NASA’s Artemis-2 mission has been successfully completed. After a historic 10-day lunar journey, the four astronauts returned to Earth with a safe landing in the Pacific Ocean early Saturday. This mission was historic in many ways and is considered a big step towards permanent human presence on the Moon in the future. A few minutes of communication blackout during re-entry certainly increased the tension, but as soon as Mission Commander Reed Wiseman’s voice was heard ‘Houston, we can hear you clearly’, a wave of relief ran in the control room.

The mission included three American and one Canadian astronauts Christina Koch, Victor Glover, Jeremy Hanson and Reed Wiseman. This was the first time in the last five decades that humans made a flyby near the Moon.

Re-entry is the biggest threat

The most risky phase of the mission was the return to Earth’s atmosphere. The spacecraft returned at a speed of about 40,000 kilometers per hour and a temperature of 2,760 degrees Celsius. It was about 30 times the speed of sound and about half the surface temperature of the Sun. During this time, the Orion capsule was surrounded by red-hot plasma and contact was lost for about six minutes. There was applause in Mission Control after the successful parachute opening and safe landing.

victory over an old challenge

Concerns were raised about heat shield degradation in the 2022 Artemis-I mission. This time, to reduce the risk, the re-entry path was kept shorter and steeper, due to which the mission remained safe.

What is special in this time’s team?

This mission was also special in terms of diversity. Christina Koch became the first woman, Victor Glover the first black astronaut, and Jeremy Hanson the first non-American on a lunar mission. This presents a very different picture from the homogeneous parties of the Apollo era.

New record set

Artemis-II astronauts covered the greatest distance ever from Earth. They reached a total distance of 4,06,771 kilometers, about 6,400 kilometers ahead of Apollo-13’s record.

saw amazing views

During the mission, astronauts took thousands of photographs, including a special one called EarthSat, which shows the Earth rising behind the surface of the Moon. They also saw the glow of meteorites, solar eclipse from space and the far side of the Moon, which till now only robotic missions had been able to see.



Emotional moments also came to the fore

An emotional moment during the mission came when the astronauts asked for permission to name two craters on the Moon after their spacecraft and Wiseman’s late wife.
