ARRIVAL From interplanetary space, the ship enters the atmosphere, either capturing into orbit or proceeding directly to landing Aerodynamic forces provide the majority of the deceleration, then 3 center Raptor engines perform the final landing burn Using its aerodynamic lift capability and advanced heat shield materials, the ship can decelerate from entry velocities in excess of 8.5 km/s at Mars and 12.5 km/s at Earth G-forces (Earth-referenced) during entry are approximately 4-6 g’s at Mars and 2-3 g’s at Earth Heating is within the capabilities of the PICA-family of heat shield materials used on our Dragon spacecraft PICA 3.0 advancements for Dragon 2 enhance our ability to use the heat shield many times with minimal maintenance
