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.

SpaceX is scheduled to launch its sixth uncrewed test flight of Starship on Tuesday to expand the massive 400-foot rocket's booster capabilities and bring its "catch and reuse" launch system online.

Donald Trump’s visit comes as billionaire Elon Musk has been present at the president-elect’s side as Trump continues to make cabinet nominations for his administration.
