SpaceX's launch marks the fastest turnaround between test flights for the world's most powerful rocket

SpaceX is poised for its next Starship megarocket test flight on Tuesday, with US President-elect Donald Trump expected to witness the second ever attempt to catch its descending booster stage in the launch tower's "chopstick" arms.

It comes just over a month after the company first pulled off the technical tour de force that underscored its position as the world leader in reusable rocketry.
