SpaceX's Starship megarocket is set to takeoff on its sixth uncrewed flight test as early as Monday evening from Boca Chica, Texas.

SpaceX’s Starship rocket will be launched for a sixth test flight next week, the latest experiment by the Elon Musk-owned aerospace firm to create reusable spacecraft after a previous test resulted in a “seminal moment” for the company.

Meanwhile, Musk’s artificial intelligence start-up xAI has raised $5bn at a valuation of $45bn, almost double its valuation a few months ago, according to the people. The fundraising has been carried out at breakneck speed as discussions between Musk and his investors began just last month.
