NASA's Artemis II Mission Begins Historic Journey Toward the Moon

Kathmandu. For the first time in nearly five decades, a crewed spacecraft has left Earth's orbit, heading toward the Moon. Following a day of orbiting Earth, the astronauts of NASA's Artemis II mission ignited their engines, marking the beginning of an historic lunar journey.

Approximately 25 hours after liftoff, the 'trans-lunar injection' was successfully completed. The Orion capsule, carrying three American and one Canadian astronaut, exited Earth's orbit and is now traveling toward the Moon, located about 250,000 miles (400,000 kilometers) away. NASA official Lori Glaze announced that this is the first time humans have left Earth's orbit since Apollo 17 in 1972.

Confirming the engine burn was a complete success, Canadian astronaut Jeremy Hansen described the view while moving away from Earth as 'unprecedented.' According to him, the crew members were emotional as they watched Earth recede from the windows.

For safety, NASA tested the capsule's life-support systems while in close proximity to Earth for one day before the lunar journey. Only then was the full mission to the Moon authorized. This test is considered a crucial foundation for NASA's long-term lunar plan—establishing a permanent base and ensuring continuous human presence in the future.

Commander Reid Wiseman, pilot Victor Glover, Christina Koch, and Hansen plan to fly close to the Moon, loop around its far side, and return to Earth. During this mission, they are expected to break the distance record set by Apollo 13 in 1970. Additionally, they are expected to perform the fastest re-entry upon returning to Earth on April 10.

This mission has already added a new dimension to history. Glover, Koch, and Hansen are the first Black, first female, and first non-American astronauts, respectively, to participate in a lunar mission. Previously, all 24 people who reached the Moon under the Apollo program were white men.

Glover noted that seeing Earth from space makes all of humanity appear as one, delivering a message of human unity. "We are all one species," he said. Before the mission's critical moment, the astronauts were awakened with music to boost their spirits.

Following final authorization, they were told they were part of 'humanity's return to the Moon.' The capsule is traveling on a 'free-return' trajectory, utilizing the gravity of both Earth and the Moon, with engines providing speeds exceeding 24,000 miles per hour.

Commander Wiseman described the journey as extraordinary and challenging, noting that the gravity of the situation is only now being fully realized. Flight Director Judd Frieling also described it as a once-in-a-lifetime opportunity.

The next critical phase will occur on Monday as they approach the Moon. The Orion capsule will come within about 4,000 miles (6,400 kilometers) of the Moon, offering a rare view of its far side. Additionally, the astronauts will be able to witness a total solar eclipse.

Earlier, while in Earth's orbit, they clearly observed continents, coastlines, and the South Pole. Koch described these views as extremely impactful. NASA views this mission as a vital test for its long-term plan to land humans on the Moon by 2028. However, some technical challenges have emerged during the flight.

After a problem arose with the Orion capsule's toilet, the astronauts resorted to alternative measures. Additionally, to resolve a potential issue with the water supply system, urine storage bags were repurposed for water storage. The astronauts successfully secured over seven liters of water before the journey toward the Moon.

Despite these minor challenges, Artemis II has begun a new chapter in human spaceflight, which is expected to pave the way not only for a human return to the Moon but also for future deep-space missions.
