SpaceX's most powerful rocket ever built is now even bigger and more powerful. But will it work?
The Version 3 prototype adds lighter Raptor engines and a taller design as SpaceX seeks to solve key lunar mission challenges.
On Thursday, SpaceX scrubbed its Starship megarocket test flight after a pin holding the launch tower's arm failed to retract, scheduling another attempt for the following day at 7:30 p.m. EST.
SpaceX employs a 'rapid iterative development' strategy, maintaining that explosive errors are integral to its engineering approach to accelerate design adjustments more cheaply than traditional aerospace methods.
The new Version 3 prototype features head-to-toe upgrades, with 33 Raptor engines each delivering more than 50,000 additional pounds of force at liftoff, according to SpaceX.
Sean Duffy, who briefly served as NASA's acting administrator last year, announced the agency will use whichever lander—SpaceX's or Jeff Bezos-founded Blue Origin's—is ready first for the 2028 mission.
Competition intensifies as China plans to land taikonauts on the moon by 2030, while NASA lacks a functional landing vehicle despite celebrating the recent Artemis II mission.
