SpaceX's Starship Launch Attempts: Scrubs, Concerns, and Evolution.

SpaceX is targeting April 20 for the second attempt to launch its fully stacked Starship vehicle to space from its facility in South Texas. The launch window opens at 9:28 a.m. EDT and the mission calls for Super Heavy to make a hard splashdown in the Gulf of Mexico about eight minutes after liftoff, while Starship's upper-stage spacecraft will make a partial lap around Earth, coming down in the Pacific Ocean near Hawaii around 90 minutes after launch. This will be the debut spaceflight of a powerful and complex vehicle, so SpaceX is measuring success by how much they can learn to improve the probability of success in the future.
