Returning to the Moon after 50 years: what are the differences between the Apollo and Artemis missions

NASA has a definite liking for the names of Greek gods for space missions to the Moon. First it was Apollo and now it is Artemis, who in mythology is the goddess of the moon and the twin sister of Apollo. In the polytheistic religion of ancient Greece, they represented the opposite, but was unthinkable without each other And the agency may not have chosen their names at random.

From 1969, when the first manned mission to the Moon was launched, until today, Space technology has progressed by leaps and bounds. Although human exploration with Artemis III cannot be considered without the first time an astronaut set foot on a satellite, the differences between the missions are many.

The spacecraft was launched on a Saturn V rocket from the memorable Apollo 11 mission and, until recently, was the most powerful rocket ever successfully launched. Space Launch System (SLS) rocket, which finally took off on November 16, exceeded its data, became “The Most Powerful Rocket Ever”According to Jim Frey, NASA associate administrator for Exploration Systems Development.

The Space Launch System rocket will be essential to NASA's Artemis mission.

SLS is 15% more powerful than Saturn V. free stressed that it is about 39 million newtonsWhich equates to about 400,000 kg-force, enough to drive about 25,000 locomotives at a time.

spacecraft technology

Although Orion and Apollo look alike, the new spacecraft that entered lunar orbit yesterday has a computer that’s 20,000 times faster than its predecessor. Too, 128,000 times more memory Compared to the computers used in the Apollo missions.

In the case of the computers carried by Orion, NASA intends to turn them into the first lunar communications network. your name will be Lunanet And it will have functions like internet with browsing capabilities.


The Mars samples will be sent by rocket to a spacecraft and from there to Earth.

1969 was part of a space race

The moment when the first astronauts set foot on the Moon was marked by Cold War between the Soviet Union and the United States and his space race. Currently, there are still geopolitical tensions between Russia and the North American country, but space exploration is not an important point in them.

Thomas Zurbuchen, NASA’s associate administrator for science, said: Artemis “It’s Not About Flags and Footprints”but to “establish a permanent presence on the Moon and lay the foundation for a lunar base and future missions to Mars.”

Furthermore, one of the purposes of Artemis III would be to, For the first time, a racial man and a woman set foot on the Moon.

Orion will be further away than Apollo

Frey said NASA wants to make Orion the farthest a manned vehicle has ever been: “We’re going to go 64,000 kilometers beyond the Moon with the capsule.” will be specially located About 450,600 km from the earth.

JPL will use the high-performance space flight processors that Microchip makes for future missions.
Astronauts will be more than 450,000 kilometers away from our planet.

They will work autonomously.

more time on the moon

So far, the longest time astronauts have been on our natural satellite has been three days, with Apollo 17 in 1972. With Artemis, NASA has plans Four people are on the lunar surface for 30 days.

As Frey pointed out, explorers would go to the South Pole in search of resources: “We believe there are large amount of water ice Of course we can use it to sustain crew and even separate it into hydrogen and oxygen and make fuel and power.”
