In January of 2021, Elon Musk announced SpaceX’s latest plan to increase the number of flights they can mount by drastically reducing turnaround time. The key to this was a new launch tower that would “catch” first stage boosters after they return to Earth. This would forego the need to install landing legs on future Super Heavy boosters and potentially future Starship returning to Earth.
