SpaceX is preparing for a critical test of its Starship V3 rocket, now scheduled for May 21, after a contractor's death at the Starbase facility in Texas prompted an investigation by the Occupational Safety and Health Administration. Originally set for May 19, the launch was delayed due to this incident, which has raised concerns about worker safety and the potential impact on NASA's lunar mission timeline. The deceased worker reportedly died in a fall, although it remains unclear if the incident influenced the launch delay. Starship V3, which stands 407 feet (124 meters) tall, is designed to transport over 100 metric tons of cargo and is essential for NASA's plans to send astronauts to the moon by 2028. This upcoming flight will be SpaceX's 12th overall and aims to validate the new hardware's performance. Previous tests have faced challenges, including explosions, but the last two were successful. The results of this test could also shape SpaceX's anticipated initial public offering (IPO), projected to be the largest ever at a valuation of $1.75 trillion.
