Departing from Boca Chica, Texas, SpaceX plans to launch its 160-foot-tall prototype Starship spacecraft 12.5 km (41,000 ft) above the surface and return safely to its launch site. The company has set up a launch window for ET at 5:30 pm, and you can watch it live via SpaceX’s YouTube channel. There are plans to conduct this test for several months. Originally planned to fly at 60,000 feet, the mark was lowered to 50,000 feet in September and then lowered again. However, following a successful static engine test in late November, SpaceX CEO Elon Musk announced via Twitter that the company was advancing to a higher altitude test and would conduct it “immediately”. It turns out that today means.
