Taking off from Boca Chica, Texas, SpaceX plans to launch its 160-foot tall prototype Starship spacecraft to a height of 12.5km (41,000 ft) above the surface and safely return to its launch pad. The company has set a launch window beginning at 5:30 pm ET and you can see it live through SpaceX’s YouTube channel.
Plans have been in place to conduct this test for several months. Originally slated to fly as high as 60,000 ft, that mark was reduced to 50,000 ft in September and has since been lowered once more. However, following a successful static engine check-in in late November, SpaceX CEO Elon Musk announced through Twitter that the corporate was pressing forward with the high altitude test and would conduct it “imminently.” Turns out that meant right this moment.
