How many raptors are in the Starship?
The Starship bottom section houses six Raptors connected to the thrust plate: three are optimized for atmospheric pressure, and three for vacuum operation. The liquid oxygen and liquid methane propellant tanks are positioned above the thrust plate and separated by a dome. It contains a smaller spherical methane header tank. On top of the tanks is the payload section, housing a liquid oxygen header tank and payload. For cargo, a large clamshell door replaces conventional payload fairings, which can capture, store, and return payload to Earth. The payload door is closed during launch, opens to release payload once in orbit, then closes again during reentry. SpaceX also considers using the clamshell door feature to capture space debris at Earth orbit. In the crewed variant, the payload bay houses cabins and other facilities. In an interview, Musk stated that Starship would not have a launch escape system because SpaceX is confident that Starship would be safe and reliable in its finalized design.
How does the Starship work?
From its horizontal position moving at terminal velocity, Starship fires its engines to flip back up and slow itself down . Starship has two pairs of vertically installed flaps, perpendicular to the tangent line of its body. A larger pair of flaps sit at the bottom of Starship, and a smaller pair is placed on the nose cone. The windward side of the spacecraft is covered by a heat shield made from ceramic hexagon tiles designed to withstand up to 1,350 °C (2,460 °F) and prevent plasma from accelerating through the gap. The heat shield goal is to be used multiple times with little refurbishment in-between. Simulations from SpaceX showed that 99.9% of Starship's kinetic energy dissipates upon reentry to Earth, but the thinner Mars atmosphere dissipates only 99% of its kinetic energy.
What is the HLS spaceship?
Starship Human Landing System (Starship HLS) is another variant of Starship, targeted to serve as the crewed lunar lander for NASA's Artemis program. It will be developed and delivered under a contract to NASA. Starship HLS does not need a heat shield or body flaps since it will never reenter an atmosphere. This spacecraft will have a NASA Docking System, solar panels, and possibly extra landing thrusters placed in the middle of the ship to minimize dust. To fulfill the NASA contract, SpaceX will also develop two additional Starship variants required to refuel the Starship HLS to deliver it to lunar orbit: a tanker Starship and a "fuel depot" Starship. The depot will be launched into a low earth orbit (LEO) and will remain there. The tankers will carry propellant from earth and transfer it to the depot, and the HLS will transfer propellant from the depot before departing from LEO for lunar orbit. Under a separate NASA contract another variant of Starship might ferry heavy payloads to the Moon's surface for the Commercial Lunar Payload Services program.
How much thrust does a raptor have?
Both stages are equipped with Raptor engines. A Raptor engine can produce approximately 2.3 MN (520,000 lb f) of thrust. It uses a liquid methane and oxygen full-flow staged combustion cycle.
