SpaceX has turned heads and tested boundaries with each test flight of Starship, the most powerful rocket system ever constructed. And the latest mission of the nearly 400-foot-tall (121-meter) vehicle is designed to push the envelope even further in a quest to return astronauts to the moon and someday fulfill CEO Elon Musk’s dream of sending the first humans to Mars.

The latest flight of the SpaceX Super Heavy-Starship includes multiple upgrades to improve safety and performance of the world's most powerful rocket.

SpaceX will launch Starship for a seventh test flight on Wednesday, an experiment that will feature the spacecraft’s first payload deployment test, marking what could be the latest milestone for the Elon Musk-owned aerospace company as it develops reusable rockets.
