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.

The latest flight test comes roughly a month after the Super Heavy booster was successfully caught by two robotic arms and returned to the launch site during the Starship's fifth flight test. The sixth flight test hopes to build on that momentum with upgrades made to both hardware and software controls.
