Elon Musk, SpaceX aim to launch SN15 Mars rocket prototype Tuesday - CNET

Tuesday is the latest target date for a launch of the newest Starship.

After four successful test flights of SpaceX's next-generation rocket prototypes all ended in dramatic explosions during the landing phase, Elon's Musk's space company is skipping ahead to SN15, a new version of its interplanetary vehicle.

It has hundreds of design improvements across structures, avionics/software & engine.

Musk has said SN15 "has hundreds of design improvements across structures, avionics/software and engine," including, hopefully, upgrades to cover some of the problems that have prevented SpaceX from sticking the landing so far without a rapid unscheduled disassembly.

Last Thursday the FAA said it had approved a launch license covering SN15, SN16 and SN17, but it currently looks like we'll have to wait till at least Tuesday to see it fly, according to current airspace, road and beach closures around the Boca Chica, Texas,  launch facility.
