What milestones did Artemis II achieve on its mission?
We did it. We have returned to the moon. After 54 years, setting foot on our moon had become a distant memory. All that was left to remind us we ever visited was a collection of grainy film reels, some iconic photographs, and a few hundred kilograms of lunar rock. But on the 1st of April, 2026, that changed. We went back. Not boots on the ground yet, but in the vicinity at least. And Artemis II wasn't just a repeat of Apollo. It was a total reimagining of how we explore. From high-definition laser streams to real-time observations of meteors slamming into the lunar crust, this 10-day voyage has revealed our closest celestial neighbour in ways we've never seen before. But every step into the unknown comes with risk.
Between critical engine leaks and malfunctioning life support, not all was as smooth as it seemed. I'm Alex McColgan and you're watching Astrum. Join me today as we leave Earth and head back to the Moon. We'll look at the triumphs, the discoveries, and the narrow escapes of the Artemis II mission, paving the way for our return to the Moon. On the 1st of April 2026, at 6.35pm EDT, the countdown reached zero, and humanity was on its way back to the moon for the first time in more than 50 years. The SLS rocket produced a staggering 39.1 million newtons of thrust. as it set off from the launch complex 39B at the Kennedy Space Center, pushing the integrity capsule through the sound barrier within seconds.
Inside, Commander Reid Wiseman, pilot Victor Glover, and mission specialists Christina Koch and Jeremy Hansen were pressed into their seats by forces reaching nearly 4 Gs. Artemis II was finally on its way. In less than 9 minutes, the crew were already in orbit around Earth, but they weren't heading straight for the Moon. Instead, they spent the first 24 hours in this high, elliptical Earth orbit on a trip designated as a shakedown cruise. This was a critical testing phase, making sure every system was working as it should before pushing on into deeper space. After all, This was the first time four humans were living and breathing inside the Orion architecture. They needed to make sure it was performing properly before leaving the relative safety of Earth orbit.
The crew performed checks on the environmental control and life support system, monitoring the scrubbers designed to pull carbon dioxide and water vapour out of the cabin air, It sounds like a routine check, but in microgravity, carbon dioxide is a silent killer. Without the convection we have on Earth, carbon dioxide doesn't disperse. It pools in stagnant pockets right in front of your face. If the ventilation fails, you could effectively suffocate while wide awake. A sobering thought when you're thousands of kilometres away from any potential rescue. A little over three hours into the mission, the crew also conducted proximity operations, where they used a jettisoned interim cryogenic propulsion stage
as a reference target, maneuvering Orion within close range to simulate the docking procedures required for the Artemis III and IV missions. Over the course of 70 minutes, they repeatedly performed controlled approach and retreat maneuvers, collecting precise navigation data. Out here in space, the crew had no GPS to rely on. only the physics of the engine and the steadiness of pilot Victor Glover's hand. However, even this early phase wasn't without its hiccups. Not long after launch, the crew realised that a valve in their water dispenser had closed itself due to the immense g-forces. A faulty valve meant the crew couldn't count on getting water out of the main tanks in the usual way, so they manually extracted 7 litres of it into backup bags using syringes and straws, just to make sure they would have enough to drink for the rest of the mission.
Even more concerning was a leak discovered in the helium manifolds, a part of the rocket used to pressurise the propulsion system. The leak rate was noted to be an order of magnitude higher than anything seen during ground testing, but thankfully the mission controllers determined it was still within acceptable safety limits.
