
