Space travelers on groundbreaking lunar expedition enter fifth day of duties

The Artemis 2 mission's four astronauts have embarked on their fifth day of travel to the Moon, having already witnessed unprecedented views of the lunar surface, with their Orion spaceship approximately 215,000 miles from Earth and 65,000 miles from the Moon.

As they began their day, former astronaut Charlie Duke, who participated in the Apollo 16 mission in 1972, extended a ceremonial wakeup call to the crew, expressing his appreciation for their efforts in building upon the Apollo legacy with the Artemis mission.

n

Duke, 90, shared a personal message with the crew, stating, "Below you on the Moon is a photo of my family, and I pray it reminds you that we in America and all of the world are cheering you on."

Earlier on Sunday, NASA released an image captured by the Artemis crew, showcasing the Orientale basin on the Moon, which has never been seen by human eyes before, according to the US space agency.

n

NASA noted that this mission marks the first time the entire Orientale basin has been visible to human eyes, with the massive crater resembling a bullseye having been previously photographed by orbiting cameras.

n

Astronaut Christina Koch, speaking live from space to Canadian children, expressed the crew's excitement about seeing the basin, often referred to as the Moon's "Grand Canyon," saying it is "very distinctive and no human eyes previously had seen this crater until today."

n

The next significant milestone is expected to occur overnight Sunday into Monday, when the astronauts will enter the "lunar sphere of influence," where the Moon's gravity will have a stronger pull on the spacecraft than Earth's.

n

If all goes smoothly, the astronauts, comprising Americans Koch, Reid Wiseman, and Victor Glover, along with Canadian Jeremy Hansen, may set a record by venturing farther from Earth than any human before as the Orion spacecraft orbits the Moon.

n

NASA reported that the Artemis crew has completed a manual piloting demonstration and reviewed their lunar flyby plan, which includes analyzing and photographing surface features during their time circling the Moon.

n

NASA chief Jared Isaacman stated on Sunday in a televised interview with CNN that the primary focus is on the ecosystem and life support system of the spacecraft, as this is the first time astronauts have flown on this spacecraft.

n

Isaacman added that the crew's experience on the spacecraft is crucial in gathering data, saying, "This is the first time astronauts have ever flown on this spacecraft before, that's what we're most interested in getting data from."

n

On the schedule for day five is the testing of the astronauts' "survival" suits, which are worn during takeoff, re-entry, and emergency situations, such as cabin depressurization.

n

The crew will conduct a full sequence of suit operations, including putting on and pressurizing their suits, performing leak checks, simulating seat entry, and assessing mobility and their ability to eat and drink, according to NASA.

n

Although the four astronauts will not land on the lunar surface, they are expected to break the record for the farthest distance from Earth during their pass around the Moon, with Isaacman saying, "they will be on the far side of the Moon, they will eclipse that record, and we're going to learn an awful lot about the spacecraft."

n

The information gathered from this mission will be crucial for setting up subsequent missions, such as Artemis 3 in 2027 and the lunar landing itself on Artemis 4 in 2028, according to Isaacman.
