For the first time in more than half a century, humans have travelled to the Moon — and beyond. NASA’s Artemis II mission, which flew from April 1 to 11, 2026, was a momentous and unprecedented achievement: the first crewed flight of the Artemis program and the first crewed flight beyond low Earth orbit since Apollo 17 in 1972.
The Crew
The mission carried NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency astronaut Jeremy Hansen, on an approximately 10-day journey around the Moon. The four astronauts named their Orion spacecraft Integrity — a fitting name for a mission that had to earn its pivotal place in history.
The Moment the World Lost Contact
The most harrowing moment of the mission came on April 6, 2026. As the Orion spacecraft swept around the far side of the Moon along its trajectory, something happened that no mission controller could prevent — and no astronaut could avoid: the Moon blocked all signals between the spacecraft and Earth, cutting off all contact for 40 minutes. All telemetry — the stream of data that Mission Control relies on to monitor the crew’s health and the spacecraft’s systems — went dark.
For those 40 minutes, the four astronauts were completely isolated. No voices from Houston. No reassurance. Just four human beings, a spacecraft, and the vast void of deep space on the far side of the Moon — a place no radio signal from Earth can reach.
It was during this communication blackout that history was quietly made. Soaring some 4,067 miles above the lunar surface, the crew reached a distance of 252,756 miles from Earth — the greatest distance any human being has ever been from our planet. The magnitude of that feat is difficult to comprehend: at that moment, they were more alone than anyone in the history of our species.
When contact was restored and the spacecraft emerged from behind the Moon, the relief at Mission Control must have been immense. The crew were safe, the record was set, and humanity had reached further into the cosmos than ever before.
Splashdown and Return
The Orion spacecraft splashed down in the Pacific Ocean near San Diego, California, on April 10, 2026, decelerating from nearly 25,000 mph — roughly 35 times the speed of sound. The crew were recovered safely and returned to NASA’s Johnson Space Center in Houston shortly after.
After more than 50 years, humanity reached for the Moon once more — and this time, going behind it was an extraordinary achievement that will be commemorated for generations to come.

Comprehension Questions:
1. What made the Artemis II mission historically significant?
It was the first crewed flight beyond low Earth orbit since Apollo 17 in 1972, making it the first time in more than half a century that humans had travelled to the Moon.
2. Why were the astronauts completely cut off from Mission Control on April 6, 2026?
As the Orion spacecraft passed around the far side of the Moon, the Moon itself blocked all signals between the spacecraft and Earth, causing a communication blackout that lasted 40 minutes. All telemetry also went dark during this time.
3. What record did the Artemis II crew set during their mission?
They reached a distance of 252,756 miles from Earth — the greatest distance any human being has ever been from our planet — while soaring approximately 4,067 miles above the lunar surface.
