Elon Musk will participate in The Wall Street Journal's CEO Council Summit, where he will address questions about his various corporate endeavors. Musk has been actively involved in turning around Twitter, boosting demand for Teslas, and proving the capabilities of SpaceX's Starship rocket. Musk's virtual appearance at the summit comes shortly after announcing his plans to step down as CEO of Twitter, with Linda Yaccarino, former head of advertising at NBCUniversal, taking over the role. SpaceX has set aside $2 billion to develop its Starship rocket for lunar and Martian missions, despite a setback in the inaugural test flight. With a goal of 100 launches in 2023, SpaceX aims to support its satellite-internet business, Starlink, which already has a customer base of over 1.5 million worldwide.
