Elon Musk's SpaceX on Tuesday launched its giant Starship rocket for a tenth test flight aiming to overcome development setbacks and clinch long-sought technical milestones key to the Mars rocket's reusable design.

In space, Starship will attempt to deploy mock Starlink satellites and reignite an engine along its suborbital path around the globe. Atmospheric reentry over the Indian Ocean will test its exterior steering flaps and an array of experimental heat shield tiles as the ship blazes through intense friction and heat.

SpaceX scrubbed a second launch attempt of its 10th Starship test flight Monday night, due to weather conditions at Starbase, Texas.
