			===Version 2===
			In 2024 Elon Musk described the next version of Starship (version 2) which would be 1.8 meters taller. This featured a new forward flap design (to minimize heating in reentry), increased propellant capacity, and an increase in thrust. This ship will be used from Ship 33 and subsequent flights. <ref>https://www.youtube.com/watch?v=umdkFlNO1os </ref> It is not yet known how much this will change the mass to orbit / to Mars.

	'''Starship''' is the name of the 2019 version of the second stage of the [[SpaceX]] reusable super heavy lift vehicle, resting upon the [[Booster\|Super Heavy]] booster. The term "Starship" may also be used to refer to the complete stack of both stages. SpaceX’s Starship spacecraft and Super Heavy rocket (collectively referred to as Starship) represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. Starship will be the world’s most powerful launch vehicle ever developed, with the ability to carry in excess of 100 metric tonnes to Earth orbit. Starship will enter Mars’ atmosphere at 7.5 kilometers per second and decelerate aerodynamically. The vehicle’s heat shield is designed to withstand multiple entries, but given that the vehicle is coming into Mars' atmosphere so hot, we still expect to see some ablation of the heat shield (similar to wear and tear on a brake pad). The engineering video below simulates the physics of Mars entry for Starship.<ref>[https://www.spacex.com/vehicles/starship/]</ref>		'''Starship''' is the name of the 2019 version of the second stage of the [[SpaceX]] reusable super heavy lift vehicle, resting upon the [[Booster\|Super Heavy]] booster.

			If SpaceX is able to make this ship work, with rapid turnaround, the cost of launching a kg into Low Earth Orbit will decrease at least ten fold. This will make all space projects (including Mars missions) much cheaper.

			==Launch pads==
			Two launch areas have been built or are under construction. One in Texas, one in Florida. The launch towers that service the vehicle stack use mechanical arms to move the vehicles, and are projected to be used to catch the vehicles at landing time, reducing the mass of the vehicles but adding a requirement for very precise position control at landing.
