Apollo vs Atlantis: What are the differences?
Introduction:
Here are the key differences between Apollo and Atlantis:
-
Historical Context: Apollo was a manned spaceflight program by NASA in the 1960s and 1970s, focused on lunar exploration, while Atlantis was one of the Space Shuttle orbiters in the NASA fleet, primarily used for satellite deployment and servicing missions.
-
Purpose: Apollo's main goal was to land humans on the Moon and bring them back safely to Earth, whereas Atlantis was designed for multiple missions to carry crew and cargo to low Earth orbit as part of the Space Shuttle program.
-
Technology: Apollo spacecraft used expendable rockets and the lunar module for Moon landings, while Atlantis flew on reusable Space Shuttle orbiters with solid rocket boosters and an external fuel tank.
-
Crew Capacity: Apollo missions typically carried a crew of three astronauts, while Atlantis could accommodate larger crews of up to seven astronauts for space shuttle missions.
-
Retirement: The Apollo program concluded with its last mission in 1972 (Apollo 17), while Atlantis had its final flight in 2011 (STS-135) marking the end of the Space Shuttle program.
-
Legacy: Apollo is remembered for achieving the first manned Moon landing in 1969 (Apollo 11), while Atlantis holds the distinction of being the last Space Shuttle to fly, marking the end of an era in human spaceflight.
In Summary, Apollo and Atlantis differ in their historical context, purpose, technology, crew capacity, retirement, and legacy in human space exploration.
