SpaceX will launch Starship for a seventh test flight on Thursday, after weather concerns pushed back an experiment that will feature the spacecraft’s first payload deployment test, in what may be the latest milestone for the Elon Musk-owned aerospace company as it develops reusable rockets.

SpaceX readies its seventh test flight of Starship, the most powerful rocket ever designed. The trial will test upgrades to the spacecraft and deploy mock satellites.
