The evolution of spacecraft design from the Apollo era to the modern era of SpaceX has been a remarkable journey marked by significant advancements in technology and design. While the Apollo spacecraft were a marvel of engineering at the time, they were limited in their capabilities and were designed for a specific set of objectives, mainly landing humans on the moon and returning them safely to Earth. In contrast, SpaceX spacecraft are designed to be reusable, with the goal of enabling sustainable exploration and colonisation of other planets.
In this article we will provide the complete overview of evolution in spacecrafts from Apollo to Spacex including advancements in space technology and spacecraft designs, similarities and differences between their designs and functions and impacts of advancements on space exploration and technology.
Advancements in Space Technology and Spacecraft Designs
There have been numerous advancements in space technology and spacecraft design between the Apollo era and the modern era of SpaceX. Some of the key advancements include:
Reusable Spacecraft: One of the major advancements between Apollo and SpaceX is the development of reusable spacecraft. Apollo spacecraft were not designed to be reusable and were discarded after each mission. SpaceX, on the other hand, has developed fully reusable spacecraft, such as the Crew Dragon and Starship, which are designed to reduce the cost of spaceflight and enable more frequent missions.
Autonomous Landing Systems: The Apollo spacecraft had to be manually landed by the astronauts, while SpaceX spacecraft are equipped with autonomous landing systems that can safely land the spacecraft without human intervention. This has significantly improved the safety and reliability of spacecraft landings.
Advanced Rocket Engines: SpaceX has developed advanced rocket engines, such as the Merlin and Raptor engines, which are more efficient and powerful than the engines used during the Apollo era. These engines enable SpaceX spacecraft to travel further and faster than was possible with Apollo spacecraft.
Commercial Spaceflight: Another significant advancement between Apollo and SpaceX is the growth of the commercial space industry. SpaceX has been a key player in this industry, providing launch services for private companies and government agencies, such as NASA. This has opened up new opportunities for space exploration and has made spaceflight more accessible to a wider range of people and organisations.

Similarities and Differences between the Designs and Functions
There are several similarities and differences between the design of the spacecraft used in the Apollo program and those used by SpaceX:
Similarities
- Both Apollo and SpaceX spacecraft consist of multiple modules, including a command module and a service module.
- Both spacecraft were designed to carry humans and cargo into space.
- Both spacecraft are equipped with propulsion systems to enable them to manoeuvre in space and travel to their destinations.
- Both spacecraft have used docking systems to connect with other spacecraft or space stations.
Differences
- Reusability: The Apollo spacecraft was designed to be used once and then discarded after re-entry, while SpaceX has focused on designing spacecraft that can be partially or fully reusable. This reduces the cost of space travel and makes it more sustainable in the long term.
- Propulsion System: The Apollo spacecraft used a combination of liquid-fueled rockets and engines, while the SpaceX spacecraft uses advanced rocket engines, such as the Merlin and Raptor engines.
- Landing and Recovery: The Apollo spacecraft landed in the ocean and was recovered by a naval vessel, while SpaceX has developed a system for landing the first stage of their Falcon 9 rocket on land or on a drone ship in the ocean. SpaceX has also developed a system for launching and landing their Crew Dragon spacecraft, which uses parachutes and thrusters for a soft landing.
- Size and Capacity: The Apollo spacecraft were much smaller than SpaceX’s current spacecraft, such as the Dragon and Starship, which can carry more cargo and crew members.
- Technology: The technology used in the Apollo spacecraft was state-of-the-art for its time, but it is now outdated. SpaceX spacecraft use advanced technology, such as autonomous landing systems and advanced life support systems, which were not available during the Apollo era.
