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.

SpaceX’s giant Starship rocket is slated to launch for the seventh time on Thursday in a crucial test of its ability to carry and place satellites into orbit.

The 21 satellites from the Starlink company, owned by SpaceX, will be heading to low-Earth orbit to join the thousands already there. And 13 of them have direct to cell capabilities, explained Starlink. Once deployed and in their orbit, they will provide internet service to many parts of Earth.
