SpaceX launched the seventh test flight of its Starship rocket on Thursday, as Elon Musks's company looks to push development of the mammoth vehicle further, including with a crucial test for how it will deploy satellites.

SpaceX launched Starship on Thursday for a seventh test flight, after weather concerns pushed back an experiment that will feature the spacecraft’s first payload deployment test, and while it successfully caught the Super Heavy Booster, SpaceX lost communication with Starship shortly after.

Elon Musk’s spaceflight company is continuing its work on the vehicle that could one day take people to the moon and eventually Mars.
