The SpaceX CRS-8 capsule carried a space station module.
CRS-14, SpaceX's fourteenth CRS mission, was the third reuse of a previously flown Dragon capsule
 The capsule uses a PICA-X heat shield, based on a proprietary variant of NASA's Phenolic impregnated carbon ablator (PICA) material, designed to protect the capsule during Earth atmospheric entry, even at high return velocities from Lunar and Martian missions
