SpaceX is set to conduct a historic rocket test tomorrow at its South Texas launch site. The company plans to fire all 33 engines on its SuperHeavy rocket during a test burn at its facility in Boca Chica. SpaceX officials say the rocket will displace more energy during the test than any other rocket in history. The test burn is part of the company's final preparation for a possible orbital launch of their Starship prototype. SpaceX founder and CEO Elon Musk has said the launch could happen late this month or sometime next month.
