Comparative Analysis of Technological Capabilities: Starliner Vs Spacex
Starliner vs spacex – Starliner and SpaceX’s Dragon 2 spacecraft exhibit distinct technological capabilities, each offering advantages and disadvantages. This detailed comparison delves into their propulsion systems, spacecraft designs, and safety features, highlighting their respective strengths and weaknesses.
Propulsion Systems
Starliner utilizes a service module powered by a single Aerojet Rocketdyne RL-10B-2 engine, providing 24,750 pounds of thrust. SpaceX’s Dragon 2, on the other hand, employs Draco thrusters for maneuvering and a SuperDraco propulsion system for emergency escape, delivering a combined thrust of 169,000 pounds.
Spacecraft Designs
Starliner features a reusable crew capsule and a disposable service module, designed to carry up to seven astronauts. Dragon 2, in contrast, is fully reusable, capable of transporting up to four astronauts and returning cargo to Earth.
Safety Features
Both spacecraft incorporate advanced safety systems. Starliner’s abort system utilizes solid rocket motors to propel the crew capsule away from the launch vehicle in the event of an emergency. Dragon 2 employs a launch escape system with eight SuperDraco engines, enabling the spacecraft to escape the launch pad within milliseconds.
